Dear Sirs, my father started in the late 60's with BULL machines (tabulatrices imprimantes etc.) Later we had a GAMMA 10 and also the GE415 (wich is still built up in moment). In case you are interested in any spare parts, machines, sheets, documents etc please contact me. But i also like to ask you for your assistance. We bought a BULL PR54 some time ago and want to fix it to a PC. Unfortunately there is no description about the interface (level 6/66). Can you give us any information ? best regards, Felix Hammann Fabrikstrasse 6 67454 Hassloch phone +49 6324 3001 fax +49 6324 58543 sorry i had a wrong email adress to answer back in my mail

kaypro 2 boot disk.

by cb＠mythtech.net

>I need a boot disk for a kaypro 2. A freind gave me >boot disk for the II, but that didn't work. >Also I need a commodore pet for a display at a school, >dead or alive any model. Can the Kaypro 2 disks be copied without a Kaypro 2? I have some Kaypro 2 software, but it is already promised to someone else (just waiting for them to pick it up whenever they are next in the area). If they can safely be dupilcated with a PC, I can run off a copy while waiting (but unless this is a 100% safe thing, I don't want to do it, I don't want to risk screwing up the disks) -chris <http://www.mythtech.net>

Zapping Laptop batteries

by mtapley＠swri.edu

>From: "Lawrence Walker" <lgwalker(a)mts.net> > > Thanks all. There's also a PD program called "deepdran.exe" (deepdrain) >which I can use to exercise the batteries after, if it's successfull. >Worth a try. There's a similar program for the early PowerPC Powerbooks. I had a really bad experience with it in my 3400. I took a couple of dead, drained, and on-the-shelf for years NiMH batteries. Charged one in the powerbook for a while (15 minutes or so) then tried this program on it. Battery ran down, Powerbook made out-of-power noises, turned off. Plugged in and reset, the battery charged up, no problem. (I'm using that battery now). The *other* battery, I figured I now knew what I was doing. I slapped it in, unplugged the powerbook immediately, and let it run down on the drain-dead program. About 10 seconds later, it made a weird buzzing, and went dead. Next time it powered up was after the power supply board got replaced. :-(. Exercise some caution. I don't know what happened - maybe the PS board got fried because the battery voltage went too low too fast? Maybe it was OK until I plugged it back in, at which point it fried trying to charge a too-dead battery too fast? Maybe there's a problem with a PS designed for Li-Ion batteries charging a NiMH battery (though it's supposed to be OK). I don't know, but I'm going to charge the other battery repeatedly in the external charger before I put it into the PB again. - Mark

SIMH software?

Well, having got the Simulated PDP11 running - my next untutored question is: sim> att rl ....filname??? sim> boot rl ....filename??? How does one get an OS loaded on the 'machine?' Cheers John

FA: Data General manuals, HP and Tektronix manuals, core memory, 3-axis acceleromer, Solaris

by rigdonj＠cfl.rr.com

I'm trying to clean out some of the clutter before the holidays and I've put a ton of stuff on e-bay including some core memory, a programmer's panel (both end in an hour. these are from computers that were junked before I found them), DG manuals, HP 9845 manuals, Tektronix programmable calibration generator manual, a 3-axis accelerometer, Solaris manuals, conductivity meter, and two NICE stepper motor drivers including one that's made by NEAT for driving optical stages. <http://cgi6.ebay.com/ws/eBayISAPI.dll?ViewSellersOtherItems&userid=rigdonj> Joe

You _do_ have to get the software images yourself, and install them somewhere. I myself keep "installation media" in the C:\DIST directory, and "disks" in C:\DSK. Everyone has their own system for that, I assume. Images of installation media are available from the archives, see http://simh.trailing-edge.com/ and the PUPS archive for some. --f

Simple C compiler advice?

by jpl15＠panix.com

Okey-dokey. I have now got all the nice SIMH packages stashed neatly away on the Trusty Laptop. Obviously, they must be compiled. In terms of software, I am an appliance operator. I have had very minimal experience with C programming, mostly in the 'hello world' levels of complexity, and that years ago. Therefore, what would recommendations be for a simple, cheap/free, plain old C package that I could use to compile these simulators? I understand the basic idea behind the process, but it's been many years since I compiled anything, save for the tiny Fortran demo program in the RSX11M docs... I am not going to use it for 'real' programming, just to make a PDP-faux-11 on my Wintel Lap-Puter. T I A John

Performa 550 ??

by gene＠ehrich.com

I have a MAC Performa 550 that was working fine before I put it away. I just took it out and hooked it up. When I turned it on there was a quick indication of power and then nothing. Is there any kind of fuse in these machines or is it probably dead. Help
