Question: How fast can the Zip GS be pushed without getting new SRAMs

or a new CPU? If I do need new parts, where can I find them

at the lowest prices?

Answer

------>

You may be able to get it to run at up to 10MHz by just replacing the

oscillator with a faster one for less than two dollars!

I have a Zip GS that came as a 7/32 and was used at 7MHz for a long

time. The board came with a socketed oscillator, so one day I swapped

the 28MHz oscillator with a 36MHz one. The computer booted up at 9MHz.

When the 36MHz osc was replaced with a 40MHz osc, the Zip ran at an

amazing 10MHz!

Your mileage may vary, though. The GS that this upgraded Zip resides

has a high output power supply.

Still, considering these oscillators cost $1.39 each, it is worth

trying an oscillator swap alone first.

If a faster oscillator alone won't do the trick, then a faster CPU

and/or faster cache chips may be necessary. The following are

sources for the parts (osc, CPU, and cache).

Here's what you need to upgrade to 10MHz:
