Manual for the Overland Data OD3201 Tape Drive?

by marc.verdiell＠gmail.com

I know what you mean. There were two awesome CDC 609 available semi locally recently. Carl and I fantasized to pick them up. When we looked at the weight, clearer mind prevailed and we gave up. Not sure what happened to them. Marc ================================================ Subject: Re: Manual for the Overland Data OD3201 Tape Drive? My favorite drive is/are the CDC 607/609. Wonderful units--1500 lbs., IIRC. At any rate, you wouldn't want one to fall on you. Less so the 65x and 66x drives. --Chuck

cctalk Digest, Vol 16, Issue 7

by marc.verdiell＠gmail.com

I used John's routine to write and Chuck's to read an HP 1000 SIMH tape image, and the file diff came out identical, give or take a few end characters that I don't believe are part of the data. So you guys are essentially compatible as expected (16 bit machine it sure is).

It ain't from DEC, for sure. FWIW, my routines don't bother to pad to an even byte boundary. --Chuck

IBM terminals last call

by sales＠elecplus.com

Today they start getting cut up if no one responds. 3472 and 3477 terminals, keyboards, printers, etc. 12 pallets total. The terminals are coax. Maybe 100 of them. Keyboards are 122 key, prob abt 150 of them, most have cables. Some are RJ45 and some 5-pin DIN. Yes, you can go look, if you want 10 or more of something. No, he won't ship individual units. Located in WI. Email me off list if you seriously want to go buy. Cindy --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

server for terminals

by sales＠elecplus.com

I did ask, and he said there is nothing labeled 360 or 390 or any server-looking cabinet, nor anything waist tall except the line printers, and nothing that looks like a computational device except the 3174-11R, of which there are 3. If there is something else to ask, please let me know. Cindy --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Looking for RX01/02 rack slides

by ball.of.john＠gmail.com

>> I actually need some slides for my RL02... Are these the same type? >Nope. DIGITAL designed their own chassis slides after the 11/34 >11/44, RLxx and everything after were custom. I think at that point there I'd wander down to the local computer recycling center, buy a set of suitable rails and mount a new set on with self-tapping screws once you checked your clearances. It's what I did to my 11/84, RA82 and Cipher drives. -John

Manual for the Overland Data OD3201 Tape Drive?

>I've got a bunch of files that are Overland 32xx-related, but I don't >know if they'll be useful. I don't recall where I got them off the web, >but I'll be happy to forward them along. Probably close to 75MB worth. Thanks, I?ll gladly take all of it. Email away, or if you can share on a web folder such as a Dropbox I can grab it. Jim Cimmeri also sent me some relevant files, thanks Jim. >I don't care much for the Overland desktop drives, due to the chassis >being constructed largely of plastic. Mine might be a different drive. Tower model, pretty slick design. Seems well constructed, out of metal (I think!), no foam inside the door. And nice locking door too. Very silent, easy to load. Like this one on e-bay right now: http://www.ebay.com/itm/RARE-VINTAGE-OVERLAND-DATA-STORAGE-TRACK-DRIVE-MODE L-OD3201-/252096228767?hash=item3ab21b2d9f I like it better than my Qualstars. But then again, I haven?t yet met a 9-track tape I didn?t like ;-). My favorites so far are the 729 7-track tapes we have on the IBM 1401. Nothing beats a 1000 lbs, 112.5 inch/second vacuum column drive :-) !

Spare Time Gizmos Life game LED tool

by dave＠661.org

I've acquired an unpopulated board for a Spare Time Gizmos Life game. Does anyone here who've made one still have an LED tool you don't need that you can pass along. How about a design file for making one myself? I tried asking this on the Spare Time Gizmos list and nobody replied. -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Compaq Portable II - IDE compatibility (and setup disk image)

by jules.richardson99＠gmail.com

My Portable II uses a Miniscribe ST506/412 drive hooked up to a bridge board that I'm told is IDE at the other side, back to the controller. The original drive in my machine is toast - I had to pop the lid to free the spindle. It spins up now, and might cough up some data (for a while), so intention is two-fold: 1) Put the original drive and bridge board into a more modern system to attempt a read, 2) Replace the original drive/bridge combo with a more modern IDE drive (happy to waste 99% of the space on it...) Are there any gotchas involved to either of these, given that IDE was presumably in its infancy when the system was current, and so its possibly a slightly different animal to a more modern version? I don't want to fry the Compaq's controller, or the bridge board. In addition to this, the machine's lost its config, so currently defaults to a floppy boot. Does anyone happen to have an image of the 360K setup floppy, either in Imagedisk or raw format? (LLF is presumably 512 byte sectors, 9 sectors/track, and 40 tracks per side?) cheers Jules

This is sad...

Well, I agree, sometimes the machine is disassmbled in a way that harms the components, or vital components are thrown away/re-cycled because 'they don't seem like they are useful/valuable' (case in point, cables - people save the boards, and throw away the cables - as a result of which, for many boards, we have more boards than we need, and no cables). On the other hand, if this stuff _wasn't_ worth money, most people would just re-cycle it, or pitch it. That would be better? Noel

A VIC-20 IEEE Project

by silent700＠gmail.com

Some friends in the local 8-bit micro hobby have whipped up a clone of Commodore's VIC-1112 IEEE interface for the VIC-20 computer. The news has probably permeated most of the C= scene but I figured it was worth dropping here for maximum exposure. I saw the prototype working at VCF Midwest earlier this year. They're funding it through Kickstarter and have reached their goal, so production is sure to go ahead. You've got your choice of a DiY board, assembled board or a fully cased cartridge. Just over 60 hours to go: https://www.kickstarter.com/projects/1203958506/vic-20-ieee-interface -j
