A while ago Joe Garvey from California Microwave posted this view of
the DRAM configuration of our Visual X-19 X Display Station:

:The DRAMs I used were from Texas Inst. # TMS44C256-10N, cost ~ $17/ea.
:These are 256Kx4 parts.

:There are no jumpers to set... tools required one phillips head screwdriver!

That configuration will work but we would prefer to see people doing it
this way:

.-. .-. .-. .-. .-. .-. .-. .-.          .-. .-. .-. .-. .-. .-. .-. .-.

`-' `-' `-' `-' `-' `-' `-' `-'          `-' `-' `-' `-' `-' `-' `-' `-' 

This is better because it gives the X-19 more contiguous memory.  If you have
any questions please give us a call.
