Hi, I wonder if a ST506 drive can be used without problems on a SA1000 interface controller. The signals seems to be the same, but ST506 is working on a slightly higher transfer rate. Would it work with a 50 -> 34 pin adapter cable? Did even someone has experience in it? Seems hard to find SA1000 disk drives nowadays... -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/

What is this system?

by roger.holmes＠microspot.co.uk

Now I have more space in my computer room my elder brother offered me two systems he picked up some years ago. I don't know much about either, but bitsavers has references to one, which is a Texas Instruments 990 with twin 8 inch floppies and a terminal. I have not tried powering it up yet and I dont have any boot disks but it looks interesting. It has a 12 or 13 slot chassis with most of the standard cards present except no printer card. Is this rare, can I get boot disks, would anyone want to buy it, what can I do with it? Much the same questions for the second system but also, what is it. It too has two 8 inch floppy drives, two volumes of manuals for Xenix but no floppies. It is marked "Advanced Micro Computers Inc Microprocessor Development System 29/05". There is a sticker saying Memec Systems Ltd. The front panel is divided into two, one says "Support processor" and the other "Microprogrammed system". Could this really be a proper microprogrammable system or is it just system using a microprocessor. Either way, which programming/microprogramming architecture is it? Any relation to the AMD 2900 bit slice chips? For a couple of months I wrote microcode back in about 1974 but not on this system.

Microvax II chassis for trade

NorPak???

by Reid.Allen＠eni.com

Norpak was a logic device that used only 'NOR' gates. It preceded the PLC concept. The gates were hardwired. Since any logic function can be created using negative Boolean operators (NOR or NAND) they were usable for solid state control systems in place of relays. We used a Norpak system at the San Francisco International Airport on a plane fueling system in the middle 1960s. They had 10 NOR gates per module, and we wired modules using something like #20 AWG wires with some kind of termination on the end that could be inserted into the Norpak units. One had to be very careful using the units because after the various functions and their arrangement had been designed there were often redundant gates in series that could be eliminated, but this caused transparency of design to be lost. I was working for the Standard Oil Company of California in those days down on 225 Bush Street. Reid C. Allen, P.E.

govliquidation.com raises minimum bid from $50 to $150

Has anyone else noticed this? For all the items in Utah being auctioned, the minimum bid is now $150. That moves most of the stuff out of the bargain category, IMO. $150 for a 20 year old oscilloscope in unknown condition with no probes or manuals?

COBOL Poster

by silent700＠gmail.com

I've finally gotten around to photographing a poster I've had for a number of years. Hoping it triggers some memories for at least one person here. I'd love to know who made it, when and most of all *why*: http://flickr.com/photos/chiclassiccomp/3037313448/in/photostream/ It's fairly large, maybe 3'x5'. It's actually textured - all the white areas are printed with some sort of coarse sand or grit. Right above the lower brown bar is written in pencil "A New Language" and signed, as far as I can tell "D. Meeny." Googling this info has turned up nothing for me. This was some serious work. I'm not one to question an artist's muse - but someone, somewhere, at some time, sure loved them some COBOL.

Offer: VGA Video card "collection"

by wpileggi＠juno.com

It's the end of my fall clean-up, and I've decided to discontinue "collecting" VGA video cards any more; though the proper term might be "accumulate"... I did find it fascinating to note these were state-of-the-art in their (brief) day, we spent upwards of $300-400 on some of these and they are now boards I pull to scrap... Roughly 1990-1999, ISA, PCI and AGP. Been doing this for the last 10 years or so. I have a list of brands and models, please email me off-list request a copy. Anybody else 'collecting' VGA cards? I don't have a price, is there a market? I also have a list of Creative Labs Sound Blaster cards...Bill KA3AIS ____________________________________________________________ Planning for retirement?

Photos of the N8VEM ECB Bus Monitor

by lynchaj＠yahoo.com

Hi All, Attached is a link to some photos of the N8VEM ECB bus monitor I just built. http://groups.google.com/group/n8vem/msg/2fe8df76d05be1d5?hl=en The design is pretty general as a Z80 bus monitor and the original C'T Projekt article mentions you can build an adapter to convert the ECB interface directly into a Z80 40 pin DIP socket. Although I haven't made the adapter socket myself, it makes perfect sense to me since the ECB bus is essentially just buffered Z80 bus signals and the bus monitor should not notice the difference. If you have any questions, just let me know. I have several of the PCBs left if you'd like to build your own ECB bus monitor. The parts are fairly inexpensive items and the PCB is only $20 plus shipping. Clive and Rolf posted a bunch of videos of the ECB bus monitor in action so you can see those to if you'd like. They are on the N8VEM website and on Rolf's ECB pages. Thanks and have a nice day! Andrew Lynch

Wanted: some HP 9000/3xx bits

I've since powered up the machine and it appears to be working just fine. I believe I skipped over that in responding to a thread about LCD monitors and output from late 80's and early 90's workstation framebuffers, but the 380 displays just fine on a 20" Dell LCD monitor using a HD15 to 3-BNC cable off of eBay. The current color framebuffer offers 6 bit planes. I'm assuming that were I to load NetBSD on it, X would immediately fall over. My experience a few years ago was that dependencies on greater than 8-bit color had crept into much of the standard distributions...

That is the web site of my project and describes the computer I have kept. Two of us work on the project, Rod Brown being the other person, and he does the web design, but he has not enough web space for anywhere near the amount of data which needs to be published.
