Really? I find it hard to imagine that Wirth would use Fortran for a
compiler. Never mind his background in structured languages --
writing a compiler in Fortran is just much harder. Not as hard as
writing o

But then, much later, . . .
Microsoft/IBM PC Pascal was written by Bob Wallace.
I have no idea WHO, but Microsoft/IBM PC FORTRAN was written in Microsoft
Pascal. There was an odd little warning not to use any 6

I've seen a fair amount of furniture like in the following picture:

It looks well-made, industrial, and vintage (sort of). Anyone know who makes
such things?
Did IBM have a go-to desk manufacturer

My question is if TKB overlays also have these extra instructions?

Someone was kind enough to mail me the masked ROM out of his HP 9895
floppy drive. I've read it and mailed it back. It's an MK36000 series
24-pin 8KB masked ROM, with the same pinout as the Motorola MC68764
EPROM, so reading it with an EPROM programmer set for the Motorola
part should work fine. In
