Something I've noticed recently is that most of the TF resource sites don't have a Diaclone list anywhere. I'm curious if anyone knows of a decent checklist where I can figure out what different versions exist of the Diaclone/Microman TFs.
That's because Diaclone isn't Transformers. While the two franchises are closely related for obvious reasons, it's still a separate entity. There were other lines besides Diaclone repurposed for Transformers that aren't listed in resources as well. If we did Diaclone, we'd probably have to do those, too, and that would be a lot of work for something not part of the Transformers brand.
If you are really interested, a quick google search yielded a page of Diaclone catalog scans here. Diaclone Catalog Scans « Transformers Roll Out
Thanks for the heads up on that site, found a couple more through Google. Shame that Diaclone doesn't get more coverage, but as long as ehobby keeps cranking them out, maybe there'll be hope yet.
