I have (2) I will be getting rid of soon. No k/b's (I know where you can get them though, if the guy is willing to ship). Both have h/d's, but neither will boot (as far as a quick test showed). Make offer. I also have (2) mono monitors, but have screen mold. Make offer.

You are truly dedicated using India Pale Ale to rinse your boards. The waste boggle the mi........ Oh ipa = isopropyl alcohol. Nevermind.

probably OT, but still cool: found an HP large format printer on the road

by chrism3667＠yahoo.com

Can't say anything other then it's in my car. It'll be the second "plotter" I've picked up for little or nothing (I was actually a good 10 miles from "ground zero" before I realized this thing is just a big ink jet printer, not a plotter). Anyway it should be good for making large format schematics and whatnot. Doesn't everybody love those? Anyone w/docs or drivers please contact me. Perhaps offlist.

I use cheap plastic ice cube trays to segregate screws and small parts by sub assembly.

Vax 3100 disk recommendation and suggestions

This used to be covered in the VMS FAQ. IIRC attempts to read or write to higher block numbers by the console firmware result in the address wrapping rather than an outright failure. It should be possible to arrange the files on a larger disk so that the code that the firmware needs to access for booting is located below the limit. However, this is not as easy as it sounds as VMS BACKUP restores files in alphabetical order and some of the critical bits are located under the VMS$COMMON directory which may end up getting written late in the restore. Special care needs to be taken of the dumpfile (or pagefile if used for dumping). A system crash will result in the firmware writing to it and this can be very bad news if part of the file is located beyond the limit which will cause the address to wrap and something near the beginning of the disk to get overwritten. Disks that are not used for booting or system dumps are not affected by this limitation so a system can have a small boot disk and a much larger data disk. Regards, Peter Coghlan.

Bitsavers rsync

by cc＠informatik.uni-stuttgart.de

The rsync daemon on bitsavers is still down, and noone seems to know the reason why. I've already got a request from someone using my mirror on a regular base... At least, one could expect a notice on the home page. Christian

For future reference

I've sold stuff to several cctalk list members over the years and I like to think it has all been pleasant. This evening I was accused by someone of shilling an auction for an XCOMP ST/S hard disk controller board set. I'm quite interested in your homebrewing efforts and I wish I had the space and money to buy some of your wares. Accusing people of impropriety is not the way to earn accolades. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?
