Subj: REPLY TO MSG #122 (REPLY RE: M100 EXPANSION)
-=< insert wearry face here >=- The booster pack uses the concept of RAM-disk. The MDL 100 is still limited to manipulation of 32K of RAM at any one time (I won't get into how the I/!M pin could be used) but there's no reason that 32K can't be stored in several different places; tape, disk, CD, BBS, MicroTardis Paks, RAMs. All but the last take a discernable time to transfer/load into your working memory (working directory?), all except the last two. Most of them require peripheral devices, but how far is your link from your machine to the periphery of your domain? How about if the addition (out of Working Directory) RAM was located only centimeters away and accessed over the machine's system bus. That's what the booster pack has. In fact, some of those 'other directory' RAMs can actually be ROMs. Now all you need is a table as to where in the Booster Pack the desired files start and you can access them. Some you have to move intor your 'working directory' or 'work space' some can be invoked without the copy over. It's the daemons that do the sorting and the shuffling. Let's keep them in fresh alkaline AAs forever.
