- This is an extensive "production test/diagnostic" for the
- Pertec/Icom Single and Double Density Disk Controller. The
- files 3712DIAG.ASM and 3812DIAG.ASM are "self documenting",
- with a "menu display" of test options at the first execution of
- either program. These programs were originaly written for the
- MITS Altair 8800b Computer, and therefor utilize the MITS
- console port address's of 10 and 11 hexadecimal. These
- address's may easily be modified by changing the console
- equates as required by you console I/O. In addition, the
- 3712DIAG.ASM file is compatible for testing the older Icom
- "Frugal Floppy" system.
-
- Primary differences between the FD3712 and FD3812 diagnostics
- are in "density select" options and diskette formating
- capabilities of the 3812DIAG.ASM file, which supports the IBM
- single density/single sided format, "1D" format, "2D" format,
- and "2D Extended (1024 bytes per sector, 8 sectors per track)
- format ("2D Extended" is hardware dependent on DMA transfer
- capability).
-
- This code was initially written by me about 3 years ago, when
- I first got into codeing for the 8080, and is therefor a bit
- "amateurish" in some areas...that "INIT" routine with all the
- "STA's" for example! But in any case, the code does work quite
- well for a first effort on my part...
