Have to agree with Crom00 here.....
Best bet, look for the cheapest SIMMs you can find, and then buy a couple from different sellers... if you want to be safe....
I got lucky, ran across an EBay listing with 128MB SIMMs.... the seller was obviously not into computers.... when I asked her if it was single-, or double-sided, speed, etc. , she was quite confused.....
Anyway, the $15.00 SIMM fit my 1260, worked fine... so I immediately contacted the seller and bought a second one. :afro:
So, give it a shot, and if/when you find a suitable SIMM, be sure to ask the seller if he/she has another for sale.

Otherwise, maybe someone on here has a spare 64MB SIMM....
Note: I do not have a spare 64MB SIMM.... I have 2 spares :laughing:
