Your H4 needs a better name.
If it ain't broke, test it to Destruction.

Working on the booster part now..

Was supposed to be this...

but ended up like this...

IMG_5117.JPG

.. Basically because there was one bent pin, and by the time I got the CPU out of the socket.. Broke the socket.. Ended up with more bent pins... Ripped a couple of tracks up on the PCB... I ended up just stacking sockets and putting my ZIF adapter in as had enough of those DIP's!

So we ended up with this...

And later on this...

I don't know if this will work with ultrasatan... I really cannot be bothered at this point to start messing around with it all... I do not expect there to be any issues but you never know with all this stuff :roll:


Anyway, the blitter test has just finished..

A accelerator like the terrible fire ones can be plugged into this board.. The board is just used as a TOS206 decoder. of course with correct firmware on the terrible fire boards, the effective ROM speed can be up to 32MHz.

So the booster is been a bit of a pain, I don't know why :roll: It is very hit and miss if turning on the computer boots up, I did think at first this could be a wake up state issue, but pressing reset several times generally lets it boot up..

And not really sure why this is happening yet. It is possible it is because I had to scrimp on IO pins on the PLD as I didn't have enough pins for a RESET signal to it :( But even so I don't really know why this would be a problem anyway.

Nothing seems to be wrong with anything. Through the CPU clock is pretty bad which I think isn't helping. So buffer and other bits added in... will "retire" the current boards to TOS206 only boards while the waiting on the new boards....
