C128 MIOS Project

[Guest tub]

Just thought i'd post my prototype plans for my midibox, i'm planning to use the case from the Commodore 128 (i'm stealing the sid chip out of it for a later project ;))

Whacha think? i'm going to use the original power supply and the same power led...

ps,

1. do the menu buttons come from the DIN module or from somewhere else? Not too clear on the diagrams.

2. does anyone know if it's possible to get serial _and_ midi connections working at the same time?

Cheers.

Hi Tub,

1: the menu navigation for common MIDIboxes requires 4 buttons, sure they are connected to a DIN module. You should also add some additional buttons to handle with "special button events", e.g. to quickly change into a submenu or to select another bank. Also additional LEDs above or below the buttons could be usefull which show the status (e.g. if you are using Bank Select buttons, to show the selected bank, or if you are using a Shift button with hold function, to show if the first or second layer is active). They are also useful to control your sequencer via remote (e.g. Play/Stop/Rew/FFwd/Rec button)

I would suggest at least 12 additional buttons + LEDs (LEDs are not required for the menu navigation buttons)

2: not without a second microcontroller and a special firmware which communicates with the MIOS core (e.g. via IIC).

Best Regards, Thorsten.

Thanks for the reply TK, i've been following your projects for about 3 years (ish) now... it amazes me whenever i come back :)

Thanks for the pointers, time to get back to photoshop methinks...
