Was someone looking for an Atari power supply? I have one for the 400/800. Output 9V AC, 31 VA. I don't have any Atari computers left so whoever wants it it's $7 including postage. Greg

Osborne 1 prices (was: On Generations of People and Computers )

by ronaldm＠mars.ark.com

I have an Apple II Plus, with 4 (count 'em) 4, 128k disk drives, all operational. It also has a 256k RAM card, an 80 col card, and a Super Serial card along with a Microsoft Z80 CP/M card. I don't use it very much these days, except for a bit of record keeping on my video tape collection. Just out of sheer perversity, I'm using Appleworks, which loads itself into the RAM card and seems to operate from there. Also have something called the DAVEX shell, which provides a front end for a number of activities including running Appleworks. Once you get the <ESCAPE-DO THIS-DO-THAT> keys figured out, it works not half bad for my occasional record keeping. It's like most of the stuff I have around here. It came with a literal ton of software, most of which I haven't even taken the time to check out yet. Also has a voice recognition card, and an EPROM burner which are sadly stored away in my lockup. One of these days. So many computers, so little time! -Ron Mitchell ---------- > From: Tim Shoppa <shoppa(a)alph02.triumf.ca> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Osborne 1 prices (was: On Generations of People and Computers ) > Date: Saturday, April 26, 1997 12:52 PM > > > > I just swapped a bare II/E for a Bare II.

Funky looking mouse and other TCF stuff...

by more＠camlaw.rutgers.edu

Hi guys, just wanted to say what I got at TCF. I managed to get there at 3:45 on Sunday (15 minutes before closing on the last day of the show.) Anyway here's what I got: 2 Seagate MFM Hard Drives *FREE* 1 Sysquest tape(?) drive *FREE* the tape drive is about the size of a CD-ROM, what is it? 1 Apple IIe Users Guide *FREE* (why? I dunno, it was in the trash) 1 CBM 8032 $5 (this things got some kind of memory board that plugs into the CPU socket and a parallel interface) 1 Funky Mouse *FREE* This last thing I need help with. It looks to be about 20+ years old but I could be wrong... It is bright red, almost perfectly round, has a steel ball as the roller, 3 black switches, and says "5271" and then "DEPRAZ - MOUSE" on the bottom. It has what looks likea standard serial cable. The guy said it was for a terminal right before he threw it out. Any ideas? More importantly.... do you think I could use it on my PeeCEE? 8) Les PS what'd everyone else get at TCF?

The List!

Ward, The Model 2000 did carry the TRS-80 logo. The black/silver badge on the front of the machine, which was rotatable in case you put the 2000 upright on it's nifty floor stand, said 'Tandy' on the first line, in a black band, 'TRS-80' on the second in a silver band, and 'Model 2000 Personal Computer' in the third on another black band. This is clearly shown on the front of the 'Tandy Service Manual: Tandy Model 2000 Personal Computer'. I owned one of these machines for a number of years, but sold it when I got caught in the clone upgrade mania. Now I'm working on purchasing another. Also, I aquired an Atari XE System today, with the optional keyboard, along with two 1050 disk drives. Cute little machine, and includes the light gun. Anyone in need of a 1050 disk drive for an Atari 8bit? I don't need both, and don't have a PSU to test either out with.

At http://www.emulators.com the now have the schematics for their xformer cable on the web site, which should work with their xformer software, there is also a product called ape which is at http://www.nacs.net/~classics which allows you to connect your atari to a pc. They also have schematics and a program to run an atari disk with a pc, to copy and create disks. I have read a lot of flap about incompatibilities writing disks back and forth between the two types of drives. Of course, you could get a black box or an atr8000 and I think that would allow you to use a pc floppy with your atari. I have actually never tried any of these, I just use a null modem cable and transfer the software back and forth. Isaac Davis idavis(a)comland.com indavis(a)juno.com

