Title: Which RAM chip for my Accelerator?
Post by: sir_bacharach on June 12, 2013, 06:39:06 PM

Hi,
 
I have a Blizzard 120 IV Phase 5 Accelerator and I'm looking for the correct type of RAM for it on ebay.
 
Here are a few links.
 
Not sure which one is correct or if they both are.
 
http://www.ebay.co.uk/itm/128MB-EDO-MEMORY-NON-PARITY-60NS-SIMM-72-PIN-5V-32X32-/350478815002?pt=US_Memory_RAM_&hash=item519a2a4f1a
 
The above link confuses me because it says 5V and 32x32, whatever that means.
 
http://www.ebay.co.uk/itm/128MB-MEMORY-32X32-72PIN-NON-PARITY-FPM-60NS-5V-RAM-SIMM-/130593572400?pt=US_Memory_RAM_&hash=item1e67fbc630
 
The above link says Fast Page mode and 16 chip, which I assume means it's got 8 chips on each side.
 
Can anyone shed any light on this?
 
I recently bought some RAM that was specified Accelerator RAM but it's physically too big to fit on my board, the processor gets in the way.
 
I can tie wrap it in but the RAM protrudes and the trap door won't go on which means I'd have to leave it off and put extra feet on the AMIGA for clearance and I think that looks a bit scruffy. :(
 
Rob.

Aha, the bottom link can be ruled out as there is no notch cut out of the chip.
 
Any ideas if the top one is suitable then?
 
Thanks.
 
Rob.

The first link looks correct type, the EDO 72pin.

The second link is a 30pin SIMM, the pic does not match the description.

Make sure your SIMM is one sided, not double sided or it may not fit.

Just asked the guy, he knew straight away that they don't have SIMSS for Amiga accelerators. :(
 
Bugger.

Just a quick glance but this should work, and it's from a guy who's very active in supporting the Amiga community.  Check it out:

Settled on this one on ebay, not a bad price, don't know what import tax I'll have to pay though.
 
Fingers crossed it's not too high.
 
Asked them to make sure it's low profile and gave them the measurements of the smaller stick I have that fits.
 
I do hope I've not wasted more money. lol
 
Thanks for your replies.
