If any list members are looking for Wang terminals, I have several of the 2236 models that I used on an 2200MVP system for many years. In addition, I believe I still have many 5 Mb removable platters for the Winchester drives used on the 2200. Please direct any interest off list to WB6BLV at inreach.com

If I were mean and fought with Rob I could probably get lower prices...but he treats me good. ; ) They charge the same amount for the Altair 1MCS memory chips, 2101 or 2102s, I forget...

They are relatively rare, but they aren't even close to being _THAT_ rare. I'm talking about his asking price. I bought one three years ago from a fellow collector of CPU chips for _$20_ that had some markings worn off and was scratched. I opened it up to photograph the die (a hobby of mine): http://diephotos.blogspot.com/ I've haven't even seen rare versions of white ceramic 4004 ICs in perfect condition go for anything close to his asking price. I've seen a complete, mint condition MCS-4 (4004) chip _SET_ go for something close to $1K.

AW: cctalk Digest, Vol 64, Issue 52; any idea what this schematic is?

by gerhard.kreuzer＠liftoff.at

Hi, Ist definitely a RS422 interface, and ist the 4-wire version. You have two lines for sending data (Tx+, Tx-) and two lines for receiving serial data (Rx+, Rx-). Its a +-5V differentially signalling technique to get high speed on long lines and archive better noise immunity.

They're not quite the same thing, though a D-type flip-flop is a kind of latch. There are other types of flip-flops, such as T, RS, and JK types, usually edge-triggered. In a D-type, the active clock edge causes the output to change to match the input, and having changed, it stays that way, even if the input changes while the clock is still at the same level. The transparent latches that are commonly just referred to as "latches" (eg in data books, where you'll find some devices referred to as latches and others as flip-flops to distinguish them) are level-sensitive, and the output tracks the input (including changes) while the clock is at its active level. -- Pete Peter Turnbull Network Manager University of York ------------------------------ Message: 2 Date: Sat, 20 Dec 2008 18:10:04 +0000 (GMT) From: ard at p850ug1.demon.co.uk (Tony Duell) Subject: Re: PDP-8 on FPGA project & where is Hans Pufal?

As I understand the terms, a D-type flip-flop is edge-triggered, a latch (or more exactly a transparent latch) is level-operated. What I eman is that for a D-type flip-flop, the output (Q) is set equal to the input (D) a short time after the rising edge (say), of the clock signal. At all othter times Q does not change state, no matter what D does. So if clock is held high all the time, or held low all the time, Q will never change. But with a transparent latch, then if the clock (sometimes called the enable input) is in one sate (say high). then the output (Q) tracks the input (D). When the clock input goes low, then Q is held in whatever state it was in as the clock input went low. A simple example of the differnce. If you take a D-type flip-flop and connect the output to a NOT gate and the output of that back to the D input, then you get a divide-by-2-circuit. Feed in a regular clock at one frequency and the Q output will toggle at half that frequency. But if you do the same thing with a transparent latch, you get something that oscillates at a frequency determined by the propagation delays when the clock is high. In other words the output is somewhat unpredicatable, it's certainly not a square wave at half the frequency of the clock signal. -tony ------------------------------ Message: 3 Date: Sat, 20 Dec 2008 18:12:55 +0000 (GMT) From: ard at p850ug1.demon.co.uk (Tony Duell) Subject: Re: Timekeeping (was Re: Sherwood Micro CPU/100) To: cctalk at classiccmp.org Message-ID: <m1LE6Jt-000J12C at p850ug1> Content-Type: text/plain > Hi > You should also consider building a free pendulum clock reference.

The "Lisa-Mac Interface Card" legend at the top certainly suggests that it's a schematic for the card from the story. The circuit appears to be what one would need to add a Mac-compatible serial port to _some_ machine. -ethan ------------------------------ Message: 18 Date: Sat, 20 Dec 2008 09:43:24 -0800 From: John Robertson <jrr at flippers.com> Subject: Re: Rockwell PPS-4 info (was 8008 v. 4004...)

I have just finished a project with a PIC32 (MIPS32 core) working as a voice codec and talking to a linux PC over the USB buss. We got it up to 310 kBytes/s and not dropping a single package during hours of running. The communication on the PIC side is solved by constantly polling the USB bus to catch every event. We had problems with package dropped every ten seconds or so but we traced it back to a iproute cache flush that the kernel was doing. The USB bus is fast but with standard hardware it isn't hard to get the speed up. If you have problem with overruns, check if the PC is doing some periodic maintainancy or there are any other devices using the bus. Sorry for being a bit OT but just to add a bit of nostalgia to my post, my next hobby project will be a transputer link to USB interface. :-) /Gvran ------------------------------ Message: 21 Date: Sat, 20 Dec 2008 23:15:15 -0500 From: "Jim Temple" <jetemp at insightbb.com> Subject: FDOS for Fluke 1720A To: <cctech at classiccmp.org> Message-ID: <000301c96322$ba111790$2e3346b0$@com> Content-Type: text/plain; charset="us-ascii" Hello, Saw your post and thought I would ask about the software and manuals for the Fluke 1722A controller.

