There's more differences, listening to the pair they behave quite different. I'm guessing the response time of the opto-isolators is different, but perhaps more? I have vague recollection of this being described in detail here before, perhaps some groups searching would bear fruit. Additionally, the 300 series has a couple LFOs.

The 300 series Borg is a dual module, i.e. it is really like two
1200 series borgs in one box. It also has two LFOs on-board
(that produce Triangle, Sawtooth, and Square wave outputs).
