I just wanted to say a big thank you to everyone who has responded to my original post. It's all been very helpful. My file (in raw Hex
) is now with the paper tape supplier, so we'll see how it goes.
And, yes, I'm doing this just to recreate a possible historical situation, where an MK14 user in 1978 may have got hold of an OP-80a and tried this out. Once I get this working on the MK14 I'll have a go with another retro computer – likely the KIM-1.
Thanks again.
