Via the Dayton Hamvention and Dan C., I now have a nice "new" corporate cabinet for my 11/23+ and two RL02's, installed and working. It came with an 874-D Remote Power Controller which I would like to use as intended (i.e. turn everything on by flipping the BA-11SA front panel power switch). That switch connects directly to a 3-pin male Molex connector on the rear of the BA chassis. The 874-D has several 3-pin female Molex connectors labeled "DEC Power Bus". Am I correct in assuming that I just need a 3-wire extension cable between the BA chassis and one of those Power Bus connectors? If so, is there a DEC part I should be looking for? If not, any ideas which mating connectors to order (it's not critical that I use factory original pieces)? The two connectors are not identical families (the BA-11SA's connector is flat on one side and rounded on the other; on the 874-D they are rectangular). Thanks for any help. -Charles

Any Palm developers on the list?

by ethan.dicks＠gmail.com

Hi, I have been dusting off some old Palm Pilots (III and V, mostly) and am running into "decayed link" syndrome on most of my searches. I'm finding fragmentary web pages and links to abandoned projects from 7-8 years ago, and only a few things that encompass what I'm working with. I joined the Palm Developers Network, but they don't make older SDK files available for download. I'm really looking for the kit they used to have available that allows one to develop PalmOS 3.3-era stuff - so around 1999 or so, I think. Does anyone on the list have something that sounds like that? If so, please reply to me directly rather than clutter the list with stuff about Palms. To tie this search into recent events, I did see a few, very few, Palms at Dayton. The best price I ran across was a Palm V w/cradle and wall wart for $10 (and another for $15 with box). Unfortunately, that's more than they go for elsewhere. I got home and ran across a Palm Vx at the nearby thrift for $6.99 w/cradle and wall wart (along with a Garmin 12 GPS for $1.91!) Since the DragonBall is essentially a dressed up MC68000, I've always appreciated the PalmPilot innards, but I've never had a need to build my own apps. These days, everyone wants to support the Tungstens and Treos, etc., and have left monochrome Palms in the dust. Thanks for any assistance in locating ancient development tools. -ethan

FOG DOS discs archived anywhere?

by aek＠bitsavers.org

There are around 400 MSDOS group discs produced by FOG. There were only a couple on the FOG cdrom, does anyone know if these have already been archived? They appear to span 1986-1990

Price vs value for DLT tapes

by ethan.dicks＠gmail.com

All, I have the chance to get an inexpensive "HP DLT40" drive or two... >from my googling, it seems that these drives can read/write DLT III (10GB), DLT IIIxt (15GB) or DLT IV (20GB) tapes. Are DLT IV tapes (20GB uncompressed) worth the effort of tracking down and shipping? We pitched out several hundred new-in-box DLT IV tapes from South Pole over six months ago, partially because we hadn't unwrapped one in over 4 years (we had moved up to SDLT @ 110GB each, some time prior to 1 Jan 2003). Old though they are, I'd consider an inexpensive SDLT drive and a stack of tapes to be a somewhat useful density to use for backup on any system I have lying around. What's not as clear, though, is if tapes that hold less than 20% of that are worth more than the cost of shipping. At the moment, I can get a couple of drives for essentially free (under $5, and, no, not at Dayton). What concerns me is the expense of the tapes, and more from a shipping standpoint than an actual per-tape cost. If we were throwing out these tapes last year, I can't imagine that I can't find someone else doing the same this year - it's just a matter of how much it costs to receive them. Given the things I'd like to back up (laptop, main Solaris file server), I'd want to be able to rotate tapes in a sensible scheme so as not to write to the tapes too often, but I have enough stuff to cover that one 20GB tape per month just isn't enough; I'd need several tapes per month at that density. Over the course of a year, I'd probably need tens of tapes, but perhaps with a higher density (SDLT, say), I could get away with a dozen or so tapes per year, but the drive and tapes wouldn't be as close to free as DLT IV (I've seen eBay prices on SDLT drives in the $20-$50 range). We stopped using SDLT at Pole last year (2006 data was written to SDLT and Ultrium tapes), so, again, I can see that the modern world isn't going to be as interested in them as some of the newer, multi-hundred-GB-per-tape schemes. I guess another way to phrase this might be, does anyone on the list know of a source of extremely inexpensive piles of DLT IV or SDLT tapes - either density media quickly adds up to more than the present cost of drives, so in the end, it's the weight of the tapes that's the limiting factor. Thanks, -ethan

The real differences are bug fixes. Essentially the RQDX2 is a bugfixed RQDX1 with later firmware that is aware of a larger (at that time) assortment of drives. In the real world of MSPC controllers RQDX3 is most desireable and RQDX1 the least. FYI: some flavors of RQDX1/2 didn't pass interrupt grant and MUST be the last card in the chain. Allison

Rainbow graphics card only $89.63! Give me 10!!! http://cgi.ebay.com/DEC-54-15688-RAINBOW-GRAPHICS-CARD-5415688_W0QQitemZ120… Honestly, who would be using such a pig these days? The price this guy is asking is indicative of his belief that someone actually NEEDS a card for his lousy 'bow. I ran into a guy in Kentucky who wanted extra TI PC's, being that the software he used for some geological surveys he made a living off of ran on them. But that's a highly unusual application.

