I just do not do the long drive well any more I remember I would drive straight from AZ to San Jose non stop.... Now I think I would have to break it into a 4 day trip to be comfortable. When it comes to large trucks I just do not do them any more. The cost of shipping has gotten so high ( or maybe it is just the money is just worth less now) Ed# (wishing he was 40 years younger sometimes!) _www.smecc.org_ (http://www.smecc.org) In a message dated 9/6/2016 8:59:10 P.M.

Apple IIGS on epay - local pickup in Seattle

by echristopherson＠gmail.com

Anyone want this? Less than 4 his remaining. Actually I'd love to have someone win it for me and sell it to me at VCFMW, but I've never arranged such a thing so I don't know what to estimate the cost to me would be. (Plus it probably won't stay at $49 for long.) I'd bid on it myself and then worry about getting it to me, but they explicitly day they don't accept third-party shippers.

The huge lot that had the NIB 8" floppies is now on ebay

This, however, I can definitely see as a good move. I will add such a tag to any eBay notification posts I make, and I encourage everyone else who posts such to do the same. > From: Peter Coghlan >> It's a tiny bit more work to use them > Any given posting to a mailing list is sent by one person and read by > many.

And the "eBay:" tag idea follow this principle too, I will note... So let's remember to add that tag, everyone! Noel

Yes it needs to be saved... and yet with all the extra and duplicate stuff CHM has I bet they do not have one of these yet shun it... curious. kick their shins for me Al ok? Unfortunately not close for me to pickup. all this stuff is all part of the history.... Ed# In a message dated 9/6/2016 6:11:35 P.M.

There is also a Unicomp 18 bit minicomputer, paper tape reader, and FFT processor circa 1972 in the garage (6ft rack) with full documentation. I walked out of the donations meeting with the other curators today who thought it was a piece of s**t and didn't want to take it, calling it a 'dumpster fire' Art was a friend of mine. Hopefully it can go someplace where it can be appreciated. Talk to Tom about it, unfortunately, time is short.

More mystery recycler boards - DEC, Fujitsu(??), Cipher, Emulex

by jules.richardson99＠gmail.com

Hi All, My local recycler contacted me to say he'd had some more old boards come in. They're scheduled to be sent for processing next Wednesday, but in a couple of hours I'm heading out of town for a few days - it's possible I can rescue some of it next Tuesday when I'm back, so in the meantime comments as to whether anything is useful/important/etc. would be appreciated! Apologies for photo quality, in a hurry and the only vacant spot was the floor of the employee bathroom :-( __Digital boards:__ M8014 M8012 M8061 (x2) M8013 - I think the 8012 is a boot/terminator board, so that sounds handy. The 8061's and M8013 are disk, I think - do modern emulators of the drives exist? If they do, maybe I should snag the controllers? Not sure about M8014. http://www.classiccmp.org/acornia/ub/d1.jpg - terminal board? DB25F and BNC on one edge. There was another similar board with two BNCs and a DB25F which was marked "VT100 basic video" on the underside, so I'm assuming this is related. http://www.classiccmp.org/acornia/ub/d2.jpg - 8085 CPU, ROM, RAM etc. Rows of transistors which perhaps suggests motor control, i.e. printer? http://www.classiccmp.org/acornia/ub/d3.jpg - related to d2.jpg?? __Fujitsu boards:__ At least, the main ICs are Fujitsu; there's no indication who the boards belong to. These are standalone boards, not ones that plug into a backplane. My hunch is that they're logic board pulls from old hard disks or tape drives - i.e. they're just garbage now. http://www.classiccmp.org/acornia/ub/f1.jpg - 2x 50-way connectors, switch in corner. PCB marked "KGKM B16B-934C-003" http://www.classiccmp.org/acornia/ub/f2.jpg - 2x 50-way connectors. PCB marked "CZGM B16B-9240-001" http://www.classiccmp.org/acornia/ub/f3.jpg - 2 x 50-way connectors, 1x 60W, 1x 26W. PCB marked "CZFM B16B-9230-0010A" http://www.classiccmp.org/acornia/ub/f4.jpg - 2 x 50-way connectors, 1x 60W, 1x 26W. PCB marked "KGFMU B16B-9830-0010A" __Cipher boards:__ There are two of these: http://www.classiccmp.org/acornia/ub/c1.jpg I suspect they're from some form of terminal (or maybe printer?), and now that they're separated from the rest of the system they're just junk. Note that someone seems to have scavenged a bunch of power transistors (or something) from them. __Emulex boards:__ I don't think any of these are the exact same models as the ones I rescued a little while ago, so I've included them here - but gut feeling is that they're still just tape (i.e. not SCSI) and so they're not worth the trouble. http://www.classiccmp.org/acornia/ub/e1.jpg - 2x50W, 1x?? (I forgot to make a note). CU0210402 on the PCB, CS0110202 on the "main" IC. http://www.classiccmp.org/acornia/ub/e2.jpg - 2x50W. TC0210201 on the "main" IC. There were a couple of others too each with a 60-way and pair of 26-way connectors; I suspect those are SMD. Chances are good I'll end up rescuing the DEC Mxxxx boards on Tuesday "just in case", but if anything else stands out then please shout; gut feeling is that they're PCBs from things that would have been quite wonderful once when complete but are now completely useless to anyone. cheers Jules

