i just recently found that my old DOS utility disks had finally got to old to read. fortunately i have the disk contents archived on an external HDD. but the disks were in some rather handy plastic cases, and being a packrat, did not like the idea of just throwing them away. fortunately, they are exactly the right size to put mini-cd's in. so my first box will be filled with slackware mini cd's burned from alien bob's mini-cd images from here:

maybe one mini-cd can be loaded with freedos and all the utility programs i have archived. i do still run across some older machines from time to time that need some hardware testing done on them.....
