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.
