   -> I have been running PCB since v14.5a. Since OS/2 capability was   
   -> introduced all installations have included both DOS (2 versions) and   
   -> the OS/2 files.   
      
   -> Having run it first under PC-DOS / Desqview and then under OS/2 I can   
   -> strongly recommend running under OS/2.   
      
   -> Maybe you could find an OS/2 Warp 4 installation kit = 2 CDs   
   -> somewhere.   
      
   Once upon a time, before IBM abandoned it, I used OS/2. Seems like   
   you would need some old hardware to have Warp 4 compatible devices   
   though.   
      
   I did some testing with the DOS version on WFWG 3.11, using the updated   
   WFWG serial driver and a cheapo 2-port multiport serial card. I got 2   
   nodes running, an upload on one, a download on the other, and copying a   
   file across the network at 100mbs, all at the same time, without   
   dropping any characters on the serial ports. The file copy throughput   
   was about 80mbs, or 80% of wire capacity. Pretty good for Windows 3.1.   
      
   It looked so good, I planned to use it. But later I discovered that   
   running a big compile job and opening DOS windows at the same time would   
   crash the machine. Seems my CPU is too fast for Windows 3.1. Windows 95,   
   unpatched, is known to have problems with CPUs faster than 350mhz. And   
   I'm guessing similar problems lurk in Windows 3.1. Too bad there are no   
   patches for it. I tested Windows 95 too, but its network thoughput is   
   pretty bad, only about 30mbs. I also tested Windows 98. They fixed the   
   network problem, but messed up the serial driver.   
      
   The only solution would be to run old hardware, CPU <= 350mhz.  But   
   that's hard to find nowdays, even on Ebay.
