Okay, I asked a simple question. Got 3 differnt answers, and folks referring to "over here" and whatever. I live in the US, I will need to go to radio shack to build this.

cocos and stuff

by kaikal＠MICROSOFT.com

The Color Computers were: Color Computer 1: Silver/black, 4K-64K Color Computer 2: White, 4K-64K Color Computer 3: White, 64K-128K Micro Color Computer: White, tiny, 4K I've never heard of a TDP-100. The Color Computers had ROM BASIC and most serious users ran an operating system called OS-9 which was kind of like TopView. Expansion is via the cartridge slot. The floppy disk interface was implemented as a cartridge, with the floppy OS in ROM in the controller cartridge. CoCo floppy drives are rare. Floppies stored 156K. There was also a hard disk cartridge, believe it or not; plus, a Multi-Pak Interface which allowed you to connect four different carts and switch between them. There are lots of CoCo fanatics around, somebody probably sells parts and maybe even schematics. In regard to the Inboard/386, as I recall it had 1MB 32-bit RAM on the card, and could optionally use motherboard RAM which of course ran at a much slower rate. My memories may be confused with the Inboard/386 AT, but I seem to remember a daughtercard which could store an additional 2MB or so. Good luck finding a daughtercard though.

Apple II hardware design

If you look in the Apple ][ red book, there is a little circuit in there that plugs into the game I/O connector and drives a 20mA current loop. Alongside there is a short assembly program to drive it. Now there is a bit-banger. There was an unspectacular serial card for the ][. I don't recall it being a bit banger, just that the combination of it and the printer I was using at the time (an IDS BrighterWriter) wasn't smart enough to manage any sort of common flow control, so that I had to run it at 300 baud. I thought it had some sort of UART-like thing, but maybe my brain is going again. Hmm, I think it was called the Asynchronous Serial Interface or something like that. There was also a Synchronous Serial Interface that (I recently found out) was the Silentype printer interface. I don't remember the Mountain Hardware CPS card that well, and I feel very good about that based on what I do remember. Now there was a klu[d]ge. The Apple Super Serial Card was designed around a 6551. There were a couple of other cards designed around the 6850. The Hayes Micromodem ][ was one of these. ... Strange as it seems today (now that I have done some programming around PC-contemptible serial ports), the Apple ][ serial cards and software generally worked by software-polling-hardware. The only serial card I can remember supporting interrupts was the Super Serial Card, and I can't say that I ever saw it used that way. Certainly none of the "standard" software required it; interrupts just weren't generally done on Apple ][s. -Frank McConnell

Vector 3-5030

by dbetz＠xlisper.mv.com

Does anyone know anything about the Vector 3-5030 from Vector Graphics? Is it considered a collectable? I recently found one at the town dump and brought it home. It displays some sort of ROM monitor screen when it comes up with version number 4.2. It has a dual floppy drive but no software. I assume it is a CP/M machine since one of the boards in the S-100 card cage has a Z80 on it. -- David Betz DavidBetz(a)aol.com dbetz(a)xlisper.mv.com (603) 472-2389

Introduction

by rector＠christcom.net

Hello, I guess it's about time that I introduce myself. I've been lurking here for a month or better. I guess I really have not responded before because I didn't really have much to add especially to the discussions of late 70's stuff and the discussions of minis. My main interests (although I enjoy reading all of this) is the older systems based on the IBM-PC (XT & AT class) machines and PS/2s which I know is a bit more current than many of you like. I also have a Commodore 64 and Plus/4 and periphs, I guess I can qualify based on that. I really didn't start out to be a collector, but kind of fell into it. The Plus/4 was the first computer my family ever had, so I've now taken over the care and nurturing of it. I picked up my C64 a couple of years ago from my former minister who had is sitting in his closet. He had two 1541s, a MPS-803 printer, vicmodem, fast load cartrigde, joystick, and monitor, plus a ton of software. He wanted $30 for the lot after I enquired. I was in hog heaven but why wife rolled up her eyes and said "What are you going to do with THAT!" The XTs and PS/2s were give aways. I've really been having fun with the PS/2 Mod 60 (a 286 w/ one 1M and 40M HD). I have been watching AuctionWeb and have added pieces to bring it up to a '486 with 8 meg with SCSI periphs. One of the more interesting 'gives' I have since obtained is the Amstrad PC1512 - It's an XT class machine with built in joystick port in the keyboard (uses same joystick as C64), built it mouse port, serial and parrallel built in with the expansion slots going left to right rather than front to back. The power supply for the whole thing is in the monitor. The case has a 'cutout' for the the stand of the monitor to fit into. It also uses 4 AA bateries for the clock which are easily accessible (move the monitor). It is really a neat design. I live in Rochester, MN - so I'm not close to either coast (but Canada isn't that far away) Dan

