PCB revision on 503A

External Since: Apr 17, 2004 Posts: 4

Hello,

I'm to buy used 503a, but I've no information about PCB revision. As far as
I know there were four: 1.0 -1.3. Can anyone tell me what's the difference
between all of them? Do all 503a's support 1.8V-core? And finally: Does 1MB
L2 cache has to be in two chips, or the absence of one says that it's 512kb
version?

You want E-O037 1.2A if you want to run K6-3+ at 2.0v.
I think you are right about the 1M being 2 chips, and 1 chip is 512k
