-
- Unior
-
- 2009-05-12 Skeleton driver.
- 2013-10-09 Added DMA and CRTC
- 2013-10-11 Added PPI, PIT, UART, sound
-
- Some info obtained from EMU-80.
- The schematic is difficult to read, and some code is guesswork.
-
-The monitor will only allow certain characters to be typed, thus the
-modifier keys appear to do nothing. There is no need to use the enter
-key; using spacebar and the correct parameters is enough.
-
-If you press Shift, indicators for numlock and capslock will appear.
-
-Monitor commands:
-C
-D - hex dump
-E - save
-F
-G
-H - set register
-I - load
-J - modify memory
-K
-L - list registers
-M
-
-ToDo:
-- Cassette
-- Colour
