... John, IIRC some early versions of Ghost had the ability to ghost via a serial port to another machine. Alternatively could you fit a network card(s) and...
My meter worked fine then last week it would power on to show T7 on the display followed by lots of cycling of the relays that goes on forever. I pulled all...
Hi John, What's holding you up on cloning it? You can copy it over to virtually any ide drive, as long as the capacity is greater than the original drive. ...
Here is what I have done a number of times: 1) buy a USB-IDE adapter from geeks.com (cost ~$15, including the power brick). This allows to mount any IDE drive...
Hi, Very interesting idea. I already have an external USB HD I use for backups.. Almost certainly, I could open up that box (just 2 screws) and move the cables...
Hi Chuck, I want the target to be the same type and size as the original w/ HP P/N in case I decide to sell the system some day to avoid license questions. ...
I've not seen your exact problem but the 4261A is natorious for intermittant connections to the power supply series regulator transistors. The power...
Hi John, That's fine, but once you have backed up your data, and have a working (though non ideal) drive on your machine, you can look at fixing the original...
All, I now posses a HP 71210C spec an for the princely sum of nothing, just for hauling it out of the company's offices because the 70001A mainframe has a...
... Yes, but if you feel adventurous enough you can code a small assembly-based handler to talk to the second hard drive. If all you need is software loading,...
... Well, it was warm here today and the drive started up and ran fine for several hours, so I backed up everything onto floppies. It took 18. Crude, but at...
... What's the problem with using that old drive on any contemporary PC, preferably running some unix? You can then easily copy the contents in their entirety...
... John is going about it in a very roundabout way. Simplest solution: use another PC. If not that, then slap good ole multi-IO card in there, which will...
Not sure I understand... You have $60,000 dollars worth of equipment connected to an old 486 that needs a few ISA slots (btw are they 8 bit or 16). There are...

prob strike my other reply, I read just now you want to keep the old pc in there for some license issue, understood more or less but wouldnt you have your ...
... never trust floppies as a long term backup. They're only fine to move data around for short times (days). This is my experience at least. HTH Francesco...

I was digging around and found a bag full of Motorola xstrs, all TO-92, that are marked on the top line with xxx-x (many variants like 947-1, 776-1, 550-1,...
Can you tell I've going through boxes...? Does anyone know what the 3rd character of the EIAJ xstr code signifies? (ie- 2SA.., 2SB.., 2SC.., 2SD..) You'd...
Hi Dave, ... Here you have it: 2SA- Transistor, high frequency, PNP 2SB- Transistor, low frequency, PNP 2SC- Transistor, high frequency, NPN 2SD- Transistor,...
... That is what I was trying to affect. ... If you can find an identical model drive, I have had 50/50 results swapping the motor driver/controller boards. I...
Thank you Jim. I will check on that today. The troubleshooting procedure shows that it is failing in the analog section. Possibly these regulators are the...
First off i would remove all modules and see if the mainframe still indicates over current , if one of the modules has a problem and overloads the MF then you...
... I don't have the distribution floppies. I have the SW on the 170 MB HD, and now on a backup floppy set that includes the W3.1. HP sold the system with the...
... ========== In days gone by, I was able to fix an ST-238 I found in the trash by replacing a driver transistor, but would not attempt that here. Boy, was...
Hello again, Just an update on this - and apologies for the delay... Cutting a long story short, it was the ROM. I got lucky because I was trying to fault-find...
Lothar, Thanks for responding, I have the power supply sitting on my bench, removed from the mainframe. I disconnected the fans and interconnect cable and it ...
Where can I find a list of what plug-ins fit the HP 5345A counter ? I tried a couple of used equipment sites but there was nothing there. Thanks, Dick, W1KSZ...
Dick There is a list on page 1-2 of the manual which (i think )can be freely downloaded from a number of the free sites Basically it takes an adapter and it...
