Another alternative is STonehenge.  It is a ramdisk kit that connects to
the DMA (hard disk) port.  It allows 2 meg of 256 x 1 dynamic ram chips in
banks of 8.  I built one several months ago and have had very little
trouble.  It is available from:


          Contact: Ron Schreiner  (312) 520-8003
                   RONSAT Technologies Inc.

                   Buffalo Grove, IL.  60089

          The STonehenge kit priced at $169.95 includes;

            a.  STonehenge ASIC,
            b.  Double sided PCB,
            c.  20MHZ crystal,
            d.  DB-19 connector,
            e.  Documentation,
            f.  Software,
            g.  PGA socket for the ASIC.


          The Documentation and Software can be ordered separately
          for $10.00 (refundable with future purchase).

          The builder of the kit must provide the DRAMs, a 5V 2A
          power supply, and a few miscellaneous components that are
          readily available from electronic suppliers.

          Additional support kits that provide all the components
          are also available.

I have a software patch if you do get it.  There was a small bug in the
software.
