Upgrades
come in several
forms:
- A
double speed upgrade
crystal
kit
- An upgraded motherboard
Double
speed crystal
kits : Crystal plus a boot card with drivers
A double speed upgrade
crystal kit contains of a new specially made 32.000 Mhz
high-quality crystal, plus a new PCMCIA ATA or CF card plus adapter memory card containing
the double-speed drivers and example
config.sys
and
autoexec.bat
files. The card has most of it left for storage.
The original 15.8 MHz crystal has to be unsoldered, and a new 32 Mhz
crystal is then soldered in.
Your 200LX will then be slightly over twice as fast as
original.
Technically:
cylindrical 3x9mm 32Mhz fundamental mode crystal
The kit has a special base price of € 45 / USD 55.00, which includes
worldwide
shipping in a bubble envelope.
Additional crystals can be added a USD 20.00 each.
Below is a picture of a motherboard upgraded to double speed
showing the position of
the replaced crystal:
Note:
The mentioned 'Double Speed Driver' is necessary to adapt the
screen, system clock and serial port to the double speed. In some cases
the screen may be visible even without the drivers, but data
communication may not work.
You will need a fine-pointed soldering iron and fair soldering skills. When
in doubt, consider an upgraded motherboard, as we are not responsible
for no longer working boards due to your upgrade efforts.
Motherboards
A
motherboard allows you to upgrade your
LX to more memory and/or double speed, or replace a defective one.
You keep your old motherboard as well. The only tool you need is a
Torx-6 screwdriver.
Examples:
200LX
motherboard with 1MB onboard memory
200LX
motherboard with memory upgrade board
Upgrading with another
motherboard entails:
- removing
four rubber feet
and four torx 6 screws
- carefully opening the case,
detaching the battery clips from the
motherboard
- detaching the screen
flatcable from the motherboard
- taking out the motherboard,
putting the new one in
- reattaching the screen
flatcable
- reattaching the case bottom
- putting back the screws and
rubber feet
