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

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.

Classsic Computing Newsgroup revisited

by foxnhare＠goldrush.com

About a month or two back we were discussing starting a newsgroup for classic computer collectors. I just wanted to mention there is a somewhat related newsgroup on the net that could use some activity: alt.technology.obsolete I am for it, I have it on my news sites to check and in the last few months I have maybe seen three messages in it (two being multi-newsgroup spams) Whaddya guys (and gals) think?
