[sdiy] 2N3102, 2N3415

[med]

the schematic is being hosted at
http://www.sinclairinternetwork.com/schematic.jpg temporarily...
there are resistor values scrawled across the side -- i was listing
what i needed to buy; disregard them.
it's a photocopy from a book (called 'electronic circuits manual', i
think) from the late 70's that i found in the local library; thus, i'm
not sure as to its legality.
