I'm pretty sure that I have a complete set of 11/730 TU58 tapes in my storage unit. I might even have some brand new tapes. If I can find them, I would be happy to send them to you. They have been sitting in storage for probably 20 years, so there are no guarantee that they are readable. I'm cleaning out the storage unit right now, in preparation for moving, so I'll keep an eye out for them. Alan "Pack rat" Frisbie

Logic Analyzer software for the HP-IB/RS-232 bus pre-processor HP 10342B

by marc.verdiell＠gmail.com

This has probably been asked before, but does anyone have the software package that came with the HP-IB/RS232 HP10342 bus pre-processor for the HP1650 series Logic Analyzer (actually I have a 1670G)? It should have a config file and an inverse assembler file. I'm interested in the HP-IB files. Can't find it anywhere. - Marc

M68020-PGA to M68EC020-PGA

by carlojpisani＠gmail.com

hi I am playing with an old Motorola board and I have a problem As you well know, the 68020 is a 32-bit microprocessor from Motorola, released in 1984. Motorola also manufactured MC68EC020 - embedded version of the MC68020 CPU, housed in different packages than the Motorola 68020 microprocessor, but even in the case of PGA package of 114-pin PGA, MC68020/PGA is not pin-to-pin compatible with M68EC020/PGA They both use 114-pin PGA package, but some pins are different, (Vcc and gnd are placed differenly in the pinout), and you need an adapter! My board's socket is designed for M68EC020, but I need to use a M68020 chip because only the goldcap version, i.e. MC68020RC33 114-pin ceramic PGA, is available at 33Mhz. Code: Select allCPU: MC68020 114-pin PGA ----[adapter] ---> socket: MC68EC020 114-pin PGA Do you happen to know *where* I can find an adaptor M68020-PGA to M68EC020 PGA? Do you happen to have for sale? here I am Thanks!

Fairchild 9440/445 MicroFlame?

by bob＠jfcl.com

I'm looking for manual scans, software, really any documentation of any kind for the Fairchild F9440 or 9445 (aka the MicroFlame) microprocessors. Yes, bitsavers and a few other places have datasheets for the chips, but that's really about all the documentation I've found. And yes, I know that they're Nova clones and can run DG software, but Fairchild had their own development tools too that seem to have disappeared completely. In particular, Fairchild had a single board computer for the 9445 called (I think) the PEP-45. It had a built in EPROM monitor called PEPBUG-45. I'd love to find manuals and schematics for that gizmo. Actually I'd be interested in documentation for any systems that used either of the 944x chips. Bob

Or a working copy of GNAT? Needed for IRIX >= 6.5.27 I will for sure sell the Tezro, Maybe I will reconsider the purchase of a tiny Octane. I am more focused on Linux/HPPA and Linux/PPC32, which are used for job tasks. At the moment. I am developing a fast FiberChannel ram-disk for the radio telescope. cheers

M6809E/63C09E databus behavior question

by brain＠jbrain.com

I agree this is very specific, but I thought perhaps someone could help. As I look at the '09 datasheets, I can't tell when the data lines become valid on a write cycle. I ask because I have created a few projects that place themselves between the CPU and the CPU socket (CPLD based). To play nice with a potentially shared address and databus, my code honors the BA and TSC lines on the IC.? If either line is high, as noted in the datasheet, I tristate the address and data lines. Otherwise, the address lines are valid during the entire E cycle. As for data, it depends on the state of the R/W line. If R/W is high, the external databus is connected to the CPU databus during the entire cycle if TSC and BA are both low. If R/W is low, I initially set the external data bus according to this assign statement: assign data_ext = (!r_w & e& !(tsc | ba) ? data_09 : 8'bz); The '09 boots, but certain devices fail to operate.? If I change the assign to: assign data_ext = (!r_w & (e | q) & !(tsc | ba) ? data_09 : 8'bz); or assign data_ext = (!r_w& !(tsc | ba) ? data_09 : 8'bz); The devices begin working. Either of the modified equations works, but I don't know if can safely place data on the external databus during the entire cycle, like the address lines, or if I need to be off the bus for some small portion of the cycle.? I was hoping the datasheets could help, but I am missing the key portion of the timing diagrams. I hope someone can enlighten me.? I have the system working, I just want to make it as good as possible. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

Manual for Data Media Elite 2500 terminal?

by bob＠jfcl.com

Can anyone point me to a technical manual for the DataMedia Elite 2500A terminal? I'm especially interested in documentation on the escape sequences and the special character sets. This was a fairly high end smart terminal from the late 70s or early 80s. Bitsavers has a short manual for the 1500 which I'm guessing to be similar, but the 2500 has some extra features (e.g. insert line/character, delete line/character, etc) that aren't present there. Thanks, Bob Armstrong

by jnc＠mercury.lcs.mit.edu

> From: Dominique Carlier > I just regret this incredible rise in prices for collector machines > that, not so long ago, were languishing in wet sheds Hey, look at the bright side: as a result, they are much less likely to be simply recycled as scrap. I took great pleasure in telling one seller who'd pulled a board-set, and recycled the rest, that the part he'd recycled was worth a lot more than the part he'd saved. Hopefully that kind of news gets around. Noel

It's in Verilog, so perfect for an FPGA devel board; I think it's in his Github repository: https://github.com/dabridgham/QSIC If you go this route, I have that config-file driven uassembler written in portable C (compiles on 3 different systems that I know of) which uses only standard I/O library which you can use for the ucode; it should handle most any uengine design, unless it has something really wierd.

