Memory Question [Apollo 1260] Will These Work?

[phiwer]

Hi,

does anyone know if these memory modules would work in my 1260? I know the apollo is a bit weird regarding memory modules, if anyone has any experience with these, please let me know.

32MB 72 pin EDO SIMM RAM memory HP 1818 6431 AS IS (170761098472)

Hiyas Philip

unfortuantely I cannot give you a definitive answer in regards to that specific module, but my experience suggest to say away from HP branded products. instead I would suggest you look for 32MB 72pin SIMM's at 60ns or faster (thats lower i.e. 50ns) with 1K refresh - not all vendors will imediately know what refresh rate their products are - but a good search of the memory IC's onboard at

www.alldatasheet.com

will give you an idea

Printer memory is not compatible with many brands of accelerator cards. You require standard 32mb 72 pin FPM or EDO RAM: otherwise you will run into trouble.

What is the difference, on a technical basis, of ordinary memory modules versus printer? To me, it would seem odd for HP to develop completely new types of memory modules specifically for printers.

What makes you certain that these are printer memory modules btw?

The ram you see is 72 pin 32MB EDO.

I used to work for HP. I agree with the great Z. It was a PITA making sure we had the correct memory modules for different hardware. HP seem to have always had a policy of using proprietery memory.

Aha!

Interesting.

But I guess trying won't damage my card?

The ram you see is 72 pin 32MB EDO.

HP were and probably still are, real SOB's when comes to their hardware. Printers were designed around the RAM not the other way around, thus basically ensuring all those tech peeps had jobs for the future.

Dell used to be the same with their PC's - change a knackered CPU fan for a common every day one and some systems bellyached about it.

Hello Phiwer.

In this case I would suggest that you look up the SAMSUNG sticker and its part number.
It seems to me that SAMSUNG has a " normal" part number there and HP just puts its own Sticker on to ASSURE and CERTIFY compatibility with its own printer purpose.
I can't say for sure, the picture is not clear enough to make out the correct numbers.
Give it a try.

Regards.

Unless you can get the specs and verify that the modules will definitely work I wouldn't recommend it.

I admit trying an HP module in my A500 expansion years ago and the Ram chips soon got very hot, very quickly. I removed them before anything happened.

Some printer memory SIMM have a rounded chip in the middle: those modules are 3.3V, and they can destroy your accelerator.

Be warned.

The 1260 is operated at 3.3V if I'm not mistaken:

I haven't received the memory modules yet, so I can't do a definite search on google for these memory modules.

only cpu work at 3.3 volt

the ic 74543 and 74257 adapt data and address voltage to 5 volt for comunication with a1200 and fastram

the pinout of simm socket is ever 5 volt

Thanks for pointing that out!

just arrived 4 simm from usa, but are different model respect the photo on ebay and no good for apollo
