Good suggestion. That leaves, if I'm not mistaken, only the Serial ULA. ;-)

'tis a shame these bits and pieces (along with PALs and other such 
custom logic) have so little known about them. But, then, as the years 
go by I wonder how little sourcecode for anything actually still remains 
- all those archived ROMs. And if what does remain is even readable?


Best wishes,

Rick.
