Epson EL 486UC - Manual (Page 14)

Math coprocessor
You automatically install a math coprocessor when you
upgrade your system with a 486DX microprocessor, because
the coprocessor is built into the 486DX chip.
Memory
By adding 1MB, 4MB, 8MB, and 16MB SIMMs (single inline
memory modules) to the main system board, you can expand
the computer’s memory up to 32MB.
Your system also supports video memory upgrades to 1MB
and cache memory upgrades of either 32KB or 128KB.
Drives
Your system can support up to three internal mass storage
devices, including hard disk drives, diskette drives, a tape
drive, or a CD-ROM drive. As your storage needs expand, you
can install additional drives.
