hi everyone. just after some opinions/advice on my new sid build. i currently have a v1 midibox sid which i built a few years ago. it has the minimal control surface. 1 core, 1 sid (6581), 1 din and a (now broken) LCD. all the pcbs are the original revisions from mike's. i've aquired an extra 3 sid chips, so i now have 4 (1x6581, 1x8580, and 2x6582). i would like to upgrade to v2 and build a full control surface whilst leaving myself the option of adding extra sids later (when i can afford them). so my question is this: what can i reuse? i gather i'll need 2 cores and 4 sids, and that v2 uses a new pic on the core. but can i reuse my current boards. or will i be saving myself a whole load of hassle by just ordering a full set of new boards? thanks. k
