Default Re: Mk14 vdu

It has been a very long time since I really played with the VDU and did everything which could be done with it, so I thought I had better check that connecting TOP PAGE -> GRAPH/CHAR actually does work as I remembered it did.

This is an off screen shot of a mock-up (I stress, a mock-up) of a 'graphic' version of Moon Lander which would feature a changing 'view out of the porthole' on the upper half of the screen and the essential 'instrument' readouts as text on the lower half of the screen.

All I've done here is prepare a half screen of text data and a half screen image and loaded them into 0200-02FF and 0300-03FF respectively, then linked TOP PAGE to GRAPH/CHAR as well as the PS1 input which it was already connected to.

This is just to verify that the split graphics / text feature really does work on the original VDU.
