Anyway, if the SCM90448 EPROMs for your M8189 KDF11-B
are actually
Motorola MC68764 / MC68766 EPROMs,
I have one board with MCM68766 and two boards with SCM90448
I have BP Microsystems device
programmers that can handle those. I have programmed some of those
myself for my own M8189 KDF11-B.
Excellent!
Are you looking to get set up with
the 23-380E4 / 23-381E4 M8189-BG firmware?
Yup! Actually hoping for:
MicroPDP-11/23 ROM v1.1 (23-453E4 and 23-454E4
Those Motorola EPROMs require a Vpp of 25 volts, which
is probably why
a lot of modem device programmers don't handle them.
OK!
