Indivision ECS problem

source · 04 December 2009, 04:12

I have been doing some work with my A2000
1 - put in a pull up resistor to bring to V4.5 from 4.4
2 - the cap near paula was moved to make room for the Indivision ECS
3 - replaced the keyboard connector.
4 - added 2 36 pin ISA edge connectors to bring the 2 8 bit slots to 16 bit.

I installed the Indivision ECS today, and have noticed a problem with the video. The Indivision title screen appears normally, then when it comes to the 3.1 ROM screen, the video has vertical lines that missing approx 1 cm apart. When I boot up to workbench, instead of getting a grey screen, It comes up with a yellow screen again with the vertical lines. Could this be a cap problem by the video slot??

If the lines do not appear on your standard video out then it could be a fault with the Indivision. A broken RAM location / address or something?

Additionally, I see you have serious bleeding issue (check out triple or more shaddows on Amiga logo).
In fact, I have it also on my Indivision ECS.

I'm wondering if that's a grounding or crosstalk interference.
