An Acorn A3010 comes equiped with only 1MB RAM.
Some Games and Demos require more...
It is very easy to add another 1MB of RAM and i show you how to upgrade you A3010.
|
|
When you open the Acorn A3010 you will find two empty sockets at the lower-right on the mainboard. |
|
Under this sockets there are a few jumpers.
(LK20, LK21, LK22 ...)
The only jumper you will need to move is jumper LK22.
|
|
So change the position of the jumper LK22 to match this picture (move jumper to its upper position). |
|
Now you will need 2 RAMs of the following type:
HM514260AZ8
You can search for them in google, try Ebay or simply contact me ;-) (currently I have 2 sets of RAMs left).
|
|
Insert the two RAMs into the sockets Pin 1 facing to the front (Pin 1 is where the little cut corner is on the chip)
And you are ready to go!
|
|
Now your Acorn A3010 has 2MB RAM and is ready to play all this great games and demos... |
|
While my Acorn A3010 was open, i decided to remove the onboard CMOS battery.
I had to press "R" every time at bootup... So the battery was empty...
|
|
... and started to corrode the A3010 motherboard! |
|
I cut of the 3 legs of the battery with a wirecutter. |
|
And i cleaned the corroded parts with vinegar and then with clear water.
Now i have to press "R" ever time at bootup, but my Acorn A3010 won´t got eaten by batteryacid.
Maybe i will replace the battery with a new one in the future.
Greetings TOM:-)
