Thank you, yes, working so far, I looked at a memory location and it seems to be holding the right value (according to a book I have) =D>

It didn't work initially but I worked out the "b" key was stuck on. Took it apart (easily done, key cap just pops off revealing the contacts), gave it a squirt with PCB cleaner and it sprung into life :D

Futurlec even still stocks most of the components.

Nice, any chance of ROM dumps? We have this emulated in MAME but the usual system monitor is only one ROM, whereas you have two. There's also a Mastermind ROM in MAME for this board which may be of interest to you.

Certainly Nigel, I'll have a look at the ROMs, especially the extra one. Mastermind ROM sounds interesting, I'll check it out too :D

I love that the "display drivers" are literally transistors driving extra current.

This is brilliant (although I feel he doesn't really appreciate it for what it is):
