I HAVE A COMMODORE C128 WHICH I USE IN THE CP/M MODE MOSTLY. I WOULD VERY MUCH LIKE TO KNOW IF ANY OF YOU C128 OWNERS OUT THERE HAVE THOUGHT OF USING 64K OF THIS MEMORY AS A RAM DISK WITH THE OTHER 64K AS PROGRAM MEMORY. IF SO, IF YOU CAN TELL ME WHERE I CAN GET THE SOFTWARE TO DO THIS I WOULD BE VERY GRATEFULL. OR MAYBE SOMEONE HAS TRIED TO WRITE IT THEMSELVES!

The C128 runs CP/M 3.0, which uses both banks of memory when normally operating. The extra memory allows a larger TPA, and generally results in a faster machine. The RAM Expansion module (1700,1750) are configured as RAMDisks in CP/M, giving you up to 512K of RAM Disk, as drive M: WordStar will load in about a second off of drive M:, other things are similarly very fast. -- /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ Dave Haynie {caip,ihnp4,allegra,seismo}!cbmvax!daveh A quote usually goes here, but its currently being rennovated. These opinions are my own, though for a small fee they be yours too. \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

Errrmm, doesn't the C128 run CP/M Plus????!!!!!! If so, you need both 64K pages:- one for system and one for TPA - this saves you warm-booting all the time and having a system eating up 1/4 of all your discs. -- Richard Jennings (incomprehensible jargon follows): _^_ jennings@sage.cs.reading.UUCP <o|o> / \ - remember space invaders??
