It's time for another awesome software defined ISA card using a Raspberry Pi Pico RP2040: The PicoMEM. This card does far more than just add memory to the computer, it adds just about everything you might possibly need for your old 8088/8086 based system!

It turns out that there is already a TSR for the PicoMem that allows you to switch floppy disks while booted into DOS. The TSR was part of the utility package on the Github repo. Freddy is also working on enhancing the Wifi features in the BIOS to provide more feedback than the current "no feedback" approach. The thing continues to improve!

I looked on FreddyV's github but didn't see the utility package you are referring to. I grabbed the floppy disk image sv86-720.img but didn't see any prg in the image that looked right.

Thanks for the informational video. I’m sure about what I’ll be buying this summer! Perhaps your “communicational lines” towards Freddy are a bit shorter than mine, so could you check if it’s possible to/works to put two (or more) RP2040’s on one card and make them work together, just to make sure they’re able to manage when handling those extra MHz-es, one Hz at a time. “RP2040-SLI” if you will. I’d love to see that! :)

@DropDeadFrederick Ай бұрын

It'd be great if there was a display that'd connect to the picomem VIA the i2c interface that'd give you an LCD screen with some buttons that'd let you swap disks that way. Mount the LCD screen either in a 5 1/4" drive bay or some other location where it's easily accessible. Not everything plays well with TSR applications so having the option to have a separate LCD controller you could hook up would be great.

Hey Adrian, I just got my picomem last night and was trying to sort out why it wasn't saving my BIOS (didn't have the SD card in it.) So thanks for this timely video. I looked on the github page and couldn't find the TSR you were talking about. I also looked in the HDD Images and sv86-720.img floppy image and could find the TSR prg there either. Can you give some more info on where that TSR prg is for swapping floppy images?

Not going to lie - it is epic that there is still a community that is dedicated to keeping all kinds of old computers running so that people can either relive their memories from way back in the day or that younger generations can experience what computing was like at that time. But regardless, it makes me chuckle that you basically plop in a card that has a computer on board which in itself has orders of magnitude more "computing oomph" than the original computer it gets plugged into. Even being on the very low end of the ARM spectrum, that little Cortex M0+ on the Pi Pico dwarfs an 8088 or 8086 no problem...At the same time, seeing the price of the Pi Pico, compared to what a PC cost when it was current tech, shows what giant leaps in development happened since.

@JH-pe3ro Ай бұрын

There's actually two things that are really interesting about having the option of a new board with an MCU - first, that hobbyists can make new add-on cards without much difficulty now, and second - that for any given computing architecture, we can upgrade it to the level of that card. That removes any vintage limitations - the capability of all the computers is all "at the same level" now, limited just by development time. You can make this kind of upgrade for a PC, or an Apple II, or an Amiga, or anything else that you could figure out a way of shoehorning in, and you can make upgrades that copy the capabilities associated with one to the others. It inverts the usual thing of having to make software drivers that deal with hardware: a piece of "smart hardware" like this can act as the driver for something like a USB mouse.

This thought crossed my mind a couple of years ago when I bought an Atari 800XL with a FujiNet device. The FujiNet is just a relatively tiny device that plugs into the back of the computer and seems like just a peripheral that's helping the computer out a little like an extra hand on a person, but really it's taking data from a network or an SD card and running circles around the Atari with its processing power to dumb things down to a level that the Atari can easily handle. It's more like the Atari is a peripheral for the FujiNet simply for the purpose of giving it a more nostalgic interface rather than simply using an emulator.

Neat to see a Leading Edge here. It was my first XT clone PC when I was a kid - though I had the older Model M. It was enough to pirate a bunch of CGA games from my friend whose dad had nearly every PC game in existence going back to the original IBM PC days. When I got a newer 486, I took the Model M and threw it out of the third story window of my parents' house onto the driveway to see what would happen. It landed flat with a huge smack, nothing fell off or exploded out of it. I brought it back inside, hooked it up, and it still worked - except for the hard drive. That thing was pure steel like a tank, like so many PCs in those days.

