I'm a DOS game enthusiast myself, grew up with IBM PS/2 and still fancy many DOS games over newer releases. Although Dosbox is awesome I prefer genuine hardware whenever I can. I have a big collection of AT hardware in various phases of decay, and a big problem with old hardware has been its reliability. Especially those cheap chinese PSU's that were in almost every 2/3/486 are prone to blow up and contain usually no proper overvoltage/short circuit protection to save components from frying.
I and my friend who is an electronics engineer came up with an idea to remedy a part of the equation while still retaining the original functionality of old hardware. The parts that can most easily be replaced with new more reliable hardware are hard disks and psu's.
We are in the stages of putting together a pcb adapter board that allows one to use good quality ATX power supplies with soft/hard off with AT motherboards. The board is quite cheap to produce and doesn't require complex components (like IC's) for functioning. The benefits would be the higher load handling capability of new ATX PSU's and also better tolerances on voltages (and the option to use soft/hard off with a jumper).
How many of you would be initially interested in buying such board? We are not making profit with this, and the PCB design would be released as GPL.
Our next project is an IDE adapter that allows replacing old unreliable hdd's with an USB memory stick or other usb mass storage.
