alrght, that makes more sense. it's a second-wave 80gb model, then - software compatible. it was AFTER those models - the F, G, etc models - that they took out the card reader and the extra slots. if it was a MSG4 special edition, it'd have a different code on it.
you've got the same one i've got, i just forgot that mine had the card reader. except for a few instances (FFXII final battle's a good example), they're just as good as the hardware-emulation models, and the blu-ray player in them is the better version that doesn't jam or crap out as often. in my opinion, they're the best backwards-compatible PS3 you can get nowadays, notably since it's rare that you have issues with the hdd size in them.
