Main memory
Two locations (X150 and X151) are available on the system board for connecting
memory modules. If you want to remove or insert memory modules you have to
remove the drive carrier (see "Technical Manual" for the PC).
!
You may only use quick memory modules (Access time = 70 nsec or less)!
For the memory configuration we recommend the upgrade levels and slots
listed in the table .
