Re: Orpheus II soundcard thread

Repairing a Dead Roland MT-32 Nice work! I especially like how you managed to fix the LCD display by swapping out those worn out flat cables with DuPont connectors. Those things are super useful for any kind of retro work. I sometimes use the longer ones to get digital audio from a CD-ROM drive and …

Repairing a Dead Roland MT-32 A user from the DOSReloaded forum sent me his dead Roland MT-32, arguably one of the most sought after and iconic synthesizers for playing vintage DOS games.

The M396F 386SX Homebrew Mainboard Marco Roth reverse engineered a broken M396F mainboard, powered by a 386SX CPU. This tiny Baby AT sized mainboard comes with six 16 bit ISA slots, four 30 pin SIMM sockets, a 40 MHz AMD branded 80386SX CPU and is a fancy purple color! Does it work? Let’s throw some …

Re: Can this Gravis Ultrasound PnP be repaired?

What's very interesting now is: they are indeed similarily oriented in those two pictures above, BUT: on the card in front of me, it is turned by 180 degrees (apparently as 640K!enough is also seeing it on his side). And what's even more fun: a while ago I found that my ROM isn't showing up in …
