Thanks - that would be very useful, if you have time
and suitable hardware.? I read the pages at
geekdot.com a couple of
weeks ago, but I'd not seen the MAME data.? I did find a manual about the ROM on
Bitsavers recently, so with that ans
the MAME info I can probably work out what some of those settings should be if
necessary.? Sadly nothing I've found says
anything about the internal LED display, but my suspicion is that the error is to do with
bad RAM.
