A-22
Note: If the disk is being used as user memory (instead of RAM), the user
memory you have available is limited by the free space currently available
on the disk. The disks have a capacity of 720 Kbytes when newly
formatted.
If you need to find out what your UniSite's current configuration is,
remember that both the RAM size and software configurations appear on
the upper-right portion of most of the UniSite screens.
The SetSite module is shown in Figure A-22. The eight 40-pin DIP sockets
have a "mass-actuation" feature: there is only one socket lever on the
module. Moving this lever moves ALL the socket contacts.
The socket lever has three positions: open, close, and start. Because the
lever is spring-loaded, it will automatically return to the closed (straight
up) position after being pushed to the start position. The start position—
lever pushed forward toward the ACTIVE/READY indicator panel—
initiates Load, Program, or Verify operations, just like pressing E
the terminal keyboard.
The socket lever also functions as an interrupt or B
the switch back (thereby opening the socket contacts) while an operation
is in progress, that operation will be halted.
