Too bad I got here late for the POST...
I have a 32 mb, FPM @ 60ns Simm with flush mount chips (total thickness of the SIMM is 2.5mm) that is used at the moment on my Blizz1230... it came out of a PC, which recognized it as 16mb and at the time I had an 8mb Simm stuck in my 1230, so I replaced it with it, and to my surprise it was a 32mb simm, ran a MEM test on it and it functioned without flaw...
I would have sent you this baby for the reimbursement of the Shipping Charges... but glad you got it to work anyhow...
