L.A. Weekly Article --- Anyone Seen this Before?

by wsmith＠gj.com

There was an article in the August 20, 1999 LA Weekly regarding vintage computers that mentioned VCF 3.0 with a quote from Sam. Don't recall this being referenced before on this list. Go to: http://www.laweekly.com/ink/99/39/cyber-vankin.shtml Sorry if it's been mentioned before. Wayne

Likewise with the Sinclair and Timex/Sinclair machines I collect -- there are many active user groups around the world who share software, as well as hardware groups who have made available devices such as disk drive interfaces, data transfer to/from IBM-type pcs, etc. But nothing for the Kaypro. Perhaps this is because the Kaypro computers weren't "hobbyist" computers -- they were designed and marketed as "business" machines. As far as I can tell there was very little third-party hardware sold for the Kaypro, and they were not exactly designed to be modified (people on the list, please correct me if I'm wrong ;>) Glen Goodwin 0/0

The 1700 is the heart of a disk controller I use with my Timex Sinclair 2068. The system is still available from the manufacturer, but in the event of failure it is of course cheaper to replace the IC than the entire controller. Tony: Please define "modern floppy drives."

HI! Im new to the list. Kaypro '99..

by DD950＠prodigy.net

-----Original Message----- From: Don Maslin <donm(a)cts.com> > >Perhaps the attached 'history' will help. > It helps much. Thanks for taking the time to find that history and post it. I am convinced to start my KayPro Web page now. There are plenty of free Web servers out there. I have a real soft spot for the KayPro and I sense there are a few others that do also here. Time somebody starts a dedicated Web site to honor these hard working machines. Besides, you never forget your first one! :-) If anybody has any scanned photos or can scan some sales brochures etc. , please send them to DD950(a)prodigy.net . I have nothing KayPro left here except a leather cover for the 2X-84. I paid $75 for it in 1984 and used it only to take the machine home LOL. Sure seemed like a good purchase at the time! More of the history is needed and very welcome. I think Kaypro started as a test instrument company under another name and that is were the standard "portable" cases came from for the CP/M machines. ?? Also the history of MicroPo and the rise and fall of WordStar should be included here if anybody will or has written something up. I think it is also an interesting story. This will be a group effort and perhaps we can make the Web site a bit of the home page for this mailing list with pictures of the contributors etc. Regards, ??? <-- KayPro graphics, remember them? ~ Jim Rossbach "640K ought to be enough for anybody."

Picking tubular locks

> For what it's worth - when I worked in the Cooler department here >at Coca-Cola we used a automotive dent puller (which is a kind of >slide hammer) to pull locks in vending machines. We had the hardest >type to break into because we used Abloy locks. I hope this is never necessary for a classic computer! For the DEC and DG machines that I'm familiar with and which used a real lock cylinder, all you have to do is remove the front panel, loosen a nut, and pull the cylinder. It does pay to look carefully before doing this, as when you put in the new cylinder you want the cam in the correct position to activate the microswitches. If you aren't patient enough to put in a new cylinder, you can use small objects (my favorites were guitar picks) to close the appropriate microswitches you need to operate the machine. -- 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

Oops -- I deleted the message mentioning the "hacker's guide" to picking locks. Actually it's a locksmithing guide, if you're thinking of the MIT document. http://www.lysator.liu.se/mit-guide/mit-guide.html http://www.telepath.com/pillar/locksmith.html Anyone who's really interested might also look for a document called "scrtlock.html" or "scrtlock.txt", by Steven Hampton, and which used to be on Stephen Hardman's page. -- Pete Peter Turnbull Dept. of Computer Science University of York

But don't use an XX2247 metal key in those plastic ones on a regular basis. The fluting (combination) on the metal keys abrads the plastic "lock" body. My younger brother is a former locksmith (and current professional geek). He owns an Ace lockpick. It's like an Ace key body with the pin grooves cut all the way up the cylinder and feeler gauges in the grooves with a tension collar above where the lock body would sit on the key. The whole thing is capped with a 1" knurled plastic knob. To pick the lock, you slide all the feelers down to zero, insert the "key" into the lock and give it this special twisting, pushing, pulling motion that's hard to describe in writing. The idea is to bind the pins in the lock and push back the feelers by pressing the pick against the bound pins. He can open a pop machine in about 15 sec. The secondary benefit of this pick is that you can now make a key from the pick since you know all the depths. It's about $70. He made a second one for a non-Ace lock, but he's that kind of guy. No, I don't own one myself, but he did re-key my personal Gorf machine to XX2247 for my convenience. -ethan ===== Infinet has been sold. The domain is going away in February.

