Coming up dry for Alps/Radio Shack/Atari/Commodore plotter g ears

by Robert_Feldman＠jdedwards.com

Allied Devices (http://www.allieddevices.com/web2000/documents/pinhubgears.80.120.html) lists 120 pitch gears. Making a die (internal cuts) is probably harder than machining individual gears. -----Original Message----- From: Ethan Dicks [mailto:erd_6502@yahoo.com] Sent: Tuesday, April 22, 2003 10:13 AM To: cctalk(a)classiccmp.org Subject: Coming up dry for Alps/Radio Shack/Atari/Commodore plotter gears Having worked out the pitch of the broken drive gears (120), and having looked on a couple of web sites _and_ contacted someone at Boston Gear, it's looking grim. According to the e-mail I got back, Boston Gear doesn't carry anything finer than a pitch of 64. When I asked who did carry such gears, the answer was: "I am not familiar with any company that makes miniature gearing." :-( My goal all along has been to find a company that has a bag of these on the shelf. I had no idea it was such an unusual item. I don't relish the idea of fabrication, but maybe that's what we're facing. Rather than machining each gear, I wonder how hard it would be to make an extrusion die to pump out a long gear and cut it into 5/32" slices? -ethan The New Yahoo! Search - Faster. Easier.

HP storage formats on ss80 protocol disks

by Innfogra＠aol.com

Ditto; I have several drives and would like to interrogate them. I also just picked up a HP ISA HPIB card at Goodwill (inside a Compaq Deskpro XE 466). It would help. Thanks a lot for developing the concept and prelim SW. Paxton Astoria, OR

PIP problem solved on Apple ][ CP/M

by vcf＠siconic.com

I was finally able to devote some time to my Apple CP/M issues and figured it out. It turns out that the version of MS CP/M that I'm using has got the device identifiers correct, even though Steve Hirsch warned that they were reversed in Microsoft's implementation. I apparently have a version where it is fixed. I first connected up my laptop to the Super Serial Card in slot #2 and then tried to PIP RDR:=B:file. I got a message to the effect that the RDR: device cannot be written to. Then I tried to get slick and use STAT to change the RDR: device to what PUN: was pointed to. That didn't work. Then I decided to just try PIPing to the PUN: device and it took, but I didn't see anything across the serial port. A little more digging and reading and I verified that, as Steve said, the Apple ][ CP/M standard is for a serial card in slot 2. In fact, the documentation I read indicated that the hardware configuration pretty much matches that of Apple Pascal. So I did a STAT DEV: to show me what devices were connected where. RDR: was set to PTR: and PUN: was set to :PTP (presumably Paper Tape Reader and Paper Tape Punch respectively). So then I did a STAT VAL: to see what the possible connections were for each device. PUN: could be TTY: PTP: UP1: UP2: I thought for a second and then figured it would be worth a try to see if UP2: stood for the device in slot 2. Sure enough it did, and when I tried a PIP to PUN: it worked. So I was able to PIP the files directly from disk over the serial port to my laptop. Very convenient. There apparently is a utility that allows you to copy files from CP/M disks to Apple DOS disks but it must have come on a DOS utility disk that I just don't have. I'm sure KERMIT or some sort of X-modem protocol was written that would have made this a lot easier, but I seem to have misplaced my Apple CP/M disks. Oh well. At least I know how it's done, and this can serve as quick docs for someone attempting to do the same in the future. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Odessey 1 (was Re: Fw: Game console up to $200)

by cb＠mythtech.net

>I've had one these since I was a kid, but I've never seen the rifle >or the boxed games before. I've never seen boxed games, but then A: I was pretty young when I used to play with mine, (and I believe it predates me in existance), and B: I have a feeling mine was never obtained via the market, but rather as a test item directly from Magnavox, so it may never have been complete with market packaging (I know I have a white labeled box that the system and controllers and stuff goes in, I'm assuming that was standard packaging). As for the rifle. I don't remember everything it was used for, but I know I LOVED the haunted house game that used it. There was a haunted house overlay, and basically "ghosts" appeared at various windows and doors and you had to shoot them. (IIRC, the ghosts were nothing more than white blocks, but hey, for early 70's that kicked ass!) -chris <http://www.mythtech.net>

HP 5036A microprocessor lab

by distante＠teleline.es

Hi Stuart, I'd seen your ad at: http://www.classiccmp.org/pipermail/cctech/2003-January/009065.html asking for the manual of the HP 5036A microprocessor lab. Have you got it ?? I also have one and also searching for a manual. There's no way to find it. Cheers Jose Madrid-Spain

US Gov't/Navy DEC clearout

by alanp＠snowmoose.com

DRMO is the group at a US military base responsible for taking care of surplused equipment. Some of it ends up being auctioned, for example, through web sites like www.govliquidation.com. Some of it ends up disposed of as scrap. alan ---Original Message--- From: cctech(a)classiccmp.org To: cctech@classiccmp.org,cctalk@classiccmp.org Date: Thu, 20 Mar 2003 10:05:15 -0000 Subject: RE: US Gov't/Navy DEC clearout Hi folks, Got this from a contractor working for the navy; how he found me before he found any other place that collects DEC stuff I don't know :) Replies to email address he's given me (suttonmr(a)navair.navy.mil), particularly as I don't know what the DRMO is! Pity there won't be any disks in that haul 'cos I could really do with some RZ29Bs....oh well. 'Course, it might also just be PCs. ------ realname: CECIL FINLEY email: ccfinley(a)bellsouth.net message: I'm a contractor for the US gov't and they are in the process of getting rid of a load of DEC equipement. You could get these items through the DRMO, but you'd have to pick them up and ship them personally.
