update to "here's the list..."

by edick＠idcomm.com

It's unlikely I'll do that, since of the many hundreds of boxes of 8" diskettes I owned at one time, there were only two of the hard-sectored ones. I recently had a local NRC contractor phone me up after a long chain of referrals, to inquire whether I could replace a drive for them and I had to ask them to provide me with a disketted with which to test the drives. I believe I had one partial box of Memorex diskettes which came with an old NBI word processor which used Memorex drives and an i8008, which , by the way, is now a "high-tech tie-tack" I occasionally wear. There was also an odd box (possibly new, possibly full) of 10-sector hard-sectored diskettes. I don't know what their use was, but I had some GSI/Siemens drives which could operate with either type and soft-sectored ones as well. In the unlikely event these turn up, I'll let you know. regards, Dick ---------- > From: Merle K.

FS: IBM PS/2 Model 70-386 (25 mhz) procesor boards

by rhblake＠bigfoot.com

I have 4 boards that go to IBM PS/2 model 70-386's, the 25 mhz version to find homes for. These are the smaller processor board that mount to J1 and J2 on the base motherboard and has the 80386DX-25 on it and has the socket for the 80387DX-25. If you have a bad machine, or just need a standard Intel 80386DX-25 chip, then this is for you! The picture listed at http://www.pc.ibm.com:80/bookmgr/pictures/s52g9971-picture-77-zoom.gif shows the layout of the entire board and the ones I have are the small board that #6 points to. The standoffs to mount the board are NOT included. All have been tested with and without a 387 math processor and function great. How much? $5.00 each plus a few dollars shipping. They don't weigh much so I imagine they should ship cheap. USA ad APO/FPO addresses only, payable by either money order or cash (if you trust the mail that much). If someone wants ALL FOUR right off the bat then I can go $16 for all of them, plus a still small shipping fee. Drop me a note by direct email and please include your zip code so I can guess-timate shipping. My guess is probably $2 will get one of these to most places in the lower 48.

There's a fair amount of documentation the corresponding software to which, sadly, had to be tossed with the other 50K or so 8" diskettes I have ditched over the past year.

Kip, I enjoyed your article. I have a IBM System 360 control panel complete with the 360 metal bar that goes above the panel. Let me know if you know anyone that would want to buy it ... it would be a great retirement gift or an excellent office piece. It is about 3' by 4' and would fit on a wall. Attached is a pic.

Wanted: TeleVideo CP/M machine(s)

by douga＠email.com

Greetings, I'm looking for a TeleVideo CP/M machine, particularly the TS-803 or TS-1603. If you have one of these computers, or one similar to this one (not including the portable), I'd be interesting in buying it. Or, if you have suggestions on where else I might look for one, I'd really appreciate it. These were great machines, but they're hard to find now! Actually, I may be interested in two of these, if they're available. This may turn into a crazy project, but I have the idea of taking one of them and replacing the guts with a standard PC motherboard/hd/ram/power supply combination to run Linux on it. The TeleVideo 803/1603 has a unique case, which would make for a great looking computer even today. The trick would be maitaining compatibility with the keyboard cable and monitor; not to mention fitting the components inside reliably. But what a coup it would be! Thanks. I'm in the Seattle area, fwiw. Doug Auerbach

So far, I've only found the one set of Dazzler doc's and software, and the software is on paper tape. I believe there's still one dazzler set floating around, though. I still have a few hundred 8" diskettes, of which maybe ten or twenty will be hard sectored, with holes on the outside of one box and on the inside of the other. I may never find these, however, as they were stored in a part of the basement now buried with "other" stuff. ONly time will tell.

by edick＠idcomm.com

I do have a boot disk for the 806. I'm not sure where it is at the moment, but it's within 10-12 feet of here for sure. Since I haven't used a CP/M box of any sort for a long time, I'd be afraid to guess how I'll replicate it. The 806's I have are 20's but that's a combination of a 20MB hard drive and about half a dozen bytes in the bios. I used to switch between a ten and a 20 by patching these bytes. Email me in a couple of days and I'll try to have a firm answer for you. ---------- > From: Merle K.

