I tried to sell mine, complete with docs for $15 at a Hamfest nearly 10
years ago and got no nibbles. This was before Linux hit it big.

That's nice to know. I have a few '010s (the VAX-BI COMBOARD used them).
I didn't assume it was a drop-in replacement due to the MOVEcc instruction
being now priv'ed (AmigaDOS 1.1 will croak if you upgrade the CPU without
running a TRAP patch (available in the olden days). The calc program was
the way to test the patch. If you Guru'ed, you weren't patched.

As I said, mine has Uniplus (w/boxed docs and media).

We used ours strictly for text-based development on the console and a couple
of TTY ports. Still, it wasn't a fast compiler, I did notice, even in 1987
when I was using it.

Fun. What kind of disc? SCSI? Am I right in remembering that the 7500
has SASI?

I'm sure by the time it was produced, the world had moved on.