Friden Flexowriter

by sethm＠loomcom.com

Well, this is either the stupidest thing I've ever done, or a really cool find that will fill me with joy. I just won a Friden Flexowriter on eBay (Item #180115571829). I've been looking for one of these for almost ten years, and up popped this one, with no bids but mine. It's almost local, so I'll be picking it up in person to avoid shipping. It'll cost more in gasoline, but it should protect against the danger of shipping damage. I'd love to hear from anyone else who has one, or who has worked on one. I've downloaded the MIT memos regarding the operation of the PDP-1 and TX-0 Flexowriters from Bitsavers, but that's literally all the documentation I have. I'm not even sure what character set this one has -- it is lacking the upper-case symbols on the number keys, for instance, and the "1" key seems to be on the right ("2, 3, 4, 5, 6, 7, 8, 9, 0, 1"). I understand they were frequently customized with their own character codes, as well. The Flexowriter in question is "not working", although it looks like it's in excellent shape physically. I've become quite handy with typewriter mechanisms recently (don't ask), so I'm hoping that whatever the problem is is fixable without terrible difficulty. If not, I'm close to Los Altos Typewriter, who (I believe? I'm not sure on this) repaired the Soroban console for the Computer History Museum's PDP-1. Wish me luck with this potential white elephant. -Seth

Free Computers in New Haven CT.

by woyciesjes＠sbcglobal.net

*** Please reply to me directly. I'm way behind on my ClassicCMP reading... For various reasons, none of them good, I have a couple of computers, and some cables & parts, that _must_ disappear from my house ASAP. At this point, I'm not worried if I get anything for them. But I won't turn it down cash (or good beer) in return. I'd rather not have to ship them, having lack of time. Here's a quick list of the machines. IIRC, they don't have HDDs. More info available upon request. - Mac SE/30, with network card not installed. - Cardinal PC10. 386 CPU, looks like a Mac SE, with a 10"(?) color screen. - Digital Multia. - Digital Alpha 200MHz? with plans on how to adapt an ATX power supply for it. IIRC, there might even be a ready made adapter. - Dell Optiplex P4 1GHz, 512MB RAM. Spare MB w/CPU, PCI riser & power suppply. - Compaq PIII 600(?) small desktop, 256MB RAM (?) - SuperMicro P4DP6 server class system, 1GB RAM, 2GHz Xeon (can take 2).

PDP-11/8x memory cards.

by bqt＠softjar.se

I just verified that M8637-Ex cards works fine in both 11/83 and 11/84 systems. The same goes for M8637-Dx cards. I don't think I have any M8637-Bx or -Cx cards, so I can't try that. So to make it clear: MSV11-JD and MSV11-JE works fine in both Q-bus and Unibus systems.

If it were a data acquisition board surely it would have ADC's not DAC's? The use of DAC's surely implies an output board of some kind. The use of standard DB type connectors and lack of trim-pots etc. would seem to support this. Jim

It loads from the system. If there is a ROM it would most likely have such a name. Do remember that the 8086 was a full 16 bit bus. There would most likely be 2 ROMs and the ascii may be split across the two to read as on contiguous text from the bus.

MGE EPS 2000 UPS available

by ingrammp＠earthlink.net

Ok, it's not a computer, but it's certainly computer related... i have an MGE systems 50KVA UPS available that we just removed from service yesterday. Unit has been running for 10 years ( we moved up to a newer unit ) under maintenance from MGE. This is a 480VAC 3phase input, charging a string of 40 batteries at about 512 volts, and providing an output of 220 3phase through a step down transformer. It's a big heavy thing, approx 1700 lbs for the UPS and same for the battery box, in a stage of partial disassembly now ( to get it out of the room it was in ). Best part is it's free... just come by and pick up ( liftgate truck is required... its heavy and we don't have a loading dock ) We're located in Tucson AZ. It should be a matter of nuts and bolts and having a good electrician to reassemble this fellow if you wanted to bring the whole thing up or.. if you have one of these, it's a great source of spare parts ( since they aren't made any longer ) Mike

Howdy, guys. I've got an 8-bit ISA card here that I pulled out of an IBM PC/AT 5170 machine (which apparently was a VM/PC development machine at one point, and contains program code for the PC3277/GA). I wondered if anybody could help me identify what it might be. Parts have date codes in 1985; chips of note are 32k in 70ns 4Kx4 SRAM; intel 8086, 8259, and 8254; and a pair of 12-bit monolithic DACs. I/O is by one DE9m and one DB25m.