Noisy ST 251 HD

by allisonp＠world.std.com

<I am really glad to find I can use the ST-251 in my DEC <Pro 380 instead of the Quantum Q540, since the later drive <is rarer, older, and perhaps (in my experience) not too <reliable. And has a smaller capacity, of course, and is <a full-height drive. The ST251 is well known for it's bad bearings and spindle problems. The Q540 is known for running forever. The later know as a RD52 is very common and very hard to kill. I have about 8 of them (all good). Generally I will not use a st251 again... I spent to much time helping PC support at DEC with disk failures in VAXmates (st251s aka RD32) where the older st225 was rock solid. <Is there a better drive (MFM) with equivalent geometry? <(820 cyls, 6 hds, 17 sec) or maybe with 6+ heads and 820+ <cylinders (that might work, too?). Half-height would be <nice, like the 251, because if I ever get another HD <controller card, I can put two drives in my Pro 380 (only <one drive per controller card, and supposedly only one <per Pro chassis, but the 251 probably uses a lot less <power than the Q540, so two drives should be OK). the q540 is 8x512 (31mb)... and the 251 is 6x820 (40mb). Also the 540 is several times faster (voice coil VS Stepper). Allison

DEC Pro memory card upgrade

by djenner＠halcyon.com

Here's another Pro 380 question. I asked it on the pdp11 newsgroups and got no answers. Maybe you can do better here! Has anyone ever upgraded a memory expansion card (000034, plugs into slot 0-5 of the CTI bus) from 64Kbit to 256Kbit chips? (256KB to 1MB) You can easily do this with the memory card that plugs into the mother board--there's even two empty jumpers waiting for stuffing. Is it possible? If someone thinks they can do it, I'll gladly contribute a board for a proof-of-concept test. You keep the board as long as you tell me how to do it! Dave

Hi all. I'm feeling clueless at this point. I've found the CPM caldera site and downloaded everything that looked appropriate, but I'm completely unclear how to turn this into a kaypro boot disk. I've put a 360k PC drive on my PC in the hopes of using it to write the disk. I've also downloaded teledisk.

Introduction

by rickb＠pail.enginet.com

Greetings, Classic Computer Fans, I've just subscribed. I've heard about this list for a long time, and have been recommended to check it out by a number of folks, so...here I am. My name is Rick Bensene. I live near Portland, Oregon. Some here may know me from my old calculator collection (which I'll shamlessly plug here: http://www.geocities.com/SiliconValley/Lab/7510), which is my substitute for collecting old computers. (Calculators take up less space) I've been involved with computers since the early 1970's. I currently work as a technologist at a large Electronic Design Automation software company. I've always loved computers, and though I don't actively collect them, I am hoping to live vicariously through all you folks who are active in collecting. I have a few older computers that I've run across, mostly as orphans. These include a Tandy 100 (who doesn't have one of these?), a Tandy 600, a Sun 3/50, a Sun 4/360, A couple of Tektronix 6130's, a Tektronix 4132, and a Tektronix 4319. I worked at Tektronix for 13 years, from '77 through '90, so I have a particular affection for Tektronix equipment. I've used/administrated/hacked/programmed quite a range of computers, ranging from a CDC Cyber 73 and later Cyber 176 at Tektronix, VAX 11/780's running both VMS and 4BSD Unix, A Gould Powernode 9080 (interesting, all ECL machine with dual processors), a DEC PDP8/E(OS8), a DEC RSTS system (running on PDP 11/45), varios 11-based systems running RT-11, HP 2000C, E, F, and ACCESS timeshare systems, Apollo Domain OS (DN300, DN3000-series), Sun from as early as the 68K-based VME-bus systems to latest Ultras, early HPUX machines (700-series workstations), IBM RT workstation, IBM 360/30, early micros (Altair, IMSAI, North Star Horizon, ProcTech SOL), Commodore PET, TRS-80, TRS-80 Color Computer, homebrew stuff (8008, 8080 and 6809), Tektronix 4051, Tektronix 6130/4132, Tektronix 4081, Tektronix 43xx-workstations, Alpha Micro (from the early LSI-11-based days), an old (early 1960's) computer made by 3M (can't remember the model number, but I'll write up some memories about it for the list), a SCM 7816 (strange beast, a cross between a computer and a calculator), and of course, PC's since the original. I've programmed in FORTRAN, COBOL, just about all variants of BASIC, C, Perl, Pascal, and in assembly on PDP-8, PDP-11, IBM 360, Interdata 7/16, 8008, 8080, Z80, 6800, 6809, 8051, 8085, 8086, National 320xx, and 68K. I'm looking forward to sharing memories with the list, and, as mentioned, hearing about your memories, and all the great collector finds out there. Best wishes to all, Rick Bensene

here's the list . . .

