Definitions
- go
- Fetch address from RIGHT and send back two words from this address. Jump back to go.
- init
- Set register B, and jump to go.
Description
This node contains the second part of character bitmaps. Each character is stored as two 18-bit words, in little-endian order. Format of these two words is following:
| 3 | 3 | 3 | 4 | 4 | 4 | 4 | 4 | 5 | 5 | 5 | 5 | 5 | 6 | 6 | 6 | 6 | 6 |
| d | 0 | 0 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 2 | 2 | 2 | 2 | 2 | 3 | 3 |
- d
- Descender bit. If set, the whole bitmap is shifted two double scan lines down.
- nnnnn
- Five bits of each slice. Slices are numbered from the top of the character matrix.
The address of a bitmap supplied by node 514 has bit 6 set, but due to RAM mirroring it is irrelevant. Thus, character with code 27 (letter q) is located at address 40, which is actually the beginning of RAM.
