Has anyone dissected one of the blue Iomega 25-way cables that are marked "AutoDetect" at the female connector end? I've got one in the junk pile and on a meter it checks out as though it's wired with a 1:1 pin mapping, but I assume the "AutoDetect" label means that it has some kind of smarts embedded into one end or the other (or both) which only work their magic under certain conditions. I'm on the hunt for a DB25 male connector and bit of multi-way cable so I can wire up a null modem cable for the QX-10 [1] - if it's all at the female end then that's good because I'd be lopping that end off anyway... [1] which has a DB25 female RS232 port, and of course the only gender-changers I have here are DE9s, no DB25's... :-) cheers Jules

I also didn't like the ADM3A because of its screen clearing difficulties. However, I preferred using the ADM5s as I found them subjectively faster than the VT100s (even after making sure smooth scroll was disabled). I never did any objective testing but I put this down to the longer and more complex escape sequences used by the VT100, especially when connecting to something that did a lot of cursor positioning. As far as I recall, all would have been set to 4800 baud. Regards, Peter Coghlan.

Odd TTL chip

by wdonzelli＠gmail.com

I have here an odd 7400 TTL chip - the prefix is TG. TG74S00J. Who was this? Who made TG74xx TTL? It looks somewhat like an old Sylvania ceramic DIP from the early 1970s. I have perhaps thought Transitron, but it is not. And there is no logo, other than a plain looking T. Ideas? -- Will

Top posting makes a lot of sense for people who want to read the gist of what is being said now, instead of having to scroll. Personally, I do both. But I don't mind the flame bait for people who won't or can't see both sides of the issue. A good point was made about voice synthesizers and top posting in another post. I tend to equate sending messages to back in the 30 baud days ... less is better unless needed for clarification. And never let it be said I won't fan the flames ... especially when I have a few minutes to spare :).

Don't need Kermit anymore (update)

by xmechanic＠landcomp.net

Just a quick update to let you guys know I finally got Kermit80 up and running. Found MLOAD.COM and got it transferred over and used it to link the kermit hex file and the Xerox 820 overlay. Played with it a bit last night and hooked an old Hayes 14400 modem up to the comm port and although I can set the command string(s) for the modem, it doesn't hand control back to the terminal after it connects (was trying to get it to connect to an old 80286 that has my TRI-BBS software on it) I'll probably have to stick with transferring stuff back and forth with Tera-term or something similar. There's kind of a grey area with Kermit on just how much control it has over the machine's comm port (varies from one machine to another), so maybe I'm trying to run data through it faster than what the port will allow. I need to get with Chuck Guzis at some point and get a license for 22disk, just not right this minute, until I get this months bills caught up. :P Thank you Chuck, and everyone else for your help.

Don't need Kermit anymore. :)

by xmechanic＠landcomp.net

You guys are going to get a good laugh out of this... I got desperate and did a little measuring and eyeballing on the index sensors on my 8" drive, and then took one of my prized DSDD Fujifilm guaranteed 100% error-free disks, and carefully opened it up and even more carefully slid the disk out onto a clean sheet of paper. I then took a 1/4" drill bit and heated the back side till it was almost red hot and shoved it through the jacket around where the other sensor was located. Cleaned up the excess plastic with a razor blade and smoothed everything up and carefully re-inserted the disk. Covered up the other sensor hole and tried it out. Oops! Hole was about 3/16" too low. Carefully slide the disk back out and notched the hole out a bit. Re-assemble disk and tried it again. Ahaa! Drive now sees disc. Formatted with 22disk using the XER5 SSDD setting and wrote 2 hex files to it. Shut down PC, hooked everything back up, and miracle of miracles, the Xerox actually read the files and let me copy them to the hard disk!! Now all I need to do is get MLOAD.COM loaded on it so I can combine the 2 hex files (kermit & the Xerox overlay) and theoretically, it should load and run. But it's been a very long day, and I just now found MLOAD on my Walnut Creek CD, so something to do tomorrow. So, the theory is correct, the 2 sensors DO designate between single & double sided disks... (for future reference) :-) Dave Land Land (vintage) Computer Service :-D

