AT&T 6300 Keyboard Controller

by tarsi＠binhost.com

Greetings, all! System in Question: AT&T 6300 I have two of these systems and was going through them, taking the best parts of the one and putting them in the other to build out a good machine. I happened upon a difference between the two that I can't figure out what I've stumbled upon. The keyboard controller for the 6300 is either an 8041 or 8741 chip, as defined by the service manual. The one machine has an 8041A chip, so that's normal. The other machine doesn't have a chip at all. Instead, it has a piggyback card in that slot where the IC is supposed to be. The piggyback card has a chip on it that LOOKS to be a 88414 chip. I'll write below all the relevant numbers on the card. There is a wire that goes from the board around to the topside of the logic board as well. Not sure where it connects, I haven't pulled the logic board completely up yet. Anyone have an idea of what this might be and if so, documentation and/or description of benefits? Thanks for your help! Tarsi 210 List of Relevant Numbers: - On the main chip, it has 88414 plus a adhesive tag that someone had written on it "PDBD". - The board itself is stamped: 491230 Z MI293 NA 6/84 (the last the date, I presume) Also on the board is: MI293 COD.49199P-E-E4 - Yet another chip has the number: TMS7000NL-2 -- ---------------------------------------------- Homepage: http://tarsi.binhost.com binHOST.com: http://www.binhost.com Forever Beyond: http://www.foreverbeyond.org ----------------------------------------------

CPU design at the gate level

I was burned a few times back when. At least three vendors have most of the TTL line, JDR being one. I might add that in '73 I did a TTL design, finding many of the chips that were in the books was a task as many were unobtainium. Allison

One-off vs. One-of (was Re: CPU design at the gate level)

Her main fun... http://www.hampsterdance2.com from her Win9x box and Rogue and xlockmore on FreeBSD. I'm hoping for more interest in the latter. I'm seeing no signs of interest in how the stuff works beyond her help with screwing the stuff together. She must have picked up the field service genes. Bill

Thick Ethernet/Sun networking problems

Quite ingenious. That uses a cheat that's built in to Intel print servers. As Iggy says, the print server listens to all the packets that go past, and infers its IP address from the address contained in the first ICMP packet it sees which contains its own MAC address. It's not the normal way of doing it at all, and it's not reverse-ARP, which Lawrence said the printer used. It's worth a try, though, since it would only take a few moments to test. And the Calcomp web page does say "make an entry in the ARP table". -- Pete Peter Turnbull Network Manager University of York
