Well several of my replys were rejected by classicomp email system
so here they all are together... :^)

I don't have one, but the instruction set was listed
on the Internet once or twice, 0,input ... What I
don't have is the "Wireing" that graphic on the "cpu" side
that controlls operation, and there are part that change
with the instructions. Yes I would like a cardiac, any
donations? (will trade for C coded emulator :^)
[ will code for toys?? ] )



I went on to "design" the 8 bit machine described because
cardiac won't handle character data, only 3 digit numbers.

I also wanted to make use of the a whole 8 bits, and have
each instruction use only 8 bits (well some of them do read
the next byte via indirect of the PC) Also I think the flag
testing at for each instruction is um clever, what do you
think.

will repost instruction set if desired.

I really wanted some of you to look over the instruction
set and theory to see if I was obvously missing somthing.



Reply to Zane... Thanks for the pointer to the TOPS-10 emulator
I will see what I can do with it...
