Can anyone help with identifying the following (used in some sort of 8"
disk data-logger/controller):
Intel P2101A-4 22-pin (.4 or .5 in. wide)
Intel D3624A 24-pin (.6 in wide) (house numbered ROM's???)
Intel D3002 28-pin (.6 in wide)
? 9406 PC 24-pin (.5? in wide) large "F" on package (Fairchild???)
Any comments appreciated!

Dunno, but probably also in old databook.

I believe it is a part from the 1970's. There were various TTL IC's having part numbers which began with 9 or 9N. Larry Lippman @ Recognition Research Corp. "Have you hugged your cat today?"

Amazing, a chance to catch Larry out on something! :-) It's a *two*-bit microprocessor slice. Intel decided that having more buses on a small package was worth doubling the number of chips for a given system. The market generally disagreed and those chips weren't too successful. -- Imagine life with OS/360 the standard | Henry Spencer at U of Toronto Zoology operating system.

My favorite was the Motorola 1-bit cpu chip. Don't remember too many details except an 8085 was cheaper. They did have an app note where it controled traffic signals. Hmm. Wonder how it did that...

These are some kind of SSI/MSI logic like the 7400 family. I'm pretty sure they're TTL. ***************************************************************** * Dana H.

No problem, you could extend the opcodes with an address field and use a multiplexer to select an input channel. The finest thing was that it didn't have a branch instruction. You could store the result of an operation into a flag and it would continue reading instructions (but not execute them) until a clear_flag instruction was found. -- Michael van Elst UUCP: universe!local-cluster!milky-way!sol!earth!uunet!unido!mpirbn!p554mve Internet: p554mve@mpirbn.mpifr-bonn.mpg.de "A potential Snark may lurk in every tree."

They did have an app note where >it controled traffic signals. Hmm. Wonder how it did that... B-). From what I understand that 1-bit cpu chip was intended for use in highly parallel variable word length computers that would use thousands of them together (like the Massively Parallel Processor which had an array of 128 by 128 single bit processors. They used their own custom chip that had 8 1-bit processors in it, not the motorola chip.) If you ever looked at the chip's instructions, you will notice that it could be disabled by setting a bit causing it to ignore the instruction stream; just what you need when you are sending the same instruction stream to thousands of processors at the same time and need to "branch" around part of the code in SOME of those processors. Whoever wrote that app note came up with a totally unreasonable application for this chip (that could be much better done with other parts), but it did illustrate how it could be used without necesitating a multi-million dollar project to build a "supercomputer" be explained in an app note.
