Default Re: Tesla MH74S571 programming.

Hi all - reading this thread with interest. I have two original MK14s. One is the earliest (Rev 0) with the membrane keyboard and a later one with the calculator click plates - I took that off and attached a bodged keyboard from an old calculator (kicking myself now - it was a Nixie tube calculator. Quite rare! Never mind). But - I have a problem with a set of 74s571 PROMs. I need (if possible) two sets blown. One with the early monitor, one with the later monitor. I have four new (old stock) dm74s571n PROMs. Would anyone be able to help? Very happy to pay, contribute to charity or whatever!

PS - my early MK14 had problems with a very dim display when I first built it at the tender age of 11 or 12 when it first came out. We ended up driving it up to 9 Kings Parade in Cambridge (thanks Dad!) where a rather tall and bearded gentleman called Clive (yes, that one) sat there with soldering iron and Fluke multimeter and sorted it out for me. Very happy memories!
