I have a IBM PC with two 320kb disk drives,256k and a monochrome screen. I have been having a problem with Wordstar. In the middle of everything the screen goes blank and on the top left hand corner of the screen it says parity check 1 . The only way to get rid of this is to turn of the computer. HELP!!!!!!!!! It usually happens when I am editing an already made file. Could it be a bad copy of Wordstar or is it the machine. What does parity check 1 mean anyway???????? I will appreciate any advice on the matter. Thank you in advance, yitz twersky P.S. please send all responses to [user twersky at aecom] ---

I have a few questions for those PC hardware people "in the know": 1). I am trying to hook up 2 half-height floppies to my IBM-PC. One of them is a Teac the other a CDC. The drives are connected to the proper ribbon cable to a Maynard controller card. The system boots fine and diagnostics say I have 2 drives. BUT.. when I try to format a disk using version 3.00 format, just before I get the "formatting complete" message BINGO I get a PARITY CHECK 1 message. Yes I have removed the terminating resistor from drive 2 (the CDC). Question, what does the DS0, DS1 jumper do? Do I have to change these and what do I have to change them to? 2). I have a SIGMA 400 graphics board installed. NOTE: it has an on-board ROM which gets initialized upon boot-up. The problem here is that if I don't have the DOS disk in, the system should initialize to ROM BASIC but instead I get PARITY CHECK 1. I also have an AST board with an additional 384K on it. Is there some contention problems between ROMs? 3). Just how flukey is DOS 3.0? Thanx in advance, -mike- ihnp4!ihlpm!michael1
