I haven't opened up a PCjr in ages, and don't remember what they had inside. But that's the right vintage, so it might be a source for these chips.
And if you do decide to upgrade to 512K, post back. I have complete directions on how to do it. It involves a non-negligible amount of surgery, and also changes your 128K into a non-stock machine, though, so I don't recommend it.
It will be staying a 128K. I like to keep them as they were made and I have a real 512K too. :)
