Chips
The memory sold in this system is 640 KB. It had a 150-ns access chip speed.
Amount
There are 2 switch banks located to the right of the memory banks that would change the amount of base memory on the system. The switches in both banks would either be "Even OFF/Odd ON" or "Even ON/Odd OFF." If the even switches were on, the system would have 256 KB of memory; if all the odd switches were on, it would have 640 KB of memory. (See Layout for exact position of switches.)
Removal
Even if the base memory was changed to 256 KB, the memory chips had to remain in the sockets to complete the circuit.
