Data I/O 29A vs 29B diff?

[Wai-Sun Chia]

I noticed that whenever there's a discussion on burning [E]PROMs,
there's bound to be centered on the Data I/O 29B unit. And that seems
to be quite popular amongst classiccmp listers.

I may have a chance to acquire a 29A instead, so I submit to the
collective wisdom of the list as to what is the difference between a
29A and a 29B.

The million dollar question:
Would you get a 29A for yourself, or would you wait for a 29B? Why?