Looking for a VT52 keycap

by web＠loomcom.com

Hello folks, This weekend I picked up a VT52 DECscope terminal from a fellow collector. It's in fantastic shape, apart from being a little dirty and missing the number "6" keycap from the number pad. This is a real long shot, but if you have a permanently broken VT52 terminal you're keeping for parts, could you please let me know? I'd like to buy a "6" key and make this one complete. -Seth -- Seth Morabito web at loomcom.com

DEC RSX-11D and its COBOL compiler?

by johnwallace4＠yahoo.co.uk

[apologies for lack of context, been away from cctalk a long time and insufficient recall of how this cctalk thing works... yet somehow still remember IAS on an 11/70 from the 1980s] Pick an RSX layered product and lots of fundamental stuff would probably be compatible between 11M, 11D, and IAS (and/or 11M+). Find the RSX version and see if IAS is mentioned as supported in the SPD or other documentation. It often was, and even if it wasn't, lots of non-priv stuff would just work. More IAS background from someone (not me) who was there in the IAS development team in DEC Reading: https://www.john-a-harper.com/ias.html "This page is dedicated to the best of the many PDP-11 operating systems - IAS I couldn't find anything else on the Web about IAS? but it deserves better than to fall completely into obscurity. DEC's approach to operating systems for the PDP-11 was anything but disciplined. New ones got invented every time some engineer or marketing person blinked. In the early days, there was a real-time kernel called RSX-11A, designed for memory-resident applications in what we now call embedded processors. Features got added to this rapidly - code bloat is nothing new. By the time it got to RSX-11D it had a complete disk-based file system, a program development environment, and support for every peripheral in the Small Computer Handbook (and there were plenty of them - peripherals on the PDP-11 obeyed the same strategic imperatives as operating systems - see above). At this time, a bright young engineer called Dave Cutler decided that enough was enough, and set out to create a small system that would do the same, which he called RSX-11M. We all know what happened to him - and he no longer even has the excuse of youthful excess. (continues...)" Hth.

Next 'stack' of computers to go, IBM p7's - not classics this time

by pete＠petelancashire.com

This time not so 'classic' My last job was maintaining IBM p7's and eventually p8's. One thing I started was putting together a home setup. But like all the other projects the gear has become redundant to me. The 'stack' consists of 2 each IBM p720's, a CR6 HMC, and a KVM drawer. The p720 do NOT have any hard drives or carriers, but both are available via Ebay. The carrier was used in more than one model, and in the past I've bought carriers with small disks for < $20 each, then found larger disks of various brands. And the rails are missing from the p720's. Google "ibm p720" I can't remember how much RAM, number of CPUs etc but one p720 was 'loaded'. If interested let me know and If anyone knows a good AIX list please let me know I'll try to get a few photo's this weekend. The 'stack' is located in Portland, Oregon. NO PACKING OR SHIPPING, must be local pickup. -pete

Weird Lear-Siegler ADM-3A board

by jnc＠mercury.lcs.mit.edu

> From: Jon Elson > Steve Ciarcia ... made a board using the NS405 called the Term-Mite. I decided I'd do an article about the Term-Mite for the CHWiki; I found Ciarcia's long article about the Term-Mite (in his book, which Google books has); it talks throughout the article about the NS455 - but it also says "[t]he Term-Mite actually uses a NS405 chip which is a specialized version of the generic NS455". So I went to look up the 405 and 455, to see what the difference was between the 405 and the 455. I found a data sheet for a 405, but not one for the 455. Does anyone know where I can find info about the 455 (or, better, yet, know what the difference is between the two - that would save me some leg-work). Thanks (I hope :-)! Noel

Original CAD code in the wild?

