- Hi all,
-
- >>What it sounds like he was saying is that all VESA machines
- >>have memory wait states.
-
- According to what I know, this is not correct.
- To ensuer 0 wait state for VESA local bus peripheral devices,
- the memory which has an access time less than 60ns/40ns is
- necessary for 33MHz/50MHz*1 VESA bus clock systems with very
- tight timing margins.
- (*1 50MHz peripheral slots are not reccommended from the VESA)
-
- But, some graphic cards which have a good memory system design
- are working with 0 wait states.
-
- I don't have any idea about the Zeos machines, sorry.