Are they really common in some places and pretty >rare in others? As everyone says worth is a relative term, some computers that hvae high perceived values are given to people, etc. This is a question YOU have to answer as a collector, no one can set your price for you. Well alot of the PETS were purchased by schools and some businesses, prices for the computer back then when they were new (1977-1981) ranged >from $700-$1,200, disk drives were about $1,000 for a dual drive model. Nowadays in my region of California schools have been ridding themselves of them at a high rate. The computers are not too terribly hard to come by but the drives are harder to find. Rarity? Hmm, probably the most interesting is the original series with it's colorful calculator-style keyboard (circa 1977) and in-case cassette unit. Next I would say is the SuperPET (circa 1981, the last of the line, which I described about two digests ago) with it's mainframe-friendly, multi-language ability. All units had monochrome displays and either 40x25 or 80x25 screens (no hi-res graphics without 3rd party hardware), the BASIC is almost exacly the same as in the Commodore 64 or VIC-20 and uses a 6502 processor. Memory ranged from the first 4k units (a short run), 8k, 16k and 32k with some of the latter 80 column machines sporting 96k expansion bnoards. There are a few collections of programs available on the internet with most still to be re-discovered. >The ones I have seen are pretty cool looking in a retro-future kind of way. That's true, back then they 'looked' like a modern computer, more than some of the other computers (which looked like the steel boxes they were in). You can spot them as props in movies now and again (Star Trek II, in Kirk's apartment). They were fun, and they were pretty good even for their limitations. If you are a fan of Commodore computers it is a nice addition to have some PETs in the house. ;) >Also note that whois reports that efni.com is in Canada. The machine >might not be in Australia. Commodore was pretty big for a good while in other countries as they had the foresight to start manufacturing plants internationally (Germany was probably one of its largest). As far as shipping a PET it would require a very sturdy box about the size needed for a 19" television and would weigh 30 to 40 pounds. -- Larry Anderson -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Visit our web page at: http://www.goldrush.com/~foxnhare/ Call our BBS (Silicon Realms BBS 300-2400 baud) at: (209) 754-1363 -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

apple II - SCORE!

by thedm＠sunflower.com

I use alcohol, windex, fingernail paint remover and other noxious things to clean apple][ cases, just avoid getting the nastiest of these solvents on things like the little lite that says power, or the apple ][ logos on monitors or the name badge at the top of the machine. I've also heard that some people will dissasemble the computer leaving the empty shell, take out EVERYTHING, and run the plastic case through the dishwasher, not using the Heated drying cycle of course. As for key repair, they are little plastic wedges that are shoved against two vertically mounted contacts, counter forced by a small spring. You can not remove the keys without damage. To repair a keyboard you have two options, One, Replace the entire keyboard, or aquire a ][ for parts and remove the keyboard from the unit, the contacts are soldered into the keyboard cirucuit board. You can then replace the switch. The Key caps can be removed. but you can't get to the switch of course without destroying it, or desoldering it as a unit. I have manually recontructed them before, but they never seem to work quite right once forced open, but the do function enough to use as long as it's not an alpha charcter, or god forbid the enter key. ---------- > From: J.

