HOW TO INSTALL 1MB CHIP INTO AN AMIGA 500 ON THE MOTHERCARD!
|
|
|
|
Note. This hack works just on Rev. 6A Amigas (or higher!)
|
|
|
|
You will need the following:
|
|
|
|
4 memory chips (44267 or pincompatible)
|
|
A LOW WATTAGE solder iron
|
|
|
|
PLEASE READ ALL TEXT CAREFULLY BEFORE YOU DOES ANYTHING!
|
|
|
|
Now open you Amiga (it's a hell to open those fucking nonstandard screws!)
|
|
(When you open Ya Amiga ya worrenty will go to hell, but if ya are a real
|
|
hardware hacker you don't mind!!) then try to find where the memory chips
|
|
are located! (under the keyboard on the left side where the memory expansion
|
|
should be located!) there will you find 4 EMPTY places for 4 chips! just
|
|
solder the new chips there! (with the SAME direction as the other chips
|
|
already have otherwise bad things CAN happen!)
|
|
Now locate jumper JP7A and cut the connections from ALL three bases!
|
|
then find jumper JP2 and cut the connections and solder a connection
|
|
between the middle one and that one on the top! so the jumpers should
|
|
be connected like this:
|
|
|
|
JP7A:
|
|
O
|
|
|
|
O
|
|
|
|
O
|
|
|
|
(no connection at all!)
|
|
|
|
|
|
JP2:
|
|
|
|
O
|
|
|
|
|
O
|
|
|
|
O
|
|
|
|
(The Top one and the middle one soldered together!)
|
|
|
|
|
|
|
|
and that should be it! (test the command AVAIL to check how much CHIP/FAST
|
|
mem you have! you should now have 104000 or something like that in CHIP
|
|
mem! (if you have downloaded ths from a BBS that was packed with LHARC by
|
|
me then AVAIL will be in this file too!)
|
|
|
|
|
|
|
|
NOTE: YOU CAN'T HAVE A MEMORY EXPANSION (LIKE THE A501) IN THE INTERNAL
|
|
PORT IF YOU INSTALL THIS MEMORY!!!!!!!!! IT GOT TO BE A EXTERNAL MEMORY
|
|
EXPANSION!!!!!!!!!
|
|
|
|
I WILL NOT TAKE ANY RESPONSIBILITY IF ANYTHING GOES WRONG FOR YOU!
|
|

|
|
|
|
If you have something to ask me feel free to call those BBSes and leave a
|
|
message to me: (Send the messy to John Hertell)
|
|
|
|
The Golden Arrow +46 26 275710 (-2400 BAUD) (I'm a CO-SYSOP there!)
|
|
Checkpoint Charlie +46 31 463582 (HST+)
|
|
Power Station +46 522 29360 (HST+)
|
|
|
|
Or in VIDEOTEX in Sweden send a message to: 52000161-1
|
|
|
|
or call my voice line on +46 522 75764
|
|
or a letter to: John Hertell, Box 5074, 451 05 Uddevalla, Sweden
|
|
|
|
Have fun with your 1MB CHIP AMIGA! (on the motherboard)
|
|
|
|
AGAIN i must say that this hack ONLY works if you have a REV. 6 AMIGA!
|
|
(they have a SUPER FAT AGNUS already!) The Superfat Agnus is called:
|
|
8372A! (it's that strange chip who looks like a box!)
