[catching up a bit] > Ideally though you're going to need to determine the model of HD, and get > some extras. Ideally, yes, but I've found that's not always required in practice (in admittedly limited experience). I've successfully dd'ed a couple of old SCSI drives to larger SCSI drives and was able to boot & run without issue (other than the wasted space). I suspect it works because SCSI hides many low-level details. I certainly didn't test all the boundary cases, so there certainly might be gotchas if you used the duped disk extensively or in production. On my VME532 machine, I dd'ed the ~150MB Maxtor ESDI drive to a ~300MB Maxtor and it boots fine from the larger, half-wasted drive. I wouldn't count on it working with another vendors drive, or for all permutations of ESDI controllers. YMMV. Ken

Victor 9000 boot floppy, was RE: laptops and 5.25 inch floppy drives?

by aek＠bitsavers.org

> I've just uploaded scans of the Tech Ref and several other tech docs > to http://bitsavers.org/pdf/victor/victor9000 I just noticed that the figures are all missing in the tech ref. Most wouldn't matter, but the sector format of the floppy would be nice to have documented. Does anyone have the details of this (actual sync pattern, etc.)?

Hi folks, I received an email from an individual who is looking for someone to help fix their 8/E and possibly their paper tape punch unit.

wall wart for TI-58-C

by mtapley＠swri.edu

Bob et al, the plug is polarized, so I assumed there's diodes in the wall-wart. Mine (TI-59, should be same) is at home and I'm not, so I'm not able to give better first-hand info before tomorrow, but http://xgistor-echo.ath.cx/files/TI59/ has much useful info. I commend the TI59_PSU.zip file to you in particular. Let me know if you want measurements off of my wall-wart(s). I think I can arrange that.

Cleaning House

I probably should mention that stuff has been sold at VCF that was originally listed on VCM. I tried to remove most of it from VCM, but there are still a few items that I missed. My apologies for any inconveniences there!!! Marvin

Cleaning House

by marvin＠rain.org

It is looking more and more like I'll have to move and thus have a ****<<<LOT>>>**** (ask Hans) of stuff that needs to be tossed, sold, or stored. I'll be putting stuff on VCM and Ebay to 1) see if I can still make enough money to buy this house, and 2) reduce the clutter :). This will be a continuing effort for the next several weeks and I'll be listing more stuff daily. Off topic for VCM and maybe of interest here, I have a couple hundred Belkin NOS Cat5 (not Cat5/e) cables w/RJ-45 ends. They are bagged as 10 sets per bag and I have 30", 42", and 48" available at $10.00/bag plus $6.50 Priority Mail US shipping. Email me offlist if interested. Check out VCM and Ebay (ID=KE6HTS) for the stuff I am getting rid of. Thanks!

floppies

by aek＠bitsavers.org

> what's the expected > remaining lifetime of a floppy? Time is probably of the essence Chuck and Fred have more experience, but I'm assuming once they're in a stable temp/humidity environment they should be ok for another 10 years. The stuff I'm dealing with now is stuff WAY past its shelf live (20-30 year old tapes). I've read hundreds of floppies over the past five years or so, and the only problems I've had have been with 70's 8" media that was stored in poor conditions where the oxide strips off upon head contact, and the common problem with all head-contact media of oxide/binder buildup reducing the signal level off the head. I absolutely agree that the discs should be copied in image format.

Interesting, but who needs this kind of stuff > anymore? Someone who still owns one of these devices. Really more of an issue for software for test equipment, though, since that kind of stuff has a longer useful life (assuming the floppy for it doesn't get lost..)

The important thing to preserve is their contents.

