Flash storage for classic PC's - building an XT-IDE kit!

Рет қаралды 63,491

Күн бұрын

Watch me build an XT-IDE kit from Glitchworks designed to give modern storage options to the IBM PC (and XT), then test it out and hopefully get it running! The original PC and XT had an MFM storage interface and an 8 bit ISA bus; the IDE interface was only available for 16 bit ISA and later. This card adds the ability to use more modern options like flash storage to boot an original PC, which has the side benefit of allowing the download and loading of early PC software from a modern PC onto the 5150 and 5160.
This is partially a soldering video, but I do show the card in action as well!
Updated 8/15: I mentioned in the video that I'd give a little more detail on how I had to get the card working. At this point, I have DOS 5.0 booting on the card with a full 256MB partition. What I first had to do was fully clean the card using diskpart's clean command and a total MBR wipe using DOS debug. This part you can do in a VM. Then I was able to fdisk, format /s and install DOS 3.2 from actual floppy disk on the 5150 (disks I already had) to create something at least readable by both the 5150 and a Windows 10 PC. I then used that to transfer DOS 5.0 disk images from my modern PC to the 5150, and I used dskimage.exe to extract them to actual floppies. Then I booted DOS 5.0 from my new floppies, exited out, used fdisk to delete the non-DOS partition, cleaned the card yet again (probably a little redundant but I wanted to be safe), then booted from floppy again and went through the regular DOS 5.0 setup (including creating a new partition). Then the card worked and now has DOS 5 on it, with full use of the card. Bottom line is, as far as I can tell, you really need to install DOS from physical floppies. (An emulator should work too, but they're not easy to get working on a 5150 either.)

Info about MBR zero data using debug: minuszerodegrees.net/ibm_xebec... (ignore step 1 and skip to step 2)

You can buy XT-IDE cards at the Glitchworks Tindie store: www.tindie.com/stores/glitchw...
And here's the CF adapter I used: ebay.to/2P04p4C
Don't forget that you will also need a 40 pin straight IDE cable!

The first thing I noticed was the RadioShack solder and instantly got sad. I never knew how much I relied on them until they were gone. Rest in spaghetti, never forgetti.

@ModernClassic 6 жыл бұрын

Yeah, I actually like that solder! I have another spool I got from Mouser that's smaller diameter and technically more appropriate for something like this, but it just doesn't work as well. I think it's the flux; the RS solder just has a lot of flux, and it seems like good flux. The other stuff I have also has a flux core but it just doesn't stick unless I manually flux up every surface before soldering. I've been wondering what to buy when my RS solder finally runs out.

RIP Radio Shack. I still have some of that Radio Shack solder and a number of pig tail cable repair parts, switches and adapters. Those days of having a local place to run out to for a part at the 11th hour are sadly gone. Most nostalgic of all, my old and beloved Tandy 286...ahh the memories of my first PC 😢 I'm gonna go give her a boot up just to listen to that lovely loud HDD and PC speaker post tone!

FYI: Several manufacturers did make 8-bit IDE-XT hard drives and interface cards (not to be confused with this XT-IDE card) in the late '80s and early '90s, but there were multiple different proprietary interfaces in use, so an IDE-XT drive from one manufacturer wasn't guaranteed to work with an IDE-XT interface card from another manufacturer. And only one model of these drives (the Seagate ST-351A/X) was also compatible with the "normal" 16-bit IDE (a.k.a. ATA) interface. But nonetheless I do have Seagate IDE-XT drives in several of my Tandy 1000 systems and they work just fine.

I do not recall which card I ended up with, but I did have an 8-bit IDE host adapter in my 1000 TX. Possibly as early as 1990. I also had the 768k ram expansion, a mathco, and I think an RTC. I dug that 'superior' PC Jr. clone of the Tandy.

The 80s were an interesting period in PC hard drive interfaces, in the course of that decade I used MFM, ESDI, SCSI, and IDE driver interfaces in my various PCs. I’m not even sure most of that era even remember the ESDI interface that was an intermediate interface technology between the aging MFM and SCSI/IDE which were still maturing at the time.

Indeed, it was common to see SCSI systems with an ESDI drive and a SCSI to ESDI converter board bolted to the drive.

