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.
There are three sets of user selectable configuration plugs on the Series A
BASIC module. You can use these configuration plugs to select:
