Hmm, maybe the A3000 has some slightly different timing in the access of the chips. Btw, does the IO ports reside in 32-bit memory? As it is the centronics interface, even microseconds can cause problems... >John M.

If you want to, you might try swapping the two CIA chips in your A3000 to see if the problem goes away.... Of course since the problem chip would still be in your system, a different problem might show up in another area.... (like drive problems!) But at least you would have pinned it down and could get a replacement chip.... Good Luck -Mike-

That kind of rules out the CIAs. Another thing might be that the QMS 410 has some parallel port problems. The local QMS rep. has no story on that. I have also been loosing characters on an EPSON GQ-3500 emulating HPLJ. The fact that some kind of error appears on two different machines leads me to thing of some design flaw. > -Mike- But thanks anyway, Yours is among the few answers I've got. -- Svante Gellerstam svante@kberg.se, d87sg@efd.lth.se
