Memory upgrade help

I am looking to upgrade the main memory and flash memory on a Cisco 4000 M+ router that I am using in a test lab. I have used Cisco's web site to find out the limits for this router model and opened it up to see what chips are in it currently. It has 16MB main memory and 4MB of flash. What is the best/safest memory to use for upgrades on an old router like this. On the main memory, the max is 32MB. Can I use any 32MB 72-pin SIMM to fill the slot?

As for the flash, there is one open slot that will allow me to add another 4MB. Is the flash specific to Cisco? Do I need to find a memory chip that is specific for the 4000? Any ideas on were to get it for a reasonable price? I looked on ebay, but couldn't find anything for this model router.

Thanks,

Jeff

Re: Memory upgrade help

I have a couple of the 4000's and found new memory readily available on ebay.

Thanks, I will keep looking there. I did end up finding some this afternoon but I need a 4MB and couldn't find smaller than 8MB so I will keep an eye out.
