Is anyone using the full 25 pin serial port for anything now a days? Could we make it 9 pin and put it to either ends and get the space that is left over for switches/outlets? Or has that already been considered?
Its been talked about a lot in the past.. It would save space, but there would be nothing to really go there anyway ? Things like LAN would be under the PSU as that is where the main chips are.and more free space.

Just checking - at least one 9 pin serial port will still be included, right?
Thanks.

Nothing has changed on that. Still a normal 25 pin on the back. I was just sparking an idea.

Okay, thanks. I'd be good with either the 9 pin or 25 pin, just as long as there's a
serial port. :)

Though I hope once we get the cores running on CPU & RAM can run at 32MHz and with our FPGA shifter by @Smonson , we are already ready for higher resolutions and colours. We just need faster RAM, and the suska cores in FPGA opens up this door!
A theory - if you're running an FPGA MMU and shifter, then you may be able to increase the resolution/colour depth without faster RAM by widening the data path between the RAM and shifter from 16 to 32 data lines or even more.

Yeah that's been a goal mixed in with the 020 CPU.

And make everything 32-bit? Yeah, that would make it simpler, I guess!

Might as well go the whole hog and build a fully 32 bit machine from the ground up with a 68000 in there for game compatability. There seem to be lots of cheap QFP 68030s on Chinese web sites to throw in there. TT clone anyone? :D :lol:

I've locked this tread as it's got off-topic and giving the impression the H6 will be 32bit when we are a long way away from that.
