Hi all, I'm looking for a KW11-L line time clock (that's the M787) for a PDP-11. I don't suppose anyone happens to have one lying around they'd be willing to part with for a reasonable sum or maybe trade for other DEC stuff? A KE11-F floating point module (M7239) would also be a welcome addition, although I suspect there's much less chance anyone has one of those going spare ;-) Cheers, -- Steve Maddison http://www.cosam.org/

MIT based on rip off NES and not Apple II

I have the manual (with a 5036A) and am willing to loan it out, but not if the spine must be cut. -Dave -- Dave McGuire Port Charlotte, FL

If there's anyone in West Yorkshire with a working BBC Master and disc drive,

by listmailgoeshere＠gmail.com

please could you get in touch? I've a disk I need to read, and I've just discovered that my Master no longer feels like working :( ObCCTalk: symptoms are just the message "Acorn MOS, Acorn ADFS" and then a flashing cursor upon switch-on. The drive does click as if it's being selected, and the light comes on, but there are never any head-movement sounds, and nothing further happens onscreen. Thanks, Ed.

RetroGraphics VT-100 or not?

by legalize＠xmission.com

Can someone confirm or deny that the following two photos: <http://www.xmission.com/~legalize/tmp/1.jpg> <http://www.xmission.com/~legalize/tmp/2.jpg> depict a retrographics upgraded VT-100? This seller previously sold a number of retrographics VT-100s on ebay that were badged as such, but this one lacks the retrographics badge on the exterior of the case. I can't tell from looking at these pictures of the insides if its got the retrographics upgrade or not. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Double-Sided disk drives reading Single-Sided disks (HP 9122 vs 9121)

I'm fairly confident the 1630G won't care [...] Unfortunately, the HP9121 and HP9122 are very different. The former uses the Amigo protocol to communicate with the host while the HP9122 uses the more recent SS-80 protocol. If the 1630G can use both protocols you are OK, otherwise you're stuck. The HP-85 had an optional ROM that allowed use of SS-80 drives, perhaps there is a firmware update for the 1630G that talks SS-80. Regards **vp

IBM Powerstation 320h

by slawmaster＠gmail.com

A friend of mine told me he just got an IBM Powerstation 320h system and wants to know if I want it, but I can't seem to find any information on it. Anybody here got some typical specs and/or opinions on the computer? Thanks John -- Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn

9 track tape drive motors - suitable for a go-kart?

by sellam＠vintagetech.com

Brad, I suggest a much better use: turn it into a windmill. I finally got my hands on a motor from a 9-track I scrapped. It puts out several amps at 24V+ when I hand-spin it. It will do nicely as a current source to charge a lead-acid battery, especially where I live: http://en.wikipedia.org/wiki/Altamont_Pass_Wind_Farm As Tony already mentioned, it won't have enough power output to be good for a go-kart. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

9 track tape drive motors - suitable for a go-kart?

by brad＠heeltoe.com

This has only a little to do with classic computing, but it seems like it could generate epic amounts of email, so what the heck... Does anything know much about the construction and capacity of a typical 9 track tape drive motor? Like the big 1 foot x 6" tubes which I've seen a kennedy or DEC drive? I don't know anything about how they are constructed, but I assume they are high RPM and high torque. And probably some sort of DC stepper. I have a racing go-kart frame which is currently missing a motor (a CRG if anyone cares). It occurred to me that it might be fun to grab a large number of high capacity batteries and somehow rig one of the tape drive motors to the live axle. I assume via a reduction gear and chain. (clearly math needs to be done, but I want to start by finding the right motor) I would imagine several versions, starting with the simplest version but moving to something where both rear wheels are driven and having some sort of "software differential" and the moral equivalent of compression braking. no doubt there is something like alt.cars.electric-karts where I should go with this, but I thought i'd ask about the tape drive motors first. Anyone know what their specs are approximately and if they would be appropriate? (my goal is to be able to smoke the rear wheels and then turn on the traction control :-) clearly I've been spending too much time on the Tesla and Spacex web sites :-) -brad
