STe booster v 1.5 36Mhz

Hi,
I am install dma chip from board without externall blitter to board with external blitter and all working fine :-)) wire for clock booster is koaxial 50ohm without termination. All test ok . Super...

Great well done!

Neverending story.

Problem - 32 Mhz with tos 2.06 and blitter,
and this blitter warm up to about 25 Celsius - when I move with the window - screen is damage.
when i cooled the bliter with cool finger screen is OK.
On 8 mhz is all OK.
And strangely is: in Tos 1.62 it doesn't happen, only in Tos 2.06
i will istall peltier article and everything will be ok :-) is joke

any idea?
another blitter chip ?
thanks

Possible could be blitter is not happy.

Though all these problems is basically why I just stopped making booster for STE, because they are just never ending trouble on some machines.

Hi
resistor p100 has 2.2kohm, can i try replace resistor for 1.2k, or cut power line to blitter and add to series diode to low voltage, what do you thing about this
thanks

You could try it.

or cut power line to blitter and add to series diode to low voltage, what do you thing about this

Nothing I ever tried or needed to do. So I really can't comment.

Hi, gut news. I replace blitter and works. :D

Great work! I need to get started with mine to get it working. Just installed it when I bought it but never got a screen.

Another Atari, a STfm I was working on, also didn't show a screen. Turns out that I have some problem with a hdmi cable, OSSC, flatscreen or/and scartcable. Display sometimes. *sigh* So it seems that it wasn't the STe fault.

Is your running at 32MHz or 36MHz now?

I'am running on 32MHz, clock from motherboard.
