Re: Issue 6 VM12 & resistors confusion

I have a spare 8049 as I recently put a Hermes chip in one of the QL's i have, so you are welcome to that if you want it. Just PM me. But I suspect the issue is more likely the keyboard matrix...

Re: Issue 6 VM12 & resistors confusion

Simple resistor diode protection on the inputs was all we used. The QL has resistors on...

Re: Various accessories for QL

I'd be interested in the mouse interface - never seen one of those particular variants - so if Chris is getting the whole bundle and sending parts on - I'd be happy to take that one if it's going? Oh, that was one of the things I would have been likely to keep, but I'm not 100% sure. When I get eve...