The ST-351A/X was also one of the last 40 MB stepper-positioned drives made, too. I don't know if that contributes to their seemingly higher-than-average survival rate, but they do seem to be tough little drives. I've found more of them in 16-bit ATA service than 8-bit XTA service.

I haven't looked into how the PC does it too deeply, but the Apple II and various other computers also used artifact colors, so unless the PC's doing something really different but called the same thing, it seems like it was a pretty common hack at the time. The only reason I can think of it not being widely known on the PC is that most people probably used the official monitor with an RGBi connection - I don't remember ever seeing anyone connecting a PC with a composite connector in the 80's.

Hey guys! Several people have actually commented about the size of the solder I'm using, so I may as well pin my answer. I do have thinner solder that's probably more technically appropriate for this purpose (the spool is behind the flux in the shot when I'm tinning the tip), but I intentionally chose to use thicker stuff. It has a thicker flux core and makes it easier to finish jobs like this quickly, because I don't need to manually flux. And it works. It might not be as pretty as the stuff you've seen working at an electronics company, but that's not the goal. The goal is to have fun making something that works and show you how to do the same, and that was the result here.

@SianaGearz 6 жыл бұрын

That explanation doesn't seem to make a lot of sense, as the amount of flux does not depend on the solder thickness. 2% flux in 0.5mm solder is not too uncommon. Not that you're wrong in using the solder that you happen to like, after all the thin solder you have just might not be very good to work with for a variety of reasons, just poking holes in the logic. I find thin solder to be faster as it will start melting quicker and release the flux very easily. At the end of the day your soldering is perfectly fine, it doesn't look machine made, but there's absolutely no reason to suspect that it will fail.

@rokero171 6 жыл бұрын

I always use 1mm flux core solder, and never had a problem, perhaps your thin solder wire isn't good, or is an older spool that isn't good anymore...

Using a bigger gauge for solder isn't an issue; there difference mainly comes to how fast you need to feed the solder to the joint. It can be easier to control the amount of solder with a smaller gauge, but at the same time if you're careful, there's nothing wrong using something bigger.

For breaking apart the jumper strips I would suggest you score it with an xacto first on both sides - it will increase your odds at breaking it at the right count but also in the center of the gap...

@ethanpoole3443 6 жыл бұрын

Brian Ullmark Actually, there is no need to score if you use two pairs of pliers, one grasping to either side of the crimped area between pins and then quickly rotate one of the pliers just a fraction of a turn, you will get a clean break every time because you concentrate all the force on the built in weakness between pins (it’s an even more helpful trick with the double pin header strips). Even just securing one side rigidly in pliers and then using your hand for the other half greatly improves the chance of a clean break without having to score the break point, though double pliers is still the more reliable method with the double wide header strips.

@budude2 6 жыл бұрын

I guess each to his/her own - been doing it that way for many years and it works for me anyway. With that said - either way is better than just snapping them apart with your fingers alone.

@glitchwrks 6 жыл бұрын

I use pliers to hold the section that's being broken off, and start with the 2-pin segments, then the 3-pin segments, so you're left with a 10-pin piece to break into half for the two 5-pin segments. Breaking the short ones off first gives you more leverage. But everyone builds kits differently -- cutting with an X-acto knife or snipping them apart with side cutters works, too!

Hey, that looks familiar! :) Cool to see a video of the assembly process! You can also buy kits and whatnot on Tindie, aside from supporting a cool trading platform largely targeted at open source hardware, some of the stuff is cheaper there due to lower Tindie fees. And, since there's sometimes questions about it, the kit is *significantly* cheaper than the assembled board not only due to assembly/testing times, but because I actively want to promote hobbyists getting DIY kits and soldering them up! There's a manual in the works, it's not done yet. W.R.T. initial bring-up of the card, you need to erase the CF card, and then do the partitioning and formatting on the XT-IDE. The XT-IDE doesn't have to be installed in the target machine for that, you could for example use a Pentium 3 with ISA slots and it'd work just fine. I'm also working on a CF adapter that bolts to any XT-IDE that uses the Keystone 9202 ISA bracket. That'll free up your slot occupied by the CF converter. Since it'll be supplied as a module, like the Slot 8 Support board, I'll be able to offer it with the surface mount soldering done already so that kit builders who don't want to attempt surface mount can still build the main XT-IDE board themselves.