DECnet on SIMH/VMS 3.7

I am trying to get DECnet working on SIMH running VMS 3.7 using a DELUA.

pdp11/34 strange problem indeed.

by roe＠liveblockauctions.com

I'm restoring a pdp11/34a, and I've got a weird problem I'm hoping someone out there can help me with. The system seems to be working just fine, with one exception: bus reset just doesn't work. The unibus is configured correctly; I've verified that NPR is jumpered/granted correctly through the bus. This is a BA11-L box with the DD11-PK 9-slot backplane, configured like this: Slot 1 - CPU Slot 2 - CPU Slot 3 - A/B M9312 bootstrap/terminator, C/D/E/F M7859 front panel programmers interface controller Slot 4 - 128 Kword MOS memory Slot 5 - RL11 controller Slot 6 - C/D/E/F M7856 DL11-W console RS232 interface Slot 7 - C/D G7273 dual bus grant Slot 8 - C/D G7273 dual bus grant Slot 9 - A/B M9302 terminator, C/D/E/F M7856 DL11-W configured at 776500 for TU58 tape drive The symptoms: At poweron, the system starts the M9312 console emulator software; I can use it to deposit a small program into memory with no problem. Attempting to use the "S" command to actually start the program causes the RUN light to come on; the program never executes, hitting CTRL/HALT on the front panel causes BUS ERR, the RUN light stays on, and the only way to regain control of the system is power off. For example: @ L 1000 @ D 000777 @ L 1000 @ S fails as described above. If I use the front panel to install a program and run it, when I push CTRL/START, the system halts at the start address. For example: CTRL/HALT CLR 1000 LAD CLR 777 DEP CLR 1000 LAD CTRL/START the system halts, run light out, at address 1000. If I then press CTRL/CONT, the RUN and SR DISP lights come on, and everything works perfectly. I can CTRL/HALT the system, continue, etc. With no problem. Furthermore, if the program I enter contains a RESET instruction (000005), the behavior of the system as it executes that instruction is pretty much exactly like using the "S" command from the console emulator - RUN stays on, CTRL/HALT causes BUS ERR, and the system is non-responsive until I power the beast off. For example: CTRL/HALT CLR 1000 LAD CLR 240 DEP DEP DEP CLR 5 DEP CLR 1000 LAD CTRL/START (the system halts at address 1000) CTRL/HALT (single steps to location 1002 correctly) CTRL/HALT (single steps to location 1004 correctly) CTRL/HALT (single steps to location 1006 correctly) CTRL/HALT (RUN light comes on, CTRL/HALT causes BUS ERR with RUN, system is no longer responsive, have to poweroff) My reading of the unibus tech manuals indicates that there is no ACK of any kind for BUS INIT, so I am somewhat confused. There _is_ a bit of noise on the +5V power supply; a voltmeter shows 5.02 volts stable, but there is a .5V spike at 50 kHz showing on the scope; I can't see this causing problems _only_ with BUS RESET. I have also verified that CTRL/INIT from the front panel seems to do nothing at all. For example, if I halt the system and press a key on the console emulator, examining 777560 shows 000200 (which is correct, there is a character available at 777562). Pressing CTRL/INIT on the front panel does _not_ clear 777560 - it still shows 000200. All the 11/34a M9312 diagnostics run fine. This problem seems to be limited to attempts at RESET. A disassembly of the M9312 console emulator code shows that two things happen when you use the "S" command: 000005 (RESET) followed by a JMP (R5) It's the RESET that drives the machine nuts.

FS. Working PDP 11/83 deskside case (UK)

by silvercreekvalley＠yahoo.com

Hi, I have a working PDP 11/83 in a Pedestal (desk side) type case. Its fitted with a reasonable sized Hard Drive, tape drive and 5.25" floppy disk. I think it has ethernet, but need to check. This is in good shape, and boots. Its the larger desk side case (not sure on the case name) so there is room for a second hard drive. These are nice, 'office friendly' versions of the PDP 11, and quite a bit easier than the UNIBUS machines to manage. Email me if interested. I can get full specs and pictures if there is any interest. Thanks Ian.
