Page 22 of the “Memory Plus Installation Guide” lists switch settings for a 256/640K motherboard. The switch settings only apply if the Memory Plus is to backfill from 256K memory. The cache jumpers on the MACH 20 should be set to 5 off, 2 on, 1 off, and C off. If all 640K memory on the motherboard memory is to be used, switches 3 and 4 on SW1 should both be set to off, and the cache jumpers should be set to 5 on, 2 off, 1 on, and C on.
