I will greatly appreciate if you can scan necessary pages. How many
pages are electrical schematics/how many can you scan?
Also I can give you a fax number which should be free of charge for
you, but scannig it and sharing to all PC3k users is the best idea.

If there is too much pages to scan, especially I'm interesting in the
circuity around ISA(like) connector, DMA,IRQ controllers and CPU.

Are there any other details about the ISA-like connector?

The connector is My home production. As well as serial and paralel. In
fact I never tried to get them from shops. Because there are probably
only few pieces of this palmtop in Czech republic.

 I put CC to the mailing list for this e-mail.

Good idea with 200 LX. If there is anybody having contact to a person
having 200 LX please ask if he knows details. At least to make a
bootable SRAM with 5.0

Do I remeber well that there is a 27C810 EEPROM in PC3k? (Probably not,
but there is something like this.)
