Issue 6 board updates

[M68008]

Do you happen to know what are the main differences in T1 and T2 compared to ISS6?

Does T1 still mainly use the original tracks and components layout, or was it entirely redone?

Never mind, I eventually found the info here: http://www.theqlforum.com/viewtopic.php?t=3048

As you've found - most of the changes are documented there - the reset switch is no longer the 2 part switch used by the original QL, but takes a standard footprint momentary switch with 6 pad layout.

Checking out what components left for my repro Tetroid Iss6 in service manual...
L3 & L5 have not reference at all on it.
Only in the Schema. Based on Schema:
L5 = 22uH
L3 = 22uH

But... no idea what other electrical or any other attb they should keep.

L5 needs to be a large 1 or 2 W inductor as it's in the 9v feed for the Microdrives and is there to prevent noise being passed through the supply. It should be rated for at least 1 Amp

L3 can be a lower power - 1/4 W inductor - it's used in the PAL video encoder chip circuit.

Both components should be axial types with leads.

Thank you
The share the same footprint so ... I will put same type, and at least 1W (perhaps 2W if it is not too big)
