Some more comment about the question "Why Pi Pico" I did research based on the PiStorm, so I wanted first to try on Pi Zero 2, but these are just not possible to buy. I was also suprized that the PiStorm need an FPGA with High Speed Pi3/4 So, I hearded about the PiGUS, then the PicoGUS and I started …

Nice project! When USB mouse/keyboard or network is also working I am surely interested in making/buying one. A CD-ROM emulator is certainly a killer feature but I guess a Pico would probably be under-powered for such a feature. Hi, NE2000 network is now working (With Pico W), but not fully …

Really nice! I'm most interested in the EMS support upto 4mb. I have a lo-tech card in my NuXT which I use quite heavily. Ideally I'd love a 8-16mb EMS card so I could push it in a corner and forget about it.. yes I know EMS can go upto 32mb.. but I don't think I'd benefit from more than 8mb. Very …

Hi, The problem of the Stereo on one is that there is a need to write to a register to select the channel Right/Left Instead of just alternate the channel each time a data is sent for example. The 2nd problem is that the PC need to program a timer at the output frequency, this is extremely slow, …

What version of ModMaster should be used on XT 9.54 with Nec V20. To my ears the 2.2 XT sounds pretty good on CT4170 in EuroPC. glx_cga produces strange crackeling noises while playing mod-files. this is gone using modmaster. so thank you for this nice software! Did you succeed to have it working ?

I released a "Test" version of the Mod Master XT 1.01 executable. It correct the BlasterBoard 2.0 detection problem. But the best is to update the BlasterBoard to the last version.

Very nice proyect!. A lot of cool features. In my experience and needs... (trust me, I'm an XT hoarder) 1) EMS emulation. Cards are difficult to find, at least cheap... (i hope this work on my xt-286, as a rare hybrid between AT & XT worlds) 2) LAN emulation. OH yes!. I want samba-share full RW …
