Have used it on 7KB RAM :) But to be fair the interpreter was in ROM, no idea how big that was.

- teddyh 6y agoROM was usually very slow, so all ROM content was usually copied to RAM before execution. RAM size was therefore still an issue.
- usr1106 6y agoI am pretty sure the PET-2001 didn't do that. 8 KB was all it had, about 1 KB was used by the operating system and 7 KB where available for programming. Actually something you would call byte code today, every basic command was 1 Byte. Just don't use labels with 4 or 5 characters, that wastes a lot of space! The first models came even with 4 KB RAM / 3 KB usable. Have never seen one of those, though.
