m82 system modifications

Post by Gilrim »

I've been searching the net up and down for any and all information regarding the display unit of the original NES. The information gathered from various sources, have turned out to be rather poor and lacking.

So, the deal is the following: I've got a M82. The unit's got plenty of games (9-10 games or such), and the unit is working. -ish. See, the M82's got a knob on the back where the store supervisor or such is supposed to choose between 30 secs, 3 minutes, 6 minutes or 120 minutes. That knob is broken. so the console is stuck at 30 sec 'game play', then reboots and shows the game-list.

Ideally, I'd disable the reboot sequence al together. I realize this might be hard/impossible to do without major changes to the system, but any pointers in this direction would be greatly appreciated.

hmmm... I hooked up the thing last night to check it out again (it's been on a self for some time ;)), and it turns out the switch it working just fine :P

But it would be really nice to have some way of disabeling the timer alltogether. I've considering trying to short other combinations than the four used (my thougts are something along the lines of "well, there's five pins and four options, one is bound to be earth"). Possibly just removing the connector altogether and see what happens. This sounds like a sensible approach?

I got it from a shady aquintance, who claims "he bought it" from a store. In other words, I suspect I've bought a unit, stolen at a store.

Anyways, what I'd suggest if you want one, would be to call round to toystores that've been in the same location for the last 20 yrs or so. Maybe, just maybe, you'll be lucky enough, they've stuffed the thing way back in storage collecting dust.
