Here is a pic of the top silk layer with all the location markings and values.

Parts list and locations

Capacitors

C1 10 25v small green bulb
C6 471 flat brown
C14 *7501 brown bulb
C16 & C18 221 flat brown x2
C19 22uf 50v electrolytic can
All other C positions: 104 tantalum cap x12

Resistors

R4 & R10 Brown Black Brown 100 ohms x2
R9 Brown Black Red 1k
All other R positions: Brown Black Orange 10k x7

Other

Q1 2N3904 Transistor (Not needed for IIgs version)
DDT1 DM74S287N
DDT2 DM74S571N

Questions

Is there a build instructions somewhere? The technical folder includes photo of a required wire... This should be called out elsewhere somehow because I had no idea it was necessary from looking at the main wiki page.

 ==Questions==
-) I received a large green capacitor with markings 2A104J but I have no idea where it should go as I don't see this in the photo.
+Is there a build instructions somewhere? The technical folder includes photo of a required wire... This should be called out elsewhere somehow because I had no idea it was necessary from looking at the main wiki page.
-) Please confirm these as the photo is not clear:
-C1: 10 25v small green bulb
-C14: *7501 brown bulb
-) The photo shows transistor, but I did not receive one in my kit. What is the part number of this?
-) WRT the socket at B1. Is the top left pin, connected to second pin by a trace on the back of the board?
