Ok been lazy lately but just to show what we did get upto a month or ago :roll:

video shows little basic, plus loading one of my tapes from a wav, the video is cut to save waiting for tape to load.
more than 90% is complete, its now getting time to finish it.

Z80 - doc'd + undoc'd + retrig ints if poss scope needed

TMS9929 - M1, M2, M3, Sprites, Collision

Z80CTC - IM2, ch0,ch1,ch2,ch3, Inputs: VDP, divided sys clock, tape

76489A - need to make timing more accurate / better sync

Up to 512k

Note: Seems the playback on 2 different computers give diff results, 1 is clean the other has broken lines where its decompressing the image blocks in flash
