Another original Apple I sells for an insane amount

by tothwolf＠concentric.net

Vintage Apple-1 Sells for Record $671,400 http://bits.blogs.nytimes.com/2013/05/25/vintage-apple-1-sells-for-record-6… Whoever bought the thing from Mr. Hatfield earlier this year really should be ashamed of himself. I for one hope someone out there could at least send Mr. Hatfield one of the Apple I replicas.

The TFDOS as it is called, will be next. As it has everything; enough RAM, disk controller, serial port, there should be no reason why it should not work. I might try it, maybe even before retirement ;-). With the information in "The Programmer's CP/M Handbook" it should be no problem. > > -tony > Fred Jan

HP C8000 HP-UX

by mnusa2＠hotmail.com

Hello to all HP-UX fans. I got one HP C8000 but my 2003 HP-UX 11i.v1 CD fails to install. Can anybody inform me where to get the proper version? HP workstations are licensed to run HP-UX so that should not be an issue as far as I know. Download of image would be all that is needed.

9895A motor belt?

by cruff＠ruffspot.net

I have just got around to testing my 9895A with two drives. One drive works fine, the second fails to spin the floppy when the heads load. My guess is that the belt is stretched, and I don't yet know if there is sufficient adjustment available to take up the slack. Does anyone know the specs of these belts and where one might obtain a replacement? A search on the HP part number does not turn up much.

Spec of Motorola 7339 Transistor

by robert.jarratt＠ntlworld.com

I am trying to find out some information about this transistor from my ASR33 Teletype. Ideally a datasheet to tell me what kind of transistor it is, and even better any information on whether it has a modern equivalent. This page: http://www.diyaudio.com/forums/parts/167680-vintage-transistors-6.html suggests it might be a 2N176, but I am not sure. Anyone have any information, old datasheets or anything else that may help? Thanks Rob

HP-85A/B display and power supply schematics?

by cruff＠ruffspot.net

Has anyone managed to create schematics for the display and power supply for the HP-85A/B? I don't know yet if Tony's schematics for the 87 are applicable or possibly close enough for these boards. I have both an 85A and 85B with identical display issues, which I expect are due to old capacitors causing poor voltage regulation and/or ripple. The pincushion test looks pretty good, except for a bit of vertical displacement (think low amplitude waves) on the horizontal lines. The second issue is when a lot of white is being displayed (i.e. reverse video), there is a distinct narrowing in the scan line width in the top inch or so, with the narrowest at the first scan line. Then there is a gradual widening towards the bottom, with the lowest scan lines ending up off the sides of the phosphor.

Timex TS1000 for shipping

by doc＠vaxen.net

Hi, I'm doing a bunch of spring cleaning and will be offering stuff up as I go. Free & cheap will get pimped on ClassicCmp. Some of the things I think are valuable will go straight to Ebay. Anyhow, I have a TS1000 and a bunch of program cassettes, but no way to test them. The doorstop itself ran the last time I plugged it in. I'd say less than $10 shipping in the lower 48 from Austin Texas. Of course if you come get it, you go to the head of the class. Doc Shipley

OT: rubber drive belts

by jules.richardson99＠gmail.com

I seem to collect more bits of vintage hi-fi equipment than I do computers these days (they're much easier to find around here)... Anyway, I've got an early-'70s receiver with a built-in 8-track deck where its drive belt has turned to black goo in the same way that QIC drive pinch rollers often seem to do (and oh how that stuff gets everywhere). Exact part replacements by manufacturer / model are unsurprisingly unavailable - but I expect that the belt material is the same composition as that used for e.g. floppy drive spindle belts (or at the very least, floppy drive belt material would work nicely). So... I could measure the pulley diameters and spacing, but does anyone know of somewhere that sells such belts by length/width rather than "this is a belt for xyz"? (and, if such a place even exists, do I need to correct for belt stretch, or is that factored into the sizing already?) cheers Jules
