The SC/MP is finally alive!

[river]

Hi,

Found the problem with the SC/MP. I don't have the SC/MP programming
manual but have figured out there was a difference of opinion between me
and TASM on a few instructions. I now understand all the SC/MP instructions
and TASM's expectations.

Anyway, it's advanced from the prototype breadboard stage and it's now 
a permanent system - all soldered and complete.

For those that are interested, it's a SC/MP II (ISPA/600D) running at 2.048Mhz.
It's got 2 x 4K (2732) EPROM, 2 x 2K (6116) RAM, 1 x 8251 USART and
1 x 8255 PPI. I've got the comms and PPI working a treat and now I've got to 
embark on the fun task of creating a debug/monitor for it.

Does anyone else here build old stuff like this? Or do you build your own debug
and monitor software? Any experimenters/builders here?
