- I have a 3000 with 2 meg chip and 2 meg fast, which is made up of 4x256K Zips
- (not sure whether they are static column or not) That makes 16 chips for the
- 2 meg fast, am I right??
-
- Anyway in order to transfer my chips over to the 4x1MB static column Zips, and
- increase my fast memory from 2 meg to, say, 4meg, I understand that this
- will require 8 chips per meg, which equates to 32 chips. At $14-15 per chip
- we have $110-120 (US) per meg. Down here that equates to over $200 per meg
- which will cost me at least $400 just to get back where I started
-
- What I want to know is: Are these assumptions correct? Can anyone both in NZ
- and overseas confirm this??
-
- Obviously 8 rather than 4 of the 4x256K Zips are required to make 1 meg. Again
- I assume this is because of the 32 bit requirements.
- And likewise, 8 of the 1Meg chips are needed for 1 meg of memory with
- those chips.
-
- Sorry I'm not a techie! AdvaTHANKSnce... Matt
