RE: [N8VEM-S100:4164] Multiple Rom Monitors and a conflict

[Thomas Owen <thomasbr...@gmail.com>]

Hello Everyone,
I should have been a little more clear with my statements...

I install the rom, either one, in my Ram17 board by simply removing ram chips.  So, either one will work installed by itself in the system.
I can access all functions of both roms just fine.

It is when they are both installed in the system together, one at e000 (myiderom) and the other at F000 (masterz80) that neither will work.
I start the system, reset, and try to run from either start address and the system just hangs.

I think John is on to the problem as i believe they both are trying to use space occupied by the other rom, thinking it is ram.
What I need to do is set the top of ram below the rom at E000 (I think!) within each rom.

Summary:
Masterz80:
Ram 0 - EFFF Rom at F000.  This works fine.

Myiderom:
Ram 0 - DFFF, rom at E000. This works fine.

Masterzz80 and myiderom together in system:
Ram 0 - DFFF, Myiderom at E000 to EFFF, Masterz80 at F000 to,FFFF.  System simply hangs trying to launch either rom.

Thanks again,
Thomas
