Questions on Apple //??

[Tan Yong Lak <yonglak@cyberway.com.sg>]

Just revived my Apple ][e and ][+ clone after many years under my bed.
Many unanswered questions after so many years...

Is there a scanned schematic of the //e PAL version?

Can anyone tell me whether is it possible to speed up the Microsoft
Softcard to 3Mhz
or faster? Does the AE Z80+ actually  runs at 4mhz?

Is there any tech doc regarding the working of the Zip chip or any
accelerator?

Where can I find a mini-assembler to do 65c02 codes?

Can someone tell me the dip switches do on the ComputerStop Omnivision
80 column card?
