Replacement DRAM for 800XL

[Obadiah64]

 

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.

it is v.good value but at least youre covered by using ebay

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.
