If you want to take the eprom approach, don't worry about sending a 2716, I will have a tube of them here somewhere. Keep your blanks handy because, although I did the best I could on one pass through, there might still be one or two differences between 'my' final version and the printed dump.

The best way to check that is for another pair of fresh eyes - yours - to have a look through it. If you read my version of the code out of the eprom and into your PP28 and step through, altering any values which you think don't match a printout of the dump, you can then programme your edited version of the code into one of your blanks and make that the new 'master' copy.

It'll take me a few days to round up one of my 2716s and the programmer and computer needed to program it - I'll PM you when it's ready to go.
