In order to spare the 32K RAM of the original z88, the RES0 size vary if the machine is expanded or not.
| Font | Unexpanded | Expanded |
|---|---|---|
| Lores0 | 256 bytes, 32 UGD characters | 512 bytes, 64 UGD characters |
| Hires0 | 512 bytes, 64 pixels width map | 2K bytes, 256 pixels width map |
| SBF | 8 rows of 256 bytes (2K) | 8 rows of 256 bytes (2K) |
On an unexpanded Z88 Hires0 may actually overlap Lores0. If Map=Yes and Map size in Panel is set to more than 64 (up to 96), UGD characters may be overwritten by map information if PipeDream is run.
