Page 3: Introduction
PC), the SBC provides a basic self-contained R65X1Q system. The SBC’s ROM implementation is compatible with Glitch Works ROMFS, which allows for the storage of file records in ROM. These records can be loaded from the monitor, or automatically selected by option switches on reset/power-up. -
Page 4: Configuring Console Speed
The UART bitrate is divided from the main system clock using one of the onboard counters. ROM images provided by Glitch Works, LLC use SW2 positions 3 and 4 to select the bitrate used for the ROM monitor or other startup routines. The following table describes the possible configurations... -
Page 5: Glitchbus Expansion
Glitchbus Expansion The R65X1Q SBC is expandable through a Glitchbus expansion header. Glitchbus is a generic 8-bit bus intended to be processor-agnostic. As implemented on the R65X1Q SBC, the Glitchbus can stack above or below the SBC using PC/104 style stacking headers. The R65X1Q SBC can also be used with right-angle headers and a Glitchbus backplane. -