I'm all over stuff like that.. especially with my TVT project. ?It has been a real slog finding correct looking vintage caps in particular. ?I wish I lived nearby! Sent from my Samsung device -------- Original message -------- From: Tom Gardner <t.gardner at computer.org> Date: 2016-09-06 4:18 PM (GMT-08:00) To: cctalk at classiccmp.org Subject: Components available Hi A friend of mine died recently; he was amongst many things an electronics tinkerer and has a closet full of small parts in bin cabinets (resistors, capacitors, ICs, transistors, hardware, etc.).? The ICs look mostly old. His wife and kids have no interest and would like to find a good home for these parts rather than recycle the lot. They are in Palo Alto CA Anyone interested in using them could just pick them up in the next week or so. Any other ideas?? Really hate to see these go to recycle.

Odd memory error in PDP-11/04

by ethan.dicks＠gmail.com

Hi, All, I've finally tracked down the simplest problems in my PDP-11/04 that's been sitting unused for many years (the one that we formerly used as a hardware test platform for Unibus COMBOARDs 30 years ago). The primary faults were a half-bad 7474 in the console (the flip-flop attached to the Run LED was not toggling when it should) _and_ an apparently bad DL11-W that isn't passing grant - for now replaced with a fully-functional module, but to be debugged later). What's happening now, since I can finally enter octal at the console, is when I change one location, 000000 for example, it echoes across multiple locations... To whit: I use the console to fill 000000 to 000040 with zeros, and verify they are all zeros. I deposit 177777 in 000000 and I get back the following... @L 1000 @D 177777 @L 1000 @E 001000 177777 @E 001002 004000 @E 001004 004000 @E 001006 004000 @E 001010 004000 @E 001012 004000 @E 001014 004000 @E 001016 004000 @E 001020 177777 @E 001022 004000 @E 001024 004000 @E 001026 004000 @E 001030 004000 @E 001032 004000 @E 001034 004000 @E 001036 004000 @E 001040 004000 @E 001042 177773 @E 001044 177777 I replace the 000000 at 000000 and get all zeros. So I appear to have two problems: 1) Depositing any value is echoed 000020 later. 2) Setting D10 in location 000000 results in D10 set in all the locations I have few spares for this machine. Lots of spares for my 11/34 (which I will want to test at some point soon), but this box (BA11-L) has a DD11DK not a DD11-PK, so I can't just upgrade in place. Does this sound like a dodgy CPU, dodgy RAM or both? I have this minimally loaded... M7263 PDP-11/04 processor M7847 16K MOS RAM (half loaded) M9312 with console ROM and papertape boot ROM (I have more ROMs available) M7856 - DL11-W strapped to defaults as a console/RTC many dual-height grant cards M9302 terminator UA-11 debugging board Oh... and I see while typing that it just started halting immediately after reset... so something just broke while it was powered on and running the console ODT. :-( I guess I'm back to low-level hardware debugging again. But in the meantime, any CPU/RAM symptom suggestions? I have the prints. I'm just looking for any "oh, yeah! That happened to me!" with "...and I fixed it by testing X and replacing the bad ones". All this so I can make a test bed for my M9313 boards and get them working again to fix the DWBUA on my VAX 8300... -ethan
