  I would have placed it more like 1978.

  Typically useless "gloss" site.

  Yeah.  I could look it up in a pinch (maybe), but replacement in the
manner you suggest *actually* consists of mounting a 6116 (2K RAM) chip
on a piece of perfboard, bolting that somehow to the motherboard, and
using flying wires to connect like pins to the DUR (Device Under
Replacement).

  In the process, you will most likely use the abovementioned chip to
replace *most* if not *all* of the 2101s.  Which is a Good Thing, as it
runs cool, is faster and (as a consequence of running cool) will, unlike
the original, never fail!

  I think you will have only one problem in doing the above (apart from
figuring out the address multiplexer circuit and modifying same); the
2101 had separate data input and output lines.  Use resistors.

  However, the alternative of finding and/ or using the exact
replacement chip, is just not meaningful any more.
