A500+ cpu upgrade....advice needed.

Mark sealey · 19 September 2019, 10:01

Ok right I have a A500+waiting for a cpu upgrade....for use with a Z-500 Zorro slot and a old retina display card....but I don't know what accelerator to go for.

ACA 500+
TF530
Witcher 500I

I don't need a 020-as the retina card don't use CGX or P96 ?

Any advice would be greatly appreciated.

Thanks all

Mark

I only have experience with the TF530 - I can't recommend because I don't know if it will work with your card. It may or may not work, I just don't know.

I have a SupraRam 8MB side expansion that won't work when using the TF530. But it appears to be the SupraRam's fault. From what I can tell, the SupraRAM doesn't autoconfig properly into the RAM space. It assumes that it is the only expansion RAM on the A500, and hard codes where it should reside in memory.

Aside from that my only issue with the TF530 is that it only has 2 MB of RAM. That might be OK for you, but I wanted to run WHDLoad, which requires at least 4 MB. That's why I'm onto the TF534. The 534 runs great for me, but there have been reports of it being unstable for others.
