I have been on this list for a long time as a reader and wanted to give the list a heads up on this system before doing anything else in case somebody wants it and can pick it up. -- Cabinet 1: Quickware Engineering QED-95 CPU replacement 2- TU-58 tape drives Cabinet 2: BA11-KW RX02 floppies Cabinet 3: 2- RL02 disk drives 1-MDI 76-contains 1 Maxtor XT8760EM 760 Meg HD Cabinet 4: 2-RL02 disk drives 1-MDI 276-contains two Maxtor XT8760EM 760 Meg HDs I am asking US$3000.00 for the four cabinets. I can't guarantee anything but it was turned off working fine. The buyer would have the option of buying up to 18 RL02K-DC data carts for US$25 each Shipping is probably not an option they are about 300lbs + each I am located in Kelowna BC Canada about 3hrs north of Spokane Washington.. Preference would have to go to someone that could come and get it. Pictures are here http://photoshare.shaw.ca/view/32499942349-1432868285-94725/0 Rod Rdooley at shaw dot ca

Wanted: stand for NeXT monitor

we have one of the NeXT cube looking computer, a monitor and a NeXT laser printer. looking for an archive stash of advertising lit. and graphics we can use to build a display around this hardware.

OT: Looking for the Tek 465 of Logic Analysers

by seefriek＠gmail.com

Maybe only semi-OT. I'm working on a couple of classiccmp-ish projects (6303, 6309 and 68030) and I find the trusty old Tek 465 o-scope is no longer compensating for my lack of design skill (or I'm getting better at hiding bugs in my designs, depending how you look at it). I'm looking for a recommendation for a logic analyzer. Considering my very modest design constraints, I'm thinking: - Suitable for 50MHz designs (really more like <16MHz, but you never know) - 32 channels would be nice, ~128 probably perfect, less...you know...do what you gotta do... - No weird technologies in the design (all TTL/CMOS logic) - I'm willing to spend a few $$ to get decent kit, but need to spend closer to 465 money than TLA7012 money - Decent analytics, hopefully more than "here's your traces...good luck" - Ease of finding complete kit; nothing worse than dropping a dime on what looks like a good deal only to find you're missing the unobtanium cable, or the software disk that the vendor will be more than happy to provide you only under a cripplingly expensive support contract. A brief cruse of ePay didn't turn up much Tek/HP/Agilent older-generation kit that looked like it fit the budget, but I'm not entirely sure I know what I'm looking at. I know there's a general allergy to anything USB around here, and worse Windows-based USB software, but there is tons of USB-based stuff that looked like a possibility for those who are willing to hold their nose. So have the USB logic analyzers achieved Willem levels of usefulness (which one?), or is there a must-have Tek 465 moral equivalent I need to be looking for? KJ

Looking for the Tek 465 of Logic Analysers

I can second that. I recently bought a flock of them (for spares/parts for the first one I bought), because they were so cheap on eBay - several I got for $25 + shipping. Most of the ones I bought came without probes, etc, but I managed to round up a very complete set of stuff without spending too much money. Tek documentation is incredibly thorough, and easy to obtain; and they are very easy to work on (in terms of accessability, etc). Etc, etc, etc. The speeds/etc you are looking for are within their range. When filled with 4 16-channel data acquisition cards, you get 64 channels. They seem to have quite powerful triggering/etc capabilities, and they are easy to use/control. The only possible issue (for some people) is that the memories aren't large (although you can chain identical DACs together to get slightly longer memories). And I'll echo Tony's comments - ECL is pretty much de rigeur, and as for making your own probes, fuhgeddaboutit; the 1240's probe pods (there are two kinds, TTL-only, and 'pick a voltage') contain giant custom chips.

PDP-12 Restoration at the RICM

by michael.99.thompson＠gmail.com

The RICM is restoring a PDP-12. This system was manufactured in December of 1972, so it is very late in the life of the PDP-12. The Priority Interrupt and the Data Multiplexer are hardwired in two extra columns in the processor chassis. These options were in separate chassis in earlier models. It came with an Omnibus expansion chassis that connects to the Posibus from the PDP-12. The LP01, RK05, and PC04 controllers are in the Omnibus chassis. The VR14 and TU56 controllers are in the processor chassis. We got the LP01 too. The donor did a great job of preserving the machine, and has all of the original documentation and software. The processor and RK8-F prints are newer than what I can find on the Web, so I will scan them and send the PDFs to Bitsavers. Yesterday we reformed the caps in the power supply and powered it on for the first time in 24 years. It is going to need some debugging, but it does show some signs of life. The CRT in the VR14 -- Michael Thompson

Sorry if I haven't back to you...

by shadoooo＠gmail.com

Hello Paul, good luck for your surgery! I hope there's nothing too bad. As for the "business", I sent you more emails in the last months, unfortunately no answer at all... maybe I went direct to spam? :( Anyway, when you are back good, please let me know something. Thanks Andrea

Old HP test equipment power connectors...

by jules.richardson99＠gmail.com

... the style of AC power connector having three 1/8" diameter pins in parallel on 5/16" spacing, with the center pin offset by 1/16" from the outer two, and the rubber molding around the pins having rounded ends. Is there an official/common name for such a connector so that I can try and lay my hands on some more power cables? Fluke used it too (and Moseley, but I believe they were just HP by another name anyway). I've also seen the same pin size/layout on desktop calculators, albeit with more squarish ends to the rubber molding (in fact the single cable in my possession is a calculator one, which I modified to fit the rounded-end profile) (while I'm at it, is there a classiccmp-type list equivalent for old test gear?) cheers Jules

Testing floppy drives

by alexandre.tabajara＠gmail.com

Howdy guys, greetings (as always) from Brazil! :o) I'm in a repairing spree! Got 5 (!) CP-500 (Brazilian TRS-80/III clone) to repair. All of them with single/double sided floppy drives, and the whole nine yards. Since it is not pratical to test all these drives on CP500, is there a good software solution I can use on a PC for floppy drive testing? Something that makes repairing easier? Long time I don't get so many drives to repair/refurbish/align Thanks Alexandre --- Enviado do meu Apple IIGS (pq eu sou chique) Meu site: http://www.tabalabs.com.br Meu blog: http://tabajara-labs.blogspot.com

Hi All, I'm looking for an old (before 3/2000) copy of Veritas* Systems "Storage Replicator" for Windows or "Volume Replicator" for Solaris. This is for business purposes - so there's a "bounty" available :) Cheers, Lyle * Later sold to Symantec -- Bickley Consulting West Inc. http://bickleywest.com "Black holes are where God is dividing by zero"
