What, if anything, do the extra ROM sockets on the A1000 do?

Computolio · 14 September 2004, 02:35

If you look at the Amiga 1000's motherboard, just below the boot ROMs are two sets of empty holes where another pair of ROM sockets would go. I have a hunch- what would happen if someone split a 256K Kickstart into four 27C512(64KB) EPROMs and filled the four sockets with them? Has anyone ever tried this?

What Jay Miner said about jumpers works equally well when applied to sockets:

"Don't touch unknown [sockets], even if they are labeled free sex and beer"

The two empty sockets are available in case somebody wants to add Kickstart ROMs to an A1000.

You do not have to remove the BootROMs though, they will recognise if a Kickstart ROM is present or not.

But that leaves only 128K, or is there something I'm missing? I thought that bigger ROM chips won't fit, since there aren't enough pins in the sockets.

Also: what happens to the Kickstart RAM? Does it turn into Fast RAM?
