I have a Prism III which does not use PrismUp so some of your problem is 
unfamiliar to me.  However I can tell you that you do not need to run 
OS/2 Warp 3 inside an emulator to get it to work on a modern computer.  
I am running OS/2 on a hand-me-down Dell GX150 (a PIII) but it should 
run on much newer machines.  Naturally it runs very fast on these 
machines.  The only thing I am not sure of off the top of my head is 
whether it will run on a dual-core processor.

What you need is updated drivers to handle hard drives bigger than 4GB 
and probably updated drivers for video and network cards.  These are all 
available from the hobbes archive at  For the drive 
you can use Dani drivers, most likely danis506r181.  The others I'd have 
to look up depending on your video card and NIC.  Let me know if you 
want to go down that path and I'll find more info.

I strongly recommend two other variations on the standard setup.  First 
I use NetOp remote control software to allow me to control/monitor the 
mass spec from my office.  It also allows me to transfer files to my 
office machine for backup and post-processing without having to buy a 
(very expensive) Windows client for OS/2.  The mass spec computer is 
also invisible to the rest of the Windows network - which is good. 

The second variation sounds complex but it was worth the effort.  The 
hard drive is partitioned into a c: and d: drive.  The operating system 
and some other software (eg a program for taking screen shots - so I can 
keep copies of background scans, peak shapes etc) sit on c:.  The d: has 
the Isotech directory and a command-line only version of OS/2.  There is 
a boot loader which allows me to select which one to boot.  Once the 
system was working I zipped the d drive and transfered it to my office 
machine.  Then I rebooted into the d drive and from there zipped the c 
drive, then rebooted back into c: and transfered the zipped c drive to 
my office machine.  That gave me a zipped copy of the whole 
installation.  When the inevidable hard disk crash occurred it was 
pretty straightforward to unzip the images onto a new disk and get going 
again in a day or so.  There were some minor issues but I've forgotten 
the details.  (Of course the data is backed up after every run so 
nothing was lost there.)

Let me know if you need any help and I hope you get you computing 
somewhat closer to the 21st century.
