Overclocking the 200LX

[Eugene Kang]

I saw this page where this guy was offering a kit (consisting
of three or so components) which will double the speed of
the 1/200LX. Will this damage it in any way? Does anyone have
the plans for it? US$50 for three components sounds a little
too high.

btw, the address is :

btw, is US$639 for a 2MB RAM unit a good buy?

thanks

If you have a good electronics outlet that lets you buy
small quantities, crystals, etc., without a minimum
order, then you can save quite a bit. And oh, this
assumes you know how to program and write a device
driver to compensate for the speed increase.
This would probably take an amateur a month or so.
Is $50 worth a month of your time? If it is,
then do it yourself by all means. Enjoy! Adam.

If you can find the odd-ball frequency, miniature crystal somewhere else,
you can get the necessary drivers off Compserve...maybe even eddie. I
think the guy selling them had a custom run made, which took a good chunk
of change upfront. The kit is the 2x crystal (double whatever the
current freq is, ie the new xtal is about 31 MHz) a couple of passive
parts to clean up the clock coupling, a disk with the necessary software
to make the palmtop work after the upgrade, directions and a Torx T6 bit
to open the HP. $50 didn't seem unreasonable to me.

My sample of 1 :-) still works fine - just faster. Voids the warranty
though.

Flash card/SRAM card access won't be any faster, but CPU intensive stuff
(123 recalcs, running macros, etc) are much faster.

Cheers,
Bob

I agree the upgrade for all the work that he has put into it is very
resonable in price.

Here's a question someone might be able to answer. Does the clock speed
up affect compression software preformance (Stacker or Jam). I know the
biggest limitation is the speed of Flash memory but was just curious if
anyone noticed a difference?

Crystal MUST be Fundamental type and the exact frequency is important although there is some
tolerance.

I just checked with EduCalc and they carry it at $34.95 + $6.95 S/H.
