Greetings,
I've recently released a new version of my Heathkit H-89 emulator. The H-89 is a Z80 based 8-bit computer from the early 80's. Heathkit was the manufacturer along with their H-8 and H-100 series computers. The system came in kit form or preassembled. Originally the computer ran Heathkit's own disk operating system (which is in the public domain now) called HDOS. By the way, HDOS was written by Gordon Letwin who, after Heathkit, went on to Microsoft as one of the original 12 employees. Eventually several versions of CP/M were released for this computer too.
The H-89 emulator is part of my H8D Utility program. This utility was made to manage the approximately 400 disk images for the Heathkit 8-bit computers on my web site. With it you can catalog the contents of all the disk images, send disk images to a real H-8 or H-89 over a serial port link, receive disk images from a real H-8 or H-89, send and receive disk images to/from an SVD (Semi-Virtual Disk) that is connected to a real H-8 or H-89 and load and boot any of the disk images using the built-in emulator (if you don't have a real system).
To my knowledge, this is the first publicly released emulator for the Heathkit H-89 computer.
The emulator boots to the following operating systems:
HDOS 1.6, HDOS 2.0 and HDOS 3.0
CP/M 2.2.02, 2.2.03 and 2.2.04
My H8D Utility and emulator will only run on XP, Vista or Windows 7 systems. It is written in C# and uses the XNA runtime to render the terminal font and graphics. You need the .NET Framework V3.5 or later and the XNA runtime installed.
All of the following links are hosted from my own web site.
