NOTE 1: for the M4GA, 4D, and 4P
require soldering wires from an oversized EPROM to various points on your
TRS-80 motherboard. You need to have
soldering ability and be able to follow instructions. The modification is reversible if you run
into troubles - remove the oversized EPROM and clip off the added wires and you
can return your computer to normal.
NOTE 2: the NF6X adapter board works
well if you want to install both the Auto-Boot Eprom
into a Model 4 Gate Array or 4D and flick between them with a switch. For more information check the NF6X website. Again you need to be able to solder but the
end result is a neat little modification.
Thanks Mark.
