Need 4-pin PSU to front motherboard connector for Sun V210

by microcode＠zoho.com

A kind-hearted list member sent me a PSU and some RAM for my V210. I finally got around to installing stuff today and I found out one of the connectors on the new PSU I received has shattered and splintered and can't be used. Apparently from heat or age or both it became so brittle it started disintegrating and the pins must have gotten damaged along the way. The connector I am talking about is the 4 pin square connector that goes through the bulkhead to the front system board and terminates behind the system configuration card. The PSU I was going to replace failed today after I put it back in when the new one couldn't be used. Although the BIOS is showing every possible PSU error the system seems to run ok, as before. Sun sure made good stuff! Their servers even run fine with a failed PSU... As I was doing all this I spilled a nice full cup of coffee (that I had deliberately moved out of the way, or so I thought) all over a Filco while moving stuff around so I could work on this machine. At least now I get to test the "wash the keyboard in the shower" theory. So far it's dead but maybe it will start working again when it dries out. If not that was an expensive cup of coffee. At least the RAM I installed works. Anyway, is it possible to get a hold of these connectors along with the crimp-on pins? They look fairly standard, I just don't know who sells stuff like that. I don't know if I can post attachments to the list but I have pics if anybody can help. I'm also looking to buy additional PSUs and RAM for V440 and V210s. Somebody had said they had some RAM to give me but it's been a long time and nothing heard. If you have anything to sell please email me with your prices. Thank you.

Also a Quantum 2020 was Re: M7555 For How Much???

> Anyone seen: > > http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190684935842 Surplus dealer in Cleveland with unrealistic expectations. Since he deals in medical and process control equipment he probably sells enough big stuff so he doesn't have to worry about the small stuff. At least he takes offers so he is negotiable. Most of the listings are a set (buy it now) price or best offer postings. And it is a new Ebay requirement that you offer a minimum of 14 days if you take returns. This is reflected in their recent postings. Of probably more interest to the list is this offering, a Quantum 2020 8" hard drive from him. I would recommend making an offer rather thatn taking the buy it now, but he is offering free shipping and the Quantums are heavy. http://www.ebay.com/itm/Quantum-Q2020-20MB-Disk-Drive-SA1000-Interface-/251… I didn't check their feedback on packing and would recommend doing this if you are interested.

So much that even the minimalistic switch front panel is handled in the CPU microcode. I've learned that when I repaired our 11/10. Oh, yeah! NOW I remember what an 11/05 is, the really short (3U?) machine with the single-line front panel. YES, for some reason I was thinking of the 11/20 or whatever the first model was. You are certainly right about it being microcoded including the front panel control. I did work on an 11/05 about 1980 or so. We moved up to a used 11/45 and then got a VAX 780. Jon

PDP-11/05 Control (M7261) won't deposit

by ian_primus＠yahoo.com

Working on a PDP-11/05. The front panel appears to work, I can step through and examine addresses in memory, and I can run the CPU and halt it. Deposit, however, does NOT work. When the deposit switch is flipped, the LED's show the correct value, but examining the address again shows no change to memory. I know that this board is the problem, having swapped in a module from a working computer. I can, with the good board, toggle a test program into core. Then, shut it off, switch in the bad board, and the program (still in core) runs, and I can examine all areas of memory and see it correctly. I've only begun to glance at the schematics for the control board, but I would assume there is some kind of write buffer that's not working correctly. I'm going to continue to try to figure this out, but without a card extender, it's very difficult to troubleshoot. Anyone have any ideas on where to start? Failing that, does anyone have an extra M7261 available? :) -Ian

Does the address increment when you hit deposit? If so, that means the switch is being sensed. So, the problem is likely the write command is not getting to the memory. There are a bunch of ways to make a front panel work, but since this is a raw logic machine (no microcode) they probably worked hard to minimize the logic needed. So, probably the deposit and exam logic share a lot of functions, but there is probably a FF that is set for deposit and cleared for exam, and then feeds through some gates to perform the memory read or write. Something in that chain of logic is most likely where the problem is. Jon

UC08/III to UC08

by shadoooo＠gmail.com

Hello. I have an UC08/III, the quad QBUS board with two SCSI controllers, with metal panel for MicroVAX). I would try to convert it to a plain UC08, the version for LSI11 without the metal panel. The doubt is about the electrical compatibility: if I could remove the panel and solder in place the 50pin berg connectors, the card could work on a PDP11 in MSCP / TMSCP? Andrea

Sounds like there is nothing wrong with your controller. I would suspect the software have problems with such large disks... Not that uncommon actually. It wasn't until RSX-11M-PLUS V4.6 that RSX correctly handles disks larger than the max capacity of the OS (which is 8GB for RSX, by the way, but most other OSes have smaller maxes). Johnny

pdp-8/m for sale in Northern Virginia

As much as I would love a pdp-8/m, and as much as I'll probably kick myself for not calling about this, the expense of buying it, crating it, and having it shipped it to California would just more than I care to take on right now. If this were west of the Rocky Mountains, it would already be in my car :) I have no more info than what's in the post.

FS: RA-81 drive spindle and disk enclosure

by alanp＠snowmoose.com

I am cleaning out the garage. Found a couple more RA-81 pieces to pass on. These items are light enough that there is no problem shipping them. Items are located in the Seattle area. The drive spindle is about 7" diameter and 6" tall. The platters were stacked on vertical separators with the spindle in the center. There is a pleated air filter that goes around the inside, center of the spindle. The disk enclosure is about 16" wide, 18" long and 7" tall. It held the platters, spindle and head assembly. As far as price, make an offer. I really just want to get stuff out of my garage, but, if someone wants to pay for the stuff that I am getting rid of, that would be awesome.

Human language [was RE: Line length [Re: VT220 focus]]

by RichA＠vulcan.com

From: Rod Smallwood Sent: Wednesday, May 23, 2012 9:09 PM > Japanese code for example was totally different as their language is > based on ideographs. Please stop spreading erroneous information. One of the writing systems used for the Japanese language, kanji, is _logographic_ (each written sign denotes a word). In reading Japanese, each such sign can be read in as many as 10 different ways, depending on whether it is read as a native Japanese word (or morpheme, that is, a unit of word formation possibly "smaller" than a full word--English "-ly" is an example), called kun-yomi "Japanese reading" or as a Chinese word in one of 4 different sets of pronunciations (kan-on "Han sound", the most common; go-on "Wu sound", used chiefly in reading Buddhist texts; to-on "Tang sound", used in reading some later literature; and kany?-on "idiomatic sound", which are often "correct" Chinese pronunciations which violate the rules for the other 3 systems). The occurrence of synonyms complicates things further. In addition, there are 2 additional scripts, both ultimately derived >from simplified ways of writing kanji, called hiragana and katakana. Both are syllabaries, that is, each sign represents a single syllable of the word, and multiple signs are used to write the word. The Japanese *language* is based on vocalizations produced by the human throat and mouth, representing neural events in the brain, like all other human languages.
