WE DO IT WITH MIRRORS!
(and some very sophisticated state-of-the-art memory design)
65,556 BYTES
Your dream can be a reality with the Prime Radix Corporation's
64Ktm memory system at a very cost-effective price. And
because it is a standalone memory system, you've got the
advantage of greater flexibility not ordinarily available from
add-in memory. Some of the features are:
-
The 64Krn is fully buffered, presenting one TTL load to the
memory bus.
The 64Ktm is digital group bus and ALTAIRtm™ bus
compatible. When ordering, you must specify the bus
architecture. A plugcard and cable will be furnished for the
particular bus architecture you specify.
The minimum complement of memory is 40K BYTES, with
starting address locations at OK, 8K, 16K, or 24K. Switch-
able memory protect is in increments of 8K bytes on 8K
boundaries.
The 64KT™M comes assembled and tested with its own power
supply, attractively housed in an aluminum cabinet, ready to

cost).
The 64KTM has an expandable organization to other bit
word lengths.
