Prototype / development adapters
r12:
Model "r12" 17.50 € / 1.
Cables not included.
Due to thickness of package, shipping in maxi letter. 12.50 € Europe, 20 € World. Up to 250 grams. (Many pcs at same shipping cost)
Notes:
If you needed series capacitors on any signal line, well this adapter doesn't have them.
330 ohms on composite sync, 75 ohms to 5V on select RGB fast blank. Select 4:3 line has 12 volts via 1 kohm (also a jumper.)
Grounds connected together except audio ground, which wired separately to RCA connectors.
(A1200 has separate video ground that connects to main Amiga ground with ferrite beads.)
If there are substantial ground level differences between devices/TV antenna, don't use this or at least do not touch metal parts when handling, to avoid electric shock.
Model "r15" has top side RCA connector.
Maybe for A2000, which has video connector at one side. RCA lead connectors block power cable in A500. Block motherboard RCA connectors in A600 and A1200, unless the connectors in RCA cable are very short. (Pictures)
Price 17.50€ (includes flux residue from solder wire)
Shipping 3.65€ Europe
RGB return grounds wired separately to D23 pins, which are video ground in A1200, in most Amigas common ground.
