Hi Sirius,

I'm fairly open to my options as to getting these programmed. Ideally I'd like to do it myself, but if someone were to knock on my door and offer me a pair of ready-programmed PROMs I wouldn't turn them down.

I don't anticipate programming any further PROMS after the pair for my System 1, so a temporary, Heath-Robinson jury-rig would do the job fine. As it happens, a (DM74S571) PROM and EPROM programmer was manufactured for the Acorn System range, and a circuit diagram exists (https://www.4corn.co.uk/archive/diag...Programmer.jpg) but I don't know of any surviving software to go with it. I've only just gotten my System 1 working, and I'm not up to writing my own programming software (in assembly) quite yet! I'd probably be more likely to try coming up with something standalone, or lash something up to either a BBC micro or an arduino instead.
