Either the system will be held together with patches, retargetting commands and glue logic (the flash ROM is 2Mb in size, four times larger than an A1200's ROM)


They did say the flash could also softkick a rom image, so it must have at least 512kb free..anyway the A1200 can use a 2mb rom, it`s just that no-one made another rom after CBM went tits up.

As for patches and glue logic, is it a bad thing? Without them we wouldn`t even have 060 cards.

The only thing I don`t like about this, is it`s not a plain trapdoor type accelerator, but (in Elbox`s words) a modular system with separate busboard and cpu card.

It can? There's only 1MB reserved for ROM in the 24bit address map though.

Well, according to the A1200 memory map...
A80000 to B7FFFF 1 MB   System ROM
E00000 to E7FFFF 512 KB   System ROM (second 1/2 if 1MB rom)
F80000 to FFFFFF 512 KB   System ROM (first 1/2 if 1MB rom)

Hey it just occured.
Someone is missing from this thread.


That`s cos this thread is already about Elbox, and not about a competing product from E3B or Individual Computers...
