Default Re: Mk14 vdu

The attached is a 2048-byte file which breaks down as follows:

0000-01FF 'SCMP Inside' (Graphic image).

0200-03FF 'Clive' (Graphic image).

0400-05FF Text page consisting of the character set in ascending character code (0x00-0x3F) order, repeated 8 times to fill the whole screen.

0600-07FF Test text page, plain text.

These are intended to be rendered by the VDU as continuous 512-byte blocks, which they will be if programmed into an EPROM connected to the VDU.

The file (wrapped in a .zip for attachment here) is a raw binary (.bin) file - my very high end (but very old) programmer can load just about any hex format but will only save to raw binary. Ho Hum. However, in my experience virtually any programmers (or their support software) can load raw binary files.
