Epson ActionTower 3000 Computer - Manuel (Page 11)

Five 16-bit, ISA-compatible option slots
Space for up to seven mass storage devices (four externally
accessible and three internal)
On-board support for up to two IDE hard disk drives and
two diskette drives (or one diskette drive and one tape
drive)
Math coprocessor integrated into the DX, DX2, and
Pentium microprocessors
Real-time clock and calendar on main system board with
built-in rechargeable battery backup.
Using the built-in interfaces, you can
connect
most of your
peripheral devices directly to the computer so you do not have
to install option cards. You can use the option slots to enhance
your system with extra functions such as a modem card, a
network controller card, or additional interface ports.
The shadow RAM feature allows your system to speed up
processing by moving the system and video BIOS into the
RAM area of memory.
Video
The local bus SVGA video interface provides data transfer at
the full speed of the processor, rather than at the standard
8.33 MHz ISA bus speed.
With 512KB of video RAM, the SVGA controller supports
standard resolutions up to 640 x 480 in 16 colors and extended
resolutions up to 640 x 480 in 256 colors or 1024 x 768 in 16
colors (interlaced and non-interlaced). With 1MB of VRAM, it
supports extended resolutions up to 1280 x 1024 in 16 colors.
