Hi!
I have been mostly lurking here, but I have been designing a DRAM board for the
HP1000 A-Series, using a more
modern 72-pin SIMM. The A400 can adress 32Mb of parity ram so I use 17 bits on
a 64Mb SIMM. I have taken
inspiration from the original HP12103X boards and tried to keep away from
es
1980's Fanuc tape reader PECs are fitted with two families of connector I am
unfamiliar with : one is used for power and the other for signal connections

Yes, 1620 addition and subtraction do stop if the addend is shorter than the
augend and there's no further carry.
There was no pre-defined limit to the length of integer operands. If you had
the memory to do it, you could add two 10,000-digit operands. Floating-point
numbers were limited to 99

I did most of my Atari 520 programming using TDI Modula-2 and Prospero
FORTRAN 77.

Funny when the 8 and 16 bit micros hit the market, Algol seemed to vanish
off the face of the earth. Was 64KB too small a address space?
It's likely to be the same reasons

Yes, but punch cards did not have to worry about magnets. 😊