Hi, im new to the list, I don't know how busy this list is, but if it's anything like the Fiero list.. there should be at least 100 emails a day. In any case, let me say a little bit about myself... or at least the computers i've had. I used to collect old computers. While I gave most of them to my roommate, I still have quite a few old ones.. 1) KayPro PC-10.. two 5.25" drives, 20mb ST-225/RLL, Herc Monochrome. 2) KayPro 2 - Huge portable CP/M beast... 3) KayPro laptop 4) Leading Edge 386 SX-16 5) IBM PCjr - Fully loaded with drive, 128k mem, all games ever made on cart, and color screen. 6) Amiga 500 with two monitors. 4 shoeboxes of games. 7) Atari XEGM 8) Commodore 64 9) Commodore 128/SX (one of three prototypes ever made, and I took it apart and thew it away because I had no idea it was worth anything. Got it from an ex-Commodore worker) 10) Atari 1040ST Are any of these really rare? Im a big fan of KayPro computers but don't really have very many. I actually gave away my laptop because I had too much junk lying around. I still have the PC-10 (first real computer) but it's stored away in the basement of a house we are leasing out in Northern Virginia.

floppy controller IC (was Re: Fixing a PET?)

by edick＠idcomm.com

The 1770 and 1772, which were 28-pin IC's intended for use only with 5-1/4" drives, the primary difference between them being the step rates they support, were not widely used. I have the 1770 on my AMPRO "Little Board" but the numbers are out of sequence in the sense that the first of their parts was the 1771, followed by the 179x series, with a shot at a 178x group ( intended to fill the gap with respect to M^2FM and (?) hard sectors ) which wasn't around long if at all. The 1791 was an inverted-bus version of the 1793. This inverted bus was inherited from the1771, and was designed to explout the benefit of the inverting bus' slightly shorter propagation delays. One advantage the 1770/72 offered was that they had drivers capable of driving the 110-ohm terminated cable to the drives. Shortly after they released the 1770/72, they started making boards for IBM and compatibles, which either used all their production of the required parts, or made them sufficiently unpopular with their former customers now competitors that they stopped making these parts, among others. They did make a couple of 765-compatible FDC's with cable-driving outputs which appeared on some of their SCSI HDC's and their IBM-compatible boards. I've only got one spare, and I'm hoping I don't need that. If you find these, please let me know.

Fixing a PET?

by yakowenk＠cs.unc.edu

One of the first things to do when you have a screenful of the wrong characters is to whip out an ASCII chart, and look at the binary codes for the characters you've got vs. the ones you expected. Very often the problem is a single-bit change, which narrows down the source of the problem. For instance, the difference between upper- and lower-case ASCII characters is a single bit. Cheers, Bill.

It's probably simpler to buy the correct key. All DEC systems with tubular locks that I've met use a XX2247 key, and all the DG systems use identical keys too (but I don't have my DG key on my keychain at this moment so I can't give you the pattern #.) The later "plastic key" DEC locks can be turned with just about anything - they aren't really locks at all. And replacing a tubular lock of unkown code with a tubular lock with known code is fairly simple. You only have to replace the cylinder (making sure that the new cylinder you get will accept the cam that the old cylinder used to activate the actual switches). Tim.

FS: Panasonic Sr. Partner computer

by rigdonj＠intellistar.net

I have a Panasonic Sr Partner portable computer that I just picked up if anyone wants one. I haven't tested it but I did plug it in and turn it on and it does come up asking for a boot disk. I don't have any software or docs for it so I'm selling it as is. All the fold up covers and legs are there and are intact. It even still has the original power cord in it's cubby hole in the back. It also has a printer built into the top of it. Also FWIW the back is marked "US Sailboard Team". I'll take $35 plus shipping from 32765 for it. E-mail me directly if you're interested. Joe

New Collector - Pointers to Sources

Hello - I am a relatively new collector and new to the list, so this may be a naive question - please excuse. I would like to get my hands on either/or/and a PDP-8/?, PDP-11/?. Where does one look - keep an eye on? Can you point me to places to watch or even places that list places to watch? Any help would be appreciated. Thanks in advance, -- Dr. Randy M.

