$define{doc_title}{Errata}$ $include{"Book.h"}$ # Errata The following errata apply to $doc_product$ $doc_ver$: * 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.
