Correct. On the _client_ computer, add the following line to CONFIG.SYS: device=c:\dos\interlnk.exe (if interlnkexe is in C:\Dos, of course!).

PDP-11/34 Progress Report

by jss＠subatomix.com

I've made some progress with my PDP-11/34. Since last week's PSU corn-fusion, I pulled all the cards, air-dusted them, air-dusted and inspected the backplanes, took an inventory of jumper and DIP switch settings, put a minimal CPU+mem+console card set in, connected the backplanes to the PSU, and turned on the machine. It was a little more complicated than that, but I've got what seems to be a working 11/34 in my living room. Learned: As I had mentioned previously, my M9312 had a strange start address dialed into its DIP switches by one of the previous owners. That has to be a mistake. When the machine boots, it immediately halts. If I manually start the processor at the correct address for the console emulator, I get a steady run light. I do not have a console terminal attached yet. Learned: A previous owner had a rocker-style DIP switch block on the console DL11-W set backwards (i.e. one's complement of the correct setting). The DL11-W was being configured with the wrong interrupt vector. Learned: If you plug in a G727A bus grant card backwards, the processor will not halt. :-) To do: My only existing cable that plugs into a DL11-W is for 20mA current loop. I have a current loop VT52 that I haven't yet tested. I'll see if I can do that tomorrow. After all, it would be nice to know if the register printout is actually occurring. It's so late it's early; therefore, I should go to bed. Tomorrow I'll run some test programs! -- Jeffrey Sharp

HP1000 - Update

by avickers＠solutionengineers.com

Well, good news & bad news from the weekend regarding the HP1000's. First, the good news: I've confirmed that both CPUs are in working order, and they both have 4 bootloader ROMs. Testing went little further than this, because: a) I couldn't make it read from the disk, either because the interconnect is wrong, or I'd got my MAC address wrong, or hadn't done something required by the bootloader ROM, or don't have a disk bootloader. I tried all four ROMs, but no visible life from the disk. 'course, not having a terminal to plug in didn't help... b) The bad news - both 'A' and 'B' machine cabinet PSUs failed (with a distinct smell of Magic White Smoke about them), causing the supply ELCB to trip. I'm unsure as to whether it's the fan, or the PSU which caused the problem (the fan sounded pretty bad). The individual internal components (CPU, mem extender, etc.) are all fine, so surgery will be simple. However, I suspect the cause is damp, so I'm not going to fix & power up again until summer and/or I get the paraffin heater working again. And now, the s/w which came with the machine. All of this is on 1600bpi tape: KEY: Format of tape in square brackets, where none, either unknown or I forgot to write it down p/n = part number R. = Rev.

Free Computers in St. Louis: PCjr, Apple IIGS and more

by nickmiller＠charter.net

I've finally come to realization that I do not need 2 (or more) of every computer I can latch on to. I have a complete IBM PCjr system with monitor and keyboard and several Apple IIGS systems all with keyboard, monitor and floppy drive. I also have some CoCo 2's, TI-99/4A's, some ugly Amiga 1000's and some C-64's. I realize these are aren't the rarest of computers but they are still fun to tinker with and the price is right. These are free for pickup only, I will not ship them. If you're passing through the St. Louis area on I-70 in St. Charles drop me a line and we can arrange a meeting. If you are able to stop by and feel like geeking out I have 300ish computers in the basement including an Atari 1400XL with 1090XL box, Altair 8800, IMSAI 8080, PET 2001 and others that you might like to check out.

Info on Dataspeed's products

by apteconsulting＠attglobal.net

Happened to find this thread while searching for old colleagues; thought I would send you some info. I worked as an R&D Engineer at Dataspeed from during 1983-85, and was the principal developer of the Modio software. I left when Lotus purchased Dataspeed, and sadly, my stock options became worthless. With regards to the thread (included below), we were using the sideband on the PBS FM stations. At the time I left, we were airing stock, commodities, and futures data during "market hours", and sports during off-hours. The service was by subscription, and there was a hash algorithm which used the unit's serial number and the subscriber account number to generate the flags which activated various services. If memory serves, the flags were "splattered" across the memory map, e.g. bits in different locations together formed the service byte for a service. Lost contact with the other engineers and staff. One engineer is installing Internet in churches in Korea; one of the co-founders owned a sports bar in Pacifica, CA. But all this is old info. I still do have a framed Quotrek on my office wall ! Pass on this info as you deem fit. Gary Apte It's my understanding (infamously unreliable) that Lotus Signal was descended from DataSpeed's Modio which was descended from DataSpeed's Quotrek which dates back as far as 1981. - Jim Jim Keohane, Multi-Platforms, Inc.

