If you had a H-100 in the 1980's, you might remember these two graphics. Click for full-size:
Heathkit H-100 / Zenith Z-100 programs
| DeSmet C | Functions and programs written using the DeSmet C compiler. |
| GWBASIC | Programs written in Microsoft GWBASIC |
| File Allocation Table information | The web page for my Borland C++ program for reading absolute disk sectors has a data table summarizing FAT types for various H-100 disk formats, and a partial debug listing of the boot loader for a 96 TPI disk, with its data fields labeled. |
A site search will turn up additional references to the H-100 throughout the site in text documents and project notes.
I have a few H-100 related hardware items available for sale on the prospective eBay auctions page.
