MAPROM isn't supported and nobody knows how it works. It's all built into TOS now anyway. MAPROM isn't needed anymore, that was the point.

I don't use that as I don't want cached ROM anyway. If this is an option, then fair enough, but if it's hard wired into the firmware then I think it certainly would annoy some people. Me people!

Why not use fast-rom, your just making GEM painfully slow to use for no good reason.

90% of the time if I'm using the desktop the VDI and AES are soft-loaded replacements anyway. I don't want things going on behind the scenes that I don't know about or can't override as I'm usually looking for my own bugs anyway. Introducing more factors into the mix is actively unhelpful.

I'm really after any addons I install to be the lightest touch possible to do their job. If it's a 50MHz 030 with TT-RAM, great! I'll happily run some extra software to get the best out of it -- including declaring the RAM. I don't really want all the bells and whistles on by default as so little is compatible with all the bells and whistles that I like to choose the ones I want at boot time. The ones that *are* compatible with the bells and whistles will probably be run from the desktop after the drivers will have been loaded.

It's why my rev2 DSTB1 went the other way: everything is off until software turns it on. It does actually have a ROM-in-RAM mode (it can even load that ROM from disc), but you have to intentionally turn it on.

Running TOS from TT-RAM is no more “behind the scenes” than loading a replacement desktop into TT-RAM.

Yeah sure. If it's softloaded by the user into GEMDOS memory pool.

If it's built into the hardware with transparent remapping of the memory and no off switch, then I don't agree.
