My brother recently bought a Commodore 128. He messing around with CP/M and is having a little trouble with it. It seems that there was a CP/M disk included with his computer. It has a bunch of useful programs on it. Some on side 1 and the rest on side 2, every time he wants to change the date or use the functions that are not on the boot side of the disk he has to flip the disk. This doesn't make any sense to me because I understood that the 1571 disk drive has to heads. Shouldn't the disk drive be able to access both sides of the disk without having to flip the disk. I am not too familiar with the C-128 so any information on this dilemma would be greatly appreciated. Thanks, Jeff Struven (Please excuse any random entries you see from me in netnews. This should be my first legitimate entry but I've made many a mistake in trying to learn the ins and outs of netnews. I apologize for any inconvenience it might have caused.) ====================================> <=============================

From: prindle@NADC Yes, Jeff, the 1571 drive can read/write both sides of the diskette in CP/M mode. The software distributed with the C128 assumes that the user may not have a 1571, but only a 1541, thus uses only single side format. Tell your brother to format a new disk (enter: FORMAT), selecting C128-Double Sided format. Then he can use PIP E:=A:*.* to copy all the stuff from one side of the original, and repeat that to copy all the stuff from the other side. The resulting disk will contain everything and be double sided. Frank Prindle Prindle@NADC.arpa

The first thing I did when I started to play around with CP/M was to copy both sides of the disk onto one 1571 CP/M format disk. (I think they even tell you how to do this in the User's Guide that you get with the C128). fred
