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

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

Altos Computers near Seattle WA

by michaelgreen42＠comcast.net

I just bought up a large lot of vintage stuff and found 3 Altos computers in the lot. Not exactly my cup of tea for collecting but I know someone out there will be interested in these They appear in good shape overall (no broken pieces or anything). I hate eBay so thought I would post these here. I would prefer local pickup but I'm happy to ship too (they aren't that big). I'm taking offers for one or all.

Computer collectors are no longer the dweebiest people in the world...

by James＠jdfogg.com

> > I find almost anything old to be interesting. Lately I've been looking > > at old vacuum tube intercoms (the kind with art deco cases). > > What make? I'll bet I have manuals for some of that stuff... I like Rauland and Bogen, the Bakelite years. I'm watching eBay to see what comes up. Lately I'm spending a lot of time in the barn with some new horses and goats. I don't want to run a PBX extension to the barn, but an intercom is appealing. A lightning strike on a PBX extension would ruin my day. A tube type intercom is more likely to survive, especially a wireless one (carrier current I think is what they called that wireless method using power lines). Also, an intercom would let me monitor audio in the barn to see if everyone is getting along well in my absence. My other choice is a pair of VoIP capable routers and an 802.11 wireless bridge in the barn. I'll use the routers in an OPX configuration to the PBX.

I don't know about vacuum cleaner belt collecting, but I've seen some examples of lovely old (and odd) vacuum cleaners. I find almost anything old to be interesting. Lately I've been looking at old vacuum tube intercoms (the kind with art deco cases).

PC Unix wanted

by tommytune123＠gmail.com

Does anyone have one of the PC SVR4 releases from the early '90s? I'm looking for a complete set of Interactive, Microport, or Esix (have I forgotten any?). Prefer complete docs, and would rather have tape install than floppy, but I'll go either way. I'm happy to pay something reasonable. -Tom

MIT want to make $12 Apple II clone

Eric Smith did say: > Another criticism of OLPC, which I don't think you're trying to make, > but that many others have, is that they failed to make a $100 laptop, > since the price is around $188. That's what I was getting at when I said he needed to get his act together, i.e. try to get it down to $100. But even at $188, it is still a spectacular little machine. -- 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 ]

I'm driving from LA to midwest - any systems to trade?

by tosteve＠yahoo.com

Hello, I will possibly be driving from Los Angeles to Las Vegas to Denver to Omaha to South Dakota (and back) in early September. If you're along the route, I'm interested in trading some of my old computer systems for others of similar vintage/value/scarcity/coolness/whatever. Browse my site http://oldcomputers.net/ to see if there's anything that catches your eye. Not everything is available, of course, but feel free to ask. Steven Stengel.

MIT want to make $12 Apple II clone

by sellam＠vintagetech.com

A few (worthless) comments: 1) I agree with Eric Smith for the most part. 2) This will FAIL. 3) As Eric said, it's a cool idea for us retro-dorks, but for real people they will wonder why someone bothered to hand them a cheezy video game console for $12 that they earned working for four cents an hour from 6am until midnight seven days a week for eight years. 4) The title of this thread is dumb, but at least it's lame. 5) If Nicolas Negroponte (brother of John Negroponte, war criminal) finally gets his act together and is actually able to produce the OLPC for $100 then it would render this $12 thing a dumb joke. The OLPC is a real computer. I've used one. It is made from the element Awesome (symbol Aw). This thing being described wouldn't even be 1/12 of an OLPC. 6) www.xgamestation.com -- 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 ]

7) Right said Fred: "There exist non-infringing copies of the Apple ][ firmware - Basis, Franklin, and Laser128?" - I had the same idea...use the Franklin 1000 ROMs because they are legal and I doubt there is anyone left from Franklin to go after you. 8) Chuck Guzis made the most sensible suggestion I've heard in this entire thread: "I'd humbly suggest that they simply market a keyboard and mouse that interfaces with a mobile phone. There should be more than enough compute power there--and you get connectivity as a side benefit." It's genius in its simplicity.

