Looks like the OP's question has been addressed and this thread has taken a most unusual hijack grin
Man, night shift blows grin
Back in 82 I got my 1st so called "laptop". It was an IBM but I don't recall the model. It had a huge 7" screen (monochrome) and 2ea 8" floppy drives. I think it had a whopping 64k of memory and no HDD. I'd load my program disc into drive A and my data disc in drive B to work it. Danged thing weighed about 30lbs.... IIRC it was as big as three cinder blocks. I used it to program the new Harris D1201 PABX. The optional ARS/LCR module had a huge cassette tape that stored it's program & data. I'd either use a TTY terminal or plop a Procomm Plus communication floppy into the IBM to program it. Give it a command and watch the tape run and search for the sector, neat stuff....

Those punch card readers were ahead of my time as they were phaseing them out. But we still had to learn 'em in tech school.

Anyways, I haven't seen solid core plug wires in a long time, at least I don't recall so grin