New Collector - Pointers to Sources

by allisonp＠world.std.com

<I am a relatively new collector and new to the list, so this may be a <naive question - please excuse. I would like to get my hands on <either/or/and a PDP-8/?, PDP-11/?. Where does one look - keep an eye on? Ok, For smaller systems the PDP-11 Q-bus based ones are resonable. They are easy to deal with power wise and space wise. Most of the PDP-11 Unibus systems tend to be multiple 4-6ft racks for reasonably operable systems. Smallest PDP-11 systems are the MicroPDP-11s <one deskside box> and the largest <PDP-11/70> will easily be 3-5 72"tall racks plus disk drives the size of washing machines and require special power(220V 3phase). This line is very varied! Moving the big ones is a non trivial task. In the common but non bussed PDP-11s there are the PRO350 , PRO380 and PDT-11/series. While some argue they are not "real PDP-11s" they are certaily the same instuction set and related members worthy of collection. Size PCish, no special power. You should be able to find them free to inexpensive. PDP-8 series, the 8e/f/m are the easiest to find and work with. A full system can be one box (11Hx21Wx28D) is you use a PC to simulate, or better yet obtain, a teletype so paper tape software can be run. Systems with disks will need at least a small rack in the 30-72" height. Some of the older 8I, 8(no designator) can easily be two to four racks and tax the power budget of standard house wiring and possible the floor <weight!>. There are PDP-8 based systems that are quite small and interesting in the own right. DECmate I/II/III series are aimed at word processing but do use a common cpu (cmos chip that is PDP-8 instructions set). They will run a variation of OS8 <os/78 or os/278). These are easy to find, common and should be very inexpensize to free. Size, desktop PCish. I would suggest researching what you want and what you can store (and power) first so you know what your looking for and at. There are a lot of web sites with pictures and descriptions. You're referenceing a lot of postential machines and narrowoing what you might like is not a bad idea. Allison

You find stuff in the oddest places...

by mtapley＠swri.edu

All, My wife was cleaning out the bookshelf last night and said, "Do we still want this?" holding up a book by Robert Mottola, "Assembly Language Programming for the Apple II", Copyright 1982. My jaw dropped open. I'd never seen it before, never having owned an Apple II. She eventually sort of dimly recalled getting it herself at some point, bless her heart. Anyway the answer to her question is "no". Does anyone here want it, for the cost of shipping? - Mark

3.5"/5.25" adapter kits?

by CLASSICCMP＠trailing-edge.com

OK, it's not *completely* on-topic, but it is a relatively low-tech item and quite relevant for those dealing with 10-year-old hardware: I'm looking for some of the adapter kits (with bezels) for putting 3.5" hard drives into 5.25" bays. The local shops have adapters for 3.5" floppies (with, of course, a big rectangle cut in the bezel) but these don't have a nice plain front bezel, and often the holes in them are in completely wrong places for hard drives. Some shops have kits supplied by Western Digital for their hard drives, but often the mounting holes are in completely wrong positions for Seagate or Micropolis or other brands of drives. If anyone has a large number of the adapters/bezels just kicking around (say 10 or 20) I'd be glad to buy them at a fair price. I'd also be happy to be pointed towards a source of these new. -- 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

DEC VT1000/1200

<Just made a trip to the local surplus shop, and they have a whole cart ful <of DEC VT1000's and VT1200's. Appears to be just a base unit (no monitor, <etc.)...

There is both a terminal line (mmj) and eithernet. If you buy make sure there is ram installed as they are often stripped. It must have at least 2mb. Also there is a rom card that must be there. I have one with VR315 mono and I use it as LAT/IPxwin/telnet decwindows terminal or as DCE. If you play with vaxen this makes a good terminal either networked or via MMJ serial. Allison

If you have access to an Amiga, you don't need any extra hardware (apart from a 5.25" floppy drive of course) to read Apple ][ disks. There is a program called Disk2File that creates plain disk image files. Disk2File is on the Aminet FTP sites. (Since the Amiga handles decoding in software, MFM, FM, GCR and any other coding can be handled.) -- Mark PS: Does anyone have an Amiga 1020 floppy drive that they no longer need?
