I’d like an 8060 based NIBL with page 2 support, any chance you would include an 8154?

I’ve used a 74act163 as address latch and was thinking the RCO output might be used as a page decode for IO at Fxxx, but maybe for a NIBL machine a 74x169 could use the RCO in count down mode to enable the 4k rom for NIBL, and disable ram if it has a second Chip select.
