When you have a 10 Mhz AT clone with 1 Mb of RAM, but where the 384 Kb above the 640 is not LIM compatible, what do readers do to get it LIM compatible for use with 1-2-3 and the like. I have seen a LIM simulator called SOFTBYTES advertised for 49.95 in the UK which takes 64k of working memory but gives you the 384 back. Any experience or suggestions....

Do not waste your time (literally) with LIM EMS simulators that work out of extended memory (or disk) to run Lotus 1-2-3. There are two very big reasons. A) It's tremendously slow. Your spreadsheet will slow down by an order of magnitude, or more. Minimal recalc might help a bit, but not a lot. 3-2-1 Blastoff won't do anything much for you either. B) With actual bank switched boards, it is possible to have the same page in two different banks. 1-2-3 will, Lotus says, sometimes do this. If it then writes to one bank, it expects the other bank to be updated. That doesn't happen with a simulator. WRONG ANSWERS. If you want EMS, kludge as it is, get a card that does both EMS and extended memory, and can easily be switched. There are many switchable cards, not all are easy. Or, if you have a 386, I think you can write an actual driver that uses 386 paging registers to do the job properly with real memory. Or if you have ram at C000 or thereabouts, and you want to only simulate 64K of EMS, that's fine. -- Brad Templeton, Looking Glass Software Ltd. - Waterloo, Ontario 519/884-7473
