QUOTE=arfink;2681315] I'm thinking that looks less like a repair job and more like a bank switching chip. If you look closely, the chip is tied to pins on the V2, V1, and two jumpers, and has all discrete or passive components. It is marked Playmore on said chip, so it *should* be OK. Those boards must be amazingly expensive if they can't redesign them to put the bankswitching onboard.
I think it's for bankswitching because I have seen this kind of stunt pulled before, but mostly for much older supercomputer or mainframe hardware so that they could address more RAM or ROM than the board was supposed to be able to handle. [/QUOTE]
Gotcha. Care to give me the 20-second lesson on banking switches, what they do, and why they'd use one in a SSV cart? And PS, the Bank Switching board actually has SNK/Playmore written on it, which seems to me a surefire sign that it's legit.
That's definitely a legit cart.
Thanks! I thought so, but the chips are marked less than what I'm used to and the bank switching chip is not something I'm familar with in the least.
That said, the chips are marked effectively the same (if less) than older legit MVS chips, the bank switch board is stamped SNKP, and everything else about the cart seems kosher from the label to the sotter joints.
