Hi!
First of all, I apologize if this is not the right place to post this kind of subject. But from all the sections it appears to me the most adequate.
I've got a darts machine that was working well until one day that it stop doing one simple rule - finish the actual game by rounds.
It is supposed to finish the game after the round "X" but it stoped doing that and the game went in infinity mode!
Everything else is working normally.
The electronic board have some ICs that I belive the problem is. I've done this roundup of them:
IC 01 = Z8018010VSC (Processor)
IC 02 = IC 09 = IC 10 = IC 11 = SN74LS273N (OCTAL D-TYPE FLIP-FLOP WITH CLEAR)
IC 03 = I didn't removed the sticker yet, but I belive it's a programmable Chip
IC 04 = IC 05 = PALCE16V8H-25 (EE CMOS Zero-Power 20-Pin Universal Programmable Array Logic)
IC 06 = TDA2003 (monolithic audio power amplifier integrated circuit)
IC 07 = DS1225Y - 150 (64k Nonvolatile SRAM)
IC 08 = H606014 (Watchdog_timer)
IC 12 = TD62083AP (8CH DARLINGTON SINK DRIVER)
IC 13 = IC 14 = IC 15 = IC 16 = SN74HC244N (OCTAL BUFFERS AND LINE DRIVERS WITH 3-STATE OUTPUTS)
.
I wonder if any of you, with much more electronic experience than me, have some ideia here this problem can possibly be.
On the top of my ignorance, I have already ordered two SN74LS273N to see if the problem is on that flip flop IC.
I belive that the problem can also be in the programable chips and if that is the case I have to find some machine equal to mine to get those ROMs.
Once again sorry if this is not the right place and thank you so much for any kind of help on this!
