Replacement DRAM for 800XL

Recommended Posts

I am needing to replace a couple of damaged DRAM chips in a 800XL.

 

I found these on Ebay for a good price.  $12 USD (shipping included) for a set of 20. From what I can find, these should work.

 

Does anybody have an opinion on these chips or any advise on what chips should work?

that is a good price for 20

they are 150ns, anything ove 100ns is supposed to be fine

Glad to hear.  Because I had already ordered them before I made the original post. I was getting worried that I had purchased a batch of useless chips due to the low price. Compared to the others being offered on eBay these seemed to be a steal.

Supposedly the maximum latency A8 can use is 250 ns.

But generally the bulk of the 5V DRams that suit the XL/XE will be under 200 anyway.

The vital thing is to not buy MT branded chips - though I can't say I've ever seen them being sold.
