Tall Tree Systems J-RAM 2 Memory expansion board. Asking Price: $550
This is a memory expansion board for regular PC/XT machines,
including clones. It is not suitable for Micro Channel
machines (but OK for PS/2 30 and 25). You can use it:
(a) As a RAM disk with 2Mb memory. You can re-boot without losing
data--unlike many other products.
(b) As a disk cache. You can cache the whole 2 Mb.
(c) As a combination of (a) and (b). You could have a 1 Mb RAM
drive and a 1 Mb cache, for example. I have the software to
do both.
(d) You could take the 256K DRAM (150ns) chips out of the board
and use them to populate other boards. There are 72 chips on a
2 Mb J-RAM board. Street prices for these chips are $15-$17, so 72
would cost you a minimum of 15x72 = $1080.
