It could be that is simply a single ROM chip that is used, replacing the 8k byte BASIC ROM. If so, the start address will likely be 0x0000 so that the CPU executes it at power on.

I ask in all ignorance and wanting to learn, how does either the 4k 2732 or 2k 2716 inside the unit replace the 8k zeddy ROM?
Does it boot up from either one of them then hand back to the zeddy ROM to handle its housekeeping duties etc?
If so how does the zeddy ROM hand back control to the module?
Sorry, in a rush to finish my post as the train approached the station I was getting off at, I appear to have made a bit of a mess of it :oops:

Thankfully Siggi has cleared a way through the fog... :D

No worries Mark it happens, I find the idea of the module booting up with a bit of its own ROM then using the rest of the zeddies own ROM a brilliant idea.

Notice Word Sinc II.3 does not use regular 32 letter columns with uppercase letters. It uses 40 letter columns with upper AND lowercase letters. See here: http://www.zx81.de/andre/zx91/_frame_e.htm
