Nice to see the game is almost playable! One step further dude

yeah, let's see what happens after that ? any input on the speech issue?

[baritonomarchetto]

I had no problems with mine (on the speech side, at least), so ATM i cannot be of "fast" help

just got back from another J2 test round:

- battery voltage still holding steady
- all the rom / rom / cmos tests are passed successfully

however: the sound test cycles through 15 different sounds, but only sounds 1 - 4 can be heard, sounds 5 - 15 stay silent

i don't know if J2 uses an individual chip for both sound and speech, but there seems to be a problem somewhere somehow!

Ully, as far as I remember, I had a piece of paper under the battery until I delivered it to your place. Did you by any chance put it back in the anti-static bag I brought it in ? This could have shorted the battery terminals and thus drawn the battery.

you remember correctly, the paper piece was still there. i simply pulled it out when the resto was finished and never did anything else. what exactly should / could / might i have put back in the anti-static bag? the whole pcb?

[level42]

Yeah..if the PCB would have been back in the bag without the little paper isolating the battery it could drain because of the conductive inside of the bag.

[Superully]

nope, that i didn't do! i removed the paper slip right before my tests.

Ully was here tonight and I replaced D2 with a Schottky diode so it "eats up" much less energy (voltage drop was now 0,01V instead of about 0,4V with the old diode. This should improve the battery draining dramatically.

I had to improvise the soldering (cut the body of the old diode and soldered the new one to the old legs) because I didn't think I could get the old solderings removed properly on the solder side of the board.

There's no leaks or bad tracks up to the RAM that the battery supports.
