Epson Equity 286 PLUS - Manual (Page 104)

Usually it does not matter which slot an option card occupies as
long as the card fits in the. slot. For example, you can place some
8-bit cards in a 16-bit slot. However, you must follow these
guidelines when deciding which slot to use:
An 8-bit card with an additional tab along the bottom must
go into an 8-bit slot.
If you install a disk drive controller card, place the card as
close as possible to the drive it is controlling.
Some option cards must be installed in a specific slot.
Consult the instructions that come with the card to see if
this is the case.
Follow these steps to install an option card:
1. If you have not already done so, remove the cover from the
computer. (See page 5-2 for instructions.)
WARNING
After you remove the cover, touch the inside back panel
of the computer to ground yourself and avoid an electric
shock.
2. If you are installing an option card that controls a mouse,
you need to change the setting of jumper J4 on the main
system board before you install the card. If you install a
display adapter card, you may need to change the settings of
jumpers J1,13, and J5. See page 5-7 for instructions.
