The very first modpack I played... well I don't remember much from it. However, I do remember a few thing very well; it had GregTech and it was extremely hard (just imagine, back then, there were not a single wiki in anything but english, and I wasn't speaking it at all. So, first time, hard mods, and the only docs were hard to understand... yeah it was pretty hardcore. But it was fun after all....); but the point here, is that I also remember very clearly one thing; the pack was customized a bit, and it was called "Feed The Beast Beta Pack B". And, I'm pretty sure the pack was listed on the launcher... but I can't confirm that part. Well, fine, I checked the wikis.... and nothing. I tried Google of course... Deceiving. There's one result on a wiki contributor page in german, it's mentioned once on this forum, and that's about it.
So my big question is wether there was really a "Beta Pack B" and if so, how it was different from the A (because, I know for sure that if we (me and the people I played with) chose one and not the other, there were definitely a reason), or is that name just how we renamed it back then, and there never was any "FTB Beta Pack B" and the few result founds are just typos?