Apple ][ design (was: Bad feelings)

by BROBSTONA＠wartburg.edu

>I can understand why the Apple ][ has a significant following - it was a >machine that was 'open', that hackers could get inside, etc. But I also >know that it's not a good piece of hardware design, and thus don't put it >high up my list of interesting machines. Perhaps I am merely biased from growing up with the Apple ][ at school and, later, at home, but I would say that some of the design is ingenious. I do know that many a programmer has complained about the arrangement of the high-resolution screen in memory (which was arranged the way it is to save components). But, I find the economy of this feature fascinating. The Apple ][ and its successors had great capabilities for expansion (with the possible exception of the IIc and IIc+). A IIe has the capability of using a hand-held scanner, for instance, with the right slot card and the right software. I'm sure the IIe wasn't designed originally for that task. There are numerous other examples as well. Your mileage may vary, of course. -- Andy Brobston brobstona(a)wartburg.edu ***NEW URL BELOW*** http://www.wartburg.edu/people/docs/personalPages/BrobstonA/home.html My opinions do not necessarily reflect the opinions of Wartburg College as a whole.

Apple ][ design (was: Bad feelings)

by allisonp＠world.std.com

I never thought much of the apple design save for it was there and successful by the only standard that counts...they sold like hotcakes. It's not a technical judgement as that really didn't count! there were some machines I considered poor, TRS-80-M1, at a time when z80 was minimally 2mhz and many pushing 2.5 it plodded at 1.7, but it was a complete machine for much less than many of it's kind and available through a nationally known store. Price vs performance _and_ popularity drove a market not real technology. If it was useable and met the current market expectations it sold well. If there was one significant impact apple made it was in the idea of low cost software. Apples were not the home of $350 basic interpreters or $500 compilers. But at one time I counted not less that 5 distictly different OSs. Some were pretty poor but the drive to improve the beast was there. Allison

Shipping Abroad, bla, bla, bla

by gmast＠polymail.cpunix.calpoly.edu

Thought I would toss out some of my experiences with shipping out of the country. I've sold a few items to various people in other countries (not all computer stuff though). Only problem I've had was waiting for payment. Sometimes it's not sent, sometimes it get's lost. The buyer covers shipping and any taxes/duty when they get delivery. Japan: I sold a couple old Apples as I think they're pretty popular for collectibles there. Hard to find. Some people I sold to were US citizens living there. Shipping is cheapest via USPS slow boat and the customs paperwork is one small form. Australia: Sold some small stuff. Payment arrived faster than most US mail. Shipping is cheap for under 4 lbs "small packets" via USPS and again Customs is a piece of cake. Europe: Austria, Italy. They seem to have a problem with the mail. I sold some cheaper stuff so the buyer sent a money order - lost. Then he sent cash - lost. Ended up wiring the money. According to him he sent out 12 payments at one time and 5 never arrived at the destination. I'd say wiring money is better. Again customs is easy. USPS tells you what to fill out. Canada: Piece of cake. Just be honest on the contents/value. Guam: Shipping is really cheap because its serviced by USPS. Like mailing within the continental US! There was some controversy a while back about exporting collectibles. Supposedly you could buy a concours collector's car for $20k, ship it to europe or Japan and sell it for $50k. Some collectors thought this was treason or something. I really don't know. What I usually sell doesn't fall into any "rare" category and most of it was sold all over the world anyway, just in lesser quantities or slightly different versions. One guy I sold to was in the US. I asked him why he was buying a pile of old Apples, he was putting together complete systems and shipping them to Japan. Funny, Apple had/has a ton of manufacturing in Japan. I wonder if they limit sales there.

A friend build one about 6 months later and it was still flakey as hell. First of many mods was to get the damm oneshots off the cpu card and put in a 8224 clock generator. I got mine to a stable state but when the S4K memories came out I upgraded asap. Better but far >from great. To many oneshots. In late '78 I transfered my IO, NS* MDS to a new HORIZON box with a 4mhz z80. used the altair for a few years to support testing (front pannel). I put it in mothballs about 84 and will likely never use it again. To highly modified to even consider museum piece and in '79 it suffered a lightining hit and was never right since. Allison

A little guidance - TI Xenix

by danjo＠xnet.com

I realize this is a little off-topic (last build was about 1987 or 88) but I have my self in a corner 8-) There are a couple of windows I could crawl thru if I HAD to. I have a pristene TI Xenix 386DX16 system. I have access to one account and - you guessed it - it ain't root! Nobody seems to remember the root password 8-( I can't believe that I can't break into this thing! I don't have the original disks (I haven't dug that far into ALL my docs) but it has a SCSI Tape drive and two 8 port serial adaptors and some *special* TI card. It has 2 140 MB MFM drives and I want to keep both the drivers for the multiport boards and the SCSI board. I think I can get it to run Linux but I *really* don't want to blow away the Xenix. So - does any body know where I can find a way into Xenix? Are there any archives of CERT Advisories on glaring holes I can worm my way into editing the passwd file or something? I realize I could run CRACK but since that isn't what I normally do for FUN I was hoping the mass intellegence and huge experience in this list might be able to help 8-) All suggestions are welcome - except blowing it away.

