That was 64bits of internal storage and that is different from a 64bit
parallel CPU. Also 613khz is slow.
There are otehr 64bit cpus, some are in games and other embedded systems.
However the number of systems for general purpose computing using 64 bit
cpus are however few.

Not that slow. Depends what you do with the clock. Remember that a
Motorola 6809 running at .8 Mhz (800 Khz) could always beat an Intel
8088 running at 4.77 Mhz by at least 25% and usually 50% in tests I
used.

I'll have to do some research to back that number up. I picked it up on
a web page and never actually double checked it. I've seen many
allusions to the slow clock speed of the HP85 and I'm pretty sure it's
below the 1 MHz.

very much like it.
