HP200LX Palmtop PC with Adlib Soundcard plays Commander Keen 4 thru a PCMCIA Parallel port card...

The HP200LX is a Palmtop PC from the early 1990's. It&an IBM PC/XT compatible PC with CGA graphics (on a monochrome screen with 4 shades of grey), and this model is an original (unmodified) model with 2MB RAM. (640KB for MS-DOS and the remaining memory is the RAM drive for the "hard drive" as C:). It runs the original MS-DOS 5.0. The Palmtop has a PCMCIA parallel port card inserted in it&PCMCIA slot on the left and is connected to an OPL3LPT, which is an adlib-compatible OPL3 chip based adlib soundcard that works on parallel ports. This video is part of a set of 4 videos on my channel showing various games (demo versions) of Commander Keen 4, Leisure Suit Larry 3, Police Quest 2 and Kings Quest 4, all games that I played when I was a child ;) contact me for technical details if you want to replicate this setup.
