HP IIISi "55 SERVICE"?

by mouse＠Rodents-Montreal.ORG

I have an HP IIISi printer. It was working fine. Then it sat idle for quite a while (some small number of years, I think); then it was moved (the movers picked it, and a bunch of other stuff, up and held it for a few months before bringing it to the new place). Now, the printer doesn't work. I turn it on and the front panel does a brief lamp-test (each lamp in turn turns on briefly), the display says "05 SELF TEST", then "SWITCHING TO PS", then "55 SERVICE" with the 55 flashing. I did a little noodling around and found hints that this indicates some kind of internal communication failure - and, indeed, I don't hear the brief motor-and-solenoid noises that (admittedly hazy) memory says normally accompany selftest; after the clunk of the power switch as I turn it on, the next sound is the clunk of the power switch as I turn it off in exasperation at seeing "55 SERVICE" again. (It's possible there are fan noises, but there are enough fans in the room that it would be had to tell unless they're fairly noisy fans.) I found a PDF on www.lbrty.com which purports to be a IIISi/4Si manual, probably a service manual from the context and the "sm" in the filename. But every page just gives me "**** ERROR: Unable to process JPXDecode data. Page will be missing data." and an empty page. I am looking into other possible ways to get its content, but, in the meantime, does anyone have anything to suggest? I'm not afraid of voltmeters and soldering irons, but my test equipment is limited - I don't, for example, have a 'scope or logic analyzer I can use here. I do have a pretty good multimeter - a Fluke 87 - though. I took the printer apart to some degree. I've had it apart before; there was a power filtering cap that went and arced enough to eat away some of the PC board under it. I cleaned it up and replaced it and it's worked fine ever since...until now.

Original Mac numeric keypad & Mac Plus keyboard for sale

by lproven＠gmail.com

The gradual garage clearance continues. Mac Plus keyboard (with integral numeric keypad, no cable) http://www.ebay.co.uk/itm/271305613659 Original Macintosh numeric keypad http://www.ebay.co.uk/itm/271305622663 No packaging or anything, I'm afraid. They could do with a good clean, as well. Posted because Jules just recently mentioned that he was looking for one. I've put them up with a starting bid of a tenner. I hope that does not seem too much like price-gouging, but I was not willing to go for my usual 1p approach with some genuine rare (not "ebay rare") kit. Apologies for the spam! -- Liam Proven ?

Asteriods arcade cabinet

by tpresence＠hotmail.com

Maybe this isn't the perfect match in context for the list, but I'm guessing its as good as any. I've had a classic asteroids arcade cabinet since I was about 16 (1985). We ran it off and on for a few decades, and then it sat in the garage for a while. Last time I turned it on, the vector screen initially displayed only a center dot, then a line, then the full screen after a while of being on. I wan't to bring it back up again. What precautions or efforts should I take to get the machine back up? I don't want to damage it. The only repair made so far was a replacement of the lit player 2 button. Kevin

Anyone have any info on a Bendix 3001 terminal?

by ethan.dicks＠gmail.com

Hi, folks, I did some preliminary googling and didn't find any obvious hits for this terminal. It has a metal shell, blue textured paint, a couple of switches on the back for features, a DB25, and the older type of modular power plug often seen on instruments - the short recessed oval with 3 pins. I plan to dust it off, check for loose things, then examine the PSU before even thinking of powering it on. If I had to guess, and I do, I'd expect it to be a glass TTY no smarter, and probably a lot dumber than an ADM3. Anyone have any facts about it? I'll know more when I get a chance to open it and clean it, but I thought I'd ask. Thanks! -ethan

S-100 80286 CPU board write-up

by monahan＠vitasoft.org

Good news, It now looks like our new 80286 Master/Slave S100 bus CPU board works fine with not only our 4MG Static RAM board bit also the 1M RAM/ROM board. The problem I outlined below was due to the fact that I had jumpers wrong on both the CPU and ROM/RAM boards. The 80286 works fine with both boards at 11MHz (with no wait states). One of the reasons for "upgrading" the ROM/RAM board was to simplify the "rats nest" of jumpers on the earlier boards for the diverse range of RAM & RAM chips (including flash RAM) that board can use. The new RAM/ROM boards should be here soon. If you have the older board, consider switching over (it uses all the same chips/parts) . For new users it is a very useful memory board. One remaining bug I see with the 80286 board is that some older S100 Static RAM boards (particularly those that use PALs, such as the Godbout 128K static "RAM21" board or the BG Computers 256K Static RAM board), need a patch. You need to bend out pin 2 of U56 and jumper it to pin 9 of U68 - the bus controller. This seems to provide the early MWRITE status signal these boards require. Interestingly this is also the case for our 8088 CPU board (jumper K5,2-3), but not the 8086 board. I have written up a detailed account for the 80286 boards construction here:- http://www.s100computers.com/My%20System%20Pages/80286%20Board/80286%20CPU%2 0Board.htm And a description of the RAM/ROM board here. http://www.s100computers.com/My%20System%20Pages/RAM <http://www.s100computers.com/My%20System%20Pages/RAM&ROM%20Board/RAM&PROM%2 0Board.htm> &ROM%20Board/RAM&PROM%20Board.htm Enjoy John From: John Monahan [mailto:monahan at vitasoft.org] Sent: Sunday, October 20, 2013 10:53 AM To: 'n8vem-s100 at googlegroups.com' Cc: 'cctalk at classiccmp.org'; Andrew Lynch (andrew-lynch at sbcglobal.net) Subject: S-100 80286 CPU board write-up Hi everybody. I have just written up construction notes on this 80286 CPU board. Please see here:- for details:- http://www.s100computers.com/My%20System%20Pages/80286%20Board/80286%20CPU%2 0Board.htm Unfortunately there are some strange issues with the board running with RAM boards other than our 4MG Static RAM board (described here:-) http://www.s100computers.com/My%20System%20Pages/RAM%20Board/4MG%20RAM%20Boa rd.htm With that RAM board, the 80286 is rock solid at 11MHz (no I/O or ROM wait states required). Please see the bottom of the page for details. I am traveling all of next week but will explore further when I get back. Sorry about the bad news John

HP 95 (?) Serial Cable - Free for Cost of Shipping

by robert.jarratt＠ntlworld.com

I have a cable which I *believe* is for a HP 95. It has a DE-9 female connector on one end and some proprietary looking connector on the other side, which seems to have 4 pins and is also female. If anyone wants a photo I can arrange to take one and send it to you. If anyone wants it they can have it for free as long as they pay the cost of shipping. I am in Manchester (UK). Regards Rob
