Back in the 80s and 90s, it was common to use SCSI devices on Macintosh and Amiga computers. Can we use these on Windows 10 and MacOS in 2022?

AND its all a cluttered mess. This is one instance where the streamlined consumer standards surpassed the pseudo professional standard. IDE/PATA might have been a mess at the beginning (reflection, timing,...) but the standard ripened quickly and drives in excess of 400GB were becoming available fast. And SATA 150/300/600 was the final strike, the cluttered franken U.2 connector is another bad example of pseudo server grade standard. Anyway, I'm no friend of NVME M.2 as its a mess too with its horrible keying A, E, B, M but its the future, size wise, speed wise, feature wise.

You'd asked why we didn't see more of these adapters anymore and I think it's just a consequence of it being the nexus of a) reading/imaging SCSI drives is the kind of thing you'd ask someone with technical know-how to do b) the person in (a) is likely to look at their options and realize that it's easier to add a SCSI PCI card to a spare Linux box than buy one of these USB adapters (especially for scalper's prices) When they were still new I'm sure you'd had a lot of semi-technical people that needed to do SCSI-to-iMac/non-SCSI PC migration but today it's like a niche within a niche. Also: it looked like that dd error you'd seen happened at the end of the drive. It might have been that dd just 'ran off the end of the runway' as it was making that image rather than there being an error. Great video as always!

If you ever have a situation where you don't have working drivers for modern windows, it's very easy to set up a VirtualBox VM with e.g. Windows XP and route the USB device to that. You can also setup shared folders to easily transfer over any data or other stuff you might need to interact with the device. Much more convenient than using a seperate machine and USB dongle. Saved me a couple of times with an old printer, and also with my super old IP security cam that only supported super old Internet Explorer.

USB MSC (Mass Storage Class standard) is actually tunneled SCSI commands through USB and all thumbdrives actually emulate the SCSI command set, just over USB requests instead of a SCSI electrical connection. So it's not too surprising that this adapter just implements MSC standard and as such should work out of the box.

Try 2+ and if they all work that would confirm this. I beleive this is why SCSI allows 7 devices, it's actually 8 but the controller itself is always one of them (or something like that - it's been a long time).

I had one of these back in the late 90’s back when Apple released the iMac G3 without SCSI support (only USB and later Firewire 400). Apple was discontinuing SCSI support in all it’s desktop and laptops of the time with the Powerbook G3 (bronze keyboard) being the last Mac to include an SCSI port (discontinued in Jan 2000.). My dad got an iMac G3 in like 1999 and I got a Berlin SCSI to USB with Term Power adaptor they made back then (now discontinued). You can still find the manual for it online on Belkin’s website. It, like many Mac compatible accessories of the era, came in a translucent plastic casing to match the translucent cases of the iMac G3, iBook G3, and Powermac G3 lineup of the era. Mine came in translucent green and white. I haven’t had a need to use ion a long time and I don’t know that I could get a driver for it that’s compatible with a modern Mac or PC for it so I’d have to most likely run it on legacy iMac G3/G4 hardware running an older version of macOS running the Mac OS 9 and early versions of Mac OS X. As you said in the vid, the Belkin model I have is indeed the same white label as yours (just rebranded) made by Shuttle Technologies for Belkin.

Always fascinating, what tech you're getting in your hands sometimes 😄👍! My two cents to clear up two minor details: - Max disk transfer speed over USB 1.1: The max theoretical speed is 12 MBit = 1.5 MByte / second, but after all overheads, the best I've ever got effectively (from various thumbdrives/card readers/external hard disks) was _exactly_ 927 KBytes / second, sustained, with the occasional dip down from that (at least according to the file copy dialog of - I think Win98 at the time? Maybe not the best measurement tool in the world, but anyway...) - That read error at the end of your dd image of the Amiga disk: if dd for Windows behaves anything like the Linux tool (and it should, after all 😄), there's nothing to worry about - you set your dd to a blocksize of 512k ("bs=512k", bigger block sizes than the standard - single bytes, I believe? - give you better transfer speeds), but after so-and-so-many blocks of that size, at the end of the hard disk there just aren't enough disk sectors left to fill up the 512k block, so you get what's there, plus the error message to your console. Perfectly normal behaviour, but if you're not used to it, it can throw you off way more than it should... Thanks, and keep up the good work 👍!

About the error the 'dd' command line tool gave on the read: At least the *nix dd always stops whenever it can't read, or write, the next block. The most common cause of that error is that it has reached the end of a device, and so the next block doesn't even exist. If you got the right number of blocks, everything worked perfectly!

It wasn't until the "burn safe" drives that IDE became capable of doing a decent CD burn.

Then you have to worry about active or passive termination, make sure you don't have different SCSI IDs on the same bus, and that the drive doesn't have the same ID as the controller. Sheesh, all that just to connect your computer to a HD! So yeah, compared to IDE, which had one connector (but evolving electrical and data transfer modes that were backwards compatible) SCSI was a lot more complicated. Parallel ATA you just plugged the thing in, and the hardware figured out how to talk to each other.

Hi Adrian! As I watched your Video about your USB SCSI Hostadpter I started to remember some LSI Controller which only scanned for other id's if it found a device on id 0 and otherwise disabled the scan function. Perhaps the controller in the USB Dongle was developed with the same mindset. While I am writing this some other behaviour of Dell Servers sprung to mind which automatically adressed the controller on the first free id after the highest id of the bus. SCSI brings back memories for me. Keep up the excellent work!

