    Hiya,

     

    Just a quick update. Things are progressing more slowly than I would like. Current job doesn't give me the amount of free time as I used to have. I hope to have a more positive update in a couple of weeks or so.

     

    Cheers

    No worries, we know you'll get there!

     

  2. VME was super common for Motorola 680x0 based industrial and scientific embedded systems (and PowerPC later on). They didn't have to reinvent the wheel, and theoretically, could leverage cards from other systems.

    Very old thread but I am adding this link as it seems to be a solution to the problem discussed here. At this time I have no idea if the solution described at this link is still available or not.  If anyone knows please share. 

     

    Quoted from the link:

    TenoxVGA ECL to VGA Adapter (ECL2VGA)

    TenoxVGA is an adapter that lets you use a standard LCD flat panel or a CRT monitor with Atari TT built-in video card in TT-HIGH mode (1280x960). You can think of it as TTM194 or TTM195 monitor replacement or ECL to VGA video signal converter.

    Legacy Pixels is me, and I do still have these available

     

    Thanks!

    Yeah, I did same thing when I released the boxed rotary controllers. I quietly made everything without announcing it. After I had a few dozen made, I posted a thread. I did not want to say anything before hand because I was unsure when/if I would finish. It did take a financial commitment, but if something happened I was the only one out any money. Life has a way of tossing hurdles in your path.

    This is "the way"

    Over at Legacy Pixels, we don't take any payment until there is an item tested and ready to ship.

    Oddly enough, I have had people get upset that I wouldn't accept a pre-order...

    The FAQ says a 2 might work but hasn't been extensively tested.

     

    The Pi2's aren't that much weaker than Pi3's, so I'd be shocked if it really wasn't able to handle the task.

    A later model 2 might be OK overclocked (they switched to the 64 bit SoC for later 2's)

    This says it needs a pi3,   I thought I saw someone running it on a pi zero in another thread?

     

    just curious because I have a spare pi2 laying around and this would be a perfect use for it.  

    A pi 2 won't do it.

     

    You need a pi3 or 4 (a or b) or a pi Zero 2

    On PC, you would plug in more memory, and if it wasn't available or didn't work, you would get a memory manager software package from your local supermarket/computer store, and suddenly everything would work. (Or the hobbyist geek might choose to do EMM386.) Either way there were several options to get going.

     

    Yeah, no.

    Recall that the 1st meg (plus 64K) on a PC (real mode) was fundamentally different from any other memory, and the only place you can run executables. Most often, the challenge was freeing up enough of that space for the program under consideration. Memory managers handled mapping the above 1 meg ram so that programs could access it (really just horrible bank switching or copying...) . They also exploited 'empty' spaces above 640k, but below 1 meg, for small things like mouse drivers. It wasn't plug and play, and it wasn't a lot of fun. For a challenge, get Doom running under DOS on a 4 meg machine, oh, and you'll need Lantastic to support your ArcNet cards.....

     

    Better than chip, fast, slow, whatever? Probably, but it wasn't "just run this magic program and it will all work" either. 

     

    Full disclosure, I came from 6502 and 68K, and you'll never convince me that segmented memory is anything other than an abomination unto mankind ?

    I remember having to learn about and choose from the 6 different memory models that Borland C supported... 'fun' times.....

  8. Bit of an oddball thing to check (since the symptoms aren't the norm):

    Roalnd in their infinite wisdom has the DC in jack wired as center negative, where most of the sane world has center positive. I've repaired quite a bit of Roland stuff where someone has plugged in a center pos adapter. Normally that takes out the protection diode and that's all, sometimes it is worse. Is the adapter the correct one for the MT-32?