by edick＠idcomm.com

Here's the list of S-100 hardware I've turned up in the last mess of boxes, etc to be unearthed in my basement and transferred to open air storage in my carport. This is only a partial list of what I've uncovered this afternoon, and an extended list will be available later today. There is other stuff, not yet inventoried, but that will be later, if at all. Cromemco 21-slot unterminated Motherboard in VECTOR cardcage - assembled but never used. MSC (later became XEBEC) 9391 5Mbps HARD DISK controller. This controller is functional and capable of handling 16 or fewer heads at 512-byte or 256-byte sector sizes and steps the drive at 3ms per step, which was typical back in 1980. This was the one we used most. XCOMP HDC 2-board set. These are set up for 8" drives only and require one write the BIOS patch or back end driver oneself. Franklin Electric 3-UART serial I/O board DC Hayes Micromodem-100 including documentation and software SSM IO4 2P+2S I/O Board with documentation. No software was provided since everyone wrote their own BIOS patches for it. North Star Z80A CPU card California Computer Systems 2810 Z80A CPU card, with monitor prom. California Computer Systems 2422 FDC for both 8 & 5.25" drives, with monitor/boot prom California Computer Systems 4-port serial card. California Computer Systems 64K DRAM card Vector Graphics 64K DRAM card Extended Processing "BURNER, I/O" board - Prom Programmer with UARTS and PIO not installed. Processor Technology "CUTS" cassette interface? board BIOTECH ELECTRONICS BCT800 graphics board - uses AMI 68047 chip and 12 2114's to produce 256x192 graphics and text. Cromemco Dazzler video graphics board pair - There are two, but only one set of doc's and software including paper tape. MITS Modem board - a MITS serial board with a "MODEM BD" rider.

Chinon XT SCSI host adapter card

by mark_k＠iname.com

Hi, I have a Chinon 8-bit ISA SCSI host adapter card, which came with my old Chinon CDS-435 SCSI-1 CD-ROM drive. The part number printed on the card is 66201UCSEP02. The only provided driver software is for the Chinon CD-ROM. To use other SCSI devices with this, I need appropriate drivers. What I want to know is, was any "universal" driver software ever made for this card, by which I probably mean an ASPI-compliant driver? If anyone has any idea, or a suggestion of where might be a better place to ask this question, please tell. BTW, Tony Duell would really like this SCSI controller; *every* chip on the card is simple 74-series TTL. :) -- Mark

Looking at my machine, I can see that the drive wheel for the tape drive is pretty funky. I haven't tried to use it (don't have a cartridge) but, it'll probably fail. Is there a common source for drive wheels? What about the cartridges? Thanks, Steve Robertson - <steverob(a)hotoffice.com>

His boss asked him to fix a 386 because of a quite spectacular Windows 3.11 crash. My friend couldn't even format the hard drive using the traditional MS-DOS format programs so he tried the Packard Bell diagnostic disk that had come with his old 486 (terrible machine, everything was built into the motherboard). It turned out that it was doing a low-level format which killed the IDE drive. I've never understood why Packard Bell who sold many of their computers to novices would ship something that could damage the hardware. To save face my friend just said the Windows crash had messed up the machine and I let him have one of the 40Mb hard drives I owned at the time. -- Gareth Knight Amiga Interactive Guide | ICQ No. 24185856 http://welcome.to/aig | "Shine on your star"