HP 9000-236 (9836CU) video cable.

by robert626001＠gmail.com

My latest score is an HP 9836CU (so, color with a 68010 CPU and HP-UX support) with a 98625A disk interface. I got the matching monitor, but I didn't get the video cable. Googling turns up that it's a very proprietary interface, but I could find nothing about the cable. It's a 15 pin D-sub at each end and I'm hoping that it's just straight through, but have been unable to verify that. Does anybody know? Or Is there anybody that has a 9836C or CU and would be willing to examine the video cable, please? Thanks Robert

Original CAD code in the wild?

by rdawson16＠hotmail.com

For a while I have collected bits of legacy CAD, most recently Martin Hepperle sent me what I believe is the last version of Hank Christianson's MOVIE.BYU, a FORTRAN based 3D modeling and animation system. I also have experimented with the original Berkley SPICE, also written in FORTRAN. This weekend, I am reading "the Engineering Design Revolution", a 650 page history of the CAD industry by David Weisberg, who was there and worked for many of the companies in the beginning of the industry, I highly recommend this for anyone interested in CAD: www.cadhistory.net<http://www.cadhistory.net> The Engineering Design Revolution<http://www.cadhistory.net/> www.cadhistory.net The Engineering Design Revolution. The People, Companies and Computer Systems That Changed Forever the Practice of Engineering. By. David E. Weisberg My question is, did any of the source code for these systems, Applicon, Auto-Trol, Calma, ComputerVision, thousands of lines of primarily FORTRAN ever make it out, where we could read and study this original body of mathematical geometry done on computers? I know we are primarily a hardware group here, but where is the interest in the software discussed? Randy

Digital VT420 repair?

by mail＠waldemar-brodkorb.de

Hi, after my Micro PDP11/83 boots up, I like to connect a Digital VT420 to the console port. This worked approx. 10 years ago. Now when I poweron the VT420 I get no message on the screen. The f3 key doesn't give me the configuration menu. Is it broken? Does it have some invalid configuration in NVRAM and can be resetted? I tried changing brightness and contrast, no change. Is it normal that the right LED is always on? See the picture. https://debug.openadk.org/pdp11/vt420.jpg I tried with and without serial connection to another system. Thanks for any advice, Waldemar

Re: I ran across this strange modernistic Data General ...odd computer

by Bruce＠Wild-Hare.com

G'day Zane - Like every other computer system created, the Desktop Generation has its own set of quirks and wonders. It was an interesting evolutionary repackage of the microEclipse processor, but I never saw a customer or user site actually using the Model 10's MS-DOS "compatibility feature". The hardware consisted of modular metal frame chassis with snap-on plastic covers. While great for manufacturing and cost control, the delicate plastic cover retaining tabs were always breaking and the covers would pull away from the chassis or just fall off. Only an annoying cosmetic problem until you find that a "dead man's switch" interlock was maintained by the power supply chassis front cover. Yes, the power supply would always be cut off whenever the plastic cover shifted, vibrated or fell off the chassis. Which happened often. (The cheapest solution was the unintended, creative use of a ball point pen combined with nerd engineering.) Many OEMS delivered DG/RDOS- or AOS-based applications written in ICOBOL or Business BASIC (i.e. NAPA). These were good systems for OEMs who had previously developed software for DG - providing their application was not disk-bound. DG eventually was forced to design and sell a parallel I/O bus option to help improve disk performance... to the confusion of customers previously told of the benefits of a serial I/O bus design. The system was followed by the DG/500, which had a similar hardware functional microEclipse-based design but enclosed in a then-familiar IBM PC AT (desktop) form factor. This was the final unsuccessful attempt to defend the low-end 16-bit Eclipse line from the PC onslaught. ----- Bruce Ray Wild Hare Computer Systems, Inc.

Original CAD code in the wild?

by jnc＠mercury.lcs.mit.edu

> From: Randy Dawson > For a while I have collected bits of legacy CAD > ... > My question is, did any of the source code for these systems > .. ever make it out Well, not quite what you're asking about, I think (it sounds like you're interested in MechE CAD, not EE, even though SPICE was mentioned), but the original Stanford SUDS is still available, I think. > I know we are primarily a hardware group here, but where is the > interest in the software discussed? Is that a plaint ('how come we don't do software'), or a query ('where is software discussed')? If the latter, it tends to be system specific, from what I've seen - e.g. there's 'TUHS' for Unix, "its-hackers" for ITS, etc. Noel

MS11 M8110/M8120 controller card differences

by jnc＠mercury.lcs.mit.edu

> From: Bob Smith > 8110 for MOS memory, and 8120 for bipolar memory is what field guyde > list says. Well, the early bipolar MS11-C (1K boards) used the M8110 during early production (see e.g. DEC-11-HMSAA-D-D, pg. 1-1), and apparently then switched over to the M8120. I've only seen the later MS11-A bipolar (4K boards - dunno why it's in reverse alpha order) associated with the M8120. > I think the there was some change from special select parts and a move > to schottky 74S series around the time of the 45/50 days. I wondered that, but the MS11-C and MS11-A are the same speed (300 nsec); although maybe the M8110 was a bit marginal, and component changes in the M8120 made it more robust? I guess I'll have to do it the hard way, and compare the ICs... :-( > 11/40 was faster than 11/35, but if you changed a wire, they were the > same. I've heard of other manufacturers doing that, but I thought the /35 and /40 were identical, except for the number on the console inlay, and the sales channel? Noel
