Do you want to make the C16 more similar to the Plus 4?
With this memory expansion you can load all kinds of games and programs dedicated to the Plus 4.
Have you tried to load Treasure island but halfway through the load the Commodore 16 memory runs out? Yes, because the C16 has only 16Kb of RAM and for some games it is not enough, with this small card you can have 16K or 64K on our C16.
I got this expansion card on this site: https://idoregesz.hu/product/commodore-c16-internal-ram-upgrade-to-64k/
In the kit you will find:
N.1 board with components already welded
2 RAM chip 41464
N.2 16 pin sockets
N.2 Sockets 18 pin
N.1 Connector with 2 pins at 90º
N.1 Cable with 2-pin connector
1 Step
First you need to remove the screws of the computer to open it, disconnect the keyboard and remove the motherboard.
It will then be necessary to have a soldering iron and perhaps a gun desoldering iron or alternatively a tin sucking pump and desoldering braid.
If you follow the guide on the site it will tell you to cut the pins of the components, yes it is easier to remove them and you do not need a lot of equipment, but if you do so throw away some good components.
2 Step
Remove the components indicated by the instructions on the board, i.e. U5, U6, U7, U8 and once the pins have been cleaned, the supplied sockets can be soldered in their place.
3 Step
It is necessary to find 2 pitches to take the power supply of the board, in the picture the first two pads are visible (where the tin is removed) where the 2-pin connector can be soldered.
4 Step
All that remains is to insert the 2 RAMs on U5 and U6, connect the power cable to the board and insert it on the sockets, test and close everything.
The photo shows the entire card with the memory upgrade installed.
Now you can choose whether to have 16Kb as it was previously or whether to have 64Kb like the Plus 4 and be able to load all the programs!
