My job was to write the software in 6502 assembly. Unfortunately, there wasn't an assembler and the KIM-1 just had a hex keypad and small display. So, it meant writing the code by hand, hand assembling and typing it in. The code looked like this... Running code in your head is perhaps the most crucial of all skills for a software developer.

In 1985 I was learning Pascal on a PDP-11.

He should of course have been using a proper microprocessor, i.e. a Z80.
I was writing windowed graphics software in an advanced form of BASIC with a specialist keyboard that allowed coding faster than I've seen achieved since in 1985

It's odd that he'd still be using a Kim-1 in '85, they were around in the mid-70s and he probably could have worked faster if he'd used an Apple II or any of the early 80s micros.
In '85 I was using a 6502 assembler but I wasn't forced to convert opcodes into hex. Although I do still remember some of them like A9 is LDA# immediate (literal value), 8d is STA absolute addr
By far the biggest kick I got out of it was exploiting the 6502 bugs.
