Christian Vogelgsang, who a couple of years ago collected together the git repository of Tobias Gubener’s Minimig_tc64 project and ported the OSD menu code to GCC – thus sparking my interesting and subsequent foray into the world of FPGA development – has been hard at work once again!\u00a0 This time he’s succeeded in adding support for the Chameleon’s clockport to the Minimig core, which means that in theory a good proportion of clockport peripherals should now be usable!<\/p>\n
So far it’s only been tested with a Silver Surfer card – it will be most interesting to see which cards work without any further changes, and which prove to be troublesome.<\/p>\n
Links to source, binary and details of a small hardware hack required can be found on Chris’s blog – but before downloading and trying them take note that<\/p>\n
THIS MUST NOT BE USED WHILE THE CARTRIDGE IS PLUGGED INTO A C64.<\/strong><\/p>\n The IO mux code has been stripped right down to bare bones to give usable clockport performance, and the synchronization with C64 bus cycles is no longer present, so a connected C64 will definitely crash, and may even be damaged.<\/p>\n With that warning in mind, do check out his work here: http:\/\/lallafa.de\/blog\/2013\/09\/a-clockport-for-chameleon64s-minimig\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Christian Vogelgsang, who a couple of years ago collected together the git repository of Tobias Gubener’s Minimig_tc64 project and ported the OSD menu code to GCC – thus sparking my interesting and subsequent foray into the world of FPGA development … Continue reading
