Well, that is funny, as the signal obviously didn't overdrive the monitor before it was fixed (and hooking it to my C64 will produce the same effect, screen scrolls on light border colour). > There are several versions of these cards. Frankly, I'm not sure what the manufactorer of my expansion memory is, as I received it without the plastic encasing.

Although, for a short while, I managed to get the 16K section working by pushing the card upwards or something, which I would believe is a sign of poor connectors. I was hoping someone on this list would tell me I could apply some liquid metal or something and get the pins as good as new again.. ;-) Regarding Modem's pokes, I never tried that non-interlace poke, but I always believed that was something that only applied to NTSC VIC (and as I said above, the combo worked fine before). /Anders Carlsson - This message was sent through the cbm-hackers mailing list.
