Hello!  Congrats on your purchase of your Zip.  I did the same upgrade from
16K to 64K cache myself, and here is the info:

        The company is called Microprocessors Unlimited, Inc.,
                              24000 So. Peoria,
                              Beggs, OK 74421

                              (918) 267-4961

        They usually have an ad in the Computer Shopper, and here is the info
you'll need when ordering the cache rams:

        4 X  62256-35  (four of the 62256 cache chips, at 35 nanoseconds)

                        You might want to get slower chips and save a few
                        bucks, but the problem with that is IF you get
 			an upgrade to like, 10 Mhz, you will have to spend
			money on faster cache chips again, so with 35 ns
			cache chips to begin with, you'll be set for speeds
			up to around 11 Mhz (hey guys, this is what I read,
			correct me if I am wrong.)

	At the time of my purchase (Jan 2, 1992) each chip costed me $14,
and four of them came out to be $56.  With packing, shipping, etc., the total
cost came out to be $63.00, a pretty good deal.  The price should be lower
now (I think, or they might not be.)

Oh, I left out the full detail on the chips, here they are:

	62256-35	32Kx8	35 ns	Sony  CXK58258p-35  CMOS.

Hope this helps, and your are welcome.
