Anybody have any interest in a VaxStation 3000? Looks clean, no monitor or kbd. BTW is there a faq about hooking up a VGA monitor to a Vaxstation video connector? Regards, George

Here's the guy in India again. I doubt anyone will jump on this offer, especially after Lawson's incredible tale of Indian customs malfeasance, but if you do get it, I'm sure it'll make for a very entertaining story.

HP 7980S 800bpi option?

I have one of these drives, and am very happy with it. It would be even better if I had a manual :) But, seriously. I am (desperately :) looking for this 800bpi module for the drive; I have the XC option which I'm willing to remove in favor of the 800bpi module. Does anyone here have an option part number, or, even better, the option itself ? *help* [squeeky-voice scream] --fred

I actually saw that guide today. The main difference is the amount of core memory the backplane will support, and, hence, the backplane slot layout for the system. It is VERY important to know which kind of backplane you have, otherwise, damage to the boards WILL occur ! You can just slide out the backplane from the cage, and read the ID on the sticker. --fred

VGA screens on.. (was RE: vaxstation 3000?)

I was able to dump all DEC single-frequency tubes by getting some IDEK (Iiyama) 17" color monitors which have both VGA and BNC (3 and 5, SOG supported) ports.

New find: pdp-11/05

by robinm＠rpi.edu

Hello, Today a friend of mine acquired a pdp-11/05 from our school's engineering department. Unfortunately, it isn't in too good shape. Fortunately for him, I've spent the last three years restoring (sucessfully!) a pdp-11/45. So I offered to help. However, this machine is somewhat of a different animal, so questions: Could someone scan the engineering drawings for an H217C stack? This is partly for my own edification (I have one such board in my machine), and partly because of the fact that this "new" pdp-11/05 has no core with it. Its engineering drawings seem to indicate that it wants 4 or 8kW of core (one or more of H213-H216), *not* the 16kW of a H217. (Granted, by placing two H214s into a chassis we get 16kW, but I digress.) That would have been enough to shut me up, but I looked a little further. It appears that the H213 (4kW) stack is a proper subset of the H214 (8kW) stack. The schematics appear to indicate that the H214 has all of the lines, bus connections, etc. as the H213, plus a few more. Indeed, it appears that if I were to place an H214 in the machine, but tell it that it was an H213, it would be fine (and see 4kW of course). Am I right? If so, the next question is, can I do this with an H217? (Drop in an H217C, and tell the machine that it's really an H214/H215.) This might sound like a gratuitous waste of core, which it is, but I happen to have another core board (not in my machine) that could be used... So anyway, the engineering drawings would answer this question really fast. If not, I guess we'll be looking for an H213-H216... :) Thanks, Michael Robinson RPI Electronics Club Vaxherd/PDP-11 Fixer robinm(a)rpi.edu

Thats a general problem on Ebay, seller tend to cover their listing-costs into the "shipping" or "handling" fees they charge. Your only chance to make this clear is a mail to the seller on this before you bid. Make clear that you will only bid if the seller follows the rates of e.g. USPS or some other shippingcompany. Then you have the choice to take or to leave it. >I called the local locksmith and they will duplicate this type of key for >$6 each.

IBM drives in a Kaypro

by cb＠mythtech.net

>I kind of hate to ship off my hard found, and not likely to find many more >IMB drives, anything else yall can think of I could safely offer this >person for his kaypro? Any old full height 360k drive perhaps? I have some half height 5.25 360K drives. They are working pulls from PC clones. I don't think I have any full height ones. Some (most?) are black, and many have that little imprinted asterick that designated the 360K "B" drive as opposed to the 1.2MB "A" drive. I don't know if these are IBM branded drives however, as many were probably NOT pulled from actual IBM PCs (some might have been). If you want one, just let me know. -chris <http://www.mythtech.net>

Kaypro II

by Robert_Feldman＠jdedwards.com

Because of a peculiarity in the Kaypro format (Fred Cisin has gone over this before, but I don't have the details at hand), you must format the Kaypro disk on your target PC for it to work. This formatting can be done on a PC with programs such as Xenocopy, MediaMaster, Convert. The disk formated on the PC can then be used in the Kaypro. You can copy files from native Kaypro disks to this disk, then read it in the PC with the software. -----Original Message----- From: Mike van Bokhoven [mailto:mike@ambientdesign.com] Sent: Wednesday, February 12, 2003 6:03 AM To: cctech(a)classiccmp.org Subject: Kaypro II <snip> - Does anyone know if it's possible to write Kaypro disks with a PC and 5 1/4 inch drive? If not - any hints on where to dig up software? <snip> Mike.

Sun tapes

by aw288＠osfn.org

I have a bunch of old Sun tapes I need to get rid of, as I no longer run any Sun-3 or Sun-4 machines. Most of these are real Sun distributions (although they look cheesy) of SunOS 4.1 and 4.1.1, plus SunLink and Openwindows. There also might be some third party stuff. I think all of these tapes actually have data on them, but I no longer have a suitable tape drive to verify them (so maybe expect a few to be flakey). Anyone need these tapes (about 13 1/4" QIC-24, I think) for cheap? For the lot - $8 plus shipping for 10512? I thik I also have quite a few unused 1/4" tape carts, also cheap. Real cheap.

Differential SCSI vs. SE ?

by Fred.van.Kempen＠microwalt.nl

All, Now that I inherited a nice set of StorageWorks enclusures with an HSZ40C controller, I might as well use it, no? I plan on connecting it to the primary file server of my "fun" network (also known as VAXlab, aka pdp11.nl) so I'll have more (and safer) storage there. Only prob is.. the HSZ40C has a diff-scsi port, whereas the machines have SE. Is this easily converted with a cable, or will I be doing resistor- balancing and/or use a signal converter box? Thx, Fred
