Basic pages about DISK II matainance and repair

Hello to all AF-members,
now the important parts of the referencepages related to DISK II Drives are completed....
Basicpage:
http://www.harrowalsh.de/Elektronik/APPLEBOX/appleboxdiskiipage1.htm
speedadjustment:
http://www.harrowalsh.de/Elektronik/APPLEBOX/appleboxdiskiipage2.htm
track zero adjustment:
http://www.harrowalsh.de/Elektronik/APPLEBOX/appleboxdiskiipage3.htm
so at this point i´ll just take a small timeout to solve other tasks waiting to be solved....
in a several days i will also create the final page related to the topic of the read/write compensation
that will explain how to optimize the performance of the electronics of the read/writehead and
common repairs at the analogboard ( for example exchanging the damaged chips if the cable to the
controller was plugged wrong way in and some chips got fried... so some drives might become resurected ... )
the other advantage of optimizing the electronics is that the drive probably can use the tracks 36 to 40
with safe reading and writing... and besides that page will cover some common tricks of protectionshemes
used in the old days to protect gamedisks....
up till then enjoy the pages have fun ... hoping the pages are usefull to the community and reduce threads to the topic of drives ....
sincerely speedyG
