HP 2116 restoration: Feasiblity and "what to look for" advice needed!

by colineby＠isallthat.com

Jules,? Excellent! That's really helpful. I've seen a crate of 21xx cabling and gubins as ?which?needs?investigated, and there's a whole room of HP goodies to sort, not to?mention a handful of later related systems. I have the tape drive back at the house for a clean and checkup. It looks pretty hopeful, but will need a few things. -Colin Eby Jules Richardson <jules.richardson99 at gmail.com> wrote: Colin Eby wrote: > All, > > I've located two HP 2116 systems, a B and a C. Hi Colin, I'll save you a little bit of effort (at least on the 'B'), as here's my catalogue of the very same machines from four years ago :-) ?? http://www.classiccmp.org/pipermail/cctalk/2007-November/063044.html ... although I never did get chance to look into whether the 'B' system had any 'hidden' core. It was about a fortnight after posting that message that all my visa stuff went through and I hopped the Atlantic permanently to the US,? so I never did get the chance to do any more with either system. cheers Jules

"Previous": a 68K NeXT Cube emulator

by lproven＠gmail.com

As a friend has just given me, gratis, a full copy of NeXTStep - 3.0, with upgrade CDs for 3.1 and 3.2 - I thought I would go looking for some way to run them, as I have yet to find a NeXT box that is both [a] complete and [b] which I can afford. It's not there yet, but this looks interesting and promising... http://forums.omnigroup.com/showthread.php?t=20126 -- Liam Proven ?

HP 2116 restoration: Feasiblity and "what to look for" advice needed!

by colineby＠isallthat.com

All, I've located two HP 2116 systems, a B and a C. I've also got access to period Teletypes, 2748A paper tape reader requiring restoration, and the uncatalogued back stores of a museum. I'm strongly considering a restoring one working system from the two for museum demonstration and display. If you were me, or have had experience with these systems before, what would you keep in mind or look out for? Assume for the moment I have the time and skills myself or available from colleagues to carry out the work. All thoughts and contributions gratefully received. Some background and progress: * neither system has been in "conservation friendly" storage conditions. * the museum has fairly extensive HP collection, which makes missing component location more likely if required * the museum also has a range of HP instruments which might be used to create an interactive industrial control or scientific computing display My first steps so far: 1. Conduct background reading research using internet sites and scans. Thanks to all the following for making these resources available * Al and Bitsavers, * http://www.cs.ubc.ca/~hilpert/e/HP21xx/HP2116.html (B Hilpert) * http://rikers.org (Tim Riker) * http://www.hpmuseum.net/ 2. Begin basic physical evaluation of the "C" system: a. Basic cleaning of the cabinet and vacuuming out of components -- so far excluding the card cages (ran out of time) b. Begin inventorying components and starting photographing them The verdict so far is that environmental damage appears limited to the front panel and some limited contact corrosion on the chassis and panels. There's mildew evident on the some cabling, but not really showing on what I've seen on the backplane wire-wrap so far so far. The cards are in a muddle though. This is what I've catalogued: ================================================= <Rack 1> 1 - 22 EMPTY <Rack 2> 101 A101 Front Panel Coupler 102 A102-105 Arithmetic Logic 103 A102-105 Arithmetic Logic 104 A102-105 Arithmetic Logic 105 A102-105 Arithmetic Logic 106 A106 TIMING GEN (clock) 107 A107 Instruction Decoder 108 EMPTY -- Missing A108 Shift logic (this could be in the loose boards) 109 EMPTY 110 EMPTY 111 EMPTY 112 EMPTY 113 EMPTY 114 EMPTY 115 EMPTY 116 EMPTY 117 EMPTY 118 EMPTY 119 EMPTY 120 EMPTY <Rack 3> 201 A201 I/O Control 202 EMPTY 203 EMPTY 204 EMPTY 205 ?? *not yet identified* 206 A13 MDB (this is supposed to be in slot 13?) 207 POWER FAIL (not sure what this is in relation related cards 208 POWER FAIL 209 POWER FAIL 210 POWER FAIL 211 ?? 212 A4,6,16,18 Inhibit Driver (should be in the 2116 B according to #1) 213 A4,6,16,18 Inhibit Driver (should be in the 2116 B according to #1) 214 A4,6,16,18 Inhibit Driver (should be in the 2116 B according to #1) 215 A4,6,16,18 Inhibit Driver (should be in the 2116 B according to #1) 216 MMD / XV Driver ( should be associated with a core board ) 217 SSA ( should be associated with a core board ) 218 A2 219 A8,9,14,15 Driver Switch (should be in the 2116 B according to #1) 220 MDB ( system should only have one of these ) 221 EMPTY 222 EMPTY <Loose> Looks like two or three core stacks and four cards: POWER FAIL ?? ?? ?? =================================================== Given that some of these cards look like they are from the wrong machine, all the memory slots are unpopulated (some are stuck in the IO rack), I'm guessing that the guts of this system have been mixed and matched with others, possibly the "B" model -- either that or just shuffled. I won't know until I've started to look at the "B" model for comparison, and of course, completed the cataloguing of this one. -- Colin

Information on the PPS-4/1 4 bit microprocessor wanted

by tshoppa＠wmata.com

> The PPS-4 was actually a bit more 'sophisticated' than I > first thought. One other thing that was unexpected was > that they are powered eg. 0 and negative 9V. I wonder why it's like that... The early 70's LSI was mostly PMOS. Simpler devices were often a good match to a 9V battery in handheld devices where that was the target. You wouldn't believe how much effort was put into putting LED drivers on the same chip where they could (often they couldn't and the LED driver was off the main logic chip.) More complex PMOS logic often had special supplies for clock and enable lines. You often find small switching converters (magnetics or charge pump) to generate the required voltages. A little later high-density NMOS also would use oddball voltages (both positive and negative depending on application) for density's sake. e.g. 8080A. Some good examples of how some handheld devices generated the necessary oddball voltages at http://www.jacques-laporte.org/HP35%20power%20unit.htm Tim.

