Equivalent 74 series IC for a 9310 BCD Decade Counter IC used in SI boards ?
The Question:
Does anyone know what the equivalent pin for pin replacement 74 series IC is for a 9310 BCD Decade Counter IC used in SI boards
Anyone else out there have an Artic PCB that is setup for space invaders ?
Why ?
I am researching replacement or equivalent parts used in Space Invaders boards to help document parts used in a Galaxy Wars PCB (made by Artic)
I am currently documenting the PCB layout for an Artic Galaxy Wars PCB, which uses pretty much the same (if not closely matching) architecture of the Space Invaders games (apparently no accident there!), so the info is needed to work out what chips they might have used as alternatives. i am also hunting thru databooks to try and pick it too.
EDIT: Just for interest: Baz found a Cosmic Critters PCB by Artic with another AA member - exact same base board as the Galaxy Wars (no add on hack)
The PCB i am looking at has is a long thin single PCB for the CPU/eproms (although there is a small add-on hack Eprom PCB for the Galaxy Wars game) with a seperate sound board for the sounds. (not sure how closely the sep sound board mirrors the midway L shaped pcb set extra snd pcb (cocktails ?) - i'll work that out later.
Hoping one of you SI repair gurus has the answer on the tip of the tongue!
