 |
|
Hi to all:
I have a old program made with Borland that runs fine on 286->PIII in
Win311, Win9x, Win2k and XP.
But it doesnt run in a 2Ghz P4 machine (I tested in W2k and XP), neither on
a Athlon 2.4Ghz.
I think that the routines to acces to paralel port key are 'time dependent',
the developer no longer supports
that application (They expect that I spend $995 in a upgrade). So I was
thinking in use a x86 emulator like dosbox or
something like this. Anyone has experience/recomendation in the subject?
What about 'underclocking' the CPU?
Any suggestion wilkomed.
Thanks
Saludos
Sebastian

It might be wiser to cruise around and find a used PIII for this app.
How about a laptop?
if it's having problems with the parrallel port "lock"
I wonder if you might not eventually have problems with winXP on the other
machines.
XP handles parrallel ports differently...

Maybe you could disassemble the .exe and patch the code that accesses
the port to add some delays. I recently added some delays to an old
DOS program that used I2C on the parallel port - I measured the
required delay at runtime so that it adjusted for the speed of the PC.
