It cost me $130 and no slots to do that. I got a RAM-PAL chip from First
Capitol Computer in St. Charles, MO , 800-862-8948, 314-946-1968, for $40 and
18 256K chips for $90.

I just installed an upgrade kit for $20 from Microprocessors Unlimited
of Beggs, OK (phone 918-267-4961). The kit is really just a new PAL
memory address decoder. They were selling NEC 256K 150 ns rams for $2.75
each. Hence a memory upgrade has cost me $69.50 (plus shipping, etc).
The PAL permits using the original 64K rams (up to 5 banks) with J401 in
the first position, and using 256K rams (1 or 2 banks) and 64K rams (up to
3 banks) with J401 in the second position. Thus adding 18 256K rams to
a full (320KB) memory board yields 704KB! Not bad for under $70.00!
