A newer 40GB IDE drive will speed things up (originals were 4-8GB I think). I have a few Wallstreets and they are so easy to work on. The original 233 used a dual scan 800x600 screen that sucks. newer models used a 14 and 13" screen 1024x768. There are zip drive and LS120 drives that fit in the floppy drive/cdrom port. You can have 512MB RAM (2x256MB PC100). Early units can do 83FSB while later ones are stuck at 66 so you can do 292Mhz or 300mhz CPUs.