Why?

by e.tedeschi＠ndirect.co.uk

What's wrong with this (virtual) "group" ??? Of all the collecting groups I belong to, this is the only one where my (and I suppose other's) public (and private) requests for help have been ignored and (worse) I suspect even opposed. Is there something I don't know? If this the case I would like to know. Thank you. Also your caper to insist on having ALL the items in the collection in working condition is, in my opinion, unique to this group. I can understand (and share) the motivation but surely we (I?) collect for the design point of view and for the historical importance. Don't we? Or am I in the wrong group anyway? Sorry for the frankness but I thought I'd get this one out of my chest before it gets even worse (I am still owed at least 5 replies to my messages) in that I will be banned from this mailing list. Hope not. What is your problem?

This weekend's haul

by zmerch＠northernway.net

Due to massive amounts of caffeine & sleep deprivation, Doug Spence said: >Does the PS/2 not have any 5.25" drive bays? Weird. :) I'm not an IBMer >so I don't know these things, though I *think* one of the machines I used >to do CAD work on was a PS/2 of some flavour. Every PS/2 that I've ever seen (note: this does not mean All PS/2's... just the ones I've seen) didn't have a 5.25" port at all... not even their tower "servers". I suspect it was IBM (trying to) setting a new standard... again. >OK, that makes it useful.

IIRC, it's just straight thru with the last/first 3 pins unused... but I'd have to look at the cable or ring some pins to be sure (and yes, I'm a packrat...). I also believe that you can still get 37-pin D-sub connectors thru the Mouser Electronics catalog. Good people to work with... I had 3 distinct problems with my first order (totalling $40USD) and they took care of all of them at their expense (shipped some closeout SMD resistors *overnight* because they forgot them in the package... their expense... that's their policy, despite my not being in a rush for them!) Try http://www.mouser.com . >Interesting. How are the drives interfaced to the CoCos? I've got a >CoCo1, CoCo2, and CoCo3, but I've never found a disk drive for these >machines. All CoCo controllers take Shugart standard drives (now called IBM standard drives... IBM's taking over again!) altho RSDOS limits you to 35 tracks, SSDD, 156K disks (the original Shugart drives) without patches... which (of course) I have. RSDOS can handle a max of 2 DSDD 80 track drives with patches (more accurately... they look like 4 SSDD 80 track drives, with :2 the backside of :0 and :3 the backside of :1) but 1.44Meg storage thru RSDOS is really good!

There are three ways to get into the case, only one of which I recommend. The first method involves a chainsaw and a 12lb (5.5kg) sledgehammer... If you have to ask, you don't want to know. ;^> The second method would require an appropriately sized Torx screwdriver and a Dremel tool with drill press attachment. You would need to drill a small hole in the end of the Torx driver to accommodate the post in the screw. While this method is the safest to the drive, it's also the most work. Method 3 (which is the one I used) requires a pointed instrument (like a leather awl) and a regular (flat-head or slotted) screwdriver that just fit's into 2 of the points of the Torx screw (the screwdriver tip of my tiny Swiss Army knife worked perfectly). Use the awl to bend the post over as much as you can, and this *should* (no guarantees, YMMV, yadda, yadda, yadda...) get you enough room to get enough of the slotted screwdriver into 2 of the star points and extract the screw. As the case is built like a Sherman Tank, once the screws are removed, deep six them. I've been running mine for 3 years without the special screws with no ill effects. Anyway, I hope this helps, and enjoy the drive!

CoCo Kits

by jrice＠texoma.net

I have an unusual CoCo 2...it was produced as a kit form. I bought it at a RS tent sale in Dallas in 1985-86. I thought it was a plug in the boards kit, but when I got it home it was totally bare boards. Took several hours of soldering to complete. I was told by a friend who was a RS manager, that they were a pilot program for schools to have classes assemble the machines and then the school would have alow cost path to getting more computers. Tandy later decided that this would be a warranty nightmare and sold the kits for $20 at the tent sale.

