The weeCee is perhaps the smallest MSDOS gaming PC ever made that doesn’t use emulation.

It is based around an ICOP Vortex86 CPU module, which is a pentium-class x86-compatible embedded system-on-module that is intended for industrial control. However the module also works great for DOS gaming, as it includes a highly-compatible VGA graphics chip.

To this I also added a Soundblaster Pro-compatible sound chip from Crystal Semiconductor, which is still available new-old-stock from utsource, and a gameport-compatible connector for using joysticks and gamepads.

It can also support internal waveblaster MIDI expansions such as the Dreamblaster S2, or external MIDI sound modules like the MT32 and Sound Canvas.

It also includes network support for multiplayer games, as well as a USB connector for mass storage devices.

Enclosure will require a Hammond 1457J1201 case, as well as the end-plates gerbers included in the zip file below.

HIDman is an open source device to allow the use of modern USB keyboards and mice on legacy PCs.

Peripherals that support legacy PCs are becoming hard to find, especially for the very first PCs. This project aims to provide a simple cheap solution that will cover everything from the original IBM 5150 PC all the way up to modern computers that have PS/2 ports.

You will also need to order the Front enclosure plate : https://www.pcbway.com/project/shareproject/Front_enclosure_plate_for_HIDman_0aec2ae9.html

And the Rear enclosure plate : https://www.pcbway.com/project/shareproject/Rear_Enclosure_for_HIDman_c0ff0b8a.html

Grab the rest of the case from here : https://lincolnbinns.com/e-case-a-black-40mm.html

Don’t forget 8x screws : https://lincolnbinns.com/e-case-screws.html (I suggest the thread former ones)

You can find ps/2 cables, serial cables, etc from ebay or aliexpress.

Teensy-based External Storage

Programming adapter to program M4ROM_TANDY and M4ROM_27256 .

Solid electrical contact with the center pins is made the fact that the receptacle holes in the center of the M4ROM boards are slightly closer together than the pins on the programming adapter.

One pair of the 2.0mm pitch pins on top needs to be cut from a 2x7 header to form the polarity key.

Don’t try to use flush cutters for that, the plastic will shatter and you’ll be left with loose/bare pins.

A hobby knife on a cutting board works better, with a paper towel laid over the header to keep the small part from flying away.
