Series A Configuration Plugs
This appendix gives you the configuration plug settings for the Series A
BASIC module. If you have a Series B module this information is not
relevant. The Series B module does not have configuration plugs.
However, it does have configuration jumpers. These jumper settings are
described in Chapter 1.

BASIC module. You can use these configuration plugs to select:
