Description

CAUTION! UNTESTED - WORK IN PROGRESS - UNDER CONSTRUCTION

UPDATE V1.1 Board 369 Connections 50 VIAS

V1.0 TESTED & WORKING with: ECB to SC126 BUT the 3 Sockets are inverted

ECB-PROPIO - https://www.retrobrewcomputers.org/doku.php?id=boards:ecb:propio:start

ECB_VGA3 - https://www.retrobrewcomputers.org/doku.php?id=boards:ecb:vga3:vga3

Retro Brew ECB to RC2014 RC80 MB

The idea is to allow the testing of ECB boards on a RC2014 system or RC2014 boards on a ECB system

I have successfully tested it connected to a SC126 using RomWBW Dev Version 3.1 Pre-release.

I was able to connect a ECB-PROPIO and use it as a VGA Console with PS/2 Keyboard and SD drive. (Card I/O Address A8h)

I was able to connect a ECB-VGA3 and use it as a VGA Card with Keyboard. (Card I/O Address A0h)

See the attached SCZ180_126PV.asm (RomWBW-dev\Source\HBIOS\Config\SCZ180_126PV.asm)

See the attached vga.asm (RomWBW-dev\Source\HBIOS\vga.asm)

The ROM used for testing is attached (SCZ180_126pv.rom)
