Hmmm... what you say above concerns me... The Paula and Parallel port have nothing to do with eachother... The Paula is what is used for the serial port... (the parallel port is INDEED run via the 8520's) These two points lead me to this last point: Did you know that the A1000's serial port is a FEMAL D-SUB 25 and NOT a MALE?! The SERIAL port is the female connector and the MALE is the parallel port! You may have plugged the printer into the FEMAL D-SUB serial connector thinking that it was parallel... that could indeed blow your paula... I have seen it many times on the 1000... besides THIS parallel difference.. there are also some parallel port pin wireing differences that can cause damage to your equippment if a SPECIALLY modified parallel cabel is not amde for it (some pin cutting/soldinger is needed)... The funny ting about the 1000 was that the serial and parallel port were the opposite genders as were seen on the IBM clones. This was because the original RS-232 standard (I forget which revision) also called for a FEMALE gender on DTE devices... When IBM created the PC.. they, of course, went directly AGAINST that standard and created their OWN... so.. thus.. now everyone thinks that RS-232 DTE's are supposed to me MALE... well.. the lie has propagated to the point where practcically.. it is... But if a newbie buys an A1000... he should be forwarned of this factoid... If you already knew all this.. I'm sorry for wasting your time with it.. it's just that from the sounds of your "incident"... it sounded like you may have plugged the wrong thing into the wrong port...
