Available (NL) : Apple Mac shtuff

by waltje＠pdp11.nl

Hiyas, One of my customers finally saw The Light, and will now allow me to free up some of the storage space we have there. Aside from me being quite busy chucking stuff out into the dumpster, there's also a bunch of Apple thingies from their DTP department that can now be dumped. Obviously, I will not get caught playing with fruity "computers" during *my* lifetime, soo.. available are: - Mac II SE - Mac IIcx - Mac something (couldnt read; too dark there) I also know there are several Powermac (what? can we eat that?) boxes up that shelf, just couldnt be bothered climbing up there in the dark, any more details will have to wait till later, when I first grab a lite 'fore going up there. Since shipping fruit internationally can be quite expensive (gotta keep it cool 'n stuff) we'd prefer to have it picked up by local people (meaning, Dutchies) or people silly enough to drive a LONG time for a bag of this fruit..

HP-85 consumables.

by netsurfer_x1＠fastmailbox.net

Hi all! I'll be getting an HP-85 before the month is out & I was wondering where I could find a source for consumables (tape cartridges & thermal paper specifically) for this machine. Any info would be more than helpful. -- David Vohs netsurfer_x1(a)fastmailbox.net -- http://www.fastmail.fm - Choose from over 50 domains or use your own

HP 7906 drive lives again & stuff

by jwest＠classiccmp.org

After suffering a head crash on my "new" 7906, I decided I REALLY should have taken the time to clean the filter and the blower squirrel cage and air ducts better before using it. That was done, then the drive wouldn't seek past load point. So I swapped all the cards in the drive card cage with a "spares set" and now the drive is working wonderfully again, passing all diags. It is SO nice to not rely on a single 7900 drive anymore! Word to the wise - lesson learned - never skimp on dissassembly/cleanup of an old style 14" drive. Take the time to get every last piece of dust & debris out! Over the next few weeks I will be cleaning, refurbing, and testing all the other 7906 drives I have. Once I get all working that can be made to work... I will have some known working 7906 drives available for trade, as well as some 13037 controller boxes. Might not have spares of the 13037 pca that goes in the host though. If anyone is interested, let me know. Keep in mind these drives are somewhere in the neighborhood of 200 pounds each. I may get my 7905's working too but not sure I want to give those up just yet. Also - the only way I found to clean the squirrel cage blower was to take it out and clean each fan blade by hand and with a toothbrush. The very fine dust that makes it past the secondary filter cakes on these blades and is very hard to scrub off - it's like concrete. Does anyone have any ideas here? I was thinking of soaking the blower in something to loosen the dirt, but it's unfinished metal and might rust. Any thoughts? Regards, Jay West --- [This E-mail scanned for viruses by Declude Virus]

Strange Qbus cards: Data Systems Design and Marconi

by TRASH3＠splab.cas.neu.edu

The DSD 880 Qbus subsystem used two different cards, the 8832 and the 8836. The connector near the handle is 26 pins. For the 8836, the 16Mhz crystal is in location G9, with the model number of the board on the edge above that, for instance 808836-05 rev K. There are socketed 24 pin dips in row e, and headers for programming in D4 and F5. There isn't really any special software for basic use, but if you want the double sided use of the floppies, then you have to either use their drivers, or patch your own. The same goes for utilizing more than the 2-RL02 emulation feature, you have to patch for more logical units. The board has a bootstrap for either the floppy or the hard drive. I could look up what is in the 8832, but it is probably pretty close. Also, the dual height board for the floppy-only DSD440 subsystem is similar, but I have the board for that at work. I still use a couple of the DSD880s. The system came with a diagnostic floppy which complemented the front panel, but I haven't used it for a long time. We used to use the DSD880 along with a VT103 and 11/23 in test equipment that a company I previously worked for sold. Hope that helps, let me know if you (or somebody else) needs/wants more info on the 880 series. Joe Heck, K1LBG

HP 7906 drive lives again & stuff

by freddyboomboom＠comcast.net

Sorry I don't have any clue to help you on the squirrel cage. But the one thing I wanted to mention to you was to disconnect the solenoid that controls the heads moving out when testing the disk packs. We had a case where a bunch of disk packs were stored in a hot muggy environment for about 9 months or so, and warped on us. When spun up, the disk will make quite the shrill noise indicating it's warped, and if you don't disconnect the solenoid, the drive will crash all over again. I haven't worked on one of those drives in about 10 years... TTFN Andrew

Ref needed for PCjr ROM cartridge Kit

by nampcjr＠yahoo.com

I obtained a nice supply of PCjr ROM cartridge Kits from Integrity Software. The carts were in a box in the corner of their warehouse, and was all they had left of their past enterprise with them. I looked in a Nov 1988 issue of the Eugene PCjr Club Newsletter and there is mention of the cartridge being used for backup. One thing missing from my shipment, though, were the docs needed for the soldering to change the settings on the physical PCB after putting on an EPROM. The title of the doc was "PCjr ROM Cartridge Kit Technical Reference Manual" and had a file name of RC-TECH.REF . If anyone happens to have this, write reply so I can get these puppies working!! Much appreciation! Brian --------------------------------- Do you Yahoo!? The New Yahoo! Shopping - with improved product search