On an XT I'd probably get flash storage *and* a real hard drive working, both because XT's typically came with hard drives and also because they have 8 slots to let you do that. Since the original PC never came with a hard drive and my memories of them are of just fan noise, I actually feel like it's more historically accurate to ditch the hard drive in this machine.

This was an extremely useful video to me, as I was just struggling with trying to get XT-IDE card working with my CF Adapter, I even used the same CF adapter! It's annoying that I have to find an original copy of DOS for it to work, but I guess its always interesting to have the physical disk. Also, do you know what the power input on the CF adapter is for? I thought that it must be necessary for the card to work, but given that you didn't need to use it, I assume that it must just be for if you plan to use a slave drive.

@ModernClassic 6 жыл бұрын

The power input is there for controllers that don't supply it via pin 20. One of the jumpers on the XT-IDE is actually to set that. So if you have a CF adapter that can't take power that way, you can change that jumper, and likewise on the CF adapter, the port is there if the controller doesn't support it. Luckily in this case both do.

@ModernClassic 6 жыл бұрын

A 386 is probably already using IDE, unless it's an IBM PS/2. And with the same exception, it'll at least have a 16 bit ISA bus. So you can just get a standard IDE controller if you for some reason need one; you wouldn't want an 8 bit one anyway since it'll be a lot slower. If you want to use CF, you can just get the adapter by itself and a CF card. You should be able to hook up the current drive and CF adapter in a master/slave configuration to copy the current drive to CF before removing it. (If you want to remove it; I'd recommend at least backing it up this way regardless.)

I have 2 x 256Meg CF card with just dos 6.22 and all of my floppy images and popular apps and games, the other CD card is 4Gig, it is Partitioned into 2 x 2g with win98, the machine runs perfect in dos mode or straight into Win98.

Shame I already spent pretty much my retro budget for this month so I suppose the XT will have to wait until next month or so before I'll be going back to that. Just a question, what CF card are you using? Since with CF the card can actually make the difference between it working in a solution like this or not (since the CF card is the part that should correctly implement the IDE standard and apparently some newer cards don't do this correctly)

To get my system to work I partition/formatted a 32 meg CF card with a DOS 3.2 disk and then installed DOS 5.0 to that partition. Then I added a second larger CF card and partition/formatted it with the DOS 5.0 install. So I ended up with a 32 meg C: drive and a 256 meg D: drive

I don't mind just blowing up my current partition to make one big one now that I've backed it up to my modern desktop. My current problem is just that I don't physically have DOS 5.0 and can't easily get it on this machine without just buying a real copy of it on 5.25" disk. I'm not sure what the Tandy 1000TX supported, but the original IBM PC was pretty limited in its storage options, including floppy support, or I'd just use a floppy emulator or make disks on another machine. I'll figure something out, though; I'm still running through my options trying to do it for free with what I have, but if I have to just buy real disks, I'll do it.

Possible fix to using 2 slots. since the IDE card is oriented for XT/AT/ISA, and the CF adapter is oriented for PCI, could you get away with not using the bracket on the IDE card, and seating the CF adapter in the same slot?

@ethanpoole3443 6 жыл бұрын

Sarreq Teryx If he did not mind the CF card being internal (and less accessible) then there are other options as well, such as plugging an adapter into the IDE connector or modding the rear of the chassis with a slot for the CF card and eject button and just mounting the CF card adapter to an open area on the rear of the chassis. Or even spinning a version of the ISA adapter that includes an onboard CF or SD Card slot (though CF is much easier to interface with IDE since CF Cards are just a miniaturized IDE device).

Modern Classic : one hobby tip for you when you solder DIP packages. solder pin 1, then solder opposite pin, then reheat each pin while pushing on the component, so the DIP is tighten to the board and then you can solder the rest of the pins. for pin jumpers, have a bunch of jumpers to hold the 2 rows together while soldering. And finally, the top tool for soldering : FACOM 153 Brucelle

I remember going to a local ComputerLand store asking if they sold bare drives and after them asking me what I was trying to use one with, they said, "You can't connect a hard drive to an 'Artari'" and that I needed an IBM PC or Mac for that.

