Used to use one quite a bit; when I started working here, that was the CP/M machine of choice and we had a couple of them (the non-CP/M machine of choice were the Micro PDP-11s that DEC kept throwing at us). Someone had built a custom interface between one of them and a PC05 to punch paper tape to ship out to folks who did our wire-wrapping (the software to generate the paper tapes was either in FORTRAN on the PDP-11s or PL/I-80 on the Digilogs; shortly after I arrived we moved the FORTRAN version to the VAX-11/780 we had just installed (sigh; I was the only user of the 11/780 most of the time and I had a whole gigabyte of RM05s to play with; those were the days), so I never had to use the PL/I-80 version of the wirewrap software). We started picking up Televideo 802s and 803s about that time and migrated from the Digilog to them. No promises, but I _may_ have a CP/M boot disk for the thing and (depending on how recently my cow-orkers have cleaned their offices) I may be able to find a bit of technical info.

You usually can't tell what system it's for even _with_ being able to read it. Roger Ivie ivie(a)cc.usu.edu

Atari XDM121 printer help

by jeffh＠unix.aardvarkol.com

I just recieved an Atari XDM121 printer, and it appears to work fine, though is in need of a new ribbon. It is a daisy wheel printer, 80 column, and is set up to connect to the Atari 8bit I/O bus. It appears to have been produced in the mid to late 80's since the style of the case and buttons on the front are the same as those of the Atari ST line of computers, and not the earlier 8bit machines (ie. the case is grey and the 3 buttons on the front panel have diagonal vertical lines). My question is about a third connector on the back (the other two being the 8bit I/O bus connectors). This third connector is a modular connector, similar to a RJ-11 phone jack, and it has just two contacts in it. Any ideas on what this might be for? Any help would be greatly appreciated. Thanks.

Good Emulators & floppies (was: C64 CP/M carts (was:...))

Wheeeee! ;-) >it can read/write/format PC floppies. The atari ST could always (well, production models on, anyway) read/write PC floppies. Formatting, however, was initially a problem. It seems there's an unused field somewhere in the admin stuff on a pc floppy that Atari figured didn't matter. So they left it blank. But, for some reason, IBM machines needed some value in there. (I'm probably way oversimplifying, and making errors...) So floppies formatted on the atari worked fine on the atari, but if you wanted to use the floppy on both machines, you needed to format it on the PC (or use a third party formatter that fixed the problem.) Some later version of TOS (1.4?) fixed this. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

'Orange Wall' FREE!

by kyrrin＠wizards.net

Ok, got another freebie for the group. I have the infamous DEC 'Orange Wall' worth of docs on VMS 4.whatever, at least a couple of big boxes worth. As I don't anticipate running VMS (heck, I don't own a big VAX!) anytime soon, I would rather see these go to someone who needs them. If no one speaks up, I'll recycle the innards and use the binders. First one who wants to visit me in Kent, WA can have 'em! -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.

Salvation Army (was RE: IMSAI 8080 production count)

| In my experience, the "volunteers" at the Salvation Army filtered out | anything that even resembled computers so that they could sell it | themselves. If it comes in a box and has a detach keyboard (i.e. looks | like a PC) it never gets to the showroom floor. Trust me.... I *know* Well, I don't think they're selling them themselves... if they have a policy (perhaps nationally) like the western washington Salvation Army headquarters in downtown Seattle, they auction off pallets of donated computer equipment to the for-profit thrift organizations such as Value Village, Thriftko and Shop & Save. Unfortunately, the Seattle headquarters holds the auctions not monthly, not weekly, but DAILY, and at 8:30 AM !!! Kai

We could have them shipped to one place and re-shipped from there; USPS should be around $3-5 if you're not in a hurry. (And I'm not worried about them becoming obsolete before I get mine...) If they're shipped to the bay area, I've got lots of boxes and packing materials I need to get rid of... (I'd volunteer to handle it, but I'm new to the mailing list, and if it were me, I would trust me yet.) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

VIC stuff, ComputerSpace, and SuperPET update!

Fortunately for me my wife understands, as she has read, it is easier to get along with your spouse if each of you have a money-pit hobby, hers is mainly knitting, spinning, and fabrics, and mine classic computers.

I keep reading about it, but no good descriptions. What were the controls, the layout, the game play, etc. ------------ SuperPET update! Well I was a little bit conservative in my estimation of daughterboards on the SuperPET, the count is now three (well technically four, one of the daughterboards has a daughterboard itself.) I discovered the bottom-most daughterboard seemed to be loose so I had to do a partial diassembly to get to it. It would seem that the bottom-most daughterboard plugs directly into the 6502 socket of the 8032 motherboard, and that daughterboard was not seated in the socket (which is raised with about 4 stacked chip sockets!) Continuing on, I discover that also some of the pins on the bottom of the daughterboard were bent and *sigh* some broke upon attempt to get them back in line (they should be replaceable, but not too easily.) For now, I decided to re-assemble it (and all the various cross-connections and such). Also, I had gotten word back from the person who has a SuperPET and set the switches to work as an expanded 8032. I now can get the 'jingle' sound and a screen full of garbage characters! (Not a complete victory, but a very good amount of progress here!) Plus, the gentleman does have some of the disks: >Yes, I have most of the Waterloo software stuff, for sure the assembly >stuff, the Pascal possibly, the Fortran for sure, and possibly the >BASIC. I may even have the Cobol stuff... I really don't have the time or space to do much more presently, (one of these decades when I retire or win the lottery) but will work on getting a set of the disks, for future use. This is so much fun, my Commodore collection is getting there!

Aim65 (fwd)

by dastar＠crl.com

Here's some info from the guy about the AIM65s. They sound like nice units. Marvin, please e-mail me so we aren't stepping on each other's toes. Sam ------------------------------------------------------------------------------- Computer Historian, Programmer, Musician, Philosopher, Athlete, Writer, Jackass ---------- Forwarded message ---------- Date: Wed, 18 Jun 1997 13:02:40 -0400 (EDT) From: Mikeooo1(a)aol.com To: dastar(a)crl.com Subject: Re: Aim65 Dear Sam, They are all in new working condition.The beauty about the Aim 65 is that it was a single board computer which was self contained in that it had its display,printer,and memory all mounted on its board so that peripheral attachments weren't necessary.Yes,it comes with a keyboard and power supply also.I developed a plastic enclosure and metal base and ROM board for the system so the keyboard and power supply could be housed with the Aim in a compact unit and programs could be burned onto eproms which would seat in the ROM board rather than rely on tape storage which involves a recorder hookup and would be quite slow. Best Regards Mike
