The IBM Music Feature Card and Yamaha FB-01
This has got to be one of the most obscure pieces of hardware I have covered so far. A sound card for the IBM PC, released in 1987. And by none other than Big Blue themselves! I am talking about … Continue reading
The DreamBlaster S2P: General MIDI from a parallel port
In the interest of catching up, here is the second blog that is long overdue. I want to talk about the DreamBlaster S2P from Serdaco. I received mine over a year ago, and it actually was an early prototype. The … Continue reading

Putting the things together, part 2: MIDI and other problems
Remember a few months ago, when I explained my approach to playing VGM files? Well, VGM files are remarkably similar to Standard MIDI files. In a way, MIDI files are also just time-stamped captures of data sent to a sound … Continue reading

Commander Keen 4: now in 16-colour composite CGA!
Perhaps you have already heard it through the grapevine, but just to be sure, I’d like to mention that VileR (of 8088 MPH fame)has patched the Keen 4 code and redid all the graphics to make the most of the … Continue reading
