Schaltpläne für den JU+TE Computer, auch genannt TINY

Für den Minimalbetrieb sind ein Speichermodul (Typ A, B oder C) und eine Tastatur erforderlich.

Die mögliche Bildschirmauflösung und die nutzbare Farbtiefe hängt vom Speicherausbau ab:

Speichermodule | Video-RAM | Auflösung | Farbtiefe -------------- | --------: | :-------: | --------- 1 | 8 kByte | 320x192 | s/w 2 | 16 kByte | 640x192 | s/w 4 | 32 kByte | 320x192 | 16 Farben 4 | 32 kByte | 640x192 | 8 Farben