Label Remover

by ard12＠eng.cam.ac.uk

There was a thread here a few weeks back about dealing with those sticky labels that seem to accumulate on classic computers. I've just bought a can of a substance called 'Electrolube (the brand name) Label Remover'. You spray it on, wait a few minutes, and rub the label off. I used it yesterday to remove some _strong_ double-sided adhesive tape inside my laser printer, and it did the job extremely well. The can claims that it may attack some plastics (so take care on classic micro cases!), and it's not that cheap (\pounds 4.00 for a small-ish spraycan from Maplin). But it certainly does the job. -- -tony ard12(a)eng.cam.ac.uk The gates in my computer are AND,OR and NOT, not Bill

AIM65

by bwit＠pobox.com

Sam, Thanks for your efforts in the great AIM-65 buyout! I'll take two of the Panasonics. Regards, Bob ---------- From: Sam Ismail[SMTP:dastar@crl.com] Sent: Sunday, June 22, 1997 4:18 AM To: Discussion re-collecting of classic computers Subject: AIM65 Ok, here it is. Mike Westerfield, the guy with the AIM65s, phoned me yesterday and we spoke about the deal. He has been offered $125 for EACH unit from a company called Dynatem which still uses the AIMs commercially. Mike started a company way back with a product based on the AIM65. It was an insurance rate calculator. In order to make the product marketable, he designed a plastic and a metal-base enclosure. He also placed a compact power supply inside the enclosure to make for a nice complete package. He apparently was very successful with this venture and sold many. At this point, unless someone comes along and offers him more than $125 per unit and buys the whole lot, they are going to Dynatem. That's too rich for my blood. After explaining all this to me, and after I explained what we do here on classiccmp, Mike mentioned that he had a bunch of other stuff that we might be interested in. He has a whole basement full of stuff he would like to sell off. Here's what he told me he has: EPROM burners Logical Devices GangPro-S and GangPro-2S. These can burn 32 chips at a time. These also have other features which make them very nice. Logical Devices GangPro-8 and GangPro-4 which can burn 8 and 4 respectively. Optical Technologies EP-2A-88 and EP-2A-89. EPROMs A "ton" of NEC-2716 and Hitachi 2716 EPROMs He also has the line on hundreds of Panasonic RL-H18 palmtops. This is a palmtop which came out around 1985 and had FORTH in ROM. It also has a 20-col (or 40-col?) thermal printer and a case which bundles the two together. His company also developed an expansion "tray" which houses extra memory that the Panasonic can access through bank-switching. He sold this product to (I believe) an insurance firm and now they want to dump them all. Now again, he said they have hundreds, and were just going to shit-can them, but he said the company would most likely opt to get some money back for them if they could. He said probably about $10 per unit would get them, but they'd have to be purchased in one shot. Now I don't think that there are enough people here with an interest to buy one. I suggested that perhaps they can set aside a couple hundred and then shitcan the rest because I don't have a couple thousand lying around in which to buy all of them, nor would I want to. It's up to us to come up with a proposal. As far as dealing with Mike, I asked him contacting him. At this point, he would perfer the current arrangement whereby I am the central point of contact because it is easier for him. However, this tends to put me in a bad spot for certain reasons. I'm sure there will be people interested in working out a bulk deal with him. To those people I say feel free to contact him since he is most interested in getting rid of everything in one shot. He's not interested in dealing with onesies and twosies. So he would like for everyone who has an interest in a little here and a little there to contact me about it and then he's going to call me again in a week. This would refer mainly to someone wanting one of the panasonic's or a few EPROMs. As far as the Panasonics, he's finding out more information about quantity and we will talk more about price next week. As far as the EPROM burners, I would think that dealing directly with him would be best. Anyway, his e-mail address is Mikeooo1(a)aol.com. He's a very nice guy. He offered that if there was anyone in New Jersey (I believe there is at least one person here, I can't remember his name) to come on down to his place and he'll show you through all the stuff he has.