I usually find myself being unable to tell the colours apart on resistors unless i use a lot of magnification. Another pet peeve of mine are cheap 1%/2% resistors which are... good, except the spacing is wrong and you can read them from both sides, but only one of two values is correct! I find it best to just measure every single component that can be measured before i mount it, takes a second, faster than reading really.

Since the ide connector on the adapter board just sticks straight out the back if you ever wanted to reinstall the serial card all you would need to get is one of those straight ide to CF adapter boards and plug it in. It would just internalize the flash and make the formfactor more like the hard drives.

3:02 A better camera angle could be from the other side of the table _(so you see the yellow attention label in the left of the frame)_ 4:34 I think the best order of soldering... er SODDERing... a chip is first the first pin, then then last pin. This way the chip is more flush with the circuit board. 8:54 Great SODDERing job. I would have done a far worse job. 16:13 Maybe... just maybe... it stores references to absolute paths. I mean, when you copy _Paradox_ from a drive that once was a C: drive to a subdirectory on a D: drive, it just lost the paths. Maybe it can be fixed by editing some config files. But yeah, where to start... But hey, great video. I don't have old _museum-computers_ laying around. So, I love watching the ones that are recorded and put here on YT!

Hardcard is not MFM but something proprietary. Fun times I had when I was asked to back up the media from such a card a while back. Luckily those hdds are still "ok" with being opened for a short timespan and it just had the issue of the heads being stuck in the parking position. Used an XT-CF as a replacement. On the IBM 5155 I serviced I had DOS 3.2 as the original system running and a copy of DOS 6.22 just in case. Both were installed on different partitions which could be selected by setting them active. Keep in mind if you use DOS 3.2 with Windows7 or higher, it will detect the FAT12 as a faulty floppy (as FAT12 remained the choice of partition type for pc floppies) and fuck up things.

It's actually an MFM drive with an RLL controller, which is one reason why they're so unreliable.

@TzOk 6 жыл бұрын

Every HDD since ST412 has been using MFM read/write method with an RLL encoding. Early drives were using RLL 1,3, later ones RLL 2,7. Only a SD Floppy Drives were using FM instead of MFM which is RLL 0,1. IDE drives also use RLL encoding. In the ST-412/506 times there were technically no difference between MFM (aka RLL 1,3) and RLL (aka RLL 2,7) drives. Some drives were certified as RLL capable, but in practice there was no difference between ST-251 and ST-277R (there was a ST-251R which was a different drive). The capacity and transfer rate were only dependent on the controller used.

Someone recommended that I use a compact flash controller, and when I looked that up I found this. So does this work with the original 1981 bios chip, or does it require an upgrade to revision 10/27/82 as it does with a "regular hard drive", and also, in general, does it work on an original 5150 without any upgrades? In your reply can you also state all of the components needed and their specific models, and even possibly a few recommended compact flash, (I plan on using DOS 3.0)? EDIT: I just found out about www.xtideuniversalbios.org/, are any of the files compatible with the original IBM PC, with the original bios chip? I noticed that all of the bin files mention XT AT or 386 (one doesn't, it is contains the text "tiny", even the card and BIOS itself have XT in the name. But based on even more information that I just found, monotech.fwscart.com/XTIDE_Deluxe_Bootable_ISA_CFIDE_Interface_Card/p6083514_19478732.aspx the BIOS is specifically on the card, and does not replace the PC's bios, but would the all CPU compatible BIOS option be correct if I want it to work with a 5150, and what is recommended for the EEPROM type? Will this even work on a non-otherwise upgraded Original IBM 5150? Hopefully last edit: An eBay seller of a card mentioned this in their description "8088-based computers are picky about the type of CF card used. They will require an IDE/PATA hard drive or a Memory Partner, WinSystems or SiliconDrive CF card. The free included CF card isn't compatible with 8088's." interpreting

Great video, saw you had a spool of Radio Shack solder. Good show! You did a great job of soldering, everything works and that is what is important. If you want more control over how much solder you put on a part go with a thinner diameter solder. .8 mm or .6 mm diameter solder will improve your results dramatically. You will have to feed more solder to the joint but you can control how much you put on the joint. Also, I saw the old dreery "C>" and you should add to your Autoexec.bat file "prompt $p$g" (without the quotes) this will show you what directory you are in on the hard drive as you are moving around in the directories.
