Which makes it a bit hard to read when used to using '>' etc.

I was a bit wrong with the number of diodes etc. please see:
My own solution was soldering a 25-pins female and male D-connector to 
eachother and place that between the origanal cable and the LPT-port. The 
transistors, diodes etc. were soldered on a piece of experimental print 
which was connected with two cables to this D-connector combination and a 9-
pin D-connector for the RS232 port

This is because of the tricky timing needed for some operations. In some 
cases you only have a window of less then 70 micro-seconds to react. With 
DOS you can time things quite good, but with Windows it can be horrible 
because of a bossy OS that sticks his nose in everything you do. 

Vice is a different thing because with emulation there is no external 
device putting a pressure on you. OK, I know that the new version can 
handle external drives as well buy IMHO it was only possible by using the 
massive power of nowadays processors. I wonder if it could be done with, 
let's say, a 100 MHz Pentium-1.
Spiro, maybe could you explain this a bit more, please? Thanks.

A personal note: there are a lot of discussions going on about "why doesn't 
Star Commander run under XP?" and "how can we can we make it work under 
XP". It works perfectly under DOS. So I have a 486-80 MHz doing this for me 
running under W98-DOS. And if I need to exchange files, I start up the GUI 
to be able to use my network. Really no Windows version of SC needed, I
