Design, documentation and software for the Really Old School Computer (M68K)
As requested, just jotting down two thoughts on potential improvements: - At the moment EXPSEL is only broken out via J3, where adding it to J6 would make it possible...
In looking to re-use the SPI routines in the firmware for a non-SD device I've had issues with what _appear_ to be the output lines (possible the input lines too?)...
As detailed in https://github.com/rosco-m68k/rosco_m68k/pull/306#issue-1117449775 , it is currently not possible to hard reset the system other than with the on-board button, as `/HALT` is not broken out to a pin...
This PR moves the repeated code out of each software's `Makefile` into a unified `software.mk` that is included by all of them. The contents of `software.mk` is mostly the same...
Currently the BOM lists the run and reset LEDs as LEDn, which is confusing as these do not appear on the silkscreen. BOM should be updated for consistency with boards.
RX/TX markings on the board current reflect what should be plugged in there, rather than the pin function. This is confusing people, so swap it back.
In the interface reference docs, we state that the print traps leave A1 pointing to the null terminator. This no longer appears to be the case, we save and restore...
Currently, the GPIO software library is fixed to use the MFP both for Arduino-like GPIO and for SPI. This library should be fixed to be more flexible and/or call into...
When we cleaned up the multiple out-of-sync memory maps, we went perhaps a little too far - there is now no canonical map for the classic v2 😅 . We...
