Plus Too works! Holy cow, it really works. Hot damn!
I didn’t want to tackle SD card loading yet, so the GCR-pre-encoded 800K disk image resides in ROM, just above the Macintosh ROM image. The floppy drive module uses the video module’s memory access time slot during hblank periods to load disk data, transparently to the CPU.
Plus Too ran for about five minutes while I took these photos, then it locked up. Not bad for the first boot.
Now, to celebrate with a cold beer!6 comments