Some computers are so classic that they're still out there doing Real Work! I am going to have to pull my other AIM65 out and take a good look at it to see if I can figure out who badge-engineered it. (I wonder if it was Mike?) It is also in a plastic case that is obviously intended to make it portable, and I wonder how many other companies there were doing specialized applications around them. Thanks, Sam and Marvin, for sounding this out and being the go-betweens. -Frank McConnell

The problem lies in the fact that in the early/mid 80's Dynatem *bought* the rights to the AIM-65. Lock stock and barrel. I guess they have a right to buy them. I don't think they are going to get tossed anytime soon. I might try to contact them and maybe buy one of of them. BC

Unlike Altair and Imsai, PETs are obtainable here. I have one chicklet keyboard 4k version, a CBM 3032 and a CBM 8032 hulk. I suspect they will always be around because they are so hard to destroy. The case is very solid. I found the "hulk" in a paddock, like some people find ancient cars! I've never attempted to power this one up though.

I would be glad to help you with it. There is the matter of customs which many americans have little experience with. I sent a floppy to someone in canada and despite it being our neighbor the customs paper was amazing! I was told it's worse if there is a transaction involved. Allison

>Actually a 8ksram and a 8kprom would do it. Actualy what I had in mind was for the EPROM to copy itself into RAM and then switch itself out.

Printers and Finds of the Week

I recently found a Sears Roebuck & Company SR3000, which is oddly enough a RGB/Composite monitor made for the commodore line? Who knows. It even has a speaker in it! Picture is really nice. Made around the same date! Got it for only $10! If I don't use it for an old computer, it is a great way to view the camcorder stuff! Josh M.

Saturday's Finds and a source in Central CA

by foxnhare＠goldrush.com

I finally attended a almost 'near-by' used computer store's "warehouse sale" and was somewhat impressed. The sale is held Saturday mornings in an old nursery greenhouse about 5 miles east of Lodi on Highway 12 (in California) Almost every table is covered with equipment, a good portion seems to be discards from local school districts and others are from who knows where. The good and bad news is much of it has had some share of the elements and are sold as-is, but they are priced to clear. (they were not "out in the open" like some machines you have reported, but almost). The store keeps most of the more-modern usable stuff (PC cards, motherboards, printers, etc.) and leaves behind a lot of Commodore PETs, 64s, Apples, old PCs, etc. Must have seen about 1/2 dozen apple ///s in varying states, even more apple ][s, (from some ][ pluses to a Platinum ][e w/keypad and a couple ][cs), plenty of drives (1541, apple and old hard drives; looking for an older hard drive? make a 'look for' list ready). Lots of monitors (condition unknown as many were from a repair shop that closed; also alot of composite Commodore monitors - 1702s and CM141s). Many PC enclosures (not my area so I didn't look too hard, did see look at a Commodore PC clone though (figures), motherboard still there, but no cards or drives, some older pulled cards in boxes. I did notice at least three Osborne computers, the one I opened to look at was a later model as it didn't have that tiny screen in the center but what looked like an 8" display. Bunch of Jasmine Hard Disk cases (external, backpacks, and clip-on drives) and such for people needing power/cases for projects (some with drives still in em). Also various cables (bunch of IEEE-488), power supplies (commodore 64 was in abundance) some books and other micellany. I didn't see any minis there, but you never know... We came out with: - Educator 64 (a Commodore 64 in a PET enclosure w/monochrome 14" display) computer is dead but it uses a standard 64, so no problem there. ;> - Commodore LP2031 PET/CBM IEEE-488 single drive (a IEEE-488 drive in a 1541 case) seems to be ill but much of the electonics and all mechanicals match the 41, no problem! - Jasmine Removable 45 drive (I am assuming a Syquest 44mb drive, it looks similar) still have to get a cartridge to test, but seems clean and ok. - Commodore 1541-II w/power supply & cable (so far so good) - C= Brick Power Supply (light colored one. still untested) - Sea Wolf & Clowns cartridges for the VIC-20. - 'Commodore' paddles and 'Commodore' joystick - An AC 'muffin' fan (works, now cooling the BBS!) - 6 Commodore books (including three nifty Hofhacker ones published by Elcomp) I left a whole bunch of other VIC & 64 books behind cost $30.00 (I could have walked out with more for the same price, but I was being good) Warehouse Sale: 10400 Highway 12, about 5 miles east of Lodi, 8 am to Noon on Saturdays (if you do go, let them klnow that Larry, the Commodore guy told ya about it!) The computer place is: Allen's To Go, in Lockeford, (209) 727-0477 -- I picked up at a couple thrifts some (soon to be) blank disks, the prices are cheaper than MEI/Micro's bulk pricing, $1 for a box of 10+ 5.25" DS/DD...