MicroVAX 4000-105 Fast Wide Differential option?

by binarydinosaurs＠gmail.com

Folks, Today I came across an oddity, a standard ds-47dbm-b9 VAX 4000-105A but seemingly featuring a third-party FWD/DSSI/SCSI option. Instead of the usual angled rear connector box containing 2 DSSI busses and a SCSI-1 connector the machine had a rectangular breakout box that featured from top to bottom FWD SCSI (68pin), blank, DSSI (single port), SCSI-1. The FWD port was connected to a Baydel RAIDER5 raid system and also had a differential terminator. I'm pretty sure that wasn't a DEC option in the UK, 2 DEC resellers I know agree so has anyone else heard of this? I wasn't allowed to shut the machine down so I couldn't check for manufacturers or part numbers..... VMS designator for the drive was DKW100 which further points at it being wide SCSI.... cheers! -- -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? www.binarydinosaurs.co.uk

Vintage sun stuff free for collection in south bay area.

by silvercreekvalley＠yahoo.com

Hi Sorry for the short notice on this... I have various vintage Sun items available for collection following a storage clear out. No charge for the items, but collector must take everything as I wont have time to split or arrange for multiple pickups. *Various parts for a Sun 3/80 including case, motherboard, possibly floppy drive, and more parts (can confirm). *Sun 3/60 fitted with colour framebuffer. *Sun 2/120 deskside unit. This is the deskside Sun 2 case with internal PSU and multibus card frame. The original multibus cards have been removed and I am unable to find them. There is no keyboard. *Sun monitor (mono) *Various other computer related parts including an old acoustic coupler modem and phone and a motherboard from an old Sun server (VME bus I think). All these items are untested and for parts only - that is you should assume nothing works. Now for the bad news .. unfortunately these items need to be collected by Friday 8th August ie. this week so would suit someone in the bay area (CA). Contact me off list if interested. Cheers Ian.

WTB: SGI drive sleds/brackets

by oldcpu2＠rogerwilco.org

Wanted to buy for a reasonable price + shipping: 3-1/2" drive sled for SGI Indigo2 5-1/4" drive sled for SGI Indigo2 (x3) 3-1/2" drive bracket for SGI Indy Anyone with some extras? Please contact me off-list. Last weekend I came across a(n) SGI Indigo2 and several Indys at the local university surplus store. Having no experience with SGI gear I couldn't resist and picked up the Indigo2 and (x2) Indys. The prices were quite reasonable, and now I know why! There are no drives inside. As a rule, all systems from this outlet are stripped of their drives before being put on sale. If only I'd known. This particular surplus store always binds the machines closed with nylon shipping straps to prevent people from delving inside and lifting little parts without paying for the machine. So I couldn't 'pop the lid' and check them out. And, you can't cut them open until you buy. What is the saying?..."What you don't know can't hurt you," or something like that? ;) My ignorance of SGI gear and the store's policy cost me on this one. Live and learn! Anyway, I now have an Indigo2 (pre-IMPACT! green case) with what I think is 256MB RAM, and 2 identical Indys with R4600/133 CPUs and mabye 128MB RAM, all without disks. I'll know more when I get a 13W3-to-VGA cable rigged up. Anyway, hoping to resurrect them with some flavor of BSD, or even IRIX 5.3 if I can find it. Thanks, Jared

HP 5036A microprocessor lab - searching for copy of "Practical Microprocessors"

by simon_coleby＠agilent.com

Hi Stuart, This is a long shot, but here goes... I have an HP5036A lab, but lack the book. Searching, I found this on a forum from way back in 2003: "Yes, I managed to get a manual, by watching auctions on eBay. In fact, I bought another HP 5036A plus manual and let the seller keep the hardware to save shipping costs from England to the US. The manual is softcover and would not be easy to copy without cutting the spine off, which would ruin its value. Don't give up, though. I know someone that has a manual that has been cut up and copied and I'm trying to get it so that I can make an Acrobat PDF file of it. Stuart Johnson" I don't suppose you ever got a .pdf copy scanned? Just interested. Cheers, Simon Coleby Customer Service Centre.
