Larry:

Perhaps you need to use Fast Page Memory. Many
times a computer system won't let you mix RAM types.

Try the EDO by itself (if possible); if it works, you know
the existing RAM isn't compatible with the EDO. If it
doesn't work, then try a Fast Page SIMM (of your own).

If that doesn't work, yes, then try a true parity FP SIMM.

The manual doesn't tell you what RAM you can add?
Also check to see if 8MB SIMMs are even acceptable
(I had an old Gateway 486 that didn't accept 8MB SIMMs
but saw them as 4MB SIMMs).
