  5) Multitech MPF-1B or MPF-1P "Micro
Professor". Why? Because it folds up
    like a book - I know of no other computer like that. 
Not really. It's in a book-shaped case, but the signle-board computer 
takes up one half, the other half is empty. Option boards (there's a 
printer, EPROM programmer, Speech synthesiser, I/O option, etc) fit in 
the other half, but then you can't close up the case....

  Items not necessarily in that order of course. I
can probably fix a SYM1 and
 I would actually prefer a SYM - ISTR they didn't use mask programmed 6530
 (6532?) chips, unlike the MOS KIM. The AIM65 is, IMHO, pretty neat. I like 
Must be the 6530. The 6532 is a RIOT (RAM, I/O, Timer) and AFAIK has no 
mask-programming options. 
Hi
 There are a number of similar things between the 6530 and 6532, other
than the ROM in the 6530. Still, you can't just replace all 6530's
with a EPROM and a 6532 because some of the level inversions and
address selects are mask selected in the 6530. I've not looked
into the one on the kim but for those that have blown 6530's,
one may still be able to make a board using a 6532/EPROM and a
little glue logic.
 I have a Gottlieb pinball machine that this is not as easy to do
because of signal inversions.

  the 6502 - what can you expect from someone who
grew up using BBC Micros? :)
 At least the 6502 is a bit more logical than, say, the x86 >shudder<. 
Err, I'm a 6809er....
