Digital Research (Computers) in Dallas, now has a 1 Meg RAM disc card for S-100 systems. A bare board with software and documentation runs about $70. It is 4 banks of 256K DRAMS with parity, and uses INTEL's 8203 memory controller chip. I don't know how fast it will run, you'd have to check that out with them. I'm building one now, and considering my past experience with their quarter Meg RAM disks ... I can't wait to get it running. They claim that it is possible to stuff up to 4 of these cards in one buss, so one could have bunches of RAM disk for little $'s (compared to the prices you guys are talking about). It is also available in kit form, but I'm not sure of the price. Check it out!!
