Great end to week

by jrkeys＠concentric.net

Well Saturday was apretty good end to the week for me and the museum. At goodwill I found a HeathKit Educational system ET100 Learning computer with kb and cable for casette recorder. Also had with it the assembly manual and a memorex tape with some sort of programs on it just reading the hand wriiten label. The bottom was signed by Jay H. Jarrett VP Product Development and the person who put it together and dated 11-26-83. At used/new dealer I got the following 5 ea Duo Dock stations with bad ps's HP 2392A terminal users manual Itermec penlight bar code reader Memories, Micro-processors, Consumer Circuits, Industrial by MOSTEK 1975. IBM 3151 ASCII display station models 11,31, and 41 guide to operations. TI Application Report TMS 9900 system Development manual 1976. Honeywell IPC627 minicop user manual Mostek The F8 Microprocessor Preliminary Databook March 1976. Signetic's Designing with Microcomputers 1976. TMS 1976 Capactive-touch keyboard Interface Circuit manual 1977. HP Laserjet IIP has jamming problem needs some work. A BCC black notebook by Northgate for $19.99 needs some work. A ZEOS hand held unit for parts $9 black case no screen. Other items not ready for 10 year rule but it was a pretty good haul for a slow day. Keep computing John

HP 150 stiffies

I think I remember knowing it at one time, at least well enough to fake it when I needed it once -- though whether that was through reverse engineering the file format or looking at a co-worker's ISV kit manual I can't recall. > What about doing a plain sector copy on a PC or something? The disk is a > standard double-density one so a PC controller should be able to read it. > Shouldn't be too hard to figure out what sectors are used and copy them over. Sydex has a shareware device driver that is supposed to let you use HP150 stiffies directly on a PC-compatible. I tried it a few months ago on a non-classic (hmm, 7 years to go) Toshiba notebook but it was not able to read the lone 150-formatted stiffy I had handy. Whether that is because of newfangled hardware, funky notebook hardware, inability of the software to handle single-sided stiffies, or bad vibes I don't know. I am able to read the disk in a 9114B on my Portable Plus though. Hmm, maybe I'll try DISKCOPY on it tonight and see if that gets me another stiffy that the 9114B can read. Cheap thrills. -Frank McConnell

PLease ID CD-ROM unit

by maxeskin＠hotmail.com

I have a CD-Rom unit here at my school that needs to be identified. We don't know where we got it, and have no docs. All we have is the external box, about 6" X 15" X 2". It is labelled "DATEXT CD-ROM DRIVE UNIT", and on the back says "MODEL DTX-10" and was made April 1986. It has a centronics plug on the back. The card that came with it has a single female socket,37 pin. It is labelled CD-IFI3, and has an NEC D8255AC-5 chip on it. It is a standard 8-bit ISA. Could someone tell me how useful this thing is, what drivers I need, background on it, etc? Thanks ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Osborne Executive (fwd)

by rws＠ais.net

Hi all- I received this message, and I can't help as I don't have an Executive (just a 1). Can anybody offer any ideas? You can either reply to him, or to the group and I'll forward them to him. Thanks, Richard Schauer rws(a)ais.net ---------- Forwarded message ---------- Date: Mon, 11 May 1998 11:44:10 EDT From: JWMc33 <JWMc33(a)aol.com> To: rws(a)ais.net Subject: Osborne Executive I have three Osborne Executives, all of which give me fragmented type on the screen when I turn the computer on. A friend suggested that I need to change "the batteries." I can't find them. Can you help me? John McCormick

There's the rub, I think Doug is trying to copy a stiffy with installed applications and he wants the applications to be "installed" on the copy too. My vague recollection is that an "application master disk" is supposed to have a file that tells PAM about an application -- things like what files need to be copied for installation, what text to put in the application's block on the PAM screen, and what to run to when the user wants the application started. Installing the application gets the files copied and the other info stashed in some file (maybe a hidden one) that PAM keeps in the root directory of the boot volume. That latter file is probably what Doug needs to copy to his new boot disk. Of course it's been umpteen years since I last thought about this and so I don't remember the filenames. -Frank McConnell

Amongst the ACONIT collection (see previous message), I found a Xerox workstation. Its a desk side, brown tower case with a separte small box on top containing a 3.5" floppy drive. It has a large (21") screen and optical mouse. It is made up of 4 tall boards wth part numbers like 140K0xxxx where xxxx are digits. Can anyone id this system? Regards, Hans B Pufal

Saved my bacon...

More PDP-11 tricks... (How many amps did you just say?)

by DSEAGRAV＠toad.xkl.com

I've managed to blow some obscure breaker somewhere, so now the CD head gets to decide if I get to haul my PDP-11 elsewhere. I'm not allowed to turn it on for the rest of the week, or until I find out how many amps it pulls, pray to the goddess Apthrodite, offer burnt 95 CDs, etc... Anyway, I've produced the following: I have 2 BA-11 boxes plugged into a 861C power controller, a RA81, a RA92, and a 9-track drive rated at 2 amps. Also, a TU58. How many can this pull running, and how much does that *%%%#& RA81 pull when started? Note that the 2 BA boxes are on the 861C, everything else is in the wall. -------

Calculator displays

Amazingly, there is a good image of it on the website. My last request is therefore redundant. Thank you one and all. Philip.