Cromemco Dazzler

by edick＠idcomm.com

There are supposed to be three of these board sets, though I saw one or two for the first time in 20 years yesterday. One appears to be complete with doc's and software, though the others, which I know were "played with" by my associates, may not be as complete, and some duplicating may be called for. I'm pretty certain that I can lay hands on two of these sets more or less right away, including one set of doc's and software, which I believe I held in my hands yesterday. The quandary arises out of the fact that there is at least one other board set, and i don't have a running CP/M box, since I'm not a collector. I've had a couple of modest cash offers, but would rather leave $$$ out of the equation if possible. If you have anything swappable, I'm interested in single-board computers, preferably small and simple, with documentation and firmware so I can USE them for something. If you're a Cromemco addict, you may be interested in the fact that I have a couple of functional PERSCI floppy drives, which were commonly available (though EXTREMELY expensive at the time) with the Cromemco systems back when Computerland used to sell them. These are single-sided (model 277) drives, of which one is packaged as an external unit complete with power supply, while another enclosure is in some less-than-functional state and extensively disassembled. I've recently looked at the power supply and noted that the regulator circuitry is missing. I also have parts of a third unit which is useable as parts only. What's probably more interesting is that I have the maintenance documents for these PERSCI drives. These are voice-coil-driven rather than stepping-motor-driven units, (for which provision was made on the later Western Digital floppy controllers) capable of stepping microseconds rather than milliseconds. I also have quite a few enclosures, power supplies, cardcages, motherboards, and other boards, mostly CPU's, FDC's, memory and I/O, some as yet unassembled, some under repair, some fully functional. Does this give you any suggestions? regards, Dick ---------- > From: Lawrence LeMay <lemay(a)cs.umn.edu> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Cromemco Dazzler > Date: Saturday, February 20, 1999 9:30 AM > > [Charset ISO-8859-1 unsupported, filtering to ASCII...] > > I was digging throught the pile of "stuff" from days of old, and find I > > have a board-set (S-100) which is a Cromemco (remember them?)

Is this the same thing perhaps as a Dick Smith >VZ200? As Andrew Davie said, seems so. I have the VZ200 and VZ300 as sold by Dick Smith, and the VZ 200 manual says copyright Video Technology 1983 on the first page. To all "Oz-nerds" (as opposed to Yank-nerds or Limey-nerds?:) - in the book "Programming the Dick Smith Electronics VZ300 Personal Computer" by Tim Hartnell, there is a section on attaching a disk drive (Cat X-7302) via a floppy disk controller (X-7304) which can take two drives. You also need the 16K memory expansion (X-7306). I have the latter, but I have never laid eyes on a VZ disk drive. I assume they are rare - if you had the sort of money I expect they wanted for them in 1986-7 (the system units were still being advertised in Aust Personal Computer in June 1987 for $A169 including datacasette and 4 programs) you would have bought a better computer! The boot screen with the disk drive attached is supposed to say VIDEO TECHNOLOGY DOS BASIC V1.2 READY So has anyone ever seen that? Phil in Brisbane, Australia.

I need a ST-419 hard drive

by rigdonj＠intellistar.net

Jeff, I tried a ST-251-1 but it wouldn't work. Here's the story: I picked up a HP 9133XV drive with a bad drive in it. The XV is the one that you can partion into 4 so that it looks like 4 HP 9895 floppy drives to the system. It's the only hard drive that can be used on the HP 85, 150 and some of the others. This one has a Seagate ST-419 drive in. I replaced it with a Seagate ST-251 that has the same number of heads but more tracks and is smaller and faster. The system recognizes if but it won't format it. It says that the drives are bad. I'd like to get it running again since the XV drives are hard to find. The 251 does have fewer sectors (17 vs 32). I don't know if that's why it failed or not.

I'm keeping the C= disks, but if anyone in Oz is willing to pay postage, they can have the Ataris & carts (I don't collect 'em - but for $10 I couldn't say no :-) ) Oh yeah, there's a Dick Smith VZ200 put aside for me as well, again, I don't really want it, but will forward it to someone who does (they want $8 for it, includes tape deck & two joysticks). cheers, Lance

Noisy ST 251 HD

by djenner＠halcyon.com

I have a noisy ST 251 hard drive. It sounds like the bearings. Is it heretical to think I may be able to lubricate the bearings? They appear to be easily accessible on the bottom of the drive. Thanks, Dave

