APPENDIX
Appendix 3.3.5 Handling conventional memory cassettes
Conventional memory cassettes A1SMCA-2KE/8KE/8KP (for A1SCPU) and A2SMCA-
14KE (for A2SCPU) cannot be used for A1SHCPU and A2SHCPU(S1).
(Used only for A1SJHCPU(S8).)
The new type memory cassettes A1SNMCA-2KE/8KE/8KP (for A1SJHCPU(S8)/
A1SHCPU) and A2SNMCA-30KE (for A2SHCPU(S1)) should be used.
Appendix 3.3.6 Replacing the A2SMCA-14KP (when A2SCPU + A2SMCA-14KP has been used)
When replacing the above with A2SHCPU + A2SNMCA-30KE, the area *1 cannot be used
for the extension file register.
When the area *1 has been used as the extension file register are, the system of
A2ASCPU(-S1) + A2SMCA-14KP should be used.
Appendix 3.3.7 Restrictions on microcomputer programs
When using the microcomputer mode, the following changes are made in the
microcomputer instructions.
Changes by Replacing AnSCPU with AnSHCPU Corrective Action
When REP LODSW and REP LODSB instructions are used Refer to the following program example.
Program example
AnSCPU ...... The contents of the memory specified by the SI register are
transfered to the register of AL (8-bit operation) or AX (16-bit
operation) for the number of times specified in the CX register.
After the instructions are executed, the CX register value
becomes 0.
AnSHCPU.... The contents of the memory specified by the SI register are
transfered to the register of AL (8-bit operation) or AX (16-bit
operation) only once regardless of the value of the CX register.
After the instructions are executed, the CX register value does
not change.
