ACT insights



#2

Evenin' (o;

Are besides the documentation in the service manuals more information available about the insights of the ACT and its timing to do his work?

Are the ROM contents somewhere available of the HP-21/22/67/97 available?


Reason for asking: Doing things in FPGA ;-)

So if I understand the few documentations available for ACT, it only executes the microcode stored in the several ROMs it is connected to?

So it is just a simple BCD optimized CPU.
