Note: If your system does not use the PRAM card specified in B through D below, proceed to RAM MEMORY
SELECTION. If AT ANY TIME you have closed a total of 8 switches (regardless of what step you are on),
proceed to SYSTEMS WITH MEMORY EXPANSION.
A. PRAM CARD 1
1. There is ALWAYS a PROM chip in IC8 of PRAM card 1, so close switch 7 on switch package J3.
2. If there is a PROM chip on ICl , close switch 8 on switch package J2. Otherwise, open all switches on J2
and go to RAM MEMORY SELECTION.
B. PRAM CARD 2
3. If there is a PROM chip in IC8, close switch 6 on switch package J3. Otherwise, open all switches on J3
and go to RAM MEMORY SELECTION.
4. If there is a PROM chip in ICl, close switch 5 on switch package J2. Otherwise, open all switches on J2
and go to RAM MEMORY SELECTION.
C. PRAM CARD 3
5. If there is a PROM chip in IC8, close switch 4 on switch package J3. Otherwise, open all switches on J3
and go to RAM MEMORY SELECTION.
6. If there is a PROM chip in ICl, close switch 3 on switch package 52. Otherwise, open all switches on J2
and go to RAM MEMORY SELECTION.
D. PRAM CARD 4
7. If there is a PROM chip in IC8, close switch 2 on switch package J3. Otherwise, open all switches on J3
and go to RAM MEMORY SELECTION.
E. RAM MEMORY SELECTION
Note: You have now set switches to address all of your PROM memory in the system. You are now prepared
to set switches for addressing all RAM memory which will be used. Proceed to Step 8. If your system
does not use the specified PRAM card, or if your count of closed switches reaches 8, go to SYSTEMS
WITH MEMORY EXPANSION.
8. On PRAM card 1, close switch 1 on switch package Jl .
9. On PRAM card 2, close switch 2 on switch package Jl .
10. On PRAM card 3, close switch 3 on switch package Jl .
11. On PRAM card 4, close switch 4 on switch package Jl .
12. On PRAM card 5, close switch 5 on switch package Jl.
13. On PRAM card 6, close switch 6 on switch package Jl .
14. On PRAM card 7, close switch 8 on switch package Jl .
Note: At this point all your RAM and PROM memory has been addressed. Switch package J4 is used for
systems with memory expansion. it will NOT be used with this PRAM board (562-049) so set all J4
switch packages as follows:
CLOSE switches 1,3, and 5
OPEN switches 2,4,6, 7, and 8
IMPORTANT NOTE!
ENSURE THAT ONLY ONE ROLL SWITCH ON EACH SWITCH PACKAGE (Jl, J2, AND J3) IS CLOSED.
