Transporter the Rescue
Bally, 1989Can anyone tell me if you use L3 CPU ROMs at U26 & U27 that are 27C512 chips, do any jumpers need to be modified? I believe I'd be looking closer at J2/J3. I'm just not certain which should be jumped or if both should be left open.
If I'm mistaken that it's not J2/3, any advice would be appreciated.
Thanks
Rick
If you have 512 chips they are doubled/quadrupled up. U26 is a 128 and u27 is a 256. No system 11 uses 512 chips. Lots of incorrect dumps out there.
On the plus side 512 will work if the image on them is doubled correctly without changing stock jumpers.
Transporter would almost fit in a 256 it's got a lot of empty space in it.
Quoted from slochar:No system 11 uses 512 chips.
System 11C games use 512 sized chips on the sound board, just not the CPU.
Quoted from slochar:Lots of incorrect dumps out there.
That's a shame. I guess folks just weren't paying attention.
