RomWBW Errata

The use of high density floppy disks requires a CPU speed of 8 MHz or greater.

The PropIO support is based on RomWBW specific firmware. Be sure to program/update your PropIO firmware with the corresponding firmware image provided in the Binary directory of the RomWBW distribution.

Reading bytes from the video memory of the VDU board (not Color VDU) appears to be problematic. This is only an issue when the driver needs to scroll a portion of the screen which is done by applications such as WordStar or ZDE. You are likely to see screen corruption in this case.
