Epson 286 PLUS User Manual

There are four SIMM sockets on the main system board

organized in two banks consisting of two sockets each. 

Each

socket can contain one memory module.

You must fill both sockets in any bank you use. The sockets in

Bank 

1 

are labelled U27 and U28 while the sockets in Bank 2

are labelled U29 and U30. Therefore, if you use Bank 

1, 

for

example, you must install one SIMM in socket U27 and one

SIMM in socket U28.

The following table shows all the possible SIMM configurations

for the Equity 286 PLUS. Do not install SIMMs in any other

configuration. Keep in mind that 

1MB 

of memory is already

soldered directly onto the main system board.
