The cpu and the video chip 4510r5 4567p don't work, in whole or in part on a tab ver 2 (a or b) it is logical the inverse; a cpu or 4510 4510 r 3 and 4 cannot operate on a card rev 5. My luck is the autonomous capacity to accomplish what I have in mind. Use an external structure to materialize the ideas most fools would cost so much that dreams remain such. We had a commodore 65 rev 2b, all standard components but a cpu 4510r5 and a 4567p video chip. So I researched and designed a cpu 4510r5 adapter (see picture below).
And after unnerving and rebutting evidence controls the socket adapter is inserted.
