If these are the same ones that have been up on ebay recently, then they will not necessarily be suitable for all Blizzard accelerators - many of the SIMMS that I have seen advertised were double-sided and some Blizzards require single-sided, or at least a 'thin' double-sided, and quite small profile. Not a lot of room in an A1200, certainly not as much as in an Acorn RISC PC.
I'll take a look, just not quite yet.
