Not really, it is only an OR. Also as I said it works only for RAM. PROM adressing is all static. It could be added by grabbing a register value and macgyvering some cca somewhere... but you could also just write a program that adds ur immediate to a register value (takes only 1 instruction) and then laod from that adress (takes 2). So, combined 3.
Uhh, thats prolly what you meant.. yeah you can write a program doing that.
One could probably try do arrange a bus that similarly feeds a reg value to the program counter, in the current layout that would probably involve more than 1 sometimes "lost" instruction until it arrives...
But before you try that a quick glance at the bussing should very well tell ya that a reconstruction (=a new better CPU) is a far better idea...
Especially as the CCA used is by far not up to date in terms of speed or size, and the ram decoder is for bigger and laggier than it should be.
Fuck, if only I had the time too.
Some day, surely!
