Les bird sent along the following update from the SEBHC Google group regarding his Heathkit H89 Emulator (I recommend checking it out just to get to try out some classic CP/M and HDOS games. Screenshots below!):
Yet another update to my H8D Utility is up on my web site. V1.47 which includes a much improved H19 simulation for the integrated H89 emulator. Timing is improved as well so it should run quite close (not exact) to an actual 2MHz H89 when the 2MHz box is checked. I now render the output to a DirectX surface (XNA run-time download required) which looks much better, runs much faster, and now can be toggled to a full screen window. The games (both CP/M and HDOS versions) run pretty good - Munchkin, YWing2 and Grav were all tested and working. Just remember when playing the games that you should use the numeric keypad and you should have the NumLock key down.
Direct download can be found here:
XNA run-time download here (via my web site) - download and install this before running the emulator:
Bootable disk images for CP/M and HDOS 2 here:
I've received some positive feedback about the emulator as well as some suggestions. Thanks!
XNA for Windows should be available to anyone. Just download the run-time from my web site (linked in Bill's post above) and install it on your XP, Vista or Win7 system. The emulator is written for the Windows platform, not for the Xbox 360. Just think of XNA as DirectX for managed languages like C#.
