    Default Mindset goes for $$$

    I'm consistently surprised at what these go for...

    Meanwhile I have one but cannot use it, since the designers *had* to put the power button on the keyboard.

    I'm not sure I can criticize that selling price at all because, well, I have no idea how it was arrived at. The Mindset was a neat machine that also happened to be an utter commercial flop, so... it's certainly "rare"?

    Probably the thing I remember Mindset most for was the ads from one of those electronics liquidator companies (DAK?) selling them off for pennies on the dollar as "PC Compatibles", which is an optimistic way of describing them.

    Yeah, it was such a pain to mod my USB keyboard adapter to disable that power button when I hook them up to my Gaming Rig...

    Just Kidding.

    I take it that it's a case of hard to find keyboards for these things? I really hate systems where they required the accessory like with the PS/1 that put the PC power button on the CRT or the adam that had the power supply for the entire system inside the printer.

    Yeah I've never seen a Mindset keyboard come up, ever. I've been trying to figure put how to jury rig the PSU and start without it.. but haven't quite figured it out.

    I would even just like to see a youtube video of one operating. I'm really curious about the graphics, Lumena, etc. I've only ever seen one video.. but it is just a demo video made using a Mindset.

    Kind of funny it went for best offer but only 1 bid?

    Looks mint (because nobody ever used them) and complete with some options so the price doesn't seem too bad except for not knowing if it powers up and works.

    I suspect it doesn't. The Mindset PSUs are weak 65w units that apparently have a reputation for going up in smoke.

    MAME dev team is working on emulating it, recent 0.211 release has preliminary support.

    The power system in the Mindset is convoluted. Power is supplied to a microcontroller on the cpu board and the keyboard microcontroller
    any time the unit is plugged in. The power switch is sensed by the keyboard microcontroller and sends a message to the system microcontroller, which closes a relay to power
    up the rest of the logic. It sends a different message when the switch is turned off.
    We also discovered most of the Mindset application disks are copy protected, expecting a sector in track 41 with a particular high
    value of sector number there which varies between apps.

    If someone has the Mindset GW-BASIC manual, we're looking for documentation on the commands MS added for Mindset support.

    I'm just surprised for all the interest, no one has posted a video of one operating, apart from that one showing off it's animation skills. I'll probably never find a keyboard for mine... I'm really curious to see what it can do in a more general context. You know.. sights and sounds kinda thing.
