Interlnk (was RE: New bounties ($$$) )

by Robert_Feldman＠jdedwards.com

No, should work with either serial (3-wire or 7-wire null-modem cable) or parallel (bidirectional cable). However, for intersvr /rcopy, if you are using any port other than COM1 on the _destination_ computer, make sure you are _not_ running SHARE on that computer. -----Original Message----- From: Chad Fernandez [mailto:fernande@internet1.net] Sent: Monday, March 10, 2003 9:06 AM To: cctalk(a)classiccmp.org Subject: Re: Interlnk (was RE: New bounties ($$$) ) Feldman, Robert wrote: > 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!). > > On the _server_ computer, at the command prompt, type: > > intersvr<cr> > > Intersvr can also pump the needed files to a second computer using: > > intersvr /rcopy<cr> Doesn't that have a restriction of being only with a serial connection? I don't think that works with parallel. Chad Fernandez Michigan, USA

Power pinouts for Compaq SLT286?

by Robert_Feldman＠jdedwards.com

I'm not sure you understood my question. I was asking about pin 4 the power transformer pinout, not the battery. Using the information you provided, though, I opened up my SLT over the weekend and pulled out the power supply unit. Looks like the middle two of the battery contacts are for charging, as the one on the left is ground and the one on the right goes directly to a small fuse. Pinouts on the power supply connector are harder to trace (especially with the limited equipment I have). So, anyway, I put 12V into the contacts in the unit where the battery fits and turned on the switch. The keyboard LEDs went on for a second, then off -- no beeps or other sounds. A little more investigation revealed that the LED Indicator board is missing. It fits in the memory shield and plugs in at the front of the motherboard. From what little it says and shows in the Maintenance and Service Guide pdf (amazingly available on the Compaq web site!), the LED Indicator board just has LEDs, so it shouldn't be too hard to duplicate or work around, but it would be nice to get a scan of both sides of that board (hint hint :) ).

I charged the batt up, and now 2 & 3 show 12.9v, and 4 shows 13.9v, so there's some tolerances for you.

I wonder what happened to the Enigma machine?? Good point; although as that Boat was sunk, I suspect the enigma was destroyed either by the crew, or by spending 40-odd years under water. I've heard that they're going to preserve it as-is (i.e. in it's rusty wrecked state), which I think is a shame; it'd be interesting to see it restored IMHO. One of these days, I really must get around to visiting the historic ships...

Interlnk (was RE: New bounties ($$$) )

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!). On the _server_ computer, at the command prompt, type: intersvr<cr> Intersvr can also pump the needed files to a second computer using: intersvr /rcopy<cr> -----Original Message----- From: vance(a)neurotica.com [mailto:vance@neurotica.com] Sent: Saturday, March 08, 2003 2:56 AM To: Doc Shipley Cc: cctalk(a)classiccmp.org Subject: RE: New bounties ($$$) <snip> I'm pretty sure it's INTERLNK that runs in CONFIG.SYS and INTERSVR runs on command-line.

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.

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.
