hey folks,

i'm playing around with an old wall street (250mhz). i had read that one could install 256 mb ram into both the top and bottom slots. to give a total of 512.

i played with the top slot first (easier to get at) and installed a 256 (pc 100 stick). unfortunately, in the system profiler (9.1) it only appears as 128 mb. does anyone know what's up with this? is there some fancy way to get the mac to recongnize the wealth of memory that it now has? the ram came from tiger direct (ultra brand).


thanks, onon.

I think only single sided ram will work in a wallstreet ... I may be wrong but it might be different with the top vs. bottom slot ( I remember seeing at one point that you had to get different ram for top and bottom) so maybe you can try it in the bottom slot...

MacDoc

It needs older ram with mutiple chips - the newer individual chips are too large for hte model to recognise fully.
So double sided with lots of chips are what you are looking for. Good luck

Likely a sodimm with 8 chips per side will work.

thanks david,

i guess in this situation it makes more sense to get the ram from one-world-computing or some such intelligent mac distributer over tiger direct. i'm sure i'll find a more effective use for this 256 stick i've currently got .. . . well anyway, thanks as always.

Yeah, those ancient models required 16-chip DIMM's.

hey david,

would you happen to have any of this ancient memory kicking aorund?

yoyo

I was able to get a 256 meg low profile chip for the bottom slot on a wallstreet
from ebay a few months ago.

MacDoc and Lars are right, it needs low density modules. There isn't really a difference between the top and bottom sockets, it was more about the physical size - when low profile modules were more expensive, vendors offered a kit of a tall (2") module and a low profile (1.25") module as a way to lower price. Now that virtually all modules are low profile, this distinction is no longer significant.

Tiggerdirect woudn't be the most expert place on Mac stuff..

There are some good, Mac-knowledgeable vendors in Canada. If you're in a major centre, then independent Apple dealers would be an option.

Otherwise, PM me for some suggestions.

Thanks

Onion have to look.
You might find a bargoon on the high profile top slot memory as there are few other uses for it.
Are you going to run X??

no, i'm planning on running in OS 9 as i'm just going to use the wall street as a print server and terminal to power my serial devices. (laser printer, scsi scanner, wide format ink jet .. . etc .. . . )

let me know if you find something. zev@tao.ca
