    yeah that's the length i have now so it'd be perfect. where'd you grab them, i'd prefer local just because small purchases like this attract crap shipping a lot of the time.

    Happy to post you the 1-2 I have. Longer 40pin cables I had to source from eBay HK.

    Wanted to post this here instead of the MiSTer thread, because this is a bit more platform specific

    https://misterfpga.org/viewtopic.php?t=2227

    For those that aren't familiar, MiSTer is an FPGA system which includes a port of the "Minimig" cycle accurate Amiga core, ported over from the previous "MiST" project (also an FPGA system).

    MiSTer includes both pixel perfect analogue 15KHz video output over both RGB and component, as well as a zero-lag digital scaler spitting out video over HDMI. The scaler offers a variety of scaling options, but the best is obviously a clean integer scale (where each pixel is cleanly scaled by an even number to avoid weird, uneven blocks on scaled images). Sadly that means typically scaling by 4x and having a border on a standard 1080p monitor or TV (TVs are particularly useful as they do 1080p50 nicely).

    The thing is, a great deal of games either keep valuable information away from the edges, or for certain systems have a natural empty border anyway.

    MiSTer began offering a cropped 5x scale, and the recent Minimig core update now allows this per game, which means it doesn't have to interfere with either the OS or software and games that don't deal well with cropping. The cropping also offers the ability to change where the upper and lower cutoff is, which is great for games that have more space at the bottom than the top, or vice versa.

    There are good examples in the thread linked, but it really does make certain titles fill a 1080p screen nicely, without losing visual information.

    Of course if you have a 1200p or 1440p monitor you have more options. But for 1080p users, this is a pretty cool offering, and very customisable on a per title basis.

    Yeah, games would typically use the "lores" mode with the maximum (non-HAM) 32-slot colour palette. PAL Amigas could output 256 lines, but games typically targetted 200 lines (which was the native mode for NTSC Amigas).

    There's some light reading about it here: https://wiki.amigaos.net/wiki/Classic_Graphics_Primitives

    The Sega Master System did a very similar thing, with many titles coming in at 192 lines of viewable resolution that got thrown out to a 240/288 progressive line display. That's another system that can happily have a 5x "cropped" mode on a 1080p display and still have no loss of visual information for a stack of games.

    has anyone else been watching the RMC T2T series on the CDTV? I particularly like how he tracked down and interviewed some of the Commodore staffers.

    I'm wondering where this one will end up - I need to pull mine down and get the CD drive working properly but it's quite a time consuming pull down.

    The fact his CD drive was repaired through faulty caps and moreso the symptoms of the caps was very cool to me. People often don't appreciate (well some people) just what faulty caps can be doing to their machines. See part 2 and around 15mins in where Mark takes over and does some electronicsing.

    So the next Amiga meetup is next week here in Brissie and one of the guys is making RGB2HDMI's to bring along (he's also flogging them off through Amiga FB groups) here's a pic of one of his units installed posted by a member, i'm dragging my A500 to the meet to grab one and have a play - i will finally be getting on the RPI bandwagon it seems.

    I was attempting to be humorous. You get on Reddit/Twitter and talk about old games, and all you get is "just buy a Pi". Quite tedious.

    How much?
    So this just converts the signal to HDMI format?
    Easy to do?

    If anyone's eager to build one, I've got a few (5) spare board+component sets due to minimum component orders, I just need to figure out what to charge for them (planning to sell at cost). The one I've assembled so far works (it was my first time soldering SMT ICs, so that's a win), but there's no way I can sell assembled boards.

    A friend is telling me I should get a vampire...
    Should I?
    Then I wouldn't need one of the RGB2HDMI ?
