Picasso IV challenges - Help needed.
« on: October 21, 2023, 05:45:55 PM »
Hello All,

I have a Picasso IV I am trying to get to work in my Amiga 4000T.
It works fine in RTG mode but when the NTSC flicker fixer is passed through things get really really slow to redraw and just operate.

I have a ZuluScsi 2040 in it and placed that in debug mode and I get warnings that things are taking longer than expected and get slow transfers from the ZuluScsi:

I had pulled the PLCC's out (with a puller) to deox and clean when I got it as I was getting weird lines in flicker fixer mode but it wasn't slow.  With this cleaning the lines went away but now I have slowness.

I flashed the P4Update7_5 but did the flash prior to cleaning everything.  I have tried to re-flash but it won't let me as I have 7_5 already flashed.  I have tried to find the P4Update_1_11.zip file but have been unable to find the file anywhere.

I think the boot time is now at least a factor of 10-20 times slower than without the Picasso IV installed.
I have Buster -11 chip.  The A3640 v3.1 CPU Card.  Running OS 3.2.2.1 with the V47.111 ROMS.

I am using the latest Picasso96 3.4 (purchased).

I have not been able to get the Picasso flicker fixer settings to come by holding or hitting the shift keys either.

I feel something isn't just quite right and I have some setting not right or flash wrong? 

I am open to ideas and thoughts.

Posting my fix for the record.

Apparently when I cleaned the board I accidentally bent some pins on the Flickerfixer chip so I had some touching.  I corrected that and things are working great again.

Oops.
