30 pin simm size
Noob question - I have a couple of 30 pin fastram simms for a GVP TBC+ and I need to determine their size in MB. Online guides say check the first 4 numbers of the ic's on the simm for 4256 4257 4258 as an indicator of 1MB size for example; these simms have different numbers. They are also different brands and 80ns which seems slow?
The simms suiting the TBC+ card are 1Mb or 4MB. TIA. |

No worries. The fastest I have seen is 70ns in this variety of chip array & I'd put it in the realm of 50n/s 72 Pin SIMM's which are equally as rare for that type of SIMM.
