VT100 emulators

[u at isis.UUCP]

Due to a small windfall, I am now able to afford a small computer.
I want to be able to use the system to access the UNIX machines at
school. My budget limit is about $800-900, so I figure on looking at
the following systems: C64, C128, Apple IIx. My question is: what
VT100 emulations are available if any for these machines? If not a
VT100, what about other common terminals? Will they give true 80x24
lines? 


					Thanks,
