(Missaligned or bent pins are a leading cause for memory failure).
Fix:
Reseat memory modules assuring good contact in sockets.
Check: If a hard drive with Commodore’s Fast File System is used, a
MASK
must be used
when 32-bit memory is installed.
Fix:
See User’s Manual, Section 9, Software Installation and Usage.
Check: Jumper Block
W1
for the jumper in position 2. (This is preset at the factory
and is satisfactory for most memory access speeds).
Fix:
Set jumper block
W1
to position 2. For additional information on SRAM
speeds and other jumper settings, please contact CSA at (619) 566-3923.
Check: CSA-MMR program is present in the start-up sequence and is properly adding
SROM, SRAM and DRAM if they are installed.
Fix:

Manual, Section 9., p. 17, “Mega-Midget Racer Software Installation and Usage).”
Symptom:
CSA RAM test consistently fails at address 02100000.
Check:
JP2
on the DRAM board should be set so that pins 2 and 3 are shorted.
Fix:
Set
JP2
so that pins 2 and 3 are shorted together. (See User ’s Manual,
Section 8, p. 15, “Jumper Settings”).
QUICK SYSTEM CHECKS:
Select the “68020 ANALYZER” ICON if using a coprocessor and “68000 ANALYZER” if no
coprocessor is installed. Run program number 2. The results should be:
Draw Time
SROM
SRAM
3 to 4 secs.
yes
yes
7 to 9 secs.
no
yes
13 to 15 secs.
no
no
Note: To achieve the results above, the Amiga DOS graphics library must be initialized by
clicking once on any ICON before running the “ANALYZER” program.
