ADB SoundBox to old-style keyboard?

I have a couple of NeXTstation Monos with the original style keyboards and mice. To run this, I've been using a sound board from MegaPixel display connected to a VGA monitor.

Recently, I picked up a nice SoundBox for cheap, later to realize it was an ADB variety. DOH!

Is there any adapter or easy way to replace the ADB din with the older style DIN so I can connect the OG keyboard and mouse? I can obviously put my non-ADB sound board into the SoundBox but I was hoping to have 2 NeXTs running simultaneously.

Does anyone want to trade a non-ADB sound board for an ADB sound board? :)

Thank!

Thanks Brian! Looks like the mod requires drilling holes in the soundbox or moving the board to another box. Bummer!

Yeah. At the time I did this mod Rob had a box of NOS bottom shells... what you could do is remove one of the ports from the board and use that hole to make the connections external.

If you don't want to drill the original shell, you can replace the ADB connector and transform the soundboard so that it works only with NON-ADB systems. A friend of mine (an electrician) made this change in my board, following the instructions on Brian's website.

That looks really slick! I'm pretty good with a soldering iron, but that might stress my "maker" skills to the max! ;)

Is it possible to run ADB keyboards/mice on original mono/color NeXTstations using the ADB soundbox? Maybe with a ROM revision/patch to the logic board?

THanks!

It's a chipset limitation. No firmware solution is possible for nonturbo hardware.

Hello Brian: Would it be possible to make an ADB to non adb external convertor ?

This is interesting here https://www.drakware.com/product/NeXTUSB

USB keyboard on ADB system



and we know the ADB sound card can be tricked into being dual compatible with your whammy....

distortion field lol , so the no sound sound card solution some how we would need to have a signal convertor similar

would it be possible to create a usb bridge adaptor of sorts....  ADB peripherals to USB to non adb NeXT hardware  on a no sound solution  ..... given we know the ADBsound card can be dual compatible....
the no sound card is dual compatible , man cool mod on the riser solution .

ADB has to do with power on pin 7  ..... it is their somewhere .   ADB to non ADB conversion cable with a convertor in the middle.
