The Amiga 1000 had to get the Kickstart ROM from floppy into RAM in 1985. I think that counts.

The Amiga 1000 had to get the Kickstart ROM from floppy into RAM in 1985.
I think that counts.
- monocasa 3y agoI could see an argument either way. Particularly since the data on the floppy isn't directly addressable, so it's not really shadowing another region.
- cout 3y agoI don't think that does count as shadowing, unless the floppy is mapped into memory and then the RAM is later mapped at the same address.
- ecpottinger 3y agoThen you have to include the C64 where the ROM could be copied into RAM and then modified to allow extra functions.
- snvzz 3y agoOnce loaded into RAM, the WORM latch is closed and the RAM becomes non-writable, and accessible at a different memory address[0], which is the same address other Amiga have a physical ROM mapped at. 0. https://retrocomputing.stackexchange.com/questions/1140/how-did-the-amiga-1000-wcs-write-controlled-store-for-kickstart-work https://retrocomputing.stackexchange.com/questions/1140/how-...
