The MTX on Youtube

Post by Martin A »

This UK Computer museum/retro youtube channel "The Cave" has released a new video that includes a quick test of a couple of donated MTXs

The 500 worked, the 512 back screened.

What's interesting is there's a quick view of a computer listing

I don't think I've seen any regular MTX add-ons using ports 128 and 129. Anyone got any ideas ??

It's doing some strange things. The peripheral seems to be 16 bit in that it's loading values from ports 128 and 129 into HL, then it's comparing, looping until a value is the same as L.

I wonder what the heck it's doing.

We should ask Neil for a scan of the complete listing. It might not happen immediately, but worthwhile, no?
