A lot of the talk here is about really BIG machines (fill a rack, or two or three) but how many of us like pocket sized machines? HP 41C? I just found a wonderful emulator for the 41C! http://library.hp41.org/LibView.cfm?Command=Download&ItemID=23212 Is anyone here a sometime member of PPC? ron.

OT: Need power pinout for Dec Hinote Ultra II

by ian_primus＠yahoo.com

I know this isn't on topic yet, it's not old enough, but I thought I'd check here just in case. I recently ran across a really cute little laptop. It's a Digital Hinote Ultra II model P8X. Unfortunately, I don't have the power adapter for it. It uses a small, three pin connector. The bottom of the laptop says that it takes 11V 2.7A, but it doesn't list the pinout of that connector... Googleing didn't turn up anything helpful. So, I figured I'd check here, and if all else fails, I could always take it apart and see what that connector goes to, but I don't want to mess with taking it apart if I can help it. Laptops are always a pain to take apart and put back together... Also, has anyone had experience rebuilding the battery packs in these? Mine is no doubt dead, and I would imagine it would take standard battery cells inside. Once I get this to power up and verify that the battery is dead, I plan on rebuilding it with new cells. Thanks! Ian Primus ian_primus(a)yahoo.com

HP 2000 TSB simulated?? YES! 2000 E, and F and Access have all be en running.

by MGemeny＠pgcps.org

Hi folks, I just want to express my thanks for all of the support that I have gotten this week from the group. Thanks you all so much. It has been wonderful chatting with so many people with interest in the HP2000 product line. For anyone who I have not already told, I did start up an HP 2000 Access simulation for people to play with. Please don't invest a bunch of your time keying in things as I'm not keeping a regular backup schedule. If I have problems with it, I'll just reload it from the last backup tape image. I have a web page that has a link on it to start your telnet session and it also gives you a few tips and pointers. This will also give us a place to link to other web pages and running systems. <http://www.pgcps.org/~mgemeny/access> http://www.pgcps.org/~mgemeny/access This image has a lot of other accounts on it, and they have a lot of programs in their catalogs. If you want access to more of the system, just drop me a note. I would be glad to send you instructions on how to browse deeper into this system. From the response I have gotten I would estimate that several systems will be running 24/7 by the end of next month. So user accounts on stable systems should be available. I would also guess that we will be grooming SIMH for another 6mo or so and that much progress in recovery of libraries will take place over the coming year. And, by the way, since this thread did start out talking about star-trek, one version is in your group master account. For a listing of the group type "gro", to get a program from this list just put and "*" in front if the name. The break key is not working yet so you may want to list it and know how your going to get out of it before you run it. Please report hung port to my email. Don't be shy about it, it's not your fault, it's mine. Please don't make too much of a mess. You won't be hurting me, just preventing others from enjoying the same pleasure you had. Enjoy, and Thanks again, Mike Gemeny.

Byte Magazines

by roger161uk＠yahoo.co.uk

I have the following issues of Byte Magazine. Unfortunately, they take up a fair amount of space on my office shelves and, as a result, I am contemplating getting rid of them: despite them containing loads of good information, I just don't have time for it anymore :-( Anyway, individual copies are available if anybody has a collection with missing copies and, I am happy to send larger numbers of copies to anybody interested in them, the only provision is that postage and packing must be paid, at cost (or thereabouts), by the receiver. If I receive numerous contacts for specific copies of magazines, or for specific series I may place the magazine or series on eBay or another auction site as a means to resolving the contention, proceeds going to a local old folks home. All are in good condition, although clearly some are in better condition than others. I herewith enumerate all copies, as I do not have a complete set - certain months/years are missing. January 1988 December 1989 May 1989 September 1989 February 1990 March 1990 April 1990 June 1990 January 1991 April 1991 July-December 1991 January-November 1992 January-December 1993 (except February, July and October) January-December 1994 January-December 1995 (except for August) January-December 1996 February-December 1997 January-April 1998 July 1998 Best regards, Roger ________________________________________________________________________ Want to chat instantly with your online friends?

PDP8A Questions

by nbreeden2＠comcast.net

All, I was recently given a PDP8A, it's the model with dual power supplies and the 20 slot backplane. It has both the mini-panel and the operators panel. I've been working to get the system operational and have several questions: ===== The unit won't power up, I have been able to troubleshoot this down to the Triac (D7) on the BA8-C that is used to switch AC power to the main transformer. I believe this Triac is bad. (Note: I do have AC power to T1 on the BA8-C PCB.) With the Triac bypassed the system comes up and basic items check out from the operators panel. Does anyone know what a replacement Triac part number would be? I only see what I believe are DEC part numbers. ===== In the print set for the BA8-C the circuit that controls AC power is shown, the circuit uses an opto-isolator. In the schematic one side of the opto-isolator's LED goes to J12-B2, the other side of the opto-isolator is labeled OC1-2 (OptoCoupler 1 pin 2 I assume). Does anyone know where this pin actually goes? ===== I'm assuming that the G8019 board controls switching of the AC power via the opto-isolator. Is this a correct assumption? ===== I have an RL02 controller/drive/disk with the system, what steps do I need to take to boot from this drive? I don't have an operators manual at the moment. ===== -Neil

Kennedy 9622 SCSI 9-track manual?

by waltje＠pdp11.nl

Hi all, I got a 9622 on loan so I can read some old tapes. Sadly, the thing is semi-dead, so I'll have to do some maint on it first (basically, replace its fan, clean it out completely and reset its SCSI ID to something other than 0 ;-) Does anyone have a manual of this beastie? Cheers, Fred -- Fred N. van Kempen, DEC (Digital Equipment Corporation) Collector/Archivist Visit the VAXlab Project at http://www.pdp11.nl/VAXlab/ Visit the Archives at http://www.pdp11.nl/ Email: waltje(a)pdp11.nl BUSSUM, THE NETHERLANDS / Sunnyvale, CA, USA

Simple serial to ethernet question

by jpl15＠panix.com

Regarding the recent (very much info!) thread about serial to network devices, terminal servers, etc... I have a Dumb Analog Engineer Question. And my DAEQ is this: I gots a DEC PDP 11/44 sitting in my garage (heated) and I would like to have the Terminal Peripheral Devices (TPD) in my Office (O). I just want a couple-three VT-type thingies and an LA120, or 36 or whatever. So, if I understand Things: I hook N ports from the 11/44 serial farm via RS232 to the ports on the TS, thence by CAT5[some_networking_protocol] to the TS in the O, and from the corrresponding N ports ports on the O TS to the various TPDs in the aformentioned O. Right? This saves running multiple RS232 lines from the 'Puter to the Toobz, among other things - like being able to play with one's Legacy Computing Device (LCD) whilst slaving away at the Workplace.... And, if a pair of Terminal Servers is what I'm looking for - I assume 8-channel pairs are cheap? Any reccomendations for this specific task? Cheers John

Telling DECTape & LINCTape Drives Apart?

by aek＠spies.com

Physically speaking, how do you tell the difference between a DECTape drive and a LINCtape drive? -- By the time PDP12's were built, DEC was using the same transport (TU55's, later TU56's) for either format. LINCtapes are loaded on the right-hand reel, and forward tape motion is counter-clockwise. DECtapes are loaded on the left-hand reel and forward tape motion is clockwise. The only other gotcha is the timing track is the opposite polarity between the two formats.
