A friend is looking for 6 computer racks. He is looking for ones with "high ventilation (mesh doors, etc) and locking is a requirement". Anyone got anything like this in the MA/RI/NH area (or possibly local enough that can ship (at an affordable rate) via freight) ? If you don't have 6 then let me know what you have, and I'll pass it along with your contact info. -- Curt

Anyone know of a 1970s-style dot matrix "computer photo" generator/converter?

by ethan.dicks＠usap.gov

Hi, All, I'm sure many of us remember the "computer photo" craze of the late 1970s - go to a mall, get your photo taken by a computer, then buy one of a number of trinkets (calendars, coffee mugs, etc.) with your photo rendered by dot matrix... an old family friend even had one of those rigs - driven by an Ohio Scientific Challenger III (a machine I've long lusted after). There must be a way to simulate that look today - some sort of GIMP filter or web app or something. I've been googling around for "ASCII art" and "dot matrix photo", etc., and have found some interesting stuff (http://blog.modernmechanix.com/2006/07/27/ascii-art-1939/) but not what I'm looking for. Ultimately, I just want to take a snapshot of me and filter it to resemble that 1970s "computer photo" look. Any suggestions where to turn? Discussions of how it was done and how it could be done with vintage hardware now are interesting and probably on-topic, but not the goal of my question.

Your suffering from PCism, you expect it to work like a PC and it will not. I'm using a 45MB fujitsu 3.5" scsi drive That was given to me and a modified version of the ampro scsi bios. The base SCSI software supports a limited number of drives and SCSI to MFM bridges that were available in the mid to late 80s. Those would be the Xebec and Adaptec and one seagate drive all in the 10-30mb size range. Add to that at the time the AmproLB+ software was written SCSI nee SASI was still somewhat developmental. Yes, I had to take the Ampro sources and rework them a bit for that drive and debug them. The basic code is online in one of the repository sites and it's well done so modifying it should be resonable. I'll admit it's been 17 years since I did it and it's running so I haven't looked at it in a long while. Hope that helps.

Vinyl Data- Classic Computers / Indie music tricks crossover

by tpeters＠mixcom.com

http://www.kempa.com/wp/2004/03/09/vinyl-data/ Excerpt: One strategy that major record companies have been employing lately to deter downloading is adding bonus computer content to new CD releases. I recently discovered that this technique is not unique to CD?s, but had in fact been practiced in the vinyl era as well. That?s right: there were a handful of records released in the late 70?s and early 80?s that contained computer programs as part of the audio. This is totally insane, and totally great. Most of these programs were written for the Sinclair Spectrum home computer series. The Sinclair Spectrum was a relatively cheap home computer system that used a television set as a monitor and loaded programs from tapes. It thrived in England in the early 80?s: ----- 240.

HP9836C colour alignment (grey scale tracking)

by ard＠p850ug1.demon.co.uk

I am working on an HP9836C, in particular the colour monitor part. The original problem looked to be slight misconvergence, with red fringes. But I think it wasn't really convergence problems at all. I've been looking at the video amplifier PCB (the one at the back of the CRT) which not suprisingly contaisn 3 identical video amplifiers along with a blanking amplifier and components to pass the correct voltages to the CRT electrodes. Anyway, there's a resistor in each of the amplifiers that according to the colour bands should be 12.4k. In the green channel it's close -- 12.7k. In the blue channel it's nearer 17k, and in the red it's open-circuit. And I think this could be messing up the HF response of the red amplifer, hence the fringes. The problem is that if I replace it, I'll have to set what HP call 'colour alignment' and what I grew up calling 'grey scale tracking'. I've read the offical HP procedure (if you're interested it's pages 134-138 of the pdf service manual on http://www.hpmuseum.net/), and there are at least 2 problems The first is that I don't have a suitable photometer. The second is that even though it claims I need this photometer for the gain adjustment, the cutoff adjustments are done to 'barely extiguish the raster' I've worked on enough monitors to know that that's not precise at all, so I am wonderign just how accurte the photometer _really_ needs to be. Has anyone ever done this setup and can offer any tips? -tony

Wanted: HP264x terminal to host/modem cable

by legalize＠xmission.com

Hi, I've got several HP 264x terminals. These terminals expose a card edge connector off the back of the terminal to which you attach an RS-232 serial cable. Before I go to the trouble of making one of these, I wondered if anyone had one to spare?

ps/2 floppy drive

by rtellason＠verizon.net

I have this drive sitting here, and no particular use for it. I'd started talking about it to a list member some time back, but that never went anywhere. A label on one side says "DFL413C04A" and "Alps Electric Co. Ltd.", the drive has no faceplace on the front, and on the rear is a single keyed edge connector and no separate power connector. Anybody want to take this off my hands?

VAX 4000-300 shuts down

by IanK＠vulcan.com

All, I'm wondering if someone can confirm my diagnosis for a problem with my VAX 4000-300. One day, after it had been running for the better part of a week, I found it unresponsive with only the AC light glowing. I suspected an overheat problem, but the overtemp light wasn't on. Nonetheless, I shut the machine down, left it for a while and came back. It started up again, booted into VMS and seemed fine. I let it run for a half-hour or so, then shut it down normally. That was two days ago. I just tried to power it up again to do some work, and the power-on tests fail about halfway through (but never in the same spot, so I don't think it's actually a power-on test failure). The machine goes to the same state each time: just the AC lamp glowing. I even have the fans on high (and that's noisy), but no go. I figure it's time to replace the power supply unit (or refurbish it, but replacements are still relatively cheap). Any other thoughts? Thanks -- Ian

I took that loose, scrubbed pins lightly with very fine sandpaper and isopropanol, sprayed on silicone oil (but I'd recommend a contact cleaner instead), and re-seated both ends of the cable. Resistance across the cable (measured from solder joint on the back side of the analog board to solder joint on the back side of the digital board) went down from 10's of Ohms to fractions of an Ohm, and the system turned reliable. The resistance measurement is a pretty easy one to make, with the system off. I'd recommend that, at least. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

Copying Computer Audio Tapes

by grant＠stockly.com

I'm trying to get some loose ends tied up, and that involves duplicating tape cassettes. I have a TC-WE635 "Stereo Cassette Deck". It says "DC Servo Controlled Motor" on the doors, so it must be good! : ) It has "Automatic Tape Selection", so I will have to trust that... It gives me a selection of: Dolby NR (OFF) (ON) (ON FILTER) and then a (B) and (C) Which settings do I want to use? It has stereo audio outputs on the back, of course, so I will also record the audio into a computer. However these days I don't want to put all of my trust into the computer... Grant
