Does anyone recall the names of some software that will allow
a person to use extended memory as expanded memory? Please
reply directly and I post a summary if netfolk request it.
Thanks.

The following was extracted from EMSIM.DOC: The EMSimulator or Expanded Memory Simulator, bridges the gap between your application software and the AT's previously unusable Extended memory. Now programs such as Lotus 123 v2, Symphony v1.1, Lightning, Reflex v1.1, and most L-I-M Expanded Memory compatible software can access up to 8 megabytes of your AT's extra memory. By removing the 640K restriction and limitations of conventional memory, expanded memory makes large spreadsheets and databases a reality. The EMSimulator is compatible with the IBM AT and most AT "Clones" including Compaq's 286 series. Installation of the EMSimulator is quick and easy requiring only an addition to your "CONFIG.SYS" file and that extended memory be available via an expansion board as mentioned above. Compaq 286's and some clones already have extended memory capabilities so additional boards may not be required! Contact us or your dealer for more information. ----------------------------------------------------------------- I think they want $49 for the program which seems steep when there are most likely other less expensive alternatives. EMSIM.ARC is available at simtel.

What _wasn't_ quoted from the documentation was: This document and its respective files are a complete working limited evaluation version of the EMSimulator. All functions are --> implemented with the exception that simulated Expanded memory can --> not be larger than 256K in size. Users are allowed to distribute this version freely as long as it is not modified in any way. Anyone who finds the EMSimulator useful are encouraged to purchase the complete package which included printed documentation and an unrestricted version, which will allow up to 8 megabytes of extended memory to be used as expanded memory, for only $49.95. ("-->" are mine - kde) This is from the USENET distribution of the program. It is what we are calling "crippleware." kEITHe

I have a theory, but it sounds like the cure is worse than the disease. I think they steal 64K (out of your 640) and use the INT 15 extended memory block copy to copy data in and out of that 64K block. I would like to find out that there is a better way! f i l l e r -- Peter Fales AT&T, Room 2F-217 200 Park Plaza UUCP: ...att!ttrde!pfales Naperville, IL 60566 Domain: pfales@ttrde.att.com work: (312) 416-5357

I don't know technically how they work, but I do know that they take 64K of
conventrional memeory, which makes them almost useless at times.
