Hi Mike,
Well it?s certainly nice to know the Cromemco is also another good option if I want to
try DRAM again, but I am feeling that a good SRAM card maybe a safer option, and possibly
easier for me to repair if anything goes wrong.
Thanks for your thoughts
There is an Compupro / Godbout Econoram IV 16k board on
fleabay right
now, and I looked via the sellers link to a page on s100computers.com
which has a summary of the Econoram boards.
I think if you can find it, you would want a RAM16 or RAM17 board. I had
a RAM16 in a system at one point and that single board fills a normal
8080 type S100 system's memory space. unless you are using a board
such as the Northstar Disk controller(s) with memory space which is used
for addressing, you can fill all of the memory. Other boards that
consume memory space would be video controllers, or such as the Dazzler,
or rom boards.
The price of the Econoram IV puts you at 500 bucks for 64k, so that is
not good, and you probably would be best served with 4 16K boards alike
for various reasons. Sometimes they didn't play nice with each other if
the brands were not the same.
thanks
Jim
