RC80 PROPIO V1.1

V1.1 Board 264 Connections 12 VIAS

UPDATE: Testing completed. The card works GREAT using RomWBW code. See attachments for config info & PIC.

• Testing using SC126 z180 Board (https://smallcomputercentral.wordpress.com/sc126-z180-motherboard-rc2014/)
• See Attached for changes to ..\RomWBW\Source\HBIOS\Config\SCZ180_126.asm to add RC80-PROPIO support
• PRP (RC80-PROPIO) default IO Base address is set to A8h
• Edit ..\RomWBW\Source\HBIOS\prp.asm to change IO Base address (PRP_IOBASE .EQU $A8)

Objective: Migrate the PropIO 2.01 board to RC2014 environment utilizing a "bus compatible" RC80 bus.

The baseline "parent" design and the relevant Propeller Firmware can be found here: https://www.retrobrewcomputers.org/doku.php?id=boards:ecb:propio:start

And the baseline "parent" design derives software support from here: https://www.retrobrewcomputers.org/doku.php?id=software:firmwareos:romwbw:start

Many thanks to Wayne Warthen (PropIO 2.01) and the other original designers!

Thank-You Jim (trawlergeek) for migrating this board from Wayne Warthen original "ECB" RetroBrew Design

2020/07/11 - created first attempt at routing the board.

• It is crowded 100mm x 75mm so far.
• Standard RC2014 is about 100 x 49. We are not constrained to that profile.