Looking for older Cisco PIX-520 images

by ethan.dicks＠gmail.com

I have this recently acquired PIX-520 with what seems to be an entirely *blank* FLASH boot card. The machine is so clean inside - not a speck of dust - that I think it may be a NIB unit that someone decided to disgorge onto eBay last summer. It goes through the usual PC-ish boot dialogs (there's an Intel Pentium board inside, with 3 Intel NICs and a 3.5" floppy as the only peripherals besides the boot board), but when all the PC stuff is done, the unit acts dead - no traffic on the serial port that I can see, no text on the (installed by me for debugging) video. I'd try the Cisco site, but besides lacking a current log-in, from reading some of the firewall mailing list entries about older PIX OS files, it seems that Cisco may have purged some of what I'm looking for. If anyone happens to have any archived files from older versions (pre 6.x) of PIX OS and the attendant boot helper files (secondary bootstraps), please contact me *off list* if you are willing to share. For starters, I'd love to find a file like bh510.bin, bh512.bh or bh514.bin, which are various versions of the "boot helper" for the less-obsolete versions of the OS. If I had a boot helper file written to floppy, I should be able to at least see some activity related to it _trying_ to install the OS. Thanks, -ethan

Fwd: Microvax IIs in BA123s

Id: <9zyoh.8847$w91.8571 at newsread1.news.pas.earthlink.net> --------- Greetings. I have a couple of MicroVAX II systems in BA123 boxes I would like to sell, hopefully to hobbyists rather than the local scrap guy. My question is whether it might make more sense to just pull the boards and cabinet kits, and scrap the BA123 enclosures. The first system has fairly standard components, a KA630 (M7606-AF), two 4MB boards (M7608-BP), a pair of DHV11s (M3104), a DELQA (M7516), RQDX3 (M7555), TQK50 (M7546), RD53, TK50, and a pair of boards from Ultimate Computer Corporation. I think the second system has some more interesting parts, like a pair of ESDI dives and a Pertec tape drive interface. The first system weighed in at 125 pounds, which would cost upwards of $150 to ship across the country from (from the Los Angeles area). I just do not know if there is any demand for the old BA123s in the hobbyist community. Opinions? Jeff. P.S. Apologies to the PDP-11 groups for the crossposts. P.P.S. This old DEC hardware amazes me. I hooked a VT220 to the first system described above, and powered it up. It booted right up with MicroVMS V4.7, circa 1987. -- Jeff Shirley spamalot at mindspring.com "Bill Gates is filthy rich, but that doesn't mean I want to be married to him."

replacing a dc005? (qbus chip)

by brad＠heeltoe.com

One of my rqdx3 boards suffered a trauma in a previous life and one of the "DC005" chips at the bottom cracked in half. Needless to say the board does not work. I removed the old chip, but what now? Does anyone have a spare DC005 or know of a suitable replacement? I assume this is one of the magic DEC chips for qbus. I suppose I could try extracting one from another board, but that is pretty painful... dips are easier to get out if you can snip their leads. -brad

Bummer. > Just what do you use for a termial with the SBC6120? For times when I need to move files (like programming the Flash on my IOB6120), I use a Linux box and Kermit and whatever keyboard is on the Linux box (laptop or desktop). For real terminal use, lately, I've been using mostly LK201s on DEC terminals, and whatever keyboard is handy for my Planar ELT-320, a 9" orange-screen electroluminescent wee terminal that takes both PS/2 keyboards and DEC LK201 keyboards. Since the terminal is so small, I like to use my Happy Hacking PS/2 keyboard with it - the whole arrangement is smaller than many laptops. The heaviest part is the slug of metal in the base of the terminal to keep the screen from tipping over (I also have a wall-mount case for another ELT-320 with no base). So... depending on platform, a DEC LK201 or some random PS/2 keyboard (Keytronics are nice) -ethan

Mouse for Tektronix 4105/4205 terminals?

by legalize＠xmission.com

I didn't know this until I acquired some of these, but the keyboards have a mouse port on the back; it looks like a standard serial 9-pin connector and it has "MOUSE" labelled above it. However, I have yet to find any documentation on the pinout or electrical/comm specifications for the mouse.
