It is not as useful for actual use as the current ones, BUT, it is
historically significant, and is handy whenever you are writing software
for others and public to use, since it has many problems that later ones
solved.
You'll find that that chip will have difficulty reading the first sector
on TRS80 disks, Cromemco disk, and maybe even SOME Kaypro disks.
OTOH, if it works with that chip, then it will probably work with
everything!
When writing XenoCopy, I started off by testing everything on real IBM PC.
But, after giving a copy to John Dvorak, and having it not work on his
after-market POS, I started testing on every BIOS and every FDC that I
could.

Correct it was the early version as in 765, not 765A, the big fix was
shorter
VFO sync time.
I have some of those not much use for them as I also have the 765A part.