This is cool. Nice to see convergence like this. In the day I wanted to know every last aspect of the PC. I got too busy to do that. I'm amazed at the detailed knowledge necessary to implement this idea! PS, the right words for LIM (Lotus-Intel-Microsoft) memory is "expanded". You can't get "extended" memory on less than a 286. EMM386 has options for dividing memory into expanded and extended memory side by side. The "/noems" switch prevents the default allotment. The earliest essential use of extended memory was in Netware 286. There was an DOS executable that did nothing but switch to protected mode and set up a large flat model address space for the OS to inhabit. Actual memory protection was not required and not used. That was essentially the birth of the practical LAN.

Getting to the back of the machine to change out an SD card would be a serious PITA where I have my 5160 set up. I like the idea of this card though, and might consider it in future for another machine! Good job!

I may look into one of these for my PS/2 Model 25- when I get the thing back together. NTP support would be really nice in the future. I don't remember ANSI.SYS being terribly slow- at least in DOS 4.01 which is what I had on my first PC. My 5150 is currently running PC-DOS 2000.

That thing's pretty cool. I hope a 16-bit ISA slot version gets released at some point. I don't personally care about XT-class machines; they're too slow and limited to do much with. But a lot of those features would be really handy on an 386 or newer, especially one with limited room for ISA cards like my Toshiba T5200.

Especially if they can add a CD-ROM emu where you can load CD images on virtual drives like they've done here with floppy and HDD. Man that would be cool. Absolute epitome would be an easy way to connect full powered Pi for MT-32 midi emulation. Feels like the sky's the limit on this whole concept.

I'm building an A8PicoCart, a software defined Atari 8-bit cartridge. I've also seen SIDPICOs that use the PICO too. They are $3-5 for a 16MB version. Supercheap.

As a vintage comp user, my tandy 1000RL-HD only has one ISA slot, so while I would like to spend 100s buying the whole line up, I couldn't use them all and couldn't afford them all, this picomem is my saviour...

Hi, Please wait a little until I add support for Tandy 1000 (In my short term objectives)

I don't think this card "obsoletes" a bunch of cards, what it does is make these capabilities available via modern components. The biggest problem I see with "Adlib" cards is getting the sound chips. If the Pico can emulate the sound chip, and it can emulate the 5v chips of the XT IDE, and it can emulate other peripherals, all while using a software designed "hardware stack", that's great. It would be interesting to see someone emulate an XT from scratch with video support on a Pico, then maybe tie multiple picos together to make a modern hardware emulator? Yeah, at that point it's not far removed from Dos Box, but it's still hardware and that scratches an itch that Dos Box doesn't.

@@freddyvretrozone2849 That's really cool, so you will go into the Phoenix-like BIOS and can change the floppy image there? That is neat! Oh and btw, do you have any idea where I would get that "tools" disc that Adrian always uses with all the test software on it? Just playing around with PCem, just found that and the ROMs and having a blast! :D

Hi, Thanks for your comment. I Used the Pi Pico because I think that using a Pi 4 in an Amiga is overkill.. A Pico is a microcontroller, with less RAM than the PC and one entire core is just used to do the communication with the PC. (There is no FPGA, no CPLD) Have expansion with faster CPU than the main machine is not new. The Pico has the same CPU as the Gotek, and nobody noticed that the Gotek is more powerfull than the entire PC. The Commodore 64 Floppy drive contains a C64 motherboard, nobody complain that C64 Floppy is as fast as the C64. The Sound blaster has a microcontroller, ... The modern graphic cards are more powerfull than the PC.

I had a leading edge growing up. A later 386 model. We had it up until like i dunno 1999 or 2000. It couldn't do a whole lot but I was also too young to know how to get it to do much. I did pick up a fair bit of shareware off of AOL though like ant attack and empipe.

@jeromethiel4323 Ай бұрын

I think the best use of this card would be for testing. Because you could drop it into the machine, and have it emulate a lot of stuff, meaning you only have to troubleshoot the MB or video card, or sound card, or whatever without worrying about other vintage parts not playing well with others.
