On the ZipGS there's usually 2 or 4 large SRAM chips. From the 
numbers on yours it should have either 8k or 16k cache. It can 
be easily upgraded to 64k cache for a significant performance 
jump. The W65C816PL-7 is a faster processor rated at 7mhz. The 
speed is set by the oscillator, a metal box or can near the 
upper left hand corner of the card. Speed is 1/4 of the 
oscillator. Most likely you have a 28mhz oscillator which gives 
a speed of 7mhz. However it may have a slightly higher or 
lower speed.

You can download a pdf of the manual such as it is from my website

There's some info on the card inthe FAQ which you can find at
