1. Timex FDD3 documentation

Hello!

I've just documented top board of Timex FDD3 in Eagle 4.16.
One of the two I know - with eight 4116 memory. (The second
has two 4416.) The file is on:
http://8bit.yarek.pl/computer/timex.fdd3/

After several hours (6:00 CET) the page will refresh,
showing some more pictures. I've described them today.
Some of the pictures are of Unipolbrit Memory Disk.
This is all in one (power supply, computer and 3"
drive).

I have a problem with the voltage converter. It doesn't
produce -5V correctly. I get -2V or so. Does someone have
experience with this circuit?

Have a good time!
