HP 9000/380 console? software? (was Re: HP 9000/382 Questions)

by spacewar＠gmail.com

I've borrowed an HP 9000/380 from a friend, along with a 9122D floppy drive, but no software. It has an A1416A Color VRX DIO-II "Kathmandu" video interface, but I'm hoping that I can just use the serial port as a console. Does the DE9 serial console use the IBM pinout? Do I have to pull the A1416A to get it to use the serial port as the console? Is there any software that can be booted on it from the floppy, such as perhaps non-HP-UX BASIC?

BC11A paddle boards

by ggs＠shiresoft.com

I just received the first of the BC11A paddle boards (so that I can now create my own BC11A cables). I made two variants of the boards. One where the cables come out the ?top? and another where the cables come out the ?side? (so you don?t have to ?fold? the cable in a number of different applications such as RK05s). The ones that arrived today are the S or ?side? variation (as opposed to the T or ?top? variation). I immediately noticed (why I didn?t see this when I was reviewing the board layout previously I?ll never know) is that one of the cable connectors is too close to the edge. It wouldn?t be a problem except that I chose to use connectors that have cable retention latches. The latches protrude from the board edge by ~0.02?. So once I verify that these work, I?ll move the one connector inward ~0.5?. I have plenty of space, I just don?t know why I put the connector that close to the edge. *sigh*. For these boards, I?ll probably just file the latch down a bit to get the appropriate clearance. BTW, trying to get the connectors onto the board (I haven?t soldered them in yet) was tight. That?s the problem with trying to get 60 pins to all line up correctly. But they fit and are *snug*. I probably won?t go and do any testing until I get the other boards in so it may be a couple more weeks (the boards weren?t supposed to *ship* before 2/8). For those who?d like to know, I probably will not be making a production run of these boards unless I get a *lot* of interest (100 boards or so). If you want some, let me know and if I get enough interest, I?ll do a production run. TTFN - Guy

That should be fine; the DEC M9042 board (basically equivalent) used three H854 flat cables, see: http://www.computerhistory.org/collections/catalog/XD149.80 The DEC board makes every other conductor in the flat cable a ground; not quite as good as twisted pair, but close. > I probably will not be making a production run of these boards unless I > get a *lot* of interest (100 boards or so).

Mitsubishi Apricot

by pchatt30＠gmail.com

Hi all, Dose anybody know about Mitsubishi Apricots (1990ish)? They are of interest to me as they were the first PC I used and I now have a few. I'm having issues with getting them to boot from a floppy. Iv done some reading around the subject and from what I understand I need a secure boot floppy. Can anybody help? Thanks Peter

DEC TS05 mains switch

by ard＠p850ug1.demon.co.uk

As I mentioned some time back, I am currently restoring a VAX 11/730 system. It is the version with the TS05 on the top, I currently have the TS05 in many bits while I sort out at least 4 faults with it (No, I've not sorted out the TU58 console tape drive yet, I needed something else to get on with while I was thinking about that). One problem with the TS05 (Rebadged Cipher F880E, of course) is the mains switch. Only one pole (double pole switch) opens, and it gave quite a nasty spark when I put mans on the unit. So I want to replace it. The problem is that I have never seen one like it before. It has _5_ terminals. Four of them are what you'd expect for a double pole on/off switch, The other is for the built-in neon indicator. Rather than just wiring it across the output side of the switch (as most do), this unit has a neon with the correct series resistor for 115V operation wired between one of the output side terminals and the fifth terminal. The TS05 puts the neon in parallel with the supply for the 115V blower unit. Thus the power on indicator gets 115V no matter how the voltage selector is set. The switch is the stadard size for double pole rocker switches (30mm * 22mm panel cutout, isn't it?). If I can't get the right replacement I have several options : 1) Fit a normal 230V illuminated rocker swtich, and asssume I will never change the voltage selector setting (but I am trying to keep this machine electrically original). 2) Fit a normal non-illuminated rocker switch. It will then be OK on any mains voltage, but no power-on indicator, and it's not electrically original 3) Fit a non-illuminated rocker switch and find a place to fit a separate neon indicator. It is then electrically original, but won't look right 4) Try to mend the original switch 5) Try to make an equivalent using bits of switches I can get. Does anyone have any ideas where to get the original switch from? -tony

V05.06 RT-11 DOC Set - Pickup Required in Los Angeles to Help Jay West

by jhfinedp3k＠compsys.to

V05.06 RT-11 DOC Set - Pickup Required in Los Angeles to Help Jay West An old RT-11 fellow tried to sell his V05..06 RT-11 DOC set on eBay, but no one bid. Jay West has expressed a desire to have the hard copy set of manuals. Is there anyone in the Los Angeles area who would be willing to pickup the manuals (there are 14 in all) and either keep them until there is a pickup of else ship them? I hope we can help out Jay for all the effort over the many years!!!!!!!!!! Jerome Fine

Terminal Emulation for Windows - supporting Kermit File Transfer

by radiotest＠juno.com

I still use a computer with Windows 98 SE and a native serial port for terminal emulation. The program that I use is not free but it does more varieties of terminal emulation, and does them better than any other emulator that I have used - ProComm Plus. I have owned it for about twenty years. Dale H. Cook, Roanoke/Lynchburg, VA Osborne 1 / Kaypro 4-84 / Kaypro 1 / Amstrad PPC-640 http://plymouthcolony.net/starcity/radios/index.html

Terminal Emulation for Windows - supporting Kermit File

by Martin.Hepperle＠MH-AeroTools.de

> Is there free-for-use Kermit alternative around to be used for > Windows or another Terminal Emulation which supports Kermit > File Transfers "out of the box"? > > Yes - I know Kermit 95, but this is not free. > As Rik said, TeraTerm is very useful and also offers Tektronix emulation, ASCII up- and download and much more. If you search for k95.exe you fill find some ftp and web sites which also have executables of Kermit 95. You can also run MSDOS-Kermit in a Virtual Machine if you like. Finally, I think you can also use the HyperTerm program from Windows XP on later Windows versions. Nartin
