There are 3 ways to get 64K VDC video RAM: buy a C128D, replace the two 4416
DRAMs in the video can (u23, u25) with two 4464's (18-pin, 120ns), or buy a
"solderless" VDC RAM upograde kit from SSI (206)695-1393 (about US$50).

Assuming option #1 is out of the question, consider the kit from SSI if you
are not a technician.  Desoldering in the confines of the video can is not
easy.  The solderless tower simply requires you to remove the socketed 8563
chip, install the tower, and stick the 8563 into the tower.

I personally have not seen or used the SSI thing, nor am I connected in any
way with SSI.  I have just heard good things about it (save for the weak
instructions, but the task is rather simple).

Needless to say, Commodore does not recommend these hacks, and such hacks
are done at your own risk.
