Compute's Mapping the 64 p216 says is the routine to setup VIC-II

Now gets to cracking screen, but doesn't accept SPACE to continue.

Calls $FF9F to scan keyboard, which we had pointing to a stub routine. Fixed to point to the real keyboard scan routine. Now SPACE is accepted, but then CPU ends up going to la la land and hitting a JAM at $0008.

Need to trace to find out how that happens.
