ISA Blaster: DirtyRat Project (USB Mouse on a Pico-powered ISA card in DOS) (Part 2) 

This is a really cool project! I would love to see you swap our the Pico for a Pico W and then emulate an NE2000 network card (or another commonly supported card) to create a DIY WiFi card for old machines

Awesome Job Brotha! Im really wanting to build a Dos Rig. I Picked a PIII a few weeks back to restore with the kiddos

A serial port debugger for your serial port. I love it!

Great to see you persisting at this project!

Tremendous work!!!

awesome work mate!

Fantastic work!

Impressive! Very much appreciated:)

Cool project! But I would like to suggest one change to the design: You can use shift registers to handle the data and address lines and minimize the number of Pico pins needed. The ISA bus is quite slow, there will be no problems with this

Did some testing with Rev. 0.1 boards, the results are a mixed bag. Best results were on a Digis 486NL motherboard, works great with ISA frequency of 6.67MHz or less, at 8MHz has an erratic behavior and also interferes with the keyboard, above 8MHz it doesn't work. It can work without disabling the COM ports on a Windbond Multi-IO card. 386SX board with SCATsx chipset locks as soon as the mouse is moved after the driver is loaded. Doesn't work on a PCChips M520 Socket 7 with 430VX chipset. Tested some mice, works great with Logitech B100, NGS Flame Black and a Wireless keyboard+mouse combo from Ewent model EW3256, some others didn't work. One issue with the Pico reset, had to take the board out of the ISA slot to reset it, if I turned the PC off and then on right away with minimal wait time, the Pico wouldn't work and the led stayed off. Waiting some minutes makes it work again, but taking the board out of the slot is quicker, inside a case is a different story. Maybe there are some timing issues that prevent it to work on 8MHz ISA and above, do you want me to try anything else? Do you have an e-mail address so I can send you some video footage? Thanks. PS: will update this post with more info when I test other motherboards.

486 bus timing can be much faster than standard PC bus times would Playing with the settings in the bios help?

concerning the 456-board. Perhaps the ISA-busspeed is to high or out of spec.

Any chance you would make a Book8088 (or Hand386) version of your PCB like PicoGUS? The Book8088 would greatly benefit from a serial mouse plugged directly into the Book8088 port...

Honestly, compiling cutemouse in dos isn't too bad. Just use dos box and a bat file, I think 2.1 comes with a bat file to use as your base.

How is it working under windows 95 with this driver?

Why not use esp32 which has 20-30 I/O pins?

Could this ISA Blaster be PCI Blaster, would a PCI bus card work in dos?

can you build something like this for a c64? something just like it adding in wavetable perhaps? more sound channels? maybe a better vic II card? more colours, more vram, higher resolutions.

Is that Kermit the frog talking?
