I am not an expert, but are all petaflops the same? might there be some
applications fo which this is relatively better than the nominally equivalent
petaflops of nvidia? as in how intermediate results are shared between
calculation units, this is likely to be more cross connected so values
And the 1620 was a 2 decimal digit exponent with a 2 to 98 digit mantissa.
IIRC, you could do math on two numbers with different length mantissas. You
could watch a division with a long mantissa crank through.

CP/M (Originally Control Program/Monitor later Control Program for

I came across an article that said CP/M came out in April 1974. I remember
using this OS in the microcomputer world in the late 70’s; early 80’s. It
came from PL/M, (Programming Language for Microcomputers) later renamed
CP/M(Control Program for Microcomputers). I’m not sure what its legacy is

Auction is at $435K now (past the end time) with multiple active
bidders extending it.
And since nobody else seems to, allow me to recall:
- MINC BASIC, with all its extensions for I/O and real time events.
- MUBAS, the multi-user basic for RT-11.

Quick Basic and I seem to recall all or most of M$ Quick compilers were

Hardly. The Model 100 basic had a ton of features including modem
support, date/time, and so forth. Lots of programs and utilities were
written in the BASIC, and games such as Heartbreaker worked perfectly.
