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

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

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

RDI PowerLite 110 and OpenStep - watchdog-reset

by ian.finder＠gmail.com

Hi folks, So I recently made a very poor trade for an RDI PowerLite 110 under the assumption that it could run NeXTstep or OpenStep, as allegedly RDI supplied the PowerLite with this OS in some configurations. The PowerLite is essentially an SS5 in a chunky, ugly laptop. When I boot the OpenStep and NeXTstep installers however, at the second stage loader I get a "watchdog-reset" message from OBP. Ultimately it's the same issue as discussed here: http://www.nextcomputers.org/forums/viewtopic.php?t=3153&sid=b8cb75adb72457… Any hope in getting this to run? Any ideas out there? Or am I stuck with a fat ugly wannabe SparcBook 3? (I have a few of the 3GX/3TX family which seem like far nicer machines, the only reason I wanted this RDI P.O.S. Is the weitek framebuffer in the SparcBooks isn't supported by OS/NS, but the CG6 in the RDI supposedly is. What a garbage machine RDI produced with this one... Thanks, - Ian

However the page you sent for Datacraft 4441 shows it to be a CDC Hawk drive. The 9425 was first made by NCR. It moved from California to Oklahoma when CPI and MPI were formed. The early version 9425 Cartridge Disk Drive was not a good product. It was re-engineered into the 9427H, code named Hawk. Both were 5MB fixed, 5MB removeable cartridge. Available as a rack mount or stand alone cabinet. There were 4 different types of plug in interfaces available. As near as I can remember, there were around 350 different configurations in production. Most were variations on the color(s) of the skins. But there were also options for sector count, power supplies, front name plate, terminators, cables, etc. Without the original configuration data, it is hard to look at a Hawk and tell what was in it and who was the OEM customer. Customer base was like a who's who of 1970s - minicomputers to early microcomputers. There were even a few S-100 controllers for it There was a 2 disk fixed only version called the Falcon. Really brings back the memories. Billy

Framebuffer driver for RDI BriteLite IPX?

by derschjo＠gmail.com

Hi all -- Sent this query to the Rescue list last week, no bites. Any Sun fanatics here have any ideas? (Linux/OpenBSD appear to support it, but I'd rather keep the OS vintage-appropriate. For some reason...) Got myself an RDI BriteLite IPX; a "laptop" (a generous description) based around a stock SPARCStation IPX motherboard with a very large laptop-style enclosure around it, a 640x480 active-matrix LCD (very pretty) and a gigantic lead-acid battery. It has a handle, so it's portable! Anyway -- I have it up and running and I have SunOS 4.1.4 installed on a fresh hard disk (the original drive was long gone when I got it). Unfortunately, the LCD framebuffer is unrecognized by SunOS; it identifies itself as cgRDI and it's a custom SBUS board that drives the 640x480 LCD. From what I've been able to dig up this driver was packaged as "RDIlcd" by RDI but I can't find it, of course. Anyone happen to have this archived somewhere? Any other ideas? Thanks, Josh

Online Access to Running AOS/VS Offered

by steve＠stephenmerrony.co.uk

I've had a lot of help from all over the world getting my Data General MV/2500 up and running, so it's time to give a little back... I am now able to provide on-line access to my operational MV/2500 DC to individuals who make reasonable requests for it. Currently the machine is running AOS/VS 7.70 and has little other than the base software installed, although most of the NADGUG library contents is available. I am not willing to run the MV/2500 24x7, so operational times will be by mutual agreement. I strongly suggest using DasherQ to connect. Access is via telnet provided by a Raspberry Pi acting as a serial-to-network gateway to real serial ports (I don't have TCP/IP on the machine yet). If anyone would like access to the machine please email me stating why you would like access (even if it is just for nostalgia!) and what time zone you are in.

