Well, with the help from members of this list I finally got one Series II running and one not tested but saved back and two that were FUBAR. So, because I cannot bear to throw anything away all at once, kind of like the story of the three legged pig, i decided to scavenge what I could of the two Series II before pitching them. I just pitched the Series I, the 3, and the 4. I saved anything that had a wire connected to it and put all the plastic, sheet metal and gear trains into the trash on the theory that the gear trains looked tough enough to not be a failure point. I saved about half the weight and half the storage space. The fuser bulbs looked to be in good shape so I don't think they were the cause of the "50 Service" error I was getting. At least the filaments were not broken. I am assuming that this is like a halogen bulb and you don't want to touch the glass surface of the bulb. Is there a recommended cleaning procedure??? Too bad the fans are 24 volt not 115 volt. I could have used some 115 volt fans for my Kilowatt Linear I am building. Are there any parts I missed? Are there some parts I should have dumped?

VAX 11/780 help needed.

by pat＠computer-refuge.org

So, I've got power run now, and am trying to get the machine up and running. After I figured out what baud rate it wanted (and reset it down to 1200 baud from 1800 baud), I've been trying to figure out a problem... So, when I connect a terminal to the console port, all I can get is an address: 173002, followed by an "@" (the ODT prompt). Trying to examine the addresses using ODT fails. So, it looks like the bootstrap PROMs are not accessible for some reason. From what I see, it appears that they are actually contained on the CIB (Console Interface Board) in the KA780 CPU. Can anyone verify this, or have any suggestions what I should check? The power supply bricks all have their "POWER NORMAL" lighs on, and seemed to have a good 5V output from testing with a dummy load and DMM. Any ideas? I'm a bit stuck here.

Classiccmp website?

by rigdonj＠cfl.rr.com

Anybody know what has happened to the Classiccmp website? I checked some of my webpages there yesterday and the files are still there but most of them are now blank! The files are NOT missing and they still have the right file size but they're blank. I just tried to access the site a few minutes agoo but now I can't even get a connection to it. I e-mailed Jay yesterday and asked him about the problems but haven't gotten a reply. Joe

IBM Book (VSE/ESA Performance Management and Fine Tuning) - anyone want?

by shirker＠mooli.org.uk

I found this in a book sale at a local organisation, and rescued it in case anyone's interested. If you want it, you get to pay me the 50 English pence it cost me, plus shipping from UK. It's by Bill Merrow, pub. McGraw Hill, (C) 1993. Has a flash "Includes VSE/ESA Version 1.3" on the cover. Ed.

Any Honeywell fans?

by dan＠ekoan.com

At a recent hamfest I picked up two sets of what appears to be Honeywell training material. Each set consists of a slide projector tray, cassette tapes, and a manual all in a fold-open case. The first set is labeled "Digital Computers and Software" and is dated 1979. It has 80 slides in the tray and comes with two cassette tapes and a booklet. The second set is labeled "Delta 1000 Control Interpreter Language" and is dated 1980. There are 46 slides in the tray and there is one cassette tape, along with a booklet. All of this stuff is marked "Honeywell Proprietary." I'm generally much more interested in HP stuff, but this looked unusual enough to pick up. Contact me off-list if you'd like more information. Cheers, Dan www.decodesystems.com/wanted.html

Osborne 1

by ddl＠danlan.com

To answer a few questions that have been asked about the Osborne 1: -I'm not asking anything for it, but neither will I spring for shipping and packing. I expect this could be expensive. I am not willing to deal with international shipping at all. -I'm in Gloucester, MA. Pickup would of course be best. -It worked last I played with it, but that was 15+ years ago. -The latches are on the sides. And to answer some questions that have not been asked: -The original user's manual is included. -There are a number of disks, but no originals. -I believe it has the double density controller.

Panasonic FDD number decode?

by cfandt＠netsync.net

Has anyone information on decoding the model number suffix on a Panasonic 3.5" floppy drive? The number is JU-257-14PF. I was told it was a 720K drive when I bought it some time ago but it seems to act like a 1.44MB unit. Need to confirm as I want a 720K for an industrial OS-9/68K system I'm thinking of dragging out of storage. Controller only talks 720K. Controllers in PC's use connector pin two, IIRC, to select lo/hi density. Is my drive selectable by internal jumpers for 720k only/1.44MB only (and is there such a drive available in general)? I don't care to hack the hardware on my nice OS-9 system just to make something work. I can find 900+ hits on Google at this moment for the JU-257. Several different suffixes are shown and many indicate 1.44MB capacity. There's but only one with the -14PF suffix which appears in the search under the inventory of Searchlight Tech.com site. No descriptive help there. Methinks this is in fact a HD drive instead of the desired 720K and I was, basically, ripped off. Neither Matsushita nor Panasonic website searches yield anything on even "JU-257". Long obsolete, evidently. Thanks for your help. -Chris F.

2114 Static RAMs...

Guess what the hurricane(s) left behind!

by Innfogra＠aol.com

I will be happy to pass on the SW when I get to it, and to all also.. ISIS should run on the 330, too. The 330s origianlly were 8086 SBC with separate disk controllers for the HD and 8" Floppy. The 330 had a Priam 3450 *" HD (30 meg) and a DSDD 8" floppy and a 6 slot backplane. My 380 has a 286 SBC with a 14 slot backplane in one box and the HD, floppy and a tape drive in a second same size box.Twin 50 pin cables interconnect. The combo HD, Floppy and tape card is the 214 I think. There is usually a console port on the SBC. Other serial IO was on other cards. The hard drives have a manual parking lever. If it is not set do it immediatly. I would love to hear what the configuration of them is. The SBC board numbers had a slash number. 86/30, 286/10. The 320 is multibus II isn't it? A VME type connector (but not the same pin configuration). Paxton
