What DEC module would be the Q-Bus controller for a TS05 (9-track) tape drive? I just aquired a drive and I'd like to give it a spin. Thanks, Bill

Quest ELF was Top 150 .....

I had (and still have) a very deep junk box. In high school, I had enough of a junk box to build most of the Elf with scrounged parts (I did screw up and stick in some 4001's instead of the 4011's the first time I assembled the Elf. It didn't work so well ;-) Now, my junk box is *much* deeper. I could probably assemble an entire PET PCB and Amiga PCB, just from spares.

Compro, S100 & 8" drives

by edick＠idcomm.com

I don't doubt that it was possible to build quite a good computer from the board selection that the CompuPro line had, at one time or another. I bought about ten combinations they recommended, however, and not a one of them worked, so I sent them back. I still have a couple of their motherboards in various cardcages. I will say one thing against the CompuPro line, though, and I doubt it can be denied. Once there was a standard, I don't believe that any other single manufacturer did more to undermine the standard than CompuPro. Their boards were not all claimed "compliant" to the standard and even those about which that claim was made often had little footnotes disclaiming certain things and indicting where they felt their board didn't comply precisely. Since that set a model for others, even if they didn't originate the practice, because they were at the bottom of the price scale, their non-standard and non-compliant boards were proliferated throughout the S-100 world, spreading non-interoperability throughout. This lead people to throw up their hands at the prospect of continuing to use S-100 systems in favor of the relatively risk-free SBC's which were becoming VERY popular, e.g. Ferguson Big Board, Ampro, et. al. and offered CP/M standard media compatibility at the disk level and all the basic features built-in.

N8T97N IC, what is it?

by edick＠idcomm.com

One other item, aside from speed to be considered when using this part, is the current it will sink. The LS variety was slower, basically because it used a slower technology. The 8T97 used essentially the same technology internally as the SCHOTTKY parts the various vendors sold, but it had stiffer outputs, i.e. could sink/source more current. Almost any part which was as fast and would source/sink as much current, will generally bring about the same behavior in the rest of the circuit. If the edges become too steep, as you might see in the form of too much ringing or overshoot/undershoot, soldering little 1/8-watt resistors in series with the outputs will help. I'd say start with 47 ohms and go as far to the smaller side of that as you like. Fairchild actually made a version of their "F-series" logic with 33-ohm resistors built in to minimize problems from both ground bounce and output edges being too steep. One other thing that helps somewhat is to solder a small (<.001uF) high-frequency cap between power and ground on the IC, straight across the back. The leads are long, but it will maintain enough local storage to help with the ground bounce.

That awful show on TNT

by kaikal＠MICROSOFT.com

Sellam doesn't like the movie because he's an early Apple devotee, and the movie portrays Steve Jobs as an acid-dropping, drug-pushing, commune-living, personal-conviction-abandoning, illegitimate-daughter-fathering, beyond-workaholic, universally-disliked-yet-adored, employee-abusing, god-complex-nurturing, business-disrupting idiot whom one expects to have his employees drink hemlock-laden Kool-Aid at any moment. Oh, and Wozniak is portrayed as a small, fuzzy bunny. Does that about sum it up? Kai p.s. the Microsoft contingent gets off rather lightly by comparison, with Bill Gates shown as merely a shrewd, somewhat ruthless, absent-minded businessman with personal hygiene issues. Paul Allen is indistinguishable >from Wozniak in the film, just standing in the background of shots, and has about 30 seconds of screen time. Steve Ballmer, however, is played by Krusty the Klown from the Simpsons. -----Original Message----- From: Sellam Ismail [mailto:dastar@ncal.verio.com] Sent: Monday, June 21, 1999 11:33 PM To: Discussion re-collecting of classic computers Subject: Re: That awful show on TNT On Mon, 21 Jun 1999, Tony Duell wrote: > > I'm virtually apoplectic about this garbage that some of you may watched > > tonight on TV (I certainly did NOT watch it). > > For the benefit of those of us who don't get American TV, could you > please explain what this programme (show?) was and what it got wrong?

This coming Saturday, 26th June 99, will be another in an endless series of TRW Ham Radio and Electronics Swap Meets.. at the TRW Plant in El Segundo, CA, from 7:30 to 11:00 am. The meet is held on the last saturday of every month, no matter what. From the 405 (San Diego) freeway, take the Rosecrans exit and go west 1 mile to Aviation. Turn left (south) on Aviation [under the Metrolink bridge] and go down about four blocks. The TRW facility will be on your right, and the Meet is held in the southernmost parking lots. I will be in spaces J21 and J23, if anyone wishes to come by and heckle me in person. If someone has an item or two to sell, let me know via private e-mail and Arrangements will be made. Due to Ham Field Day activities, no brunch or will be held after the meet this time. *Next* month, however.... Cheers John

Not everything is available, but a fair amount of stuff from the 60's and 70's is available as kind-of nicely Xeroxed copies of the originals. Some of the copies are from microfiche and aren't so nice. It's hard to tell beforehand how nice the copy you end up getting will look! If you don't know the part number, a very handy tool is the DAS (Digital Assisted Services) searchable catalog, at http://www.digital.com/info/DAS-Catalog/dassearch.htm For example, I typed in "RX0" and it came back with these part numbers and prices: H771-A Pow Supply RX01 (RX11) 60 Hz $276.00 M7726-00 RX01 Controller $405.00 M7727-00 RX01 R/W Control $152.00 M7846-00 RX01 Unibus $426.00 M8029-00 RXV21, Q-bus RX02 Interface $381.00 M8256-00 RX211 Unibus RX02 Interface $518.00 EK-ORX01-MM RX01/08/11 Maintenance Manual $ 84.00 EK-ORX01-OP RX8/RX11 RX01 Floppy Disk Sys $ 21.00 EK-ORX02-UG RX02 Floppy Disk System Users $ 21.00 EK-RX012-PS RX01/RX02 Pocket Serivce Guide $ 42.00 Now clearly not all the RX01/02 parts that ever existed are in the above list, but it's a start. And it also shows you how DEC manual part numbers are often constructed; "-MM" is Maintenance Manual, "-UG" is User's Guide, "-PS" is the Pocket Service Guide, etc. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

IBM book...

by mid＠auk.cx

Does anyone have a copy of the "IBM PC Network Technical Reference Manual" (c. 1984) that they could part with / copy/scan a few pages out of for me? I'm trying to write an RPL loader daemon and can't seem to figure out a few things about the protocol. (I'm trying to boot an IBM 8227, which is not-so-classic as the above book is.) Also, does anyone know of something (besides LANtastic, which I can't get to work), that will speak such an old thing as IBM "FIND/FOUND" RPL?

DEC Handbook, What on earth?

>I just got a box of doc's today in the mail, and I'm totally fascinated by >two of them. They're nicely done copies!?!?

If you order out-of-print manuals from DEC (err, Compaq) today, they run Xeroxes off from originals - there's a special name for the facility they use to do this, but I can't remember it at the moment. The resulting document sounds very much like what you're describing. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
