Tony, thank you for your offer to supply replacement M452 Variable Clock
modules for the console. We already have one jumpered for 110 baud for the
Teletype. The other two M452 modules should be jumpered for 9600 baud and
38400 baud. The second serial port uses a M405 Crystal Clock module with a
Do you want 3 separate modules, or one switchable, or what?
different pinout and clock outputs than the M452. We
don't have any of
these modules, so the three that we need should be jumpered for 110 baud,
9600 baud, and 38400 baud. The shipping address for the RICM is on the WWW
page.
Hang on. I thought the M405 was just a crystal oscillator without a divider. Are
you sure there is no extra division on other modules? 110Hz is very slow for
a crystal oscillator, after all.
