32 pin ram simms

[swift240]

Hi guys,
Ok in the local council are renovating the area, and I have been told to clear the loft out for possible new roof.
So in to loft I went and amongst a load of comupter gear I found this:-

Its a RAM expansion module for an Atari 520ST.
On it has 1992 MP Atari ST210A
it has got 2 32 pin ram sims on bord, and each has 8 chips
41256.
WIth room for another 2 32 pin ram simms

I have another 2 ram simms some where, not sure where I put them now.

Are these any good to any Amiga user here?

This module worked but I stripped the Atari down as the case was cracked but the mombo was in perfect condition.
I have still got all the kews but nothing else.
The Atari was a freebee any way so I didnt ever use it, I just switched it on.

Mike.

32 pin simms?
Are you sure they are not 30 pin or 72 pin cause those are the standard ones.
Also two 30 pin simms are not much use, most simm carrying memory cards use banks of four (even A500 chip ram cards use four 256kb simms)

Blimey, yes they are 30 NOT 32.

 If the SIMMs are 1Mb each (or more), you can hack them to make your own A601 memory expansion!

 For details on how achieve it, look at my hack on Aminet: "tabajara" (what a exotic name, you could say...).

30 pin simms are very useful in the amiga world, a lot of a500 sidecar expansions take them.

Huh?

30 pin SIMMs are used by many A500 expansion boxes and A2000 cards, so they aren't worthless. Usually you need at least 4 however.

Sounds like a Marpet 2/4Mbyte STfm RAM upgrade. Worth £50-60 even without SIMM's.



If it is something different, post a picture.

Actually, folks, 32-pin SIMMs DO exist. I held four of them in my own little hands once. We ordered four modules for a PC upgrade, and that's what we got from our vendor. As I was snapping them in, I noticed that the SIMMs had an extra pad on either side of the socket that didn't have a corresponding lead.

Things that make you go "Hmmm..."

So, we call the vendor back, and the reply was "Oops! That's where they went... You shouldn't have those - we'll send a pickup for them, and get the regular ones out to you."

We never did learn what they were for (I'm guessing some kind of server or printer, as the 30-pin can have a maximum of 16Mx9, a 32-pin could give you 256Mx9).

If those chips EACH have 41256 printed, then they're 256Kx8, but double-check to see if there aren't any 44256s on 'em. They may have set them up differently to get a 1Mx8 layout.
