Hi folks, I just read your responses to my TU56 lamp question. That brought the "lamp discussion" back to onto my mind. I have some information to share, perhaps it might help: I recently got a box of original lamps from a retired DEC service engineer. The blue ones (blue seemed to be VERY important as someone also wrote the word "blue" onto the box!). The box is labelled "Oshino Sub-miniature Lamp". Made by Oshino Electric Lamps Works, Ltd, Shinagawa, Tokyo, Japan. The box calls the lamps "OL-2, 10V, 40mA". The part number is 12-09129. The "OL-2" is stamped onto the box along with the ratings. The part number is written by hand - together with the "blue". The lamps carry the part number. (I have another box with lamps for RK05 etc. They have the part number on the box and "OL-1" directly on the lamps.) Now I used google - and Oshino is still around! I found their German website with some part lists. All article numbers start with "OL-". The T1 3/4 sized bi-pin lamp that takes 40mA at 10V is now called "OL-367BP". Perhaps it's just the same. The light output is told to be 0.08 MSCd. The company's logo is the same as on my box and the CEO's name is Takeshi Oshino. So there is a good chance to get the original lamps. I have not yet checked if the lamps I got were the same I find in my machines, but the brightness perfectly matches and they come from DEC. Stored together with little boxes containing new DEC labelled ICs and transistors. That should vouch for them. Best wishes, Philipp :-)

Trouble installing system on a Macintosh Quadra 660AV

by thrashbarg＠kaput.homeunix.org

Hi, I've got a Mac Quadra 660AV which refuses to install any system software, except System 7.1, which it refuses to boot from (apparently it needs a newer version, but web pages about the Mac say it should work). I've tried System 7.1, 7.5 through 7.5.3, and Mac OS 7.6. It happens right at the end of the install, when the system is being finalised. I've replaced the battery, cleared the NVRAM, updated the disk driver and set the date. I'm using the original hard drive. Does anyone have any ideas? Alexis.

Request for computer displays at 2010 Midwest Gaming Classic

by wgungfu＠gmail.com

Heya all, doing the annual display request for the museum hall of the Midwest Gaming Classic. Looking for people from the list who specialize in classic computers to run a display area for their computer of choice at the show. I cover the bulk of of the pre-'84 consoles and computers, so it's harder for me to set up as dedicated a display as somone who specializes. The MGC is an all encompasing electronic entertainment show (consoles, computers and coin-ops from past to present). We hit around 4000 people this past year's show, and are expecting even more growth with the move closer in to Milwaukee this year (we're at about 30,000 sq. ft now as well). Besides the retro crowd, most of our actual attendance are the casual and family gamers of all ages, so it's a chance to expose this great hobby to a newer generation. Currently we have people coming to support their own Commodore and TI areas. Here's photos from the show this past March to give everyone a feel for the show: Museum area http://www.flickr.com/photos/91071283 at N00/sets/72157615834963880/ Underdog Chamber (also in the museum hall) http://www.flickr.com/photos/91071283 at N00/sets/72157615746538685/ Family Game Room (also in the museum hall) http://www.flickr.com/photos/91071283 at N00/sets/72157615835258766/ Competition Area http://www.flickr.com/photos/91071283 at N00/sets/72157615745281965/ Coin-ops http://www.flickr.com/photos/91071283 at N00/sets/72157615745260231/ Vendling hall http://www.flickr.com/photos/91071283 at N00/sets/72157615745200729/ It's Saturday, March 27, 2010 from 10:00am to 8:00pm and Sunday, March 28, 2010 from 10:00am to 5:00pm, at the at the Brookfield Sheraton, just outside Milwaukee, Wisconsin. Please contact me if you're interested in helping out, or midwestgamingclassic.com if you're interested in the show in general. Thanks! Marty

Picked up some new toys today...

by brianlanning＠gmail.com

I actually got some good deals from ebay today. One was an amiga 1200. It included a 68030-50 accelerator board (with scsi controller), 3 external scsi-2 hard drives, an external nec scsi cdrom drive, a 3com pcmcia network adapter, a commodore 1902 monitor, and about 300 floppy disks. (I will never run out of floppy disks again, lol) That was $250. I also bought a power computing ppc604e mac clone with a 17" (i think) apple monitor, several keyboards, and a mouse. That one was $20. :-) He also mentioned another computer that he'll be pulling out shortly. He claims it's an ibm 5150 or 5160 with original cga monitor and... a 386 upgrade board. Not sure what's up with that, or even if he'll want a reasonable price for it. I guess we'll see what happens with that. brian

Anyone near Grove City, PA?

by curt＠atarimuseum.com

Hi, Anyone near Grove City, PA ??? I have a solder rework station out there that needs to be picked up, its about 100lbs or so and I don't want to chance it being shipped. I'm willing to meet off of Route 84 to anyone willing to pick it up and make the trip part (or most) of the way to Carmel, NY (its about a 5+ drive each way and I'm not allowed to drive more then 2 hrs right now because of the heart surgeries I had.) I'm willing to pay anyone for the pickup and delivery, let me know off-list, thank you. Curt

TU56 lamp replacement

by djg＠pdp8online.com

> I also found this: http://www.pdp8.net/tu56/tu56.shtml > in which Dave G. describes a successful use of the CM2182 (14V, > 80ma) bulb in this application. > I just replaced one of them again last week so I had taken a picture of the indicator disassembled. It is now up at http://www.pdp8online.com/tu56/pics/p1000839.shtml?small If your TU56 -15V input is high you may run this bulb above their rated voltage shortening their life.

Sinclair ZX80 on Ebay

by julianskidmore＠yahoo.com

Hi folks, > Well I was. Was the difference the fact video stopped when the cpu > was not in the idle key press loop? There's quite a few differences between the ZX80 & ZX81. The ZX81 supported 'compute and display' thanks to its more 'advanced' video chip! The ZX81 was (AFAIK) the first use of a gate-array chip in a home computer! The ZX81 had an 8K ROM with floating point arithmetic, 'graphics'; decent string-handling and ZX printer support! The ZX81 syntax-checker was nicer. The ZX81 had a heat-sink that worked! The ZX81 was unbelievably slow! The ZX80 had that certain 'je ne sais quoi' that makes it at least worth 10x more than any ZX81. I'm convinced about this, being the lucky owner of one* ;-) -cheers from Julz @P * It was given to me as well, for which I'm really thankful!

Athena Computer

by evan＠snarc.net

There was a company called "Athena Computer and Electronic Systems" based in San Juan Capistrano, California in the early 1980s. The president was David Mitchell. Anyone know where I can find him today? Or does anyone know of other people who worked there?

Data General Eclipse MV/9000U available in Hayward, California

by sellam＠vintagetech.com

There is a Data General Eclipse MV/9000-U CPU (and cabinet/power supply if you want that) available in Hayward, California. Further model information is "G11202-G7". I don't know much about this. Photos here: http://siconic.com/crap/hayward/ Someone apparently dropped it since I last saw it. Don't know what damage has occured, but at least the photos give you a general idea of the size. My guess is if you want this you'll just want the CPU. It's in there...somewhere. Contact me directly if interested. -- 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 ]