Thinking of selling collection

by snhirsch＠gmail.com

All, I think the time has finally come to narrow down the scope of my collection for the sake of space, marital bliss and sanity. I need to shed a healthy assortment of Unix workstations, most in operational form. I have printed docs for some and DVDs full of software for all. Not looking to get wealthy, but I would like some modicum of reimbursement given the condition and completeness. I will not ship any of this - you must come to Burlington, VT and take it away (or arrange to have that done). Would love to have the entire collection go to one person (and will adjust fiduciary expectations accordingly). It will take some effort to pull together a detailed list, but here's a rough rundown to guage interest: IBM RS/6000 43p - Complete set of AIX 4.3 media - Has 100Base ethernet adapter installed HP Visualize B2000 - Complete set of HPUX 11i distribution media - Complete set C/C++ development tools SGI Iris Indigo R3000 - Basic machine - no 3d graphics SGI Iris Indigo R4400 - Every option known to Westerm Man, including 3d graphics (I have a couple of Iris Indigo keyboards and mice. These are not common items) SGI Indigo 2 (Teal) R4400 CPU SGI Indigo 2 (Purple) 768MB Memory, Uber hi-end graphics board, 100Base ethernet. I _think_ it's an R8000 (IP26). Sun Ultra 5 Sun Ultra 2 Sun Ultra 60 - Very tricked-out machine with 2x 450 Mhz. SPARC cpu and lotsa memory. Has U160 SCSI controller. (I have Sun keyboards and mice a-plenty) (I also have a gorgeous, early Sparc 2 with a box of S-Bus cards, but I'm planning to hang on to it) --> Lots and lots of Solaris distros on CD and DVD. 2x DEC Alpha Multia. I know one is operational. Slower than death warmed over, but very high "cute" factor. DEC Alpha PC64 w/ 256MB of memory in PC case. Operational system DEC Alpha PC164 motherboard (maybe 2..) DEC Alpha UP2000+ system w/ 2x 700Mhz. 2MB cache 21264 - This is a beast. Huge power supply, Adaptec 29360 controller, several disks. - Was my pride and joy until it went flakey. Might be good for parts or a demonstration of poorly-characterized electromigration on ageing VLSI parts. --> I have several complete sets of install media for Digital Unix 4.x through Tru64 5.something. License keys for everything. - I have 2GB of memory for it, but the machine won't POST with it installed. DEC 5000 MIPS-based workstation (bare system, but works last I knew) DEC VAXStation 3100 - Condition unknown - Have a box of VMS 5.x docs, Ultrix CD, Full set of VMS media. Also: Boxes full of spare boards and widgets for many of the above. Full 5-ft. Shelf of documentation on the Alphas I'm not exaggerating when I say this will fill a van :-) Please feel free to drop e-mail with additional questions and/or interest. I really would hate for this stuff to end up on a barge to China for gold reclamation... Steve --

cctalk and cctech List subscriptions

by ljw-cctech＠ljw.me.uk

Due to the large number of pending subscriptions to cctalk and cctech I am about to 'reject' all of them and request that anyone still waiting to subscribe please re-subscribe at which point they will be approved quickly. Please make sure you only request subscription to one of the lists. To re-iterate: cctalk is un-moderated, cctech is moderated cctalk is a superset of cctech Anything posted to cctalk appears immediately Anything posted to cctech is cross-posted to cctalk immediately Anything posted to cctalk OR cctech is (cross-)posted to cctech if the moderator (me!) feels it is on-topic - therefore they will always be a delay before postings appear on cctech There are some posts in cctech which are bypassing moderation - we hope to sort this out soon. -- Lawrence Wilkinson lawrence at ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360

hp calculators

by dgriffi＠cs.csubak.edu

I'm about to get something to replace my old TI85 I had from high school. Lots of you here rave about the HP's offerings. Indeed, I wanted to get, but couldn't afford an HP48g when they were new. I don't have much need for graphing now, but I do need scientific calculation. The HP35s seems good for that. Or should I just jump in and get the HP50g? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

> I am also the proud owner of a Mattel Battelstar Galatica anno 1979 week 14. > > The chip used in this vintage handheld game is labeled B6001EA > and I guess it's a Rockwell International PPS-4/1 micro controller > (a PPS-4 cpu with clock, ram and rom) from sources I found on the net. Many of the Mattel games of that era were variants on Rockwell calculator chips. Not unrelated to 4-bit general purpose CPU's of the era, but the game chips were way closer to the calculator chips. Read the interview with the game's designer, Mark Lesser: http://www.digitpress.com/library/interviews/interview_mark_lesser.html Tim.
