The C64 won't give you a real 80 column display; it's only capable of doing 320x200 pixels, so you're stuck with a maximum of 40x25 using 8x8 characters, though some terminal emulators give you 80x24 or 80x25 by creating very thin characters. Not something I'd recommend for long term use. The C128 has a built-in 80 column display that'll give you nominally 80x25 characters using an 8x8 cell. It hooks up to a standard IBM style RGBI (4 bit digital --> 16 colors) color monitor or a monochrome composite monitor. Some folks have managed to squeeze 760x600 or so pixels out of the C128 80 column display in interlace mode, but that's too flickery for normal telecom use. The C128 and C64 have the advantage of being able to use the dirt cheap Commodore 1670 1200 baud modem. This comes with a VT100 emulator for the C128 which isn't perfect, but is currently being fixed at Commodore. The disadvantage of either machine is that they don't work well beyond 1200 baud; the C128 might do 2400 OK with the right terminal emulator, but the C64 can just about handle 1200. I don't know much about the Apple II series these days, though you can get real close to an Amiga500 + Monitor + Modem for around $1000. It can use just about any monitor and any RS-232 modem. There are at least two freely-redistributable VT100 emulators which are good enough to run GNUmacs, uEmacs, VN, and CCalc without a hitch. I think the one called HandShake passes the complete VT100 test suite that was posted hereabouts a year or two ago. All Amigas can give you a fair 80-90 column display, which 25 lines non-interlaced or 50 lines interlaced (some folks don't mind this interlace flicker, some do). There are also more sophisticated and free telecom tools for the Amiga, like a VT200 emulator and some serial-line networking tools. -- Dave Haynie "The 32 Bit Guy" Commodore-Amiga "The Crew That Never Rests" {ihnp4|uunet|rutgers}!cbmvax!daveh PLINK: D-DAVE H BIX: hazy "I can't relax, 'cause I'm a Boinger!"