ethernet and apple2GS

by jim＠calico.litterbox.com

As those of you who follow the comp.sys.apple2 groups know, there never was an ethernet board for the apple2, and the one that apple designed for the 2gs never went into large scale production. This annoys me, since the gs is certainly capable of running network applications - it comes >from the factory with appletalk/localtalk. So I've been thinking about this problem for a while. Before I go into my "solution", I should mention that I'm in no way an electronic engineer, and the odds of my even attempting to do this on my own, let alone succeeding, aren't very good. But it seemed like an idea at least worth sharing, on the grounds that maybe one of you who IS an engineer could make some bucks inventing this thing. My idea is this: build an ethernet board for the apple2 series with the following parameters: 1. it looks to the system exactly like a localtalk board, only faster. 2. it has enough brains to analyze outgoing frames to see if, in fact, what is being sent is ip encapsulated in appletalk. If so, de-encapsulate it and transmit it as straight IP. - this is a software issue, really, but it needs to happen in the firmware of the ethernet board, so... 3. It has enough brains to analyze incoming frames and determine if in fact the frame is an IP frame. If so, encapsulate it in appletalk and feed it to the system. 4. It has a way of turning all this brainpower off and being driven with a normal ethernet driver running on the host system. 5. It can do any translation between appletalk and ethertalk so the machine can talk to it's Macintosh kin. My reasoning for all the shenanigans with appletalk and ip is this: no standard mechanism exists for talking to an ethernet board in an apple2. However, the GS comes with atalk drivers in rom, and you can get them for earlier apples, and a lot of software does do tcp-ip over appletalk, assuming it's going to be talking to an appletalk/IP router downstream. Caviets: I haven't looked at the appletalk/ethertalk/localtalk protocol to make sure what I'm suggesting is sane. Same goes for tcp-ip over appletalk. There's a standard for this stuff, but I haven't looked it up yet. Anyway, that's my idea.

Non-micro classics

by carl.friend＠stoneweb.com

In the lengthy "Re: yo" thread, Mr. Ismail mentions: [double-quote from Mr. Donzelli] > > PDP-8, PDP-11, IBM S/3xx, Nova, etc. Computers were not invented in 1974, > > guys. > > Yes, I realized that. The PDP-8 and PDP-11 are definitely worthy of > mention, but did they really make the impact and have significance equal > to the Altair and the others? I'm sure you could argue to that effect. > Care to? It's probably fair to say the the minicomputer actually made more of an impact in society than the micro has. It was the minicomputer which was first affordable to smaller companies and operations; the mini was also the first class of machine available to schools of modest means. You'll find that almost every microcomputer designer was, at some point in time, touched by a mini, and sometimes their designs reflect that. One of the original Apple's designers actually held the DG Nova in such high esteem it's rumoured that he kept a picture of one taped to his bedroom wall. Billy Gates did the original work on his BASIC interpreter with stolen time on a PDP-10 (though, that can't really be termed a mini). Most of the impact, though, of the mini is behind the scenes; they made manufacturing more efficient through the increased use of CNC, made scientific experimentation more prodcutive through more accurate experiment monitoring, and found their way into all manner of hospital equipment. This isn't meant to downplay the changes brought forth by the microcomputer, which with the advent of the Internet are enormous, but merely to place the minicomputer in the light of day. The changes were different from the micro, but certainly not unimportant. ______________________________________________________________________ | | | | Carl Richard Friend (UNIX Sysadmin) | West Boylston | | Minicomputer Collector / Enthusiast | Massachusetts, USA | | mailto:carl.friend@stoneweb.com | | | http://www.ultranet.com/~engelbrt/carl/museum/ | ICBM: N42:21 W71:46 | |________________________________________________|_____________________|

You might take it apart and reseat the keyboard connector or ribbon whichever it may be. As for power supplies, you should be able to get an equivalent power supply at radio shack. Just bring the atari one in, and they should be able to match it. I can ship off a couple of disks to you with DOS, and a few games. I will check out your web page for your address, but if it's not there, just let me know where to send the disks. There is a guy here in Austin, that has a lot of atari software for sale at really great prices. His name is Rick Detlefsen and his email address is 74766.1561(a)CompuServe.COM I have bought some software and an 850 interface from him, and his prices are great. I think I paid $0.60 for a Robotron cart from him, and it even had the box and manual. I will put together a few disks with some stuff on it, and send them to you. Hope this helps.
