Subject: have PowerMac 5400 to give away
Newsgroups: comp.sys.mac.vintage

I've got a PowerMac 5400/180 to give away. It works, although it no
longer has a battery to backup the clock. It's got System 7.5.3 on it,
not a lot else. Keyboard, mouse, and power cord included.

These beasts are heavy as they include the CRT monitor in the unit.

I'm located in Edmonton, AB, Canada, so if you are local, you're welcome
to come pick it up.

If you're interested in it for the price of shipping, contact me and I
can figure out how to pack it securely and how much shipping will be.

Quite a nice old Mac for anyone living handy to Edmonton.
Downside is the heavy built-in CRT.
Upside, the motherboard is easily swapped into an LC/Performa/Quadra 630 or Performa/PM 6xxx series Macintosh giving those machines an easy uprgade.
