V1.5 booster & Blitterpatch

Post by LaoMu » Tue May 15, 2018 8:57 pm

Hi,
I am thinking about to buy a V1.5 booster and put it into my Mega ST1 with 4 MB of Ram. What is not clear for me, what
I have to do with the installed Blitterpatch. Is that obsolet together with the booster?

If you have a more "recent" blitter, then remove the patch and fix the trace under the CPU.. The patch is only needed on early blitters.

Hi,
thx for answering. I have a ST/SGS Blitter coded 8833. I assume that one do not need the patch, right?
Regarding the interrupted track....I think I just solder a small wire between the 2 points which
had been connected trough the track before.

Thanks LaoMu

It should be ok, I would remove the patch and give your machine a good try out first just to be sure.
