So yeah, the ST206 was apparently one of the early models they worked on and it appears to not have made it out to the market. There's a mention of it here in this article: https://books.google.com/books?id=I...st206&hl=en#v=onepage&q=seagate st206&f=false
Also a few other mentions of it if you search books.google.com ... Here it is listed available for purchase, sortof: https://books.google.com/books?id=o...st206&hl=en#v=onepage&q=seagate st206&f=false
I found the same with the ST278 ... the Seagate ST11R tech document describe this model drive, but it does not appear to have ever made it out to market.

Anyway, I'd love to find an ST206 or ST278 ... I would like to imagine that a few examples do exist, if Seagate built them at all. Anyone ever come across these?
Was there really a 5MB version of the ST-212 (ST-206)? A quick google search reveals nothing and I’ve never seen it mentioned anywhere before. Didn’t know about the ST-278 either!
Glad to see someone else who collects these old drives too! They need to be saved just like the computers themselves do! I think having an old PC with a real MFM drive in it adds a lot of character.
