WTB: Software for my old Mac LC575 / FS: Mac IIsi

[AlphaKilo470]

I just recently acquired at a garage sale for $5usd an old Macintosh LC 575 (really brings back memories, these are the same exact comptuers my elementary school bought when I was in second grade to replace the Apple IIe systems they had) with OS 8.0. However, since I'm mainly a PC user and have been so for as long as I can remember, I don't have much software for the old Mac. I was wondering if anyone here has anything since there seem to be a few Mac enthusiasts on this forum.

Things I'm looking for in specific would include:
MacOS 8.1 Upgrade CD (I'm using 8.0 and the lack of HFS+ is killing me)
Old versions PageMaker and Illustrator for 68k Mac
Any games that run on 68k (DOOM and Duke Nukem especially)
MS Word
MathBlaster (been too long since I last played this)

I'm also looking to buy a 33mhz 68040 chip to replace the 33mhz 68LC040 currently in the computer.

Also, I have a Mac IIsi without monitor (there is keyboard and mouse though) that I'm looking to sell. It has 16mb RAM, 80mb hard drive, OS7.1 and a few old games as well and WordPerfect. I'm open to most offers (for money or trade) just so long as they can cover shipping expense.
