Now it all starts making sense.

Due to people complaining about the speed with 486 DX2-66 the main
loop for SPP and PS/2 mode was "optimised" with assembler. The only
option I have is to back out that change (just for you) and add a delay in
the appropriate areas to make things work better.
The delay is more likely to be in the order of 1us, therefore a sub usec
delay system will be required. You are using 2.0.35 right?
PS: I lost three hours today as one of the concrete floor slabs "moved"
in the office.
Current project list:
a) Maintain Linux ZIP drivers
b) Create Linux chipset specific parport drivers
c) Start on ParSCSI drivers
d) Boot proms for parport devices (socket onto NE2000 cards)
Any assistance to clearing this list most welcome
