Hi Stan,
Thanks for the advice. The only 21A/22A I have ever seen, which
belongs to a friend, has the later version triggers. These timebase
plugins are not easy to find and I suspect "beggars will have to be
choosers" if a pair ever turns up. Mind you, the 21/22 works very
nicely indeed.
Incidentally do you know if it is possible to mix a 21 and 22A or 21A
and 22 in the one mainframe?
