At University (UT-Arlington) we had scores of former IBM 026 keypunches from MAI that were refreshed, painted blue (from IBM 026 battleship grey), and (I think) refitted with 029 character set.

More vintage hardware still alive and kickin'

by aliensrcooluk＠yahoo.co.uk

Pretty cool video. It's just a shame there weren't any closeups of the punched cards. I'm just curious... how many cards would a machine like that sort through in a day, or a week? That counter has 6 digits and it sorted ~90 cards in less than 10 seconds.

wire wrap machine pins

by lynchaj＠yahoo.com

Does anyone know where to get those rows of individual machine pins for > wire wrapping? [snip] > > Andrew Lynch > Hi It seems I just saw those in the Jameco catalog. Dwight -----REPLY----- Thanks Dwight and Chuck! I found what I was looking for (wire wrap SIP sockets) in the Jameco catalog for a fairly reasonable price. They also have terminal pins but not the machine pin variety. Digikey has those, as Chuck pointed out, but the price seems unreasonable. $35 for a small bag of socket pin terminals? Wow! Thanks and have a nice day! Andrew Lynch

Inappropriate remarks (Was Fwd: Mystery object... )

Warren -----------Reply: Well, the original "humorous" comments didn't bother me much, but I did find it puzzling and disturbing to subsequently read that unless we ourselves had lost someone it is *offensive* and we have no business asking for a little consideration for those who did, that while the twin tower and Katrina victims (Americans, incidentally) deserve our respect the 200+ folks lost on the way >from Brazil to France apparently don't, and that since everybody dies one day anyway what's the fuss about. That does seem to demonstrate a lack of empathy, which is generally considered as a possible mental aberration, so I was just looking for a plausible explanation that would allow *me* to empathize with the folks expressing the above views, assuming they weren't just trolling. If the folks in question really did suffer from head injuries, then they do have my sympathy and I apologize. A fascinating and disturbing glimpse into different perspectives... m

N8VEM S-100 prototyping board PCBs available!

by lynchaj＠yahoo.com

Hi! The N8VEM S-100 prototyping board PCBs are available. I tested one out and it seems to work fine. It fits in the S-100 connector on the N8VEM S-100 backplane just right and the pads line up with the pins as you would expect. I assembled the components and the proper voltages appear in the correct places. They seem really nice and I am very happy with how these turned out. Pads for +5V, +12V, and -12V regulators with filter capacitors are on the PCBs. You can optionally install them or change them around as you see fit. The PCBs are $25 each plus $2 shipping in the US and $5 shipping overseas. Please contact me off list if interested in some. I posted some photos in the N8VEM wiki S100 folder if you would like to see them. http://n8vem-sbc.pbworks.com/browse/#view=ViewFolder&param=S100 I am really looking forward to building some S-100 home brew computer stuff with these boards. This is going to be a lot of fun! Thanks and have a nice day! Andrew Lynch

So, do you guys go around to funerals in your spare time wearing funny hats and telling the bereaved mother that her son's untimely death is insignificant compared to the starving kids in Africa, and besides, he would have died some day anyway? And when someone suggests that's a bit inappropriate you deck 'em? Inability to empathize is often the result of a brain injury; had any bad bumps on the head lately? m

by ragooman＠comcast.net

Another successful launch from Vandenberg AFB. Vintage hardware is still alive and kickin' ! My buddy there tells me the contract for the TIPS facility has been renewed at USAF Western Missile & Space center With many more launches to come. http://www.defense-aerospace.com/article-view/release/105054/delta-ii-launc… "TIPS consists of two systems of the CDC Cyber 840 computers, 21 systems of the SEL 32/55 and 32/75A computers, and various peripheral and supporting equipment on 2 acres of floor space." http://www2.applegate.org/~ragooman/computers_mini_gallery_tips.html I wonder what other vintage hardware is still in operation -- museum collections don't count :) =Dan -- [ = http://www2.applegate.org/~ragooman/ ]

QIC cartridge tape compatibility

by ian_primus＠yahoo.com

I have an older UNIX system with an internal Archive Viper 150mb SCSI QIC tape drive. In the drive was a DC600A tape cartridge. What's the difference between DC600A cartridges and the DC6150 cartridges I remember seeing years ago? I've tried reading this tape, but it doesn't appear to contain readable data - but then again, it may not have ever been intended for this drive. -Ian

Repairing an HP3421A (Signature Analysis)

by vp＠drexel.edu

I am trying to repair an HP3421A data acquisition and control unit that fails its power on tests. In the service manual it refers to a number of "Signature Analysis" tests that essentially mean that the unit runs some diagnostic routine and you go and collect "signatures" from various test points. Unfortunately I do not have a device to compute these signatures. Does anybody know how to calculate them using a logic analyzer (I have a Bitscope and an HP 1630D), or something similar? Thanks **vp
