HDMC Changes (3)

Registers

• This is a very complex class (particularly the GUI) with many supporting classes
• Warning: difficult to understand and maintain and thus might act as a brake on other developments

VME Access

• At present only A24 access is implemented (I think?)
• Not clear if present Address classes are sufficient to extend this to A32.
• Some redesign of Bus and Address classes may be desirable
• Presently offsets are variously expressed in bytes, words or longwords.
• Less error prone if everything is in bytes - but repercussions on existing parts files