Memory options for an HP 1000 (HP 21MX / 2112A)

by marc.verdiell＠gmail.com

Yes I was asking myself the same question, and your answers continue to help a lot. I think I should retrace the path of technology evolution. Start getting it up with paper tape tests and BCS. That probably means working mostly in assembly and getting to know the most basic level of the machine. Which is just about what the doctor prescribed. Then add the mag tape for which I have the tape and the cards. I got a 7900 disk though (with cables and power supply, but no interface cards to go with it!). I'd love to get that one going later on. Then it would make sense to have the bigger memory to run disk based OS systems. So 7900 interface card and memory are definitely on my hunt list... By the way I also have a punched card reader which I just restored. Documation ML600, but the exact same model that HP re-branded I believe. Do you know which interface cards I need to connect it to the HP-1000? I suppose one of the 16 bit IO ones with a driver to go with it? Sorry to keep picking your brain, but that is so much more efficient than trying to piece it together (usually wrong at first) from an disorganized pile of documentation! Marc From: "J. David Bryan" <jdbryan at acm.org> >> So I might be in the hunt for the cards or alternate solutions you >> mentioned. >I'd suggest that the question to answer first is whether you want to expend >the effort and expense to gather the moderate amount of additional hardware >necessary to run one of the more advanced disc-based OS versions that can >use DMS.

More HP-1000 Parts - Get 'em while they last!

by hpfparts＠yahoo.com

I recently posted reference to a page on my personal web site listing HP-1000 assets for sale. There was a flurry of interest. As of this afternoon, the last of a half-dozen boxes were shipped to the new owners of many of these items. Thank you to everyone for their interest and thank you for your patience. Several individuals have expressed interest in acquiring more parts. The good news is that I still have items left. The bad news is that the 256k and 128K memory boards, +True In/Out, Term, Timebase, Error Correct, FPP Arith, and FPP control cards are all gone. So consider this fair warning: If there is something else you need to restore your system or to build a reserve of spares, now is the time to grab it before it's gone, too. The inventory sheets have been updated on my site to reflect what is left. Some items are being offered piece-by-piece, some I'd prefer to sell as a set. Details are on my site. www.hpfriedrichs.com/hpfparts/hpfparts.htm 73, Pete AC7ZL

54 TK50 tapes on eBay

So much for "YMMV": jkunz and I must have had some really bad tapes back then at the VCFe a couple of years ago. When we tried to read them (in a TK70, I think - does that make the difference?), they slowed down the mechanism, produced a squealing sound and stuck to the head to the point where in some cases the tape (carrier) broke in some cases. We did clean the head and tape guide parts with IPA several times only to get the same problem again. I'm sure he can elaborate a bit more about the tapes and the equipment used but I think I have it mostly correct. So Long, Arno

HP 9144A and three QIC tapes available for free

by p.gebhardt＠ymail.com

Hi list, 3 years ago, I picked up an HP 9144A QIC tape drive with HP-IB interface. It came with three 16-track QIC tape drives. I never found the time to connect it to my HP 9000-300 and realized that I will probably never make use of it, which is why I'd like to give it to some other collector's hands who is interested. I powered up the drive for 2 hours, no smoke, the fan was running as expected. Nothing else tested. Picture of the actual three tapes which come with the drive: http://www.digitalheritage.de/OTHER/20141223_155006_tn.JPG I forgot to take pictures of the drive, but will do it, as soon as I can access it next week again. In the mean time, here is another one of the tape drive (not mine): http://www.hpmuseum.net/display_item.php?hw=257 The drive weights 9kg (20 lbs). First come, first serve. Drive and tapes are for free. You have to pay shipping costs or come to pick it up. Location is Bonn, Germany. Kind regards, Pierre ------------------------------------------------------------------------------- Pierre's collection of classic computers moved to: http://www.digitalheritage.de

network event

by jwest＠classiccmp.org

Yesterday afternoon we had a "network event" on our storage network. Traffic was flowing, but with severe drops in connections. We believe we have most - but not all - resolved at this point. Unfortunately, in the thick of battle production machines come first so classiccmp server sat down for a while and was just brought back up. Apologies for the inconvenience.. Going to sleep now. J

