[comp.sys.ibm.pc.hardware] Wangtek PC-36 controller upgrade ?

tron@db.toronto.edu ("Carlos G. Mendioroz") (03/01/91)

I'm having trouble with my old (5 years) PC-36 controller.
It seems that there is some kind of incompatibility between it and
new 386 machines ... so they (Wangtek rep) told me I have to change
it for a newer one (a 30850-008 for about $230), though some time 
ago somebody told me (sorry, I don't remember who) that a firmware 
update can solve that problem.

This controller has worked fine
on AT's and on a Wyse-386 (16Mz) but is refusing to work now on 
an Everex step 20. (It reads tapes but does not write them ok,
some problem with the file-mark writing phase...)

Anyone with such an experience ? 
Any cheaper QIC-36 controllers out there ?

  By any chance are you running your bus faster, or forcing zero wait
states on the AT bus? I ran one of those on a 486-25 without problems,
but I believe they dislike anything faster than 8MHz bus, 1w/s.