Collecting silicon wafers

by classiccmp＠crash.com

Dave Wilson writes: . > My interest is in collecting whole, undiced silicon wafers. These > are much more accessible for research and the interest does not > conflict with those of other people. I think they're interesting, and have considered picking some up when I've seen them. Of course I've only seen them on eBay, and living near Boston I guess my only local source might conceivably be the DEC fab out in (I think) Hudson that got sold to Intel when Palmer gutted the company. Oops, didn't mean to start that thread again! ;^) > Are there other interested people out there? If this site is not > the best for this sort of discussion can you recommend a better > one? I haven't run across anyone systematically collecting wafers. The main question I'd have is, where's the supply? If there's not a large supply of available wafers, how many collectors can there be? Having opened my mouth and said that, someone will probably tell me that fab-rich places in Arizona, California, Oregon, and Texas are using them as wall decorations or something...

Y'all should have spoken up sooner and I might have tried to pick some up for you. Seriously, educate me/us. What's interesting, what would need to be done to care for it through shipping, and what's it worth to you (and I appreciate that the answer to this may not be financial in nature, and it need not be so on my side either!)? More seriously, inexpensive items (say US$1 and under) that don't require a lot of effort on my part can pass easily from my hands to someone else's, and I'm happy to help, especially if it'll help get an interesting story out there to for other folks to enjoy and learn from.

New To List and PDP8 Question

by bkotaska＠earthlink.net

Hello, I am new to this group but have been reading the posts occasionally before finally joining. The site comes up alot when searching for info on old machines. I am interested in any type of old computer especially the single board trainer types from the early days of the microprocessors. I have built my own trainer based on the Intel 4004/4040 and have started to put a web site together with pics and info. It is in the early stages though - http://home.earthlink.net/~bkotaska/mcs4_micro.htm . I have also started to build a PDP8 clone from the Harris/Intersil uPs. Still need to gen up a front panel for this one. A computer is just not a computer without some kind of built-in feedback mechanism. (I guess it just makes you feel like you are in control of the machine instead of the other way around.) Building the PDP8 has really piqued my interest in the real thing. I've collected bits and pieces for awhile now and have finally obtained a 4K core stack - although it is not in great shape (any help in locating a better one would be greatly appreciated). Anyway my question to you PDP8 folks out there is this - I have the following pieces: front panel, M8300, M8310, M8320, M8330, M837, M8650, G104, G227. I also have a 20 slot omnibus backplane from a PDP8a. My guess is that I should be able to see some action on the front panel with just the first four modules present (i.e. no memory). Am I correct? I don't care at first if I can't read or write to memory. I just want to check out some of the control functions with as little hardware as possible. By the way, my front panel has mostly light blue and dark blue switch handles. Anyone seen this before? Thanks all, Bill

Free Scanning Electron Microscope

by j.r.engdahl＠adelphia.net

Free scanning electron microscope to whoever will come haul it away. It was left by the previous occupant of my lab, and it's blocking the hallway. I want it out of there. There are four main pieces, plus some parts and manuals in boxes. I don't know much about this, but I will describe it's appearance: - microscope unit - desk high box with precision stainless steel tower, shoulder high - ISI Robinson detector mounted on side - Perkin Elmer gizmo mounted up high - other probes and sample holders sticking out at odd angles - very rocket science - no other name plates visible without moving a lot of stuff - viewing station and analog controls console - name plate: ISI WB-6 - built-in CRT - lots of knobs and buttons - very mission control - Tracor Northern computer - floor standing console a little larger than an ASR-33 - two 5" floppies - card cage inside - Intel 8080 microprocessor - keyboard - no hard drive, don't think it ever had one - separate RGB CRT - a 2' box with lots of wires and tubes coming out of it - a 3~4 gallon tank that looks like it bolts on the side of the tower - a small rack with instrumentation modules in it The date plate on the back of the viewing console says 1985. It was used by our semiconductor quality control department to look at the insides of integrated circuits. Rumor has it that there is a vacuum leak in this somewhere, it probably needs a new gasket. It is already uninstalled and ready to roll away. I found a web page with a picture of a similar unit. Our machine has an very similar viewing console, but we have more stuff mounted on the microscope itself. http://www.optics.arizona.edu/Milster/Labdescriptions/Misc.htm ***NOTE*** This thing has a radiation sign on it (X-rays). Transportation and use is regulated by the Ohio Dept. of Health, Division of Radiology. I understand you need to get a permit to move or operate it. If you are really interested in this, you need to know how to get the required permits. If you are interested I can take some pictures and send them. -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 1 Allen-Bradley Drive Advanced Technology Mayfield Heights, OH 44124 http://users.safeaccess.com/engdahl j.r.engdahl(a)adelphia.net

Collecting siilicn wafers

by davol＠globalnet.co.uk

I noted some time back that chip collectors are not highly regarded on this site - on the grounds that they are prepard to 'mine' perfectly functioning boards in pursuit of their interest. My interest is in collecting whole, undiced silicon wafers. These are much more accessible for research and the interest does not conflict with those of other people. Are there other interested people out there? If this site is not the best for this sort of discussion can you recommend a better one? Dave