Dayton Hamfest

by Watzman＠ibm.net

The Dayton Hamfest is a fabulous show. It is THE LARGEST amateur radio convention [it's "official" purpose]. The Hara arena is a very good size facility, I'd guess in the over 100,000 sq. ft. range (perhaps WAY over), and it's all indoor, heated/air conditioned [not that it works with 35,000 people in the facility], and all commercial vendors, many, many of which are used computer and surplus dealers (there is lots of new stuff also). It's about 60%-70% computer, the rest general electronics and communications [radio] equipment. The flea market takes up the entire parking lot, in excess of 2,500 vendors. There are many commercial exhibits in the parking lot also, you will find a number of very large tents (10,000 square feet range each). Mendelson surplus always has a large tent, and almost every year Radio Shack [as in Tandy] collects their entire surplus and returned merchandise stuff from all over the nation and sends it all to a big tent at the Dayton Hamfest where it is sold for often ten cents on the retail dollar. However they didn't do this last year, for the first time I can remember, but they still had a huge indoor exhibit with many items, new, at 25% to 50% below normal store and catalog prices. The show is logistically difficult to attend for several reasons. First, it brings in so many people [over 25,000 plus a large local population] that poor Dayton, which is hardly a tourist mecca, is complete swamped. You can forget about finding a hotel at this point, the people who do this show get their reservations a year in advance. You may have to stay in Columbus or Cincinnati [both about 70 miles away], fortunately both are directly on an interstate highway and it's not a bad drive. The other problem is parking, since the entire lot is flea market there isn't any ! There are some LARGE fields around the complex that are used for parking, expect to pay $5 to $10 per day, and they are not paved, or very close, which become a real issue in bad weather. Then there are remote lots with busses, but that's a hassle also. The show is May 14, 15, 16. Here is an alternative, the Dayton Microcomputer association has a twice a year computer show at the same site. It's just about as large as the Hamfest, and it's ALL computer. There is no flea market, the parking lot is used for - surprise ! - PARKING ! It's almost like having 3 Dayton Hamfests a year, except that two of them don't have the flea market. This year's dates (it's only a two-day show): Spring: March 13-14 Summer/Fall: August 28-29 I plan to attend all 3 events.

I don't read German But the pictures are perfectly understandable... http://www.zock.com/8-Bit/D_Laser200.HTML >> VZ200, eh? Interesting. Maybe you Oz-nerds can shed some light on this. >> I recently acquired a Dynasty Smart Alec Jr. Its a small computer with a >> chiclet keyboard. Almost reminds me of a Mattel Aquarius. Anyway, on the >> bottom the label reads that its a model VZ200, made by VTech (or Video >> Technology) circa 1982.

DECMate III

by allisonp＠world.std.com

<I finally picked up the DECMate III that was at my uncle's house. The WPS <binders and software got thrown away, but I suppose I could download that <stuff from SunSite. I have been told that this is a PDP-8. Is it possible You can get os/278 as well. <to use 8" disks with this? It only has a dual 5.25" drive (RX50?). Yes they are RX50s. There was no provision for 8" disks on the DMIII. FYI: 8" RX01 were 512blocks (256k), 8" RX02 were 1000blocks(512k) and RX50s are 800blocks (400k). So the 5.25 media is really nicer. <Forgive me, I am not familiar with DEC machines. Oh, and one more thing. <Can the screen/keyboard be replaced with a PC running a terminal emulator? <The screen is attached via a 15-pin cable but otherwise resembles a <VT-220. Thanks. No. It expects a VRR201 monitor and a LK201 or LK401 keyboard. There are two serial ports, modem and serial printer. The chances of getting those are really good around here (eastern MA) and if by may you don't have one the MIT flea is a good shot. Allison

I need a ST-419 hard drive

by jeff.kaneko＠juno.com

Hey Joe! I went down to the junkyard near where I worked, and managed to turn not one, not two, but *three* HP 9133XV's! There were also "V"'s a "D", and an "H". I grabbed one of the XV's, and plan to test it with my 9816. If the platters are in good condix, would you be interested? I could even just pull the HDD unit (14.8Mb :) and send *that* if you like!

The manual I have was a 3rd edition dated 1982, (the 2nd 1981) so he must have sold quite a few of these. The company was known as CompuKits and TMK was marketed widely in N. A. His name IIRC Was Jim Reiss. I'll have to see if he's still at my old alma mater. It's possible the one you're talking about was a later model if he joined the Uof T faculty. The built kit looked really neat. Everything was entered from the console by toggle switches or pushbuttons and it had LED indicators. It had provisions to expand memory allowing use of Motorola's MIKBUG monitor ROM to interface with a T-T or RS232 device as well as a provision to add 256 bytes of non-volatile memory. You could expand memory up to 8k x 8 static ram and suggests you use the less expensive and smaller chips like the 2102 rather than the 6810s used in RAM 1 and RAM 2. Would be an interesting project to build one, if I ever get the time. ciao larry lwalker(a)interlog.com
