Re Starblaze, someone left the following comment on the video:

"I suspect the game display doesn't work because it's already driving the LCD 
controller at close to its maximum bandwidth at 2.5MHz."

Does anyone know if this is indeed the case? I would've thought other things 
would've broken as well, but everything else I've tried runs normally. Unless 
Starblaze is doing something to refresh the display more quickly than other 
games/apps?

Even at the normal clock rates the TS-DOS timing issues can cause lock ups. In 
normal use one might only stumble on this occasionally. I noticed this testing 
Backpack drives when I’m doing a lot of the same operations over and over again.

It seems to stem around pressing the next button you want before it is down 
drawing the screen. If I don’t get in a hurry and wait for a second after each 
screen is drawn it never locks up. I suspect that the faster clock exacerbates 
this latent bug.

Ken ,

What a great job you've done!  Thank you sir.

You really did a nice job with the assembly and commentary on how to install it.

At some point I have to find out why Starblaze video is broken....

I'm adding the upgrade to all my machines to try and get as much experience 
with it as possible.



I have noticed that TSDOS sometimes does not work in 5MHz mode, whereas Teeny 
does.  So that has to be a software and timing issue to sort out.



Thanks again Ken!  Cheers Steve
