[M100] Source for LCD polarizing film?

I'm finally getting around to looking at replacing the curling polarizing film on my 8201 and wondering if anyone has a good source for something that's a close match? There appears to be a lot of options out there... with and without adhesive. Thoughts? -- -- Brad Grier

Re: [M100] T200 and the Year

I don't have direct experience with the 200, but if the date is handled the same way it is on the 100/102/8201a, then it's a ROM thing. An expansion ROM (like the REX#) or a patched 200 replacement rom should be able to fix it. Here's an example of how you can patch a NEC PC-8201a ROM.
