The good news : I've got the HP Datacomm program, and it seems to work fine with that HP82915 modem board that I mentioned last week. Amazingly, then, the kermit supplied by HP for the Integral does not support the modem. Hmmm... One to watch for if you're trying to get one of these modems to behave. Alsa, from what I can see the Datacomm program is user friendly (in other words, hacker hostile). It only lets me set 300 or 1200 baud (why not 110? A 300 baud modem will work at lower baud rates). It only uses the modem in 'originate' mode. It does pulse dialling, not DTMF (why???) But it seems to work. My only problem now is getting something for it to talk to. I have no intention of using it on anything other than a bit of cable on my bench, so approval is not a problem. Maybe I'll just dig out an AM7910 chip and start soldering... -tony

HP DIO GPIO card 'options'

by ard＠p850ug1.demon.co.uk

I've just boaght what appears to be a brand new HP 98622 GPIO card. This is the 16 bit parallel I/O card for the DIO bus, as is used on the 9836, etc It came with a user manual. This was a lot more use than I expected it to be as it includes a schematic. It's a fairly thin manual, but full of information. One interesting diagram at the back shows the correspondence betweene the DIP switches on this card and the links in the 98032 I/O module for the 9825... Anyway, it describes 4 'options' for this card. Each one was a particular cable -- one was the 50 pin Blue Ribbon plug to fit the card and bare wires on the other end. The other 3 were wired to connectors to fit the 9885 disk drive (9" floppy), a Multiprogrammer (I forget the number, but the one that didn't have an HPIB interface) and finally one for the 9866 printer. The manual does give the switch settings to use the board with each of these devices, but no wirelists of the cables. And amazigly I have all 3 of the listed peripherals. So my question is obvious. Does anyone have any of these cables and could 'buzz out' the wiring? -tony

Looking for info/software/anything for 9-track adapter

by tubastuff＠inbox.com

Howdy list, I've just picked up a Computer Logics PCTD III 9-track tape drive ISA adapter board. It has a 68-pin D-sub socket on the mounting bracket for connection to a Pertec interface drive (I've got a brand new Fujitsu M2444AC). My problem is that I have no documentation or software at all for this thing. I called Chi Corporation to see what they have for it and they said that they've long since disposed of any information on the card. The only thing that the guy at Chi could remember is that it doesn't work with faster CPUs. So I'm stuck for any information on this board. I'm looking for either copy of software or technical documentation for the card. My intent is to write either a Linux or XP driver for this thing and I'll be happy to share the results of my work. Can anyone help out? Thanks much! Chuck Guzis Sydex, Inc.

TSX Plus...

by lbickley＠bickleywest.com

Several folks have sent me Emails concerning the status of getting TSX Plus online. The delay is my fault: I changed ISPs recently and have had to move our company website, ftp, mail, etc. to the new site. We are also in the process of becoming the U.S. mirror for a large european SGI tech. info site (hopefully to be completed in a week or so). I'll post it when it's up and running. I expect to have the time within the next couple of weeks to have all the TSX-Plus goodies available online. Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.

Look under "disk/software images" near the end of the main page. The disks can be created with my ImageDisk program which is available on the same page. NOTE that I just fixed the link to KAYPRO4.ZIP which was apparently broken - it should work now. Dave PS: If you would like to return the favor, please send me ImageDisk images of the Kaypro 4 (83) and Kaypro 10 boot disks as I do not have them yet. -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Collector of vintage computing equipment: http://www.parse.com/~ddunfield/museum/index.html

New updates to the Little Orphan Tomy Tutor site

by spectre＠floodgap.com

New updates have been made to the Little Orphan Tomy Tutor site. The Tomy Tutor is an American home computer released ca. 1983 with strong hardware commonalities to the TI 99/4A. The Little Orphan focuses on the American Tomy Tutor, along with its Japanese cousins (the Pyuuta series), and offers a catalogue of hardware and software, programming information, technical documentation and links to related sites. Here's what's new or changed: - Pyuuta Jr. entry, featuring a complete description of this Japanese console version -- yes, I finally got one! Includes pictures, scans from the manual, and screen grabs of its surprisingly robust and user-friendly interface (for 1983, that is). - Stub entry for the Grandstand Tutors, the vanishingly rare UK variant. - New emulation section. This includes a special section on using the MESS Tomy Tutor driver (focused more towards the Mac, since I'm a Mac user, but with help for Windows users as well) and needed firmware and dumps, intended only for those with a legal right to the hardware, of course. Also includes TutorEm, the first true emulator (Windows-only), and incorporates Tutti as a museum piece (though people who do not own a Tomy Tutor can still use it to legally simulate the Tutor without ROMs). Alas, with this site release, I have chosen to officially freeze Tutti, the first Tomy Tutor simulator of any kind, at 0.3. It will still be left for download indefinitely because of its unique legal status, however. - Updated Incomplete Catalogue. Improved screenshots for many games, new shots for many more (including the believed-unreleased Gajigoji and Jack In The Box), and additional stub entries for hardware to come later. All of the American clone games have also been matched up to the Japanese originals. Also included links for the MSX and CoCo ports! - Additional Pyuuta screen shots. - Updated my personal trade list and the General and Pyuuta pages' histories, and made various custodial changes. Have fun! http://www.floodgap.com/retrobits/tomy/ / READY -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.

Computer Machinery Corporation?

by tomj＠wps.com

Up at Apex today, this is what I saw, part 1: http://wps.com/temp/CMC1.jpg http://wps.com/temp/CMC2.jpg http://wps.com/temp/CMC3.jpg It's a 12-bit machine, but big odd non-DEC-looking boards. It's 7400 TTL, with 1974 and 1973 dated-coded chips. Both machines are ruined. Sacked in mud, probably for a decade. Little rust though, looks like damp, then blown-in dust or silt. Boards are possibly recoverable. No memory or any accessories within 10 feet, I think they were buried under junk and just unearthed (Don is going through the yard). The switch register is 12 bits, and a LINK light, so I assume it's a pdp8 clone. Could be wrong of course.

ISO Datapoint 2200 service manuals

by aek＠bitsavers.org

As long as the subject of Datapoint has come up, I'd like to ask that people keep an eye out for 2200 and related service manuals. Several people are trying to restore them right now, and locating the service docs has been difficult. I would assume they're of the same detail as the one I have for the 3300 terminal.

(And a good photo of the Datapoint 2200) >http://www.swtpc.com/mholley/History/SWTPC_History.htm > >Michael Holley >From a pure economic point of view the front pannel was a very expensive addition and for the micro world it easily doubled (or more) the hardware for a base system. Additionally the hardware was both bulky (switches) and even in volume costly. SWTP by going with a rom monitor made a simpler machine with fewer parts. The cost to produce was lower and they also gained in that when roms, and other digital parts became cheaper they could pass the saving or reap the profit where switches and leds didn't drop in cost nearly as fast. There were a bunch of subtle evolutionary ideas in the SWTP systems that were widely adopted such as standard IO types and addresses. The effect being the user was less likely to have to configure the hardware and more likely to find new software [especially for similar but not identical systems] that were compatable. All of this was an outgrowth of how Motorola supported the 6800 vs Intel vision. The offset was with a front pannel troubleshooting a sick system was often easier but was an expensive artifact when not needed. Even though 6800 and 6502 based systems where not my forte' I studied them early on to see why they were so pervasive and largely successful. I feel that their break with the front pannel concept was a jump ahead for them. As a result the next system (ca1977) I'd gone with was a NS* horizon to get away from the switches followed closely with Netronics Explorer8085 for the resident rom monitor for S100 diagnostic abilities.
