Processor Instruction Sets

I guess the ACT's from these different series were never meant to be interchanged and it was probably easier to implement the op-codes in this way due to internal chip design.

This list may help, but cannot guarantee 110% ;-)

Code:


 :
Op Code                 HP-01     Classic   Woodstock (All OCTAL Codes)
data -> c                N/A       1370      0070
data register 0 -> c     N/A       N/A       0070

Just wondering as the same op code can't be used for both instructions on the Woodstock processor which one is correct.. ? (I think it is the former..)
