FWIW, the language is very similar to APL/360. The nasty part was the special symbols. The console keyboard (basically a 029 keyboard) was mapped into three shift states (3 symbols per keycap) with the shift state being indicated by banks of front panel lights. IIRC, make sure to make lots of copies of the APLIPL card as my experience was that the reader/punch would occasionally munch it. Also IIRC, the correct name for the IPL card is a "Cold Start" card. > We also have the maintenance manuals and schematics, but > no diagnostic software listings.

To garbage or ask for it: Commodore printer MPS801, TIs, Commodore 1525, DEC LA50, TRS80 Mod II exp box etc...

by claudew＠videotron.ca

Hi Garbage day tommorow and I will be scrapping more stuff I have accumulated too much of... This all going to charity (they probably wont want this) or garbage in about 24 hours or pick it up if you want it. I dont wanna start packing -- you have to have someone to pick this up. I know this is quite a long shot since I am in Montreal, Canada but who knows... A shame because most was cleaned and is working....most of this is stuff I have more than one of or just no space for... I anticipate more stuff getting junked so anybody with a large car or van that can pass by here can probably fill it up. MPS801 Commodore printer Commodore 1525 printer DEC LA50 printer TRS80 model II "8" floppy expansion box" with no drives Compaq portable II TI994a beige version TI994a black version Several MAC Plus and SE (no se-30s) Apple IIc Several C64 and Apple books some in french Some C64s and 1541 drives Untested 1084S monitor Stuff I cant see myself throwing in garbage but would like to see go to a good home : several Atari STs and Amiga 500s...

I remember an early brochure for the 11/750 talking about how it would be easy to load custom microcode to emulator other processors.

I don't think the DSSI drives have a PDP-11, but they are pseudo-CI. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

HP 64000 cross-development system. Some used DC100 tapes as distribution media, others used 5.25" floppies. -Frank McConnell

I only wish the thing was documented so > I could get from Apple OS 7.x and/or A/UX to something like NetBSD on > it. Apple's refusal to document the system was one problem. Another problem I had (that I started griping about during the A/UX 3.0 beta test) was Apple wouldn't let the engineers support the GPi pin on the serial ports under A/UX because not all Macs had the GPi pin. I continuously pointed out that all Macs that could run A/UX *DID* have the GPi pin, and they could allow this to be a configuration option. Without the GPi pin there was no way to have secure dial-in and hardware flow control, which means you really didn't want to have a dial-in connection on your A/UX system. There's a lot of other ways Apple mistreated IIfx owners. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

DEC DESPO-A Transceiver?

by lipo.ml＠gmx.at

Hi, does anybody know something about the DEC DESPO-A BNC Ethernet Transceiver? Its a small box (about 115*60*35 mm) with a BNC connector and a MMJ connector on the otherside. And ther is a cable wich on one side has the MMJ and on the other side a big black connector (don't know the name) which I have seen at token ring MUAs only. I haven't seen those token ring connectors for ethernet, and no BNC connectors on token rings. So I am a little bit confused about the purpose of these boxes. Looks like a ethernet/tokenring bridge but I don't believe this. Regards, Lipo -- Roland E. Lipovits Vienna, Austria

Final numbers on Apple IIgs computers for sale

by r_beaudry＠hotmail.com

Hello all, First let me say that I hope all of you are all right, and that your lives are as normal as possible given the recent events. I know it's hard to think about old computers at a time like this, but I did at least want to let you all know what was happening. Obviously, if there are any delays in our transactions, I certainly understand ... Take care of what's important first.... Bear in mind that these systems are school surplus. They WILL need cleaning, and many have stickers, sticker residue, magic marker writing, etc. They are all in good physical condition (no rust, no cracks in the cases, etc.), but they all need to be cleaned. Here are the final counts on the IIgs stuff... These are all tested and working: - Qty. 14 ROM 3 IIgs CPUs, with power cord, NO internal cards. - Qty. 8 ROM 01 IIgs CPUs, with power cord, and memory expansion card (only one bank full on each). - Qty. 22 5.25" Floppy Drives, Model # A9M0107, with cable - Qty. 23 3.5" Floppy Drives, Model # A9M0106, with cable - Qty. 12 AppleColor RGB Monitors, Model A2M6014, with power cable AND signal cable (see below ... more available) - Qty. 9 mice, with ADB connector, labelled as Model # A9M0331 - Qty. 7 mice, labelled "Apple Desktop Bus", "Family # G5431" - Qty. 3 Apple Desktop Bus keyboards with cable (see more below) - Qty. 2 Macintosh LC II CPUs, with power cable - Qty. 2 Macintosh Color RGB Monitors, with power AND signal cables - Qty. 2 Apple IIc computers, with power supplies The following are untested: - Qty. 5 Imagewriter II printers, with power AND data cables - Qty. 17 Apple Desktop Bus keyboards and cables I am willing to test the remaining keyboards, and the Imagewriters if people want them. I also can get more monitors, but again, I only want to lug them here and test them if people want them. Please, even if you have responded before, respond with a specific list of what you want. Don't tell me "a complete system", because I have no idea what that means (mouse? 1 floppy? 2 floppies? ROM version? Monitor?). BE SPECIFIC. The two types of mice listed work with the IIgs, but I don't know if either is "correct" in that I don't know which version shipped with the IIgs. Because some items are limited in supply, if I get more offers than items, I will throw names into a hat to decide who gets what. PLEASE INCLUDE A ZIP CODE OR COUNTRY WITH YOUR RESPONSE so I can determine shipping costs... Once you respond with a want list, I will determine if I can fulfill it, then weigh everything, and get a shipping quote. In terms of money and shipment ... Payment must be in US funds, and I accept PayPal, or Money Order (International Money Order for overseas). The cost of each order is a minimum of $5.00 + "shipping". What this means is that a single cable will cost at least $5.00. A complete system will cost at least $5.00. Anything over $5.00 is up to you, bearing in mind that ALL proceeds will be donated back to the school I got the computers from. There is no special priority given to people who donate more money. "Shipping" includes actual postage (USPS from Westminster, MA USA 01473), plus actual cost of boxes and packaging (no more than $5.00, even for a complete system). Monitors and printers will be shipped in SEPARATE boxes from CPUs. If you come to my house to pick them up, you can "cherry-pick" for the best cosmetic condition. Thanks! Rich B.

IBM 1130

by brian＠quarterbyte.com

Good to hear there some other 1130 fans out there! I should have added that we have ten disk cartridges with our 1130. One is labeled "IBM Only" and we hope it's a CE disk. We didn't find any punched card based software other than four IPL (boot) cards. One is labeled "APLIPL" and we have an APL typeball, so we think one of the cartridges has APL on it. However, we're a long way from trying to spin it up to see if the disks are still readable after what must be 20 years. We also have the maintenance manuals and schematics, but no diagnostic software listings. We'd be interested in getting copies of anything you get scanned or OCR'd, Hans. Norm is setting up a boffo website for it all. A grand opening announcement will be coming soon! And as for Jonathan's observation: > Oh my, an 1130! I don't think we've ever encountered such a severe case of > the classic computers disease. Brian, you need help. I don't think we can claim to have the worst case around here, no sirreee. On the other hand, Norm was suggesting that we port the 1130 emulator to the Palm platform and ...
