I can't believe you have Nova 1200's. I used a 1220 in the late 70's in high school and it was old then. Ours actually had a hard drive which was about 36" on a side, covered with woodgrain vinyl, with a capacity of a MEGABYTE!! I might still have the source to my Nova multiuser Star Trek around someplace. It was so popular it got banned from the system since it slowed everything down too much.

Wanted Systems

by carl.friend＠stoneweb.com

I've seen a certain amount of conversation as to the appropriateness of "For Sale" messages on the list. So long as it doesn't get out of hand, some of the posts can be quite useful (like the one on IMSAI switches, for instance). How about "Wanted Systems" posts? I'm looking to flesh out my collection of 16-bit Data General hardware, and am looking for leads to systems, or systems themselves. Anything in the Nova/Eclipse line is fair game, with the exception of the 32-bit MV series (although I hope somebody is preserving them!). Any documentation is, of course, more than welcome.

It's true! (Also, Acetronic/Radofin Video Games)

by alexios＠vennea.demon.co.uk

Ok, I admit it. You really *can* find more stuff these few weeks. I went to car boot sale today and got three machines (five, were I willing to shell out for two C64Cs with a floppy drive and a PSU between them). I'm not the proud owner of a Spectrum 48k (at last!) in mint condition and a Spectrum +2A in even better shape. I actually got the +2A at half the price of the 48k -- 5 pounds for the +2A (around $7? Not sure) as opposed to 10 pounds for the 48k. There was another +2A for sale at the outrageous price of 15 pounds (at least I *hope* I heard 15 -- at that noise level, it could have been -gasp- 50). Anyway, enough about the Spectra (sic). :-) There's another find I might need a little help with. It's not strictly a computer, it's a video game (Video Entertainment System, as it says on the front panel). Specifically, an Acetronic MPU-1000. The PCB has a Radofin label on it. There are two analog joysticks with two red fire buttons and a 12 button keypad each. They're connected to the unit with spiral cable (no plugs). The controllers are designed to take overlays to give meaning to the 12 unmarked keys. I don't have any overlays, but there are four carts: Invaders, cart #1 (Olympics -- actually a more or less standard set of Pong-like games), cart #11 (Super Maze -- remember A-Maze-ing on the TI? It's very similar. Analogue control of the players is quite tricky), and cart #13 (Circus -- I haven't figured this one out yet due to the erratic behaviour of one of the controllers [read: vertical axis doesn't work properly, fire button won't]). The cartridges claim to be "suitable for Acetronic, Radofin 1292 & Prinztronic microprocessor systems". Does anyone have any ideas about this? Is it common or uncommon? The name Radofin was familiar, after a bit of research it turns out it's the company that bought the rights to the Aquarius. Any technical information would be welcome, since I can't identify either of the LSI ICs on the PCB (yes, two of them). Oh, by the way, in the highly unlikely case this is amazingly rare and the only one left on the planet (unlikely because at least another person on the WWW has one, albeit an MPU-2000), I obtained this at the silly price of 2 UK pounds. The previous owners seemed a bit amazed at the fact that someone might actually be *INTERESTED* in that piece of junk. Can't complain, really. :-) Thanks, Alexios --------------------------- ,o88,o888o,,o888o. ------------------------------- Alexios Chouchoulas '88 ,88' ,88' alexios(a)vennea.demon.co.uk The Unpronouncable One ,o88oooo88ooooo88oo, axc(a)dcs.ed.ac.uk

How long will they last?

What are some other concerns >along these lines. What should we be planning >for as these machines grow 5, 10, 15 years older? Good questions all, so some comments and some thoughts. EPROMS: yes, they will forget. Being stored charge devices they will eventually start to lose the stored information. As I recall the original estimated life for stored data was 10-15 years. Punched tape (mylar preferably or paper if stored properly) may be the closest thing we have to a true "archival" medium. Electrolytic Capacitors: They dry out, or will start to ooze the electrolyte. (I address this to some extent on the 'Repair Tips & Tricks' section on my web pages) Average lifetime (of large caps such as found in power supplies) is probably 5-10 years. On machines that I restore they are (almost) always replaced before I do anything else. The very small caps found on logic boards for timing and similar circuits do not seem to be a prone to failure. Disks: depends highly on how they are stored. Should be treated similar to records. (remember those?) Store upright, loosely packed, dry but cool. Watch for oxide flaking on very old disks. Tapes: similar to disks for storage. Should be retensioned (repacked?) >from time to time. (fast forward to end, then rewind) As with disks, watch for oxide flaking. Dampness will cause some tapes to adhere to itself, and strip off the oxide when run. Had this happen to my "Standard Pack" tape for an HP-85 I obtained recently. Went to load the tape and got a read error. Manual inspection of the tape showed a 3/4 inch strip where there was no oxide at all. it was stripped away by the tape adhesion when I rewound the tape for probably the first time in 4-5 years! Card edge connectors: corrosion is common, expecially is stored in damp places or contaminated by skin oils. Can be cleaned with the classic "Pink Pearl" eraser. (Don't use the grey erasers - too abrasive!) Hmmm... probably more, but it's late and I forget... (often it seems - bad EPROM?) More later... -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

New ATARI 1040ST user needs help...

The 1040ST is a nice system, but you'll need to find one of the Atari monitors for it, such as the SM-124 (very nice mono) or the SC-1224 (color). You don't need an OS disks for it, as the OS is built into ROM, and it uses standard PC 720k disks. For software and such, Toad Computers in Severna, MD is a good resource..and they even sell TOS upgrades and refurb monitors. Atari's have been their specialty for years. Hope this helps.

Digital Microsystems DMS-3F, DEC Rainbow, TS 1000

by Bill_Opalka.INTDATA＠notes.intdata.com

I was under the impression that it was ok as long as it's not excessive. I even mentioned it in my introduction message and have seen it discussed a couple times. I believe this was my first post of this type. I don't want to make any enemies here. Sorry for any inconvenience. Greg
