In the ever on-going attempt to consolidate space in the garage and related warehouse spaces (read that - pay less rent!) I'm offering up another random piece that is lurking about and is not a major item of interest to me. A Tektronix 6130 workstation (circa 1984). I'm not horribly familiar with it, but I'll tell you what I know about it. (going from a Tek brochure) 32016 CPU, 32-bit display list processor, 32081 Floating Point Processor, 1MB memory, 360kb 5.25 diskette drive, 20Mb hard drive, dusl RS-232 interface, IEEE-488 interface, LAN interface, UNIX derivitive operating system (Utek?). Known hardware in the warehouse includes: CPU chassis, console display, graphics display (color I believe), keyboard, (at least one) box full of extra boards and parts, asstd. docs and manuals... I think (but don't hold me to this) I recall seeing a mouse and diskettes somewhere but I'll have to go digging. It was reportedly operational when it came to me a couple of years ago. I've never tried to start it up. This may be a pre-production or engineering model just judging from some of the tags/ID plates (or lack thereof) ...and what do I want from this??? Something interesting that fits in more with my primary interests (PDP-8 stuff is good, or check the 'wish list' on my web pages), or enough of a $$ offer to make it worth my while. (over and above shipping costs, unless you are going to pick it up) B^} So...? -jim --- jimw(a)computergarage.org The Computer Garage - http://www.computergarage.org Computer Garage Fax - (503) 646-0174

IBM 360/370 emulation?

by DSEAGRAV＠toad.xkl.com

Anyone know where I can get my hands on an emulator of an IBM 360/370? Always wanted to meet one, and I'm curious. (Taking a shortish rest from working on the '10. I'm into paging and such now and it's giving me fits.) Failing that, anyone know where to get documentation so I can hack one up after I'm done fighting with E10? Altavista search turns up junk matches (resumes and such) and a couple emulators that have disappeared. -------

WTD: Mostek Z-80 reference booklet

by bill_r＠inetnebr.com

I've got a scanned version on my web site; I think it's in the classic computers section under documentation. It's there somewhere, scanned at high enough resolution to be printed and be able to read the tiny little text... >Apropos the post earlier today, from the person with a Z-80 reference card >to give away ... > >Does anyone have a spare Mostek Z-80 reference booklet?

WTD: Mostek Z-80 reference booklet

by pat＠transarc.ibm.com

Apropos the post earlier today, from the person with a Z-80 reference card to give away ... Does anyone have a spare Mostek Z-80 reference booklet? These were the tiny little booklets, that (among other applications) Radio Shack packaged with either T-Bug, or with the Editor/Assembler (for the TRS-80 Model 1). I used to have one a long time ago, but can't seem to find it anymore. --Pat.

Famous & infamous computers of the 70's & 80's.

At one point (oh, almost ten years ago now) small "adapters" were readily available for a few tens of bucks to let you use true blue IBM PC keyboards on machines expecting AT keyboards. I haven't seen these being sold for many years, but they must occasionally turn up at the usual outlets. Personally, I don't really like the IBM PC keyboards, I'm far more agile with a VT100 or DEC LK201 at my fingertips :-). >ON-Topic_analogy: The phrase "SINGLE-Density" never existed until the >marketing people started calling MFM "DOUBLE-Density". Good point. When did IBM introduce MFM "double-density" MFM 8 inch floppies? I'm guessing 1975 or 1976, based on samples I have here. The DEC RX02 was just a little bit later, IIRC. -- 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