Looking for RL11 (Unibus RL02 controller)

by derschjo＠gmail.com

I've been using my lone RL02 with my QBus systems, I'd love to be able to use it with my 11/34 as well. (If anyone has a spare RL02 *drive* I'd be interested as well...) I have various DEC stuff for trade, drop me a line if you have one going spare. Thanks! Josh

Memory options for an HP 1000 (HP 21MX / 2112A)

by marc.verdiell＠gmail.com

Dave, Super useful info again. In the meantime the machine has arrived, in very good shape. I'll post pictures when I have time tomorrow, and a video hopefully. I took a quick look inside to confirm - there is a DCPC and a MEM protect card - Memory controller is an older 2102A - Three are three 8k 2102A memory boards - No MEM card in slot 112 - Under the processor board there is a screwed on card, which seems to have ROM on it. Microcode I presume, but I don't know if that's the one you were talking about. I'll post photos to confirm The IO cards and the paper tape reader / punch that came with it suggest that it was configured with a paper tape reader, a paper tape punch, a mag tape and a TTY interface. A plausible story is that this was an early machine setup for paper tape and TTY and didn't have extended memory. The early 2102A controller fits that picture well. So I might be in the hunt for the cards or alternate solutions you mentioned. Marc From: "J. David Bryan" <jdbryan at acm.org> On Tuesday, May 19, 2015 at 23:12, Marc Verdiell wrote: > Thanks, very useful info, and the manual is indeed what I was missing. You're welcome. > But now where to find the DMS, with two cards in particular, that's > not going easy to find both that match... First, are you sure that the machine does not have DMS installed? It was a very common option that became standard later on, as all versions of the RTE operating system after RTE-II (circa 1976) required it. Second, if the machine originally came with DMS but was stripped for resale, then possibly only the MEM card (in slot 112) was removed. The firmware card is screwed onto the CPU board on the underside of the machine and is only accessible if the bottom cover is removed. So maybe it was overlooked, and the availability of MEM cards is likely to be reasonable, as the same card (but with different firmware) was used in the E/F-Series machines. Third, if the machine has neither DMS part, then indeed finding an M-Series DMS firmware card might be difficult. However, DMS firmware was also included with the later M-Series Fast FORTRAN Processor firmware (product number 12977B). Again, the FFP was a common option, and availability of that card might be better than the older standalone DMS firmware card. Fourth, if you can find a standalone MEM card, the M-Series DMS/FFP firmware source is part of the HP 1000 Software Collection on Bitsavers, so you could burn the required firmware PROMs and install them on a 12791A Firmware Expansion Module card, which plugs into the I/O backplane and cables to the CPU board. Both the FEM and the MEM were used on E/F-Series machines, so availability should be reasonable. Finally, the simplest HP operating system that used DMS (RTE-III) had additional hardware requirements: a Memory Protect card, a Dual-Channel Port Controller (i.e., DMA) card, one of several console I/O cards, a Time- Base Generator (i.e., clock) card, and either an HP 7900A or 7905/06/20/25A hard drive and its associated I/O interface(s). The latter may be the most difficult and expensive part. You can avoid the hard drive and use Ansgar Kueckes' HPDrive emulator with an HP-IB I/O card, but that requires RTE-IVB as the minimum OS, which requires at least 96KW of memory (128KW if you want to do anything other than boot the system :-). MP and DCPC also were exceedingly common options, so I'd be surprised if your system didn't contain them, unless they've been stripped out for resale. Without DMS, you're limited to 32KW. In that, you could run (with some additional hardware, most notably an HP hard drive) DOS-III or RTE-II. Without a hard drive, you'd be limited to running one of several paper tape or mag tape-based HP OSes. There are third-party OSes that run on the 1000, but I know nothing about them. At least software is no problem; virtually everything that HP developed for the 2116/2100/1000 machines is available via the Bitsavers collection. -- Dave

