I did not mesure for the moment as I did not start the memory speed optimisation yet. I plan to add a small cache for the memory access.

Use this board on a tandy 1000HX will of course need lot of test to compare it vs the tandy 4 in 1 for example.

Hi, My PicoMEM Board si progressing, even if I face multiple challenges. what is new: - BIOS Menu working for disk image, started for Memory detection and configuration. - Selection of HDD image and Boot, working on images up to 4GB - Selection of Floppy image and Boot, was able to Boot DOS 3...

Thanks, so it confirm what I did think.

Hi there. I have a question for XTIDE Specialist. I am working on my Pi Pico based memory and Disk board (For XT Computers) I did implement a BIOS in this board and even if it is located After the XTIDE Bios, it seems that XTIDE Start After my Board BIOS. Then, I suppose that the XTIDE BIOS...

A ROM like this is needed when there is a big problem. In this case, there is a good chance that any video will work. Then, ask for VGA support is the contrary of the ROM purpose....

First time I see a basic command to display a BIOS ram variable :)

One file per sector ? This is strange a single .IMG file is more simple

Hi, There is a subject on it in this forum, but not a lot of interrest on it so far. https://forum.vcfed.org/index.php?threads/picomem-project-pi-pico-on-an-isa-board.1241199/ if I understood well, your board emulate a standard XTA disk, so that the PC can boot on it without BIOS modification...

Hi, Was the version based on the Pi Pico canceled ? I see the teensy design seems to be much more compex that what we need for a Pico. I am able to emulate RAM, EMS, multiple disk on a CF with my PicoMEM. (ISA Pi Pico board)

Hi, I did a pi pico based board emulating ram, ems rom and disk on microsd. Lot more can be done with it. You can search for #picomem in twitter

I originally wanted to do a PiStorm like project. Then, I realized that this project exist, and I prefer to do an ISA Board. With an ISA Board, no modification at all is needed and it is already possible to do lot of things. @MicroCoreLabs Why not comming to our Discord server, we can add a...

Hi Sergey, Just a huge thanks to you for all what you did bring to the 8086 World. Are you aware of the Pi Pico based project going on ? IT can be awsome if you join our Discord.

It is long do write an interface in ASM :(

Surely STPC Industrial, I designed the evaluation/Development board for this chip (Worked 4 years as application engineer for ST)

It is a possibility They already know me thanks to my other projects.

Hi. It is, but private. I am still not sure about how and when to publish it.

416Kb of RAM Added (every single slot of free @ taken, except the one decoded by the XTIDE Board...) 2Mb of EMS Disk emulation based on .IMG files stored in a MicroSD. (Possible to add 4 x 4Gb disk then) Add the memory is configurable in software.

I wanted a project to : - Go Back to electronics - Go back to C programming - Work on emulation - Do something really usefull for the PC community So: 416Kb of RAM Added (every single slot of free @ taken, except the one decoded by the XTIDE Board...) 2Mb of EMS Disk emulation based on .IMG...
