building a PDP11 from the things you find at home

by pjschilling＠gcstech.net

I think Bill's got this one on the nose. A re-incarnation of Next. Maybe the industry is more ready for it this time around :>) Phil -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Bill Bradford Sent: Saturday, July 28, 2001 8:01 PM To: classiccmp(a)classiccmp.org Subject: Re: building a PDP11 from the things you find at home On Sat, Jul 28, 2001 at 03:38:46PM +0100, Iggy Drougge wrote: > Personally, I think there's too much UNIX in OSX.

Extra copy of "Apollo Computer" book by Hall

by rcini＠optonline.net

Hello, all: For those interested, I seem to have found at home another copy of the history of the Apollo guidance computer book by Eldon Hall, speaker at VCFE. I purchased a signed copy from him today because I thought that I didn't have a copy at home. Surprise! So if anyone is interested in the *unsigned* copy, I'll let it go for $35 including shipping. I paid $45 for the signed copy and bought my first copy on Amazon for about $55. Again, interested parties please contact me off-list. Thanks.

Sun 3/110 is alive!

And a significant departure from the [otherwise reasonably consistent] Sun numbering scheme. A darn good design, in my opinion. -Dave McGuire

OT: Humor Moving to Florida -- VERY FUNNY!!!

Though I've lived in the Washington DC area now for about nine years, I've lived in Tampa for a while, and I have a house (a rental property) in Treasure Island...Every day of the Washington DC summer that I sweat and choke through leaves me longing for Tampa Bay weather. Nowhere near this hot in the summer, nowhere near this cold in the winter, and a certain lack of bullets flying overhead makes it so much more...relaxing. -Dave McGuire

Booting A PDP-11/23

by univac2＠earthlink.net

I recently found a PDP-11/23 (Model 11C23-FE) at Goodwill. It is in a tall slim tower style enclosure, has a dual 5.25" floppy disk drive, a hard disk, and 1024KB. It passes the memory test, and trys to boot from "DU0". The light on the hard disk comes on for a few seconds, and then I get the message ERROR UNIT DU0 ERR 13 DRIVE NOT READY WISH TO REBOOT [Y,(N)]? So is something broken, or am I just doing something wrong? Any help is greatly appreciated. Thanks, Owen

Any help is >> greatly appreciated. First is there a hard disk drive there???? If there is start with Tony's suggestion of checking the enable and ready. IF not, you'll need a drive maybe. Do either of the floppies or their lights become active???? If they are it's looking for bootable media and there is none. The other possibility is the drive(s) is/are disconnected or maybe plain DOA. Allison

cipher f880 dosc

by wrking＠dadaboom.com

Does anyone know where an online copy of the cipher f880 docs might be found? What I really need is the definitions of the switch settings internal to the drive (which one controls parity?). Thanks, Bill

Free in DC area: Fuji SMD drives

by CLASSICCMP＠trailing-edge.com

I've got 5 Fuji 8" SMD drives (M233x and similar) just inside the DC beltway (I-495) available immediately. You pick up only; I will not ship these (weight with power supplies is 35-45 lbs each). They all worked about three years ago, the last time I fired them up. Anyone hauling them away also gets my collection of Emulex SMD controllers and Fuji SMD manuals, and the rack mount slides/trays, and whatever else I feel like making you take. Also available are some 8" Pertec voice-coil floppy drives, in "parts only" condition. Manuals and some Pertec-specific test equipment are available too. Again, you-haul. Email if interested; first-come, first-served. Tim. (shoppa(a)trailing-edge.com)

Free in Austin, TX: PDP-11 equipment

by mrbill＠mrbill.net

I've got the following PDP-11 equipment free for pickup in Austin, Texas. David Williams from Houston has first shot since he is coming to pick up some uVAX-IIs, but anything else left is fair game. If you come get something (email me first!), you have to promise that it wont be scrapped or the front panels sold on eBay for some rich CEO's wall collection. I'd like it to all go to good homes where it will be appreciated. (god, I sound like an animal shelter) - PDP-11/60 and UNIBUS expansion cage (and some maintenance printsets) - two RX01's - one RK05J If anyone is interested, please email me. This stuff CAN NOT and WILL NOT be shipped - i cant even get some of it out of the crate I got it in. 8-( Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

building a PDP11 from the things you find at home

by dittman＠dittman.net

> Don't you think it strange the bidding went from $50 to $600 in one bid? > When $50 seemed to high? > I smell a wumpus, or a rat! I've seen this happen a couple of times. Someone that really wants something will put a very high bid in, knowing that no matter what happens the eBay bidding mechanism will automatically up their bid. Someone else that really wants the same thing will then come along and put in a very high bid. This causes the bid to automatically shoot up to the lowest of the high bids. Fortunately I don't bid this way. I only bid what I'm willing to pay and that's it. -- Eric Dittman dittman(a)dittman.net
