[cctalk] Re: IDT 49C402BG84 Pinout?

Ok, this is a full fledged mainframe CPU.. not really what I want todo first. That stuff tends to "explode" in sight of parts, needed power and space, I know that. On the other side I saw different controllers for PDP11/VAX stuff that used the 290x to control "hardware". That are microprogrammed computers w/o any system bus and macro-instructions. Even the controller of an DEC RX01 RX02 is build around two AM2901. (I'm a former east german from "behind the iron curtain" and I own something like a russian PDP11/23 clone, an "Elektronika E60" that was used from a east german company "Carl Zeiss Jena" which had an dependance in my hometown to steer an X-Ray Spectrometer. The russian dual 8" floppy drive has also 2 pcs. of K1084BC1 .. AM2901) My first idea is to build a digital clock with a single 2901 - only micro programmed. Ok, it's total nonsense.. but all what we do here is playing with some outdated stuff, so where this clock.. I hope that I could do this with an single 2901 RALU, that means I have to calculate twice for 8 Bits, like the ALU in a Z80... Later I could try to build something with the 49C402, AM29116 or WS59032 to save PCB space.. All that stuff is already in my stash of parts, besides many 2901,2903,2909,11,10 etc... Maybe I'm trying to get that PCB with the four AM29203 and AM2910 from GE to life first.
