Hi,

I am looking for Elevator Action bottom MCU board (68705 MCU is labelled BA3 11), as it is missing in my game board set. If you own it as spare,let me know. Smile


Thanx in advance.

Maybe you are not on MAME Dumping Union list like me but internal ROM of this 68705P3 MCU (as well as the ones of other Taito SJ games) has been dumped last year using a special device.So, get a 68705P3 MCU and program is with dump.But I warned you that this kind of MCU is very hard to come by and expensive.

Indeed, 68705 MCU is not supported by most of programmers. In fact, I was informed when MCU internal rom of the japanese version of Renegade (Technos) has been dumped.

Thanx for the reply, and keep up the good work !

Isn't there a rom set that works without the mcu pcb? It's been a while since I messed with an Elevator Action pcb so I could be remembering wrong.

It seems MCU protection has been patched in the boots and converts of EA roms.
