- Yes, but you don't want to; it would be "bad". If you mix nasty PAGE mode
- RAM in with your nice SC ram, you won't be able to use the nice BURST
- mode, and gain memory access speed.

- A test program, like SCRAMmer will tell you without having to open up your

- 70ns 1x4 SC ZIP ram (the good stuff) can be had for $130/4 megs in
- c.s.a.marketplace, fairly often. There are 2 ZIPs per meg with this style chip
-
- Since you are asking these questions, I'll just go ahead, and post the whole
- schpiel.
-
- You HAVE to add 4 megs of ZIP ram at a time to your A3000; that's just the
- way things are.
-
- They are installed NOT IN A ROW, but one chip per bank, one for each of the
- eight banks, starting at the bottom of each bank, looking from the front
- of the Amiga.
-
- If you look at the socket numbers printed on the motherboard, you will see
- exactly what that paragraph means.
-
- Geez .. I think it's time I looked at Warren Block's A4000 Hardware Guide
- and created the A3000 Hardware Guide; everyone seems to be asking about
- SCSI, RAM, chip revisions ...