Printers and Finds of the WeekFrom: Sam Ismail <dastar@crl.com> To: Classic Computer Discussion <classiccmp@u.washington.edu>

by foxnhare＠goldrush.com

References: <199706150702.AAA14700(a)lists3.u.washington.edu> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit RE Printers... Gorilla Banana, Tandy DMP 100, Commodore 1525, etc. It was a standard printer mechanism by some manufacturer (I suspect Shikosha (sp)) All were 7 pin characters. I remember some early Commodore Printers (before the 1525) were Epson units (one based in the MX70?) I also remember, for the PETs, our school had a SWTP dot matrix printer. Pretty nifty little bugger, no fancy coverings, you got to see all the gears (printed on 4" wide roll paper as I recall) liked like an early ticker machine or something like that. They also had a Commodore 4023 and a Diablo 630 (heavy as heck and made quite a racket too). I have owned a couple curiosities such as the Commodore 1520 printer plotter (another model type that bore through many company brands) four little tiny pens. Made neat sounds when it was drawing text and lines. :) I still have my Citizen iDP560cd printer, prints on wide register tape (2.?? inches) in two colors (Black/Red) has a Commodore interface and all that. (nowadays you usually see that model printer -w/parallel interface- hooked up to merchant ATM units). Other now gone units MPS-801 and Star NP-10. Other (classic) printers I now have are a Riteman F+ (precursor to the ProWriter Jr.) it has a very short ribbon (something like 20") but a unique feed system (able to print on index cards and use the first line of a page...). Everything else is somewhat modern late model dot-matrix and ink jets. Oh, and a Commodore 8023 wide-carriage dot matrix for my PETs. ------------- RE: Sam Ismail <dastar(a)crl.com> Subject: Beat this haul... >Ok, the weekend's not even over, and here's how I did: [snip!} >Commodore 64, Commodore 64C (two of 'em, one seems to be this weird clone >since the plastic looks different from the other one and it has no >markings) It's probably an older 64 in that slimline case that was selling a few years back to make an older 64 more resemble a 64C. I recall the ads in Compute's Gazzette and RUN. *** light applause *** that certainly was a haul as well as a good little adventure! Thanks for sharing it with us. :) I know of a Salvation Army in Oakdale that has a small basket full of TI carts including some nice AtariSoft titles... ;) Next time when I get there (and if they are there and are cheap enough) I'll pick some up. --------- Now for my haul (which was today, Sunday). At the Flea Market: 2 Atari Power Packs (15.3va and 31 va) $3.00 now all I need is some Atari DOS and utility disks (HINT! HINT!) 1 Commodore 64C power supply $1.00 a couple printer switchboxes $1.00 ea. Toshiba external SCSI CD-ROM drive (seems to be partially working) $3.00 14.4 Modem $2.00 External Amiga Drive $1.00 At the Thrift Store: Commodore SuperPET (Gosh was I lucky) $20.00 (w/Wordpro plus quick referencebooklet, PET to IEEE-488 cable, power cord and "the Manager" dongle still attached) Commodore 4040 Dual Drive $5.00 3 IEEE-488 cables $2.00 each The SuperPET isn't responding, but still worth it, (I cracked it open to see the guts, there are two daughterboards connected to the motherboard the topmost seems to be the RAM (which makes the computer 96k), and I assume below that is the 6809 co-processor and RS-232 driver. Now I have to hunt down more information... :) Four toggle switches peek out on the side which allow for the storing of the language you wish to use, (setting it to ROM mode did not seem to change the situation) Have yet to test the 4040, I hope it is functional. So far everything from the Flea Market seems to work (I have yet to test the 64 supply though). Nice day, though I think my checkbook is feeling a little thin...
