Ok, going to take a break from trying to fix my Space Invaders while I try to track down a D3245 ic.
Started working on my Guided missile.
What I have done so far.
- Built up a JAMMA adaptor. Presently controls aren't wired up.
- Jumpered the board for 2716 EPROMs
- Unlike the SI and SI deluxe, I have to manually reset the CPU.
- Have burnt the new Space Invaders Test ROM to an EPROM and installed.
So this is what it does.

Petty funky stuff...but it actually looks like it's running the the Test ROM code!!!
It's the same test ROM as can be seen here: https://www.youtube.com/watch?v=J0KvcoGKL-4
...so you can see the change in pattern on my screen as if it's drawing the rows of text..'RAM, CRC ROM E, CFC ROM F' etc etc.
This all looks promising, just not sure what to make of all that scrolling stuff.
Any advice or if anyone has seen something similar, I'd love to hear from you.
Cheers
Phil