From my personal experience (im from Greece), back then SCSI was not uncommon in PC's but it was used for specific applications, and naming two of them here, mainly for early CD R/W drives and flatbed scanners (and similar devices like Fuji/Kodak film developing/printing machines). I had in 1996-97 a Pentium 120Mhz PC and a Agfa Snapscan fladbed scanner, which was connected via an ISA SCSI card. Later I installed a PCI Adaptec card. When my Agfa flatbed scanner died (in the mid'2000's) I sold the PCI Adaptec SCSI card to the owner of a photolab. He operated a Fujifilm machine which needed a SCSI interface and he could not find one.

When you are looking for a driver that isn't readily available, get the device hardware ID from device manager and search for it in the Microsoft catalog. You'll usually want to start with putting the whole ID in, and back off from the end of the ID to the character before each ampersand until you find a search result, e.g. the rev number is often at the end, and you'll usually want to remove that, hit search and keep backing off from there if no results are found. I usually extract the files from the cab instead of installing the cab directly so I can test if the driver is actually correct.

Cool Video Adrian In circumstances where old hardware wouldn't work under Win10, I've had good outcomes by setting up Virtual Machines and using USB passthrough from the host to the VM.

I think the reason you don't see a lot of solutions that provide a SCSI adapter via USB is there's already good solutions available via cheap PCI/PCI-X cards that'll do this. You can still buy a cheap card new for like $35 that'll do SCSI. It'd still be nice if there were just an easy USB solution though. There's generally Linux drivers available for these cards as well. Linux has supported the Amiga FFS for ages, so you can just directly mount the drive rather than having to copy it. It also supports HFS+, so you can also mount Mac drives directly as well. I managed to mount my old Amiga drive on Linux maybe a decade or so ago by doing this, and it was fairly painless. One suggestion I had while viewing your video.... install Virtualbox on your bench PC, and put some old Windows OSes on them. Then you don't have to mess around with finding "some computer that has the right Windows OS installed". Which is the real problem with Windows, since it's a huge moving target over the last 20 years, so hardware becomes obsolete as they've changed their driver model so many times. That's where the OSS model has shined. I can still just plug in a card from 1999 into a modern PC running Linux, and it "just works". No fuss, no muss, no messing around trying to find some sketchy driver from some weird website somewhere.

I had the same problem last year trying to read and write LTO-4 tapes: Used tape drives from servers where pretty expensive but the worst part was that they all used SAS (Serial SCSI) and PCIe to SAS cards are veeery expensive (I've seen used ones go on eBay for easily +150 bucks). I was about to give up when, casually browsing eBay, I came across a cheap LTO-4 drive that strangely enough appeared to have SFP fiber optic modules on the back. That was my discovery of Fiber Channel (AKA how to connect SCSI devices to a computer three stories up or down or in the next building). That drive came from a tape library, which is basically a jukebox for hundreds of terabytes of tape cassettes and is also far too bulky to be put in the same rack as your backup server or whatever else needs to read and write your tapes. My question then was "If PCIe to SAS cards were expensive, how much could cost a Fiber Channel card?" The answer was 5€ plus shipping. Apparently nobody gives a damn about used Fiber Channel hardware, probably because whoever uses Fiber Channel works in far too enterprise environiment to even think of using used hardware.

Here is the likely reason I think these devices (SCSI to USB adaptors) remained on the market for only a short time. On the Mac side they where only mostly likely bought by iMac G3 users who had older SCSI devices from a older Powermac computer. Powermac G3 (Blue and White) users could as I recall buy an internal SCSI PCI card just like WinPC users did back then if they needed SCSI support. On laptops, SCSI PCMCIA cards did exist for PC (and possibly Macs?). I think the reality was that while some legacy SCSI devices users needed a device like this, many consumers just upgraded to USB and Firewire external devices rather then try to get older SCSI devices to work with Macs or PC’s without built-in SCSI support. So there really wasn’t as many people needed SCSI to USB adaptors as you might think or at least not for that long.

@bobblum5973 2 жыл бұрын

I think one of the main reasons the adapter worked so well is just the fact that backwards compatibility was built into the SCSI interface, command set, and the USB standard as well. The drivers for the devices have more and more been included in later OS versions, so it doesn't have to search online for it. Unusual devices don't have that benefit, plus driver support of 32-bit on 64 and 16-bit on 32-bit OSes makes it harder as well.

For years I've tried to see if I could get a Microtech USB-SCSI-HD50 adapter cable like yours to at least light up (!) Less years ago I ran into a Zip 100 Plus that had a Iomega 50HD to 25D adapter as well as the Autodetect cable. Seeing the adapter 50HD, it looked like the Microtech from memory. So I got it and yes, it did connect. Not know anything, hooked everything up and no dice. But your discovery that has to be SCSI ID 0 is a game changer: The Zip drive has an ID switch for either 5 or 6 so that probably means it won't work even if it provided the termination power. I do have a SCSI tape drive somewhere and maybe a cable for it, but it's basically a project's effort - so I guess for now, everything goes back in a box and a year from now I'll try again - probably when I run into that tape drive or SCSI cable and PCI card wherever they are hiding.

Also another thing that would have been cool to have (that I'm pretty sure doesn't exist currently) is a portable "NetBoot" device you just plug into a router/your iMac G3 and once setup with a drive image you can boot a iMac G3 from it (or just about any Mac that supports NetBoot). It would be super niche though. NetBoot as far as I know only exists as a part of Mac OS X and you have to machine running Mac OS X with Netboot setup connnected to the network to have another Mac boot from.
