Major difference between 1LF2 and 1LK7 is the addional opcode Are you sure? I don't remember if the 1LF2 even had a PC=A instruction. Even if it didn't, it still could have supported RPL, albeit with a big performance penalty : Code: A=DAT0 A instead of just Code: A=DAT0 A If the 1LF2 had a PC=A instruction, then one could do Code: A=DAT0 A which is still very slow, but saves one instruction Jonathan Aeternitas modo est.