> Date: Sun, 26 Dec 1999 01:21:56 GMT > From: "David Vohs" <netsurfer_x1(a)hotmail.com> > > Here is a varied list of computers (and computer-related things) that were > either famous or infamous for various reasons > > First, the infamous ones > > Computer with the worst keyboard: (tie) Sinclair ZX-81/Timex Sinclair 1000 & > IBM PC Jr. I agree with the other respondents, the original PET keyboard is hard to type on period. At least on the PC-jr you had decent spacing. Later pet keyboards were a vast improvement but not the best. Atari 400 could also be on the list, but the touch sensors were better then Sinclair's. > Computer with the slowest disk drive: Commodore 64(C). A sad tale goes with that distinction, it is capable of much better speed but certain marketing/design choices were made for the wrong reasons. :( > Most infamous computer by price: Apple Lisa. I remember seeing that in a computer store, $10,000, wow! had nice demos, though. > And now the famous ones > > Computer with the best keyboard: (tie) Commodore 64(C), & TRS-80 Model 12. > Computer with the best speech synthesizer: TI-99/4A. There are sooo many, I would have to suggest the "Alien Voicebox" (Atari and Commodore VIC/64) that sythesiser has (software controllable) pitch/speed and is able to SING! ;) Amiga was good. As for Commdore 64 voice sythesisers I can list SAM, Easy Speech, VoiceMaster, Votrax, Alien Voicebox, Commodore's, and a couple magazine projects.. > Most famous "vaporware" computer: Xerox Alto. Vaporware should reflect something that was promised but never saw the light of day. I would put the Commodore 8-bit LCD in the running, man did I WANT one of those! > Computer with the best sound hardware: (tie) TI-99/4A & Commodore 64(C). Yep, Amiga also should be on the list. > Computer with the coolest pitchman: William Shatner. (VIC-20) Even though I hate IBM I thought the chaplinesque hobo was nice. > Computer with the coolest case design: TI-99/4A. (The case reminds me of a > Delorean. Remember those?) I liked the Atari 800, pop open expansion bay, four joystick ports (in the front no less!) > Computer with the best introductory commercial: Apple Macintosh. ("On > January 24, Apple will introduce Macintosh. And you will see why 1984 won't > be like "1984"".) I agree. Here are some more: Most imfamous sales life: Mattell Aquarius and Coleco Adam. Most famous Sales life: Commodore 64(c) estimated 17 million sold for one model. Least Innovative initial release: IBM PC (only really new features were the price tag and the logo) Most overrated antique: MITS Altair (surely not as unique as some, and way more production than others) Most infamous bug-box: TRS-80 (earned the nickname Trash-80 for all the service work needed), second possibly the original PET (the original ROMs were pretty buggy) Most infamous Computer Monitor: Osborne 1 with it's 4" (?) black & white display. -- 01000011 01001111 01001101 01001101 01001111 01000100 01001111 01010010 01000101 Larry Anderson - Sysop of Silicon Realms BBS (209) 754-1363 300-2400 baud Commodore 8-bit page at: http://www.jps.net/foxnhare/commodore.html 01000011 01001111 01001101 01010000 01010101 01010100 01000101 01010010 01010011

I need 72 pin parity simms

by lemay＠cs.umn.edu

Well, another christmas spend repairing and upgrading all my siblings and nephews computers. Very relaxing, actually. And I get to use up all the junk I buy over the year at onsale.com ;) But, my nephews need more ram in their computer. It spends most of its time thrashing virtual memory onto a slow bigfoot hard drive ;) If anyone has some 72 pin parity simms they want to get rid of, I could sure use them. I would need either 4 8Meg simms, or better (ie, 2 16 meg or 32 meg simms would also be great). I have dozens of 4 meg simms, but the motherboard (genuine IBM) only has 4 simm slots... -Lawrence LeMay lemay(a)cs.umn.edu

PRS01 paper tape was(Re: PDP-8/e restoration (wasRe:Oscilloscopes)`)

by mbg＠world.std.com

>So what you are saying is I can post most versions of every OS and state >that they may only be used on Supnik's emulator. I guess it will be up to >the honest end-user. No... only those OSes which are covered by the license (regardless of how restrictive it is) should be made available for general download. Please do NOT make later copies (in the case of RT, copies later than V5.3) available because if you do, it demonstrates to Mentec that we (the hobbyist community) might not be able to be trusted with what they have made available, which might make them less likely to remove the restrictions. The current restrictions are: 1) Only those operating systems and layered products earlier than specific releases (in the case of RT, V5.3) 2) For us ONLY on the accepted emulators (Supnik and Viking, possible Charon). 3) The license does NOT grant the right to use the software on REAL HARDWARE. So, please adhere to the terms of the license which has been arranged with Mentec/DEC/Compaq or there may not be another one (or the current one could be withdrawn).
