Almost all DL11-Ws have the RS232 driver/receiver chips on them, and if you've got one of the few that haven't. it's not hard to add them (1488 and 1489 IIRC). It's also not hard to make up the RS232 cable. I've done it many times. Let me know if you want to do this and need pinouts, etc. I don't know what test gear you have, but if you have a logic probe, then you could monitor the TX output of the UART (I assume you have the printset). It should blip low (actually a fairly complex pulse train if you have a logic analyser) when it's doing the register printout. That would at least tell you if the unit was working at all. -tony --__--__-- Message: 10 From: "Jonathan Engdahl" <j.r.engdahl_at_safeaccess.com> To: <cctalk_at_classiccmp.org> Subject: Free Scanning Electron Microscope Date: Sat, 8 Mar 2003 21:43:57 -0500 Organization: Rockwell Automation Reply-To: cctech_at_classiccmp.org Free scanning electron microscope to whoever wants to 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 anything 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 (vacuum pump?) - 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).

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.

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.

Any help appreciated. Rich, the terminator sounds right. One that I have differs only in a -1- vice your -3-. It is in position 2F nearest to the card edge connector.

Are these actual computers or just dumb terminals with a telephone built-in? I have a Northern Telecom unit like this. It's a smaller terminal with a phone handset and keypad on the base.

They're real 68008 computers, based on the Sinclair QL design. The power supply (in the screen) is always on, at least in part, and the computer can be set up to auto-answer. The application software in ROM is all communication-centred, with things like dialling directories and (I think) a terminal emulator.

Hmm... I must remember to try and find a silicon wafer on Ebay... Shame there never seem to be any on Ebay UK... Let's see... If I put the wafer under a microscope and get some photos, I should be able to ID the chip. Then put it in a picture frame complete with label... Hmm...

I think the only wafer's I've seen out in the wild are some wafers from Tektronix. Back in the 70's when I was in school someone from Tektronix visited us, and everyone got a wafer in a little plastic wafer holder.

Have you considered repairing the one you've got? Possibly, but I've absolutely no idea where to start... I'm guessing that the fault is somewhere in the telephone side, as the computer side works just fine. Also, it's capable of taking incoming calls (shame CLID didn't exist when the OPD was around), and if something else dials, it can latch into outgoing calls without any problems.

I'm not really sure. It's entirely possible that there's very little to no difference between the modules, but the UK versions would have had to pass the extraordinarily strict BABT approval process - which was very expensive, and essential if you wanted your kit to be "BABT approved" and therefore legal to use on the UK 'phone system. Also, there was some fairly hefty licencing restrictions, e.g. in the front of the OPD manual it states the functions it's been licenced for. >I have a number of these things -both complete and working, as well as >partly ratted for spares (including some telephony modules)- they were >called 'computerphones' down here. I'd be willing to try an NZ module, if it's got standard BT-like connector jacks on the back of it (same type as used by Sinclair on the QL - did he get a job-lot of sockets to go with the OPD plugs, I wonder?). I know bugger all about the NZ 'phone system, but as my NZ cousin is currently over here, I'll ask him tomorrow. > About the only useful function they had >was the phone directory/dialler which was a winner. Definitely; the 3-alphanumeric "short code" is also a staggeringly useful thing. In fact, I've decided to use the OPD as my main telephone, if I can get a reliable telephony module for it. > They were just a year >or so too late to ever really catch on in the face of competition from Macs >and pcs for any serious desktop computer functionality.

Your question is already answered, but what the heck... The ICL OPD (One-Per-Desk) and Merlin Tonto (identical machines internally) were a derivative of the Sinclair QL, featuring the addition of a telephone handset, better keyboard, slightly improved microdrives (sufficiently improved that they are, apparently, incompatible with QL mdvs; something I've not checked yet), and a much bigger ROM. That ROM contains a telephone directory, and a few other utilities to boot. Add-on ROMs included messaging (I'm unsure as to what that is yet, although mine has it), Psion Xchange (Quill word processor, Easel graphics - well, graphs, Archive database and Abacus spreadsheet). Xchange also featured on the CST Thor[1], and was also ported to the PC, IIRC. The QL suffered along with the original separate packages until its demise. My OPD also has a 3rd-party addon disk interface (which plugs into the ROM pack), which is rather nifty, and a lot more reliable (and faster) than microdrives. The machine itself, however, is quite painfully slow. I'm not entirely sure what they did to it to make it that slow; the QL seems to trot along much more quickly. Maybe ICL just didn't write decent software... [1] BTW, does anyone have a CST Thor (especially if you're willing to part with it). Any make/model considered, working or not. I'll even pay cash[2] for it. I'd /love/ to get my hands on one! [2] What's more, I'll even pay more than 75p[3] & a packet of Rolos! [3] or 85p, counting inflation. -- Cheers, Ade.

Yep, a loadable telephone directory (so you could have different ones on different MDVs), two terminal types (a Prestel & "glass teletype") which would operate over the built-in modem - capable of a whopping 1200bps or 600bps half-duplex, and 300bps full duplex; also capable of a 75bps "back channel" at 1200/600 speeds. >Due to UK telecom regulations at the time of release, it wasn't >able to act as a telephone answering machine, though.

It does have a really nasty voice synthesizer built into it, though, so it will take a call unattended, and play the pre-recorded messages. It lacks the ability to say things like "Good morning" though... I think it's also limited to a single auto-answer setting, which can be set to automatically come on between certain times, and (possibly) overridden.

Or maybe I'll sell some of it on eBay and use those proceeds to buy a scope on eBay.

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. As the cost in money, time, and effort goes up, either my interest wanes or I start wanting some return. -Frank McConnell --__--__-- Message: 50 Date: Sun, 9 Mar 2003 20:01:08 -0800 (PDT) From: Brian Chase <vaxzilla_at_jarai.org> To: cctalk_at_classiccmp.org Subject: Re: Collecting silicon wafers Reply-To: cctech_at_classiccmp.org On Sun, 9 Mar 2003, Steve Jones wrote: > Dave Wilson writes: > > My interest is in collecting whole, undiced silicon wafers.

The San Jose Tech Museum's gift shop has them for sale at prices that won't break you too badly. IIRC, it was somewhere in the $10-$30 range, depending on their sizes. It looks like they're available for sale online: <http://store.thetech.org/slicofsilval.html> Of course, you can't get to pick and choose them like you would if you were actually there. When I last visited, they had a variety of wafers available. -brian. --__--__-- Message: 51 From: "Keys" <jrkeys_at_concentric.net> To: <cctalk_at_classiccmp.org> Subject: Re: Collecting silicon wafers Date: Sun, 9 Mar 2003 22:26:23 -0600 Reply-To: cctech_at_classiccmp.org Keep checking eBay for them as I picked up several there for good prices. ----- Original Message ----- From: "Brian Chase" <vaxzilla_at_jarai.org> To: <cctalk_at_classiccmp.org> Sent: Sunday, March 09, 2003 10:01 PM Subject: Re: Collecting silicon wafers > On Sun, 9 Mar 2003, Steve Jones wrote: > > Dave Wilson writes: > > > > My interest is in collecting whole, undiced silicon wafers.
