My original idea was to attempt to build the modified version of the
programmer featured in the archive, but I could not get the software to work,
I didn't fancy typing in all the source code so I gave up the idea, and decided
to have a go at the BEEBUG one.
I have an addemdum sheet showing the position of track cuts to be 1 row
to the left. I am unsure if there are any more modifications needed, apart
from the obvious links that are missing from the circuit layout.
I'm going to go to CPC in Preston tomorrow and get a replacement TL497,
its only a couple of quid so worth a try at least.

I've got a couple of tweaks to add from other people on this list, but
overall, it works. I was going to add a switch to program both halves of a
27256s some time, so they can be used in ROM boards that support bank
switching (I had trouble getting 27128s last time I tried).
