💻 Indivision AGA Mk3

Now I've finished with my A600 tinkering I've turned my attention back to my A1200. I wasn't in the market to replace my Mk1, but while hunting for a solution to my A600 monitor woes (see previous post about the OSSC) I spotted the Mk3, and jumped on it. It turned up a few weeks ago, and I've finally got around to playing with it.

It's a different beast to the mk1, coming in two parts; one for the CIA and one for the Lisa, both of which seated with a very satisfying click. This is already an improvement over the Mk1, as mine was forever falling off, or needing a firm push to jiggle back into life.

The HDMI output is asbolutely crystal clear. Having been using the OSSC for the last couple of months I wasn't expecting to notice much difference, but the picture is pin-sharp, with no overscan.

My monitor doesn't have speakers, but it should be possible to route the Amiga's audio over the HDMI, which I'm keen to try. At some point during lockdown I'll grab the OLED downstairs and give it a go.

The Mk3 seems to have picked up my monitor's supported modes over EDID with no problems. HighGFX and SuperPlus work like a charm, but I've not tried making any custom 50hz modes. Once I've bounced it up to 3.1.4 I'll dig into that a little bit more.

My only complaint, so far, is that the HDMI adaptor doesn't fit anywhere sensible on my tower case. It's designed to be screwed into the plastic case of a stock A1200, so I have to have it dangling out the back of my case. Far from ideal...

So yeah, inital impressions are extremely positive. It's not cheap, but I was able to insta-sell the Mk1 and cover 2/3s of the price, so at least it'll hold its value ;)
