is it a dps 6 or 8? In a message dated 9/24/2015 12:10:41 A.M.

I took the boards out to inspect them tonight (they had rattled about a bit during shipment) and everything seems ok. I'll have time to take some pictures this weekend. Unfortunately, somewhere along the line someone disconnected nearly all the ribbon cables running to the boards and I've got no idea what goes where (only a couple are cohesively labeled.) This thing is going to be a project. - Josh

Somewhat OT: Freighting Items

by cctalk＠fahimi.net

I know this is a topic that comes up quite often and I have archived a number of threads. However, I am still not finding what I need. The back story is that I need to have a desk shipped across the country to me. The desk measures 28" long, 27" wide, 35" tall and is ~125 pounds unpacked. While it is possible to disassemble the desk I rather not. I've gotten quotes form a number of outfits as follows: 1. UPS: $1200 to pack/crate the desk and ship it. 2. Craters and Freighters: $895 to wrap in PE Foam, Styrofoam, bubble wrap, and box shipped door to door (i.e. not real freight). 3. Freightquote: $475 if I palletize it/pack it myself (have to clarify if this is door to door or do I have to drop off and pickup). Anybody else have other suggestions/recommendations? From what I understand this desk is not that heavy (in the freighting scheme of things) and would easily fit on one pallet and maybe even a half pallet. But I've never shipped something via freight so maybe these are all accurate prices. Any help/guidance is very much appreciated. Thanks. -Ali

ISO: FP11-F (M7093) for PDP-11/44

by derschjo＠gmail.com

The 11/44 I acquired recently has a complete CPU set but no FP11-F board (M7093). I'd like to be able to run 2.11BSD (or other UNIX) on this machine, so having floating point hardware is pretty essential -- anyone have one going spare for sale/trade? Thanks as always, Josh

Backups [was Re: Is tape dead?]

> From: tony duell > In some cases it should be possible to write a machine code program > that executes on 2 processors with wildly different instruciton sets. I have this bit set that I was told (or something, the memory is _very_ vague) that early versions of the KL-10 had this hack; the root block on the disk was the boot block both the PDP-10 and the PDP-11 front end machine, and the first instruction or two was very cleverly construced and sent the two machines different ways. Alas, I looked in the front-end PDP-11 code (in the KLDCP; directory) and saw no signs of this, so maybe it was an urban legend? Noel

I would guess it would be incredibly hard to make a "disk" virus that would work on greatly differing OS's like Linux AND Windows. No telling what would happen if one of these disk viruses got onto a hard drive on a Windows system and then the drive was reformatted and loaded with Linux. Most likely you'd have odd crashes or something. Jon

I don't know what you're looking at for the front end of this project, but have you considered SQLite for the database engine back end? If not, you might take a look at www.sqlite.org - it's an extremely nice bit of software, if not for this project, then perhaps others. ~~ Mark Moulding
