Q15. Does the Epson EL 486UC computer provide parity checking for the
main system memory?
A.
To keep the system cost as low as possible, the EL 486UC computer was
designed not to perform parity checking on the main system memory.
This decision was also made due to the fact that the SlMMs available today
are much more reliable then they were in the past and that the lack of
parity checking on this system should not be a major concern to the
majority of users.

Q16.
Can the Epson EL 486UC computer be upgraded to support an
optional external secondary cache?
A.
Yes, the Epson EL 486UC computer can be upgraded to support an
optional external secondary cache of either 32KB or 128KB. This cache is
provided by installing optional Static RAM (SRAM) memory chips on the
computer's main system board. A external secondary cache is a good
method to increase system performance.
