What is PicoGUS?

PicoGUS can emulate Gravis UltraSound, AdLib (OPL2), CMS/Game Blaster and Tandy 3-Voice, and supports MIDI output with MPU-401 intelligent mode emulation. It comes in two versions: the original ISA card, and the Femto Edition that can plug into a Hand386/Book8088 or ISA adapter. This listing is for the Femto Edition, complete with ISA adapter.

Please note: PicoGUS Femto Edition does not come with a Raspberry Pi Pico. It must be purchased separately and plugged into the headers on the PicoGUS.

How does the Femto Edition differ from the regular PicoGUS?

First of all, the Femto Edition plugs right into the expansion connector of the Hand386 or Book8088. If you have one, PicoGUS Femto Edition will greatly level up the sound abilities of your new little retro device!

But I didn't want to leave out regular retro PCs with ISA slots, which is why I also include an ISA adapter that lets you plug PicoGUS into any normal ISA slot.

Another thing is that the Pico hangs outside of the PC when in the ISA adapter. That means that any upcoming WiFi support on PicoGUS will benefit from better reception.

Please see the PicoGUS GitHub project and compatibility list for more information on PicoGUS and what computer systems, games, and demoscene productions it is compatible with.

What do you get?

• A green PicoGUS Femto Edition board, fully assembled with headers to plug a Raspberry Pi Pico into.
• A black ENIG ISA adapter with configuration jumpers, that lets you use your PicoGUS Femto Edition in a normal ISA slot.
• A 3D-printed card bracket, assembled to the ISA adapter board.

I want MIDI output!

The Femto Edition of PicoGUS uses a 2.5mm "Type A" TRS MIDI jack, and I can't find a source to buy them in large (but not too large quantities) at a discount. If you want one I use the cable that Quilter Labs sells - they're $5 with free shipping which is a good deal.
