Perhaps I'm weird, but I'd populate the clock too, perhaps with a coin cell. The clock isn't wretched, it's the nicd barrel cell..
And while you're at it, a piggy back 2MB chip mod. :-)

The 7/10 is for the desoldering process, too much heat will damage the tracks feeding the ram chips, No need for the piggybacking when you can use the 1mb expansion board. One issue also is the height of the chips in the sockets, the new RAM chips in the sockets will make them a little too high and they will interfere with the keyboard laying on top so you have 2 choices, no sockets, or grind down the lower end of the chips to allow for clearance.
For the clock circuit there are quite a few components that would need to be added, i thought about it and figured the less modification in this case, the better
