Picasso IV Challenges - Help needed

bluewizard · 21 October 2023, 19:20

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.

Have you read here? - Lots of FAQ's.

I had not found that page. Thank you for sharing!

It did have a link to the older FlashROM but sadly that didn't make any difference.

Picasso IV's are an awesome piece of Hardware for any Big Box Amiga, but they are very finicky when being set up.

If you've had another Graphics card installed as I did many moons ago, a Re-install of my hard drive was simply the best thing to do at the time.

On the Link above in the install section, it mentions about removing all the Monitor Drivers aside from PAL & NTSC but that made no differences at all after having had a 4Mb CyberVision card set up on that particular install.

There were lots of possibilities as to why the PIV wouldn't play ball & may well have been the ModePro configuration I'd used for ages with incorrect identifiers all over the place.

You can always back up your boot Partition prior to a fresh Install of the OS & copy back over if no joy.

Have fun!

That sounds like broken hardware that blocks the bus or does some other bad things.

Same behaviour when booting the Workbench from floppy disk? If so, it's hardware-related.

Sadly even with booting with the HDSetup3.2 disks the screen redraws are painfully slow as well.

Also when I do the 2 mouse button hold down the selection page has slow redraws.

I have only installed Picasso96 software for this. 1st the free version then I registered it.
I also moved all monitors from devs except NTSC and PAL per the direction but that didn't seem to help.

With having the boot from disk doing the same thing I am not sure going through the pain of re-installing is worth it sadly.

I guess I could add it to my list to recap and see if that helps but I am really baffled.

Kinda makes me sad as it looks like an awesome card that I would love to have working.

On the sad side, it's sounding more & more like a PIV Hardware fault tbh....

Guessing you don't have another A4000 to try it in?

Do you know someone local willing to try in their A4000?

Towers are sparce but D's are readily available by comparison....

At least this would help guide you better for a possible solution.

I do have another A4000D to test it in.

This conversation has really helped and started me thinking.

I pulled the flicker fixer PLCC out again and it appears I bent some pins so they were touching. I fixed that and now everything is working great again!

Oops.

Now that is an amazing result fella.

Great to talk isn't it!
