Q: Can I use other types of diskette drives with the Apex?
A: Half-height, 720KB 3 l/2-inch diskette drives and
1.2MB 5 l/4-inch high-
density diskette drives are not
supported.
Q: Can I install a math coprocessor chip? What type do I
need?
A: A math coprocessor chip is an option that speeds up the
math functions used in many spreadsheet and math-
intensive software applications. You can buy the chip at
electronic parts retailers and computer stores (Epson
America, Inc. does not supply them). An 8087-1 math
coprocessor chip which runs at 10MHz is recommended
for use with the Apex computer. The math coprocessor
is installed in the socket provided on the Apex CPU
board.
Q: What other monitors are compatible with the Apex? Is it
possible to use a television set?
A: IBM-PC compatible RGB color or TTL monochrome
monitors work with the multi-graphics adapter card
provided with the Apex computer.
IBM compatible Enhanced Graphics Adapter (EGA)
monitors can also be used if an EGA video board is
installed (available from computer dealers).
