Before dismantling my donor machine, I did a series of shots like i did for my STE. Two big capacitors was hiding other components or marking, I had to make some close-up shots for them.

Anyway it should help spotting some of the components and their values.

Couple of quick shots from the STF I picked up in the last week. I've since cleaned the case, but the board itself came pretty clean! Probably no more detailed photos are necessary, unless there's merit in taking them.

Mainly noticed on mine that one of the TOS 1.0 ROMs has been swapped out at some point?

Also, I'm curious: the chunky capacitor around JP4/5 and the RAM banks is hooked up differently on some boards. Why?
