Writing a sequence program to a memory cassette
A sequence program can be written to, or erased from, an A1SMCA-8KP or
A1SNMCA-8KP using a ROM writer/eraser.
If a memory cassette is installed in the ROM socket of an A6GPP or A6WU, use
either of the following memory write adapters.
CPU model
Memory cassette model
Memory write adapter
A1SHCPU
A1SNMCA-8KP
A6WA-28P
A1SJHCPU(S8)/A1SHCPU
A1SMCA-8KP, A1SNMCA-8KP
A6WA-28P
POINT
(1)
It is necessary to change the start-up model name when using SW
GP-
GPPA to initialize the ROM of the A1SHCPU/A1SJHCPU.
Set "A0J2H" for Version Q or earlier, or "A1S" for Version R or later.
In addition, select "27256" for the ROM setting type.
(2)
Take caution when a software version that selects "A0J2H" or "A1S" is
used to initialize the ROM, since the file register area of 8k points will be
reduced to 4k points.
As a countermeasure, use a software package for which A1SJH/A1SH
can be selected.
(1)
Mount a memory cassette to the memory write adapter. Couple the
connectors correctly.
(2)
Mount the memory write adapter coupled with the memory cassette to the
ROM socket of an A6GPP or A6WU in the correct orientation. The pin on the
cut corner side of the memory write adapter is pin No.1.
