actually history wise, there was a memory specification called
LIM (Lotus/Intel/Microsoft) that used a 16K/32K/64K memory slot
in the 1 meg real memory region where the 8088 could access it
to bank switch blocks of memory in and out of the window area.
Lotus 123 was a big user of the Expanded Memory because of the
typical size of spreadsheets would quickly eat up normal memory
and require disk access that would slow down the spreadsheet
even more. Memory boards that were referred to as extended memory
were the ones that could be accessed by 286 and above processors
by having the processor go into protected mode.

As someone already pointed out - prices only drop drastically
per meg for
new technologies. For old memory, the price drops
slowly, then
it rises
a bit once it's old enough to be legacy. Try and
find some
largish 30-pin
memory now - it's not the $25-$40/meg it once was,
but some
places still
get a lot for it (not that they *sell* a lot ;-)

Yes, that and productivity apps that needed more space than (spreadsheets, CAD packages, etc.) plus games. There
were plenty
of DOS games that needed more than ~500K.
