– Application Note: Programming the MC1468705G2
the L1 versions of Motorola microcontrollers from the good old
days were hidden components with a ROM containing a monitor allowing you to
run a few lines of assembler for testing. For example, there was the 6801L1,
which contained the Lilbug monitor, which I had fun disassembling in the 1970s
and adapting to my needs in a 68701 that I was reprogramming.The MC1468xx
versions were only CMOS versions.
So, either you're programming an MC1468705G2, in which case you'll need to
build a small programmer, because these microcontrollers self-program by reading
an EPROM and scanning its memory locations using a counter. Or it's an MC146805G2L1,
in which case it's not programmable because it's hidden. I found a note AN1009
(Programming the MC1468705F2 Microcomputer).
It's the 28-pin version of the G2. If it's helpful, I'll scan it for you.
I don't have the EB-110.
