Hi List, In addition to salvaging what I can from my flooded basement, I'm also taking the opportunity to unload a few things that I no longer use. I don't know if anyone has any use for these boards from an intellec 800 box, but I thought I'd ask. As far as I can tell, they all work fine. 16K x 8 RAM 1001125 Qty 4 Processor 1000340 Front Panel Control 1000343 Monitor Module 1000351 Floppy Disk Controller 1001036 and 1000467 I also have two big blue floppy disk enclosures, each containing two 8" floppies (and one big honkin' power supply). Shipping costs for the enclosures are likely prohibitive, but I'm willing to pull parts out if anyone needs anything. Any takers?? I'm located in Saskatoon, SK, Canada. Pat

Diablo 30 power

by aek＠bitsavers.org

I was under the impression these were RK03s. Now I understand they are indeed RK01s. -- DEC never sold Pertec drives, though lots of third parties did. They most often showed up as Plesey add-ons. What you probably have is some variant of the D4000. They came as fixed/removable, just removable, 2315 front-load or 5440 top-load packs. The 2315 flavor was compatible to RK05's, 5440's were 5mb. Just checked, I have the D4000 service manual scanned, but it isn't up on bitsavers. I'll see about getting that done.

Depending on how many drives it can Are you sure that what you have are RK03s? The reason I question it is that the power voltages you've given for your PSU are totally wrong for the Diablo Model 30.

I hope this information is helpful to someone. -tony My mistake. I was under the impression these were RK03s. Now I understand they are indeed RK01s. What is the density of an RK01 pack versus and RK03. I think the RK03s held 2.5Mb per pack? _______________________________________________ Join Excite! - http://www.excite.com The most personalized portal on the Web!

Removing conductive foam residue from IC pins?

by jcwren＠jcwren.com

I have a bunch of old ICs that were stored in conductive foam, and I wish to move them to plastic tubes. The foam has decayed to that state where it just crumbles when touched. Any recommendations for cleaning off this old foam? It can be scraped off, to some degree, with fingernails, but I risk bending the pins, and it's not all that thorough. Soaking them in alcohol is probably not a good idea. :) --jc

And there was an older DEC drive, I think it was the RK01, that was a rebadged Pertec. -- The RK01 was made by IOMEC (also sold by HP as 2870A) and was used in the RK8 (NOT the Omnibus RK8E) I have the drawings for the RK8, which will go up on bitsavers as soon as the RK8 manual arrives from NL.

New Figurematic Today

by jrkeys＠concentric.net

I picked up a Marchant figurematic model 8ADX today at an auction from a guy that got it with some other items in the lot that he purchased. It had a power cord with it but by the time we meet in the parking lot to do the deal he had lost it. Anyone know a source for a power cord for this machine? Thanks John

Problem using st.exe to push data off to tape

by fireflyst＠earthlink.net

I'm trying to use John Wilson's ST.EXE program for DOS to push data off to magtape on my Qualstar 1260S connected to an Adaptec 2902, but it stops with a media error on every tape I try. Here's what I have done: - Created a DOS boot disk with only the aspi8dos.sys driver loading - Defined my TAPE variable as SCSI5: The tape files and st.exe are stored on a fat16-formatted IDE drive. That is all that is on there, and the disk was freshly formatted. Here's what happens when various commands are issued: - st iput filename.ext 512 - tape goes back and forth then stops with a media error - st write - tape goes back and forth and then goes back to a dos prompt. I try to do 'st rew' after this, but then it does what looks like the 'write' operation - st weof - "on line" light blinks continuously. This doesn't always happen, sometimes it does the 'st write' behavior. So, thus far, I have no boot tapes. Can anyone help me out with this? Thanks Julian

I had a chance to look in the manuals on bitsavers today. The Model 30 Maintenance Manual (not the parts list), gives the pinout of the power connector. I'd forgotten one detail, there are 2 connections for each of the +15V and =15V lines, one for the high-current, noisy, stuff (like motors), one for the low currnet, sensitive, stuff like the read amplifier. You should use separate wires for each connection and only join them at the PSU output terminals. There's also a maximum length of power cable, something like 5'. I don't see why this would be a major problem in any sane system layout. Oh yes, these drives take up to 8A (!) on the +/-15V lines. The PSU manual _is_ on bitsavers, I think. It's the Model 29 manual in the samre directory. No, this is not obvious, I was just looking at various manuals. The DEC PSU is, I think, electrcially different, though. -tony ----------------------- The power supply I have for my two RK8s (RK03s) is made by Pertec and is called the model 9000. Depending on how many drives it can be a 9001, 9003, or 9004. It shows +5, +12, -26, +24. The 9004 adds -24v. I hope this information is helpful to someone.
