OT: mechanical computer monitor

by dpeschel＠eskimo.com

We already had the "mechanical fax machine" thread... here's a (partly) mechanical computer monitor. It uses classic technology (the Nipkov, or I think also Nipkow, disk) but it shows a computer-generated digital signal rather than an analog signal. So it's computer-related! :) http://www.media.mit.edu/~rehmi/rotoscope/ The creator wants to make a "wind-up browser" in the same way you can get wind-up radios and flashlights. -- Derek

Tandy 1000 EX free to good home

by Glenatacme＠aol.com

This unit looks okay but is untested. If anyone has any interest I'll fire it up. You can have it for the cost of shipping. It came with a monitor (probably mono or CGA), but I doubt anyone wants to pay the freight on it. Let me know. Glen 0/0

Anyone interested in VAX tapes

by mcguire＠neurotica.com

I'd suggest either giving them away (post a "who wants these" sort of message here, for example) or putting them up on eBay. Throwing things in the trash, especially things which...well, aren't trash, is never a good solution. -Dave McGuire On June 14, Mark Champion wrote: > I have 30 small (6" dia) VAX tapes (Opus 6250) and 12 large (7" dia) VAX tapes (Scotch 700). > > I believe the small tapes are 600' x 1/2" and the large tapes are 700' x 1/2". > > I think they have all been written on once. > > Are these worth anything to anyone? > > What should I do with them?

New find: HP 1000 E series

by cem14＠cornell.edu

Well, today I walked by the auto labs in mech engr and found that they had finally finished dismantling this very old combustion/emissions test rig, and the HP1000 computer that ran the whole show had not been hauled away yet. Somebody had laid a claim on it two weeks ago, but since it's so long already and they haven't showed up, the person who handled the decomissioning gave it to me. I have not been able to open the front panel latch because I do not have the key, so I don't know what's in the front card cage; all I know is that there are seven cards, four at the botton and three at the top. In the back cage there are three jumper cards, two 12821A disk interfaces,one "time base generator card", and four cards marked "BACI 12966A" where most of the control I/O was apparently done. There are two big cards below the main card cage, but I haven't got to them yet. I also got several cables; two of them obviously connected the disk interface cards to an HPIB device (an HP 7946 tape drive also came in the lot), while others went to the test rig, and yet another seemed to go to a PC being used as a terminal. Unfortunately, I don't know where the cables were originally connected, as somebody had already pulled all cables off the computer. The machine is very, very dirty; not surprising considering where it came from (a car shop). The fans are full of oil-impregnated dust. I don't plan to power it up until I know more about it. They tell me that it was still functional about three years ago. Apparently nobody has touched it since. So, does anybody have any info on the power supply of this thing so I can test it before applying power to the cards? And, where did the console go in this machine? Best regards, carlos.

Pickin's are so slim out here, last time I picked up anything interesting was right about early March or so. My point is simply this: If there is anything I have learned in this long, strange trip that is life, it is to never complain about anything, there is always someone who has it worse than you do. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Lexmark Lexbook MB10 power suppply question

by ss＠allegro.com

Hi, I recently found a Lexmark "Lexbook MB10" ... with no docs, no power supply. The back of the computer says the power supply should be 12 V DC, but has no mention of the polarity! Does anyone have this oddball computer, and can they tell me the polarity of the adapter, please? BTW, this Lexbook looks like IBM's answer to the HP Omnibook 425. In web searching, I found several references to other Lexbook models (including the SE10), but none to the MB10. Lexmark's web site was an example of corporate stonewalling (not quite the word I want): since it's obsolete, they have no information on it, and don't even admit (via their search engine) that it might have once existed! Altavista found a single Lexmark.com web page about "Y2K compliance" ...which basically says: hey, it's obsolete, we didn't test it, buy something newer. thanks, Stan Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler

OT Vast amounts of NASA data in weird formats (Long)

by mmcfadden＠cmh.edu

Now that the subject line somewhat matches the topic. NASA and other unnamed government agencies collect "LOTS" of data. They have lots of tapes, some ASCII card images on tape, and other raw formats. Now when a project is winding down do you think anyone "cares"/spends money to transfer any data into newer formats. The original software that was written probably handles the data and works OK. I understand that lots of LANDSAT data has cloud cover obscuring it. Do you save even the "apparently" worthless stuff? The first thing any engineer/programmer tries is to pack the data onto the tape as efficiently as possible. 12 bit pixels get stored 2 pixels in every 3 bytes. Everybody used different methods to handle uneven numbers of pixels, including padding, and truncation. How do you decide how the data was stored. I'm sure the paper that documents the data format is detached from the physical tape. The short answer is that when data is collected no one has any idea of what eventually may be done with the data. They only expend as much time, energy, and money as the initial project seems to justify. I will try and find my copy of a GAO report that I purchased on the magnitude of the data storage/retention problem. They had pictures of doors in the data vault being held open by stacks of tapes. Mike mmcfadden(a)cmh.edu Data Hound extraordinary, I'm burying my floppy disks for posterity. Maybe we should use gold floppy disks will not oxidize and absorb moisture in any short term interval.

Though I must point out that it has nothing at all to do with "older" or "newer" systems...it's primarily a "windows" or "non-windows" issue. -Dave McGuire