8-bit Computer TV Channel Use

by nf6x＠nf6x.net

I've been brainstorming about hypothetical hardware for converting video from vintage 8-bit computers to drive modern monitors well, with support for all of the dirty tricks like color aliasing that many of them used. One of the things I would like to understand is the range of RF frequencies used by the machines that connected to ordinary televisions. My old Color Computer used US VHF channels 3 or 4 for NTSC video. I found a reference to the ZX Spectrum using UK UHF channel 35 for PAL video. What other channels were used all over the world by 8-bit home computers (and video games, too, I suppose), and which TV standards were used with them?

hp 1820-7730 datasheet? HP-PB J2146A LAN interface, SOT23 part missing

by Arno_1983＠gmx.de

Hello Folks, with a bunch of HP 9000 equipment, I received a HP-PB "802.3 10Mbps LAN" card that was missing the 10base2 BNC connector and the SOT23 SMD part directly behind it. No idea why and by whom they were removed. A BNC socket was easily found in one of my parts bins, but what about the SMD component? My first idea was this might just be some sort of transient protection device (I've seen a really old ISA NIC fitted with a neon bulb next to the BNC for that purpose!) but there probably is a bit more to it, as pin 1 connects to BNC Center and to pin 7 on the PHY (U18, NatSemi SS9130AP also HP house-marked as 1820-7730), pin 2 is BNC shield/ground *and pin 3 goes to pin 5 on the PHY*. Unfortunately I was not able to find a datasheet for the PHY that would probably give an example circuit - can anyone please either point me to that or, if they have an example of that card available, look up the marking of that SOT23 device for me? Card would be for my HP9000-K100 PA-RISC, for which I'm also looking for one of the graphic options. One keeps popping up in the US 'bay but the (commercial) seller wants real money for it - add S&H to old europe and it's waaay out of my confortable range. Thanks in advance, Arno

Reading/Verifying the Intel 8041A

by mainpatents＠gmail.com

The Intel AFN-00188B Datasheets for 8041A/8741A specify that EA max is 24.5V. The verify mode for "PROM/ROM" holds EA high at 23V. The 8048/8748 Datasheets say EA is 32V for 8748 Verify but need only be +12V for 8048. Richard

New PDP 11/44 pics, interior card cage

by billdeg＠buzz1.com

I mentioned earlier I had an ebay auction running for an 11/44 and there were questions about the interior card cage. I uploaded new pics. Here is what I could discern from the photos I took of the interior card cage's cards M7856 M7819 M7814 M7258 M7258 M7258 M7297 / M7298 M9202 M7295 ?? ?? M7819 When I posted the original listing I assumed incorrectly that all of the computer cards were in the 11/44 and the internal cage was for the few backup tape drive interface connectors. Apparently I was way off. The new pics help explain what the 11/44 was doing before being taken out of service.. Ebay: 271869650084 (ends later today) new pics: vintagecomputer.net/digital/PDP11-44_2nd/

More stuff that can't be shipped

by jnc＠mercury.lcs.mit.edu

> From: Cindy Croxton > Piles of OLD DEC stuff Like what? Like most people on this list, I'm far enough away that I can't just drive over (especially on such little notice), but if there's something good there, perhaps a local DEC collector can help, or I could pay someone to go get it. But without having _some_ idea what's there.... Any cables? (Those seem to usually be in short supply.) Any chance of some pictures, if you have no idea what's what? Noel

Interactive Baseball/Don Daglow

by cclist＠sydex.com

WikiP under the "PDP-10" subject claims that Don Daglow wrote the first computer baseball game in 1971. I don't think that this is accurate; do any old CDC-ers out there remember the BAT PP program on every CE's MACE deadstart tape? I believe that it preceded Daglow's game by a couple of years. I know this may chafe some of the DECfans out there, but I think the claim is simply not accurate. --Chuck
