FYI, I managed to Install my B26 System overnight with BTOS 4 Images fronm Bitsavers 8-)
Amazing it still works.
yay!
barry needs the device data block dumped from the debugger in the boot rom.
"The bootstrap ROM creates a table of connected modules, stored at 0:0FC9, containing a count of modules, and the module ID returned from port 0 for each module. This is created early in the boot process, so you can go to menu mode (press Space after reset, needs good timing ;)), and you can view it in the Panel Debugger. Would be nice to see what it read from an actual system."
