WAS: SCSI CD drive capable ... IS: drivers for Phillips Changers

The drivers my division sold were all for Microsoft Windows. And they were contracted out to Roxio or Nero. In fact, I don't remember seeing any drivers for the "jukebox" chasses except for the inhouse test systems. Billy

I'll program your example using the gpib library for Linux and then experiment from there. Regards, Dave __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

new HP-2100 collector

by Tim＠rikers.org

Seems I just took the plunge. I found a stash of hardware here and saved it from the great bit bucket in the sky. Inventory: * HP-2116A - broken chassis, missing glass panel * HP-2100A - missing cover * HP 21MX 2112A * HP 21MX 2108A * HP 12979A I/O extender * HP 2761A optical mark reader (melted rubber wheel) * HP 2748B tape reader * hp unknown mag tape drive * 7901A disc drive that's been dropped * 2 * HP-7900A disc drives * 2 * 13215A disc power supply * Commercial Controls Corporation tape punch * unknown data logger and other misc cruft. I've not tried turning any of it on yet. Many thanx to Jay West who identified much of this stuff over the net and walked me trough tieing the heads on the drives for the move. The HP-2116A was literally on the curb on it's way to the scrap heap. Parts had been scavenged, etc. I think I got all the pieces that there were to get. No power cord, etc. what kind of power does a 2116 need? If you've read this far and can stop drooling on your keyboard, I put pictures up. Some of the pictures are other stuff that was there, that the would not let me grab. http://rikers.org/gallery/hardware Does anyone know what the "Sandia Laboratories" desk + racks is for? There is only one thing left in the rack and it's in real bad shape. http://rikers.org/gallery/hardware/20050415_092748 http://rikers.org/gallery/hardware/20050415_092802 http://rikers.org/gallery/hardware/20050415_104726 -- Tim Riker - http://rikers.org/ - TimR at Debian.org Embedded Linux Technologist BZFlag maintainer - http://BZFlag.org/ - for fun!

IN MEMORIAN: Alf Jacob Munthe of Minnesund, Norway

by waltje＠pdp11.nl

Hi, It is with great sadness that I report the death of fellow collector of old computer systems Alf Jacob Munthe, of the little town of Minnesund in Norway. Although it was expected, it still came too soon. The fatal desease he was fighting would win eventually, and it did. I hope he now enjoys endless being without the pain that kept torturing him. Alf Jacob contacted me last year, after a posting from Dave Dunfield on this list, regarding taking care of his babies, that being a set of mint-condition IMSAI systems. This did require several months of co-ordinating, but they are finally on their way to my place, where they will kept in the same way he cared for them. I wish his wife all the strength in dealing with his passing. Let this not start another discussion on wills and such.. just make sure you got that covered BEFORE it's needed. With kindest regards, Fred -- Fred N. van Kempen, DEC (Digital Equipment Corporation) Collector/Archivist Visit the VAXlab Project at http://VAXlab.pdp11.nl/ Visit the Archives at http://www.pdp11.nl/ Email: waltje at pdp11.nl BUSSUM, THE NETHERLANDS / Mountain View, CA, USA

NEC "Advanced Personal Computer"? & Secure data removal

by marvin＠rain.org

My understanding is that one of the specifications for removing secure information from a hard disk requires writing zeros to the disk six or seven times. Norton Utilities (old version) had diskwipe and filewipe where you could specify how many times to write to the disk. Some time ago, there was a discussion of how to recover data that had been overwritten. The only thought I have is that it would take some specialized equipment to read the disk and would take the hysterisis of writing to the disk into account. My guess is that the magnetic field would be such that after six or seven writes, the prior data would no longer be recoverable. > Which brings up another thought. how would one go about making sure > that data is securely wiped from a drive of a classic machine, without > physically destroying it? So it could be donated & reused? > > -- > --- Dave Woyciesjes

I've seen those cards but I can't remember what they are. <snip> OK I finally got the grey matter working and I remember what those cards are. They're DOS coprocessor cards. Yes, your HP can run MS-DOS. Somewhere I have some of the cards but I never found software for them. If you got a drive with your system, look at it carefully and see if it has the necessary SW. If you find the SW, I'd love to get a copy. Joe

I have put them on my FTP site ifctfvax.Harhan.ORG in the directory /pub/DEC/VXT2000. Beware, though, that one of the files is 10 MB and my FTP server does not currently support restart in the middle. (I want to implement it in my ftpd, but never get the time to do it...) MS

There are issues of mold attacking but I don't think this is the common failure that looks like fern leaves. I would suspect that one can protect a CRT that one expected might have troubles by carefully sealing the edges of the front shield with RTV. One might consider a repair by placing the CRT in a vacuum chamber such that their was some of that windshield repair fluid in a small dam around the edge. One would pump it out for at least one day and then while under the vacuum pour the repair stuff around it. Then release the vacuum and allow the repair stuff to be pulled into the glass. Not an easy process but it might work. Dwight

But on the plus side I now have a good reason to look out for other HP systems that *will* work with this unit. That's what I like about this hobby. It's so self-perpetuating.

OT??? I dont know

by jim.isbell＠gmail.com

I dont know if this is off topic or not. Seems like every time I post to this list I am chastised for OT. To me any computer over 5 years old is an antique. But I would accept the definiton that any computer that used dual triodes was an antique, like the IBM 7070 that I cut my teeth on. BUT....be that as it may, I have several old computers that I am considering disposing of, but before I do I am wondering if they are "classics" Case in point: Nixdorf LK 3000 Electronic Notebook -- Jim Isbell "If you are not living on the edge, well then, you are just taking up too much space."
