Identical problem with 2 modbos
I have just installed a v1.1 modbo into a version 4 ps2 (pal) and a v2.0 modbo into a version 6 ps2 (pal). The problem I'm having is exactly the same for both chips and is as follows: When first turned on the chip works fine but after a few minutes it stops working (as if it is not installed or disabled). If I turn it off for a while and turn it back on then it works again for another few minutes. Has anyone any idea what could possibly be wrong? I have read on here about versions >= 9 needing the H pin connected. Could thid be true for earlier versions too.
Any help would be massively appreciated. This is really doin my head in.