Not sure about the date, but that's only two-ish years before I seem to recall seeing an article about the Mac in "Byte" (1983). > ...and the layout of the PCB suggests an Apple II card... I completely disagree. The location of the power and ground pins on the schematic are where the Apple II has the address and data buses (plus +12V, on the wrong pin for the schematic). Additionally, the signal names /VMA, /VPA, and E are usual names for MC68000 buses (or perhaps the 6809), not the 6502. Plus, suggestively, but not conclusively, the card form factor doesn't look to me to be something for the Apple II (the card is too tall compared to the width the fingers are drawn at). I'm reasonably certain that A) it's not an Apple II card, and B) it's a card for some 50-pin-bus 68000 machine. It might as well be the Lisa as anything else, but that could be confirmed by cross referencing the listed bus pins with Lisa documentation. -ethan ------------------------------ Message: 23 Date: Sat, 20 Dec 2008 23:16:11 -0800 From: Lyle Bickley <lbickley at bickleywest.com> Subject: Re: Engelbart's mouse / 40th anniversary To: "General Discussion: On-Topic Posts Only" <cctech at classiccmp.org>, "Marcin Wichary" <mwichary at gmail.com> Message-ID: <200812202316.11632.lbickley at bickleywest.com> Content-Type: text/plain; charset="iso-8859-1" Marcin, On Sunday 14 December 2008, Marcin Wichary wrote: > Here are my photos from the event, for those interested: > http://flickriver.com/photos/mwichary/sets/72157610918709769/ > > (48 photos in total.

I'm not sure what the mystery is. It fits a Lisa, and was used to download software to the early prototypes of the Macintosh. http://www.digibarn.com/collections/diagrams/early-mac-interfaces/index.html The earliest Lisa prototypes had 50-pin edge connectors for the I/O expansion cards. Sometime between 7/81 and 2/82 the Lisa got the pinch- fit, 56-pin edge connector for I/O expansion cards that it eventually shipped with. The collection of diagrams at DigiBarn (from which the flickr image was nicked) shows this evolution pretty clearly. ok bear End of cctalk Digest, Vol 64, Issue 52 **************************************

oregon software tape

by aek＠bitsavers.org

> The seller sounds like he would care too He doesn't.. I've emailed him several times with questions about specific items or if he has the other bits of things that he listed, and he has never had the courtesy to reply. He does let me know when I've waited too long in his option to pay him, however (I try to group lots together to save on shipping). I have identified the buyer of the other tape.

Turbo Pascal evaluation

by dgriffi＠cs.csubak.edu

Recently Al Kossow purchased from me an evaluation copy of Turbo Pascal which was previously evaluated by science fiction author Jerry Pournelle for his columnin Byte Magazine. With Al's permission, I have reproduced the text of the letter that came with that copy. ---BEGIN QUOTE--- Borland International 4807 Scots Valley Drive Scots Valley, California 95066 (408) 438-5400 Telex: 172373 Mr. Jerry Pournelle, November 14, 1983 Science Fact and Fiction (address censored) Dear Sir, Thank you for your interest in our company and especially in our new product, Turbo Pascal. I have enclosed the following versions of Turbo Pascal: 1. CP/M 80 on 8-inch SSSD disk for Z80 based systems. 2. CP/M 85 on 8-inch SSSD disk and 5-1/4 inch IBM PC. 3. MS DOS 1.1 version for the IBM PC on a 5-1/4 inch disk. We have already verified that this version runs on the following computers: IBM PC, Eagle PC line, Columbia PC, Compaq PC. 4. Test version for the IBM PC using the 8087 math co-processor. Note that this is only a test version. We will be very pleased to answer all the questions you might have during your evaluation I would like to meet you in person and maybe COMDEX Las Vegas would be a good oportunity. But my plans for COMDEX Las Vegas are not finalized yet. Therefore the easiest thing would be for you to let me know where you will be staying so that we can eventually arrange a meeting. Sincerely yours, (signature) Philippe Kahn President P.S. You will find in this shipment the package that our customers receive for $49.95. We feel it is a good buy! ENCLOSURE ---END QUOTE--- -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
