-
- yep...place the next 8 ZIPs to the second bank (first are your DIPs).
-
- > - Secondly, is it not true that all the RAM chips must be of the same

- If they`re mixed, no SC-Ram should be placed to forst position
- in bank 0 ->> your 1.st DIL. Otherwise you`ll have to get one none
- StaticColumn DIP.
-
- SC end with 02, 03, 12 (514402-80)
- the slow ones with 00...

- Have a look on there type...there is a failture in the ramcontroller
- which disables the use of SC with the old "Ramsey-04".

-
- These days you`ll get 16MB of standart Jedec72-SIMMS for 4MB ZIPs....
- A friend of mine will announce an adapter for the A3000 which is can be
- used for 2 8MB SIMM modules ...please be patient.
