I cna;'t help you, alas. IIRC, some RMLs used the TI 3-rail 2716s that 
most programmers can't handle. I assume you've checked for this...

I've just checcked my 'Information File'. The CPU board schematic says 
'2708 or TMS2716' for the EPROMs. In other words 3-rail (+5V, +12V, -5V). 
There is no EPROM on the 40 col VDU, the 40/80 col one shows a 2516/2732. 
That's a signle-rail type (TI were the odd-one-out here, their 2716 was a 
3-rail part, their 2516 was a signle-rail one like everyone else's 2716). 

I wonder if that's the problem you're having...

I am pretty sure that my 380Z has COS 3.4 (and I assume that's what the 
label is referring to
