by spedraja＠ono.com

Hello. I've recently acquired one AT&T / Olivetti in perfect shape. It has installed the 3.5 version of the AT&T Unix and is fault of the Development Set for this release. Someone has this and other software available for this machine in 5'25 format, please ? Let me know. Thanks in advance Sergio

Fiche scanning (was Re: [Simh] Listings of XXDP test and maindec's for 11/70)

by vern4wright＠yahoo.com

Ethan, I have some small experience in fiche scanning. Several years ago I was researching/writing a biographical essay on an interesting scholar and adventurer in my family. His published writings were in the 19th and early 20th century, and mostly available only on microfiche. I'd suggest checking with your local university. I lucked out at a local university (SDSU, in San Diego). I found a fiche printer with a add-on which wrote the image off to disk. It wasn't automatic but as I recall it was about 2min/page for scan to writing the disk. The images were very good; had the typefaces not been antique, I could have applied OCR in my own office. I suspect that the technology will be vastly improved and available for use. Good luck.

If your printer doesn't come up on their memory selector, give their 800 number a call. I have found them to be unfailingly polite and helpful in assisting me when I want to know what memory will work with something obscure. Some times the answer is, "We don't know." But they've admitted that in a competent way, as opposed to trying to sleaze their way through. And if I can supply some technical details they'll sometimes make an educated guess with caveats. That's how I found the memory module for the Kyocera C170N. There's some info on Kyocera's spec sheet about the type of module used. The Kingston guy didn't have any info on that printer yet, but thought that one or both of two of their modules would likely work. At that point, I had the choice of buying one directly from Kingston with a nice return option if it didn't work, or gambling and buying it from a discounter at a lower price with a less friendly return policy.

pdp-8/e fault

by rodsmallwood＠btconnect.com

Hi My pdp-8/e has developed a nasty fault. I have all the manuals and a scope but before delving in too deep I thought I'd see what the 'Hive mind' knew. Its straight forward enough of a fault. I can no longer toggle in values via the switch register. The address sets up ok and the switch register value appears to transfer to core on raising DEP. The location counter increments normally. However going back and checking the locations shows nothing there. It does not appear to be a problem with the core as replacing the low address 4k with a higher one makes no difference. Experienced PDP-8 fixers please comment. Rod Smallwood

KM11s and the PDP-11/20 (was Re: Help w/DEC H742 +15V...)

No. I wish I did, but I got a pair of KM-11s since I have several DEC devices which can use them (RX01, RK11-C, RK11-D, PDP-11/05, PDP-11/20). I don't happen to have an 11/40. The primary purpose for my KM11s, was to facilitate the restoration of my 11/20 - it was butchered and dumped prior to me acquiring it (I rescued it from the skip at work, already in many pieces), and to attempt to get my RK11-C working (it arrived from the same place intact, but is suffering from some visible corrosion on the pins of the backplane, so I don't know if I'll ever get it working reliably). I don't need to do much RX01 electronic repair (a new drive motor and a new stepper motor would go a long way to returning both sides of a dual drive to work, but the boards seem intact); however, I think it'd be cool to watch the drive work by observing the blinkenlights. These items are way, way down on my DEC list (I have PDP-8s to work on first), but someday the 11/20 will bubble up to the surface. I know I don't have all the core that originally came with it - one of my cow-orkers souvenired it 20 years ago. I have the backplanes and the driver boards, but am missing at least one 4K core plane. My _hope_ for this system is to get an older version of RT-11 up on it first, then *perhaps* if I can get enough memory on it and some compatible disk device, see if there's an ancient-enough version of UNIX in the PUPS archive to run on it (it would have to be a version from 1971 or 1972, IIRC, to fit on a KA-11 w/16-bit address bus). I don't know that it's possible, but it's a goal. I'm thinking that the RK11-C might work there, or since I know it works, the RK11-D, plus one or two RK05s. It's possible that those are too new for PDP-11 UNIX, but for old RT-11, I can probably get away with the SJ monitor and an RX11 w/dual RX01s. First, though, I have a lot of reconstruction to do on the 11/20. IIRC, I will need some PSUs to get the ball rolling, since that's what I think was yanked from it before it was trashed. I think I have the CPU box plus two memory boxes (the size of 3 BA-11s, essentially), but I don't recall the PSU model number off the top of my head - it's one that supports multiple single-height power cards in a series of DD-11C-sized 4-slot hex-height backplanes. Oh... I probably don't have enough M920s to reconnect everything - I don't think many of them were in the dumpster with the CPU. *Sigh* The missing parts is why I never did much with it. Maybe I'm better off trying to recycle the front panel and drive it from something modern. The chances of finding multiple PSUs and short Unibus interconnects that aren't already in an 11/20 seem small these days. -ethan

PDP-8/M progress and problems

by toby＠coreware.co.uk

I've now finished the rebuild of the PSU for my PDP-8/M and have reassembled the chassis and put in a minimal card set consisting of the KK8-E CPU and a 8KW core set. The machine is now semi-operational but I have the following issues left to resolve: 1. Sometimes (generally the first time) when I power the machine on, the RUN light is on and the console is unresponsive to any stimulus (inc halt), although I can cycle the rotary switch to see the various registers/states. Generally if I power cycle, it is fine. Does this indicate power supply instability? I'm guessing the second time I power on, the capacitors are still charged up from the previous powering. 2. Switch 4 doesn't appear to be working (can't set bit 4 for the accumulator or deposits). I've confirmed the switch itself is ok, so think I have a logic problem. Does anyone have schematics for the KC8ML? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

I [don't] hate E-Bay (was Cromemco 68000 on ebay)

by chrism3667＠yahoo.com

you know in all fairness, there are only so many promises even ePay can keep. If someone is unaware, or rather just unprepared to deal w/some risk, uh well, too bad ya big baby. And moreover if you're inclined to believe their line of bull, you're worse off then that. ?In truth though, I've had B-E-T-T-E-R transactions from dealings off of eBay. You do the analysis. It's true. I'm sorry but it's true. Too often (and this is going back years and years, not just recently) someone will put some piece of crap on eBay, and watch the bidding go up, up, and away. The temptation is too much the next time they chance upon some piece of crap left out in the trash. And there's this layer of insulation where you don't have to face the buyer. You can assuage your conscience by saying the bidder just didn't ask enough questions. --- On Sun, 3/29/09, der Mouse <mouse at Rodents-Montreal.ORG> wrote: From: der Mouse <mouse at Rodents-Montreal.ORG> Subject: Re: I [don't] hate E-Bay (was Cromemco 68000 on ebay) To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Date: Sunday, March 29, 2009, 3:55 PM > First, re: "I hate [ebay] because it defrauded me in 2005", that is, > in all probability, BS.?

But if ebay makes promises which it doesn't keep - such as promising to protect each party against the other - then that too is fraudulent. (Whether ebay does make such promises I don't know, but I've certainly seen enough stories to make me think it doesn't deliver if so.) /~\ The ASCII??? ??? ??? ??? ? Mouse \ / Ribbon Campaign X?

Xerox 820-II Questions

by snhirsch＠gmail.com

I just won an 820-II on eBay, but the seller lost the external drive box (hard disk + 8" floppy). Judging by the schematic, it should be very straightforward to interface one of my floppy drives to it (I have a bunch of Shugart, Seimens and Tandon units). The hard drive I'm less sure about. Looks like a proprietary interface of some sort. Can anyone tell me more about it? Does anyone have a spare 820-II drive enclosure they'd like to part with? Lastly, will Imagedisk support creation of a system disk on an 8" drive attached to a Compaticard IV? Steve --
