From: "Peter "Firefly" Lund" on 22 Dec 2006 03:49 Does anybody know where I can find microcode listings for old Data General, IBM S/360, or Norsk Data machines? Microcode for the T-11 ("Tiny") PDP-11 microcontroller would also be greatly appreciated. -Peter

Yes, please! :) (I'm more interested in Norsk Data and T-11 but this looks like a good find, too) -Peter

The T11 was the micro used on the Falcon embedded qbus board right ? - spent a couple of years writing macro 11 for that board and may still have the ug somewhere, though not sure if it includes microcode listings. bitsavers.org may be a good place to start for any of the older mini info. So what's so interesting about the T11 ?. A more modern embedded equivalent would be the Texas msp430. The msp is a risc design under the skin, but the registers, instruction set and addressing modes look like it's been cribbed almost direct from the pdp architectural model. Dejavu indeed... Chris |
