Hi there,
I've used the original NEC Mulyisync (Model: APC H4311)
and Multisync II (Model: JC-1402HMR) on my Amigas with no probs. Both will display all modes, including AGA ones.
As an aside I've also used the same monitors with the following old stuff:
Oric-1
Oric Atmos
Spectrum +2
Spectrum +3
SAM Coupe
Commodore 128
TRS-80 (a few different ones)
I'm actually wanting to sell my NEC MS and MS II monitors if anyone in Australia is interested!
Cheers,
Mike.
