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...
