Playing the revolution/Home Computer Invasion Documentaries in Trouble???

Original Link being gone, it makes me fear the worse.
I REALLY hope the reason isn't because of damn lawyers!

Here are two other sources for the Teasers on the most thrilling documentary series since The machine that Changed the World:








There's never been a computer documentary this well shot EVER, and nearly everyone I respect and admire in the industry took time to get interviewed. I really don't want this to be shelved.

(SAFE) US SMS Japanese Mod in action



Charles MacDonald provided a circuit for me to try
HERE

Good news is that it now works after a few treaks.
Just have to to a proper protoboard version now.

I'll be receiving two different FM Units soon, the original and the "Australian Reproduction"

The reluctant US SMS that didnt want to be japanese

EDIT2: A new solution (much more invovled ) was suggested by Charles MacDonald this will be interresting to try.

EDIT: Nice, I got my answers in that thread. I'll have to backtrack on when did this become a dangerous thing to try, FYIW I used 10k res to short pin 34.

This MOD does not work on my SMS:

















I tried everything, including burning a Japanese BIOS which works great here:


















While its cute and all (especially with my RGB mod to a Commodore 1084), I still don't get the mark III boot on my Wonderboy 1/2/3 carts when I ground pin 34 on 315-5216.

Another user is getting the exact same prob with this motherboard rev.

Any takes?

Does ... not ... compute...







Added Internal Picture:





Theres a piezo in there... now if I could
make it beep.....






Horrible damage due to the leaking internal soldered 2x1.5v AA batteries (removed)

The Great AdLib Fire ...


(see third capacitor from bottom) ...  I hate that smell.

From wikipedia:

"Self-destruction and thermal runaway

Tantalum capacitors are under some conditions prone to self-destruction by thermal runaway. The capacitor typically consists of a sintered tantalum sponge acting as the anode, a manganese dioxide cathode, and a dielectric layer of tantalum pentoxide created on the tantalum sponge surface by anodizing. The tantalum oxide layer may have weak spots that undergo dielectric breakdown during a voltage spike. The tantalum then comes to direct contact with manganese dioxide and the leakage current causes a local heating; a chemical reaction then produces manganese(III) oxide and regenerates (self-heals) the tantalum oxide layer.
However, if the energy dissipated at the failure point is high enough, a self-sustaining exothermic reaction may occur, similar to the thermite reaction, with tantalum as fuel and manganese dioxide as oxidizer. This can destroy the capacitor and occasionally produces smoke and possibly flame.[3] To prevent catastrophic thermal runaway failure, auxiliary protective devices (e.g. thermal fuses, circuit breakers) may be used to limit fault currents"


Oh the joy, guess ill have to replace them and retry .. with the windows fully opened... no lets make it OUTSIDE!
