I just received a HP 1611A Logic Analyzer with Option A65 (6502 uP) and I am looking for 1) documentation, and 2) how to make the cable from the pod to the uP socket. My internet search (Google) turned up - zilch. If anyone has the operations manual and/or the service manual or knows where they might exist online, I would appreciate you posting the address or emailing it to me. If someone has the manuals and would loan them for scanning, that would be helpful too. Ditto for the manuals for sale. I'm sure the cable from the pod to the uP socket is quite simple, but as I haven't seen one in 15+ years, could someone describe it for me? If someone has one for sale, that would be good too. I am also interested in acquiring options for this unit: HP #01611-62107 Microprocessor Logic Probe for 8080A, 9080, and Similar Chips HP #10260A Logic Analysis Plug-In Module and HP #01611 62105 Microprocessor Logic Probe for Z-80A and Similar Chips HP #01611-62101 External 8 Bit Probes HP #1540-0325 Accessory Large Carry Case. or other items not listed. Many thanks, Stuart Johnson

VAX vs. Alpha for OpenVMS

by healyzh＠aracnet.com

OK, a bit of an odd question here, but I'm wondering what people think as I'm used to a PWS 433au. A co-worker of mine just bought a VAXstation 4000/90 and a DEC 3000/400. She wants to use one of them as a Mail Server running OpenVMS. The VAX looks to have 104MB, the Alpha looks to only have 96MB. Any idea on which would work best for her? Part of what has me concerned is the lack of RAM on the Alpha. If she uses the VAX, it will probably end up running V7.3, if the Alpha probably V7.2-1H1. DECwindows won't be loaded, which will help get the Alpha down to a better memory footprint. Oh, she'll probably also want to run a Webserver on the system so that the mail can be accessed via the web. Zane -- -- | Zane H.

Richard, Do you still have the manual for the above. I am prepared to pay swap borrow whatever to get a copy or sight of it. I have an old BBC hard drive ( in door stop mode)which uses it so it would be really handy. rgds Geoff Castle Computer Services Ltd.

HP nixie tube module information needed (fwd)

by bill＠timeguy.com

I asked my partner, and here's what he came up with about them. Hope it helps. ---------- Forwarded message ---------- Date: Tue, 20 May 2003 16:41:52 -0500 From: Chris Radek <chris(a)timeguy.com> To: Bill Richman <bill(a)timeguy.com> Subject: Re: HP nixie tube module information needed (fwd) On Tue, May 20, 2003 at 04:24:22PM -0500, Bill Richman wrote: > > http://www.ubanproductions.com/Images/nixie1.jpg > http://www.ubanproductions.com/Images/nixie2.jpg All I know is they were used in counters. These have a binary to 1-of-10 decoder made out of photoresistors and neon bulbs (!) in the black box. It's not a HV supply like he guessed. It should be possible to make a clock but he'll have to modify some of them to reset before the usual cycle of 0-9. Resetting at 23:59:59 is probably harder and would take some kind of external logic. They already have a feedback to make them reset after 9 instead of counting to 15 - it just has to be modified. On the other hand if he wants to make a clock, nixies are cheap and it might be better to just leave the counter modules as-is and use some logic more suited to counting the time (which is not 10-based). I'm sorry I don't have a schematic. It should be easy to trace out - it's just four flip-flops and a feedback line for reset.

Practical Electronics CHAMP/Tangerine Microtan 65

by Paul.HILLS＠landisgyr.com

>I still have my ZX80 which preceded the Microtan. I I think they were the other way round. I reckon 1979 for the Tangerine and 1980 for the ZX80. I also drooled over that Microtan and ended up with a ZX81. By the way, there's a superb website devoted to the Microtan 65 here: http://www.geoff.org.uk/microtan_65.htm. It's got scans of manuals, magazines and all sorts. paul >Dave.

8" floppy drive value

by Innfogra＠aol.com

In a message dated 5/23/03 2:42:14 AM Pacific Daylight Time, mikeford(a)socal.rr.com writes: > So, whats an 8" floppy drive in unknown working state worth? > Last I checked Aluminum Breakage is worth 16 cents per pound. Full Height 8" Floppies weigh about 15 pounds so their scrap value is about $2.40 each. Most Scrap dealers like to get twice scrap value when they do an outside sale so a scrap dealer would likely put these drives aside if you offered him $5 each. Hope this helps. Paxton Astoria, OR

Commercial steel wool is oil-coated to prevent it rusting. Philip described his as going black, which I expect will be the result of the oil carbonising in the hot air stream. The result will be a tough coating of carbon that will prevent oxidation. A similar idea is sometimes used for steel tools -- heat until it develops a blue oxide layer then plunge into oil. The resulting blue colour is fairly pretty, and rust-resistant. -- Pete Peter Turnbull Network Manager University of York
