Originally, this $2000 wonder came with W95. I still have the 29 install floppies*. At 1.8 Lbs and about the size of a VHS* cassette, it was unique in it's time. Built-in expansion is through a single pcmcia slot. There was one open memory slot, it only came with 16 MB of RAM.
A friend was sufficiently impressed with the machine to buy it's bigger brother, a CT70. This one has a P-120 and was upgraded to 32 MB of memory. A couple years back he gave that one to me. I put DSL on it and used it for over a year until I bought a new laptop. It remains usable, with full apt-get and available Debian Woody repos. Opera even has up to date packages for Woody, I just put 9.64 on it.
After the arrival of the faster machine, the old CT50 didn't get much use. I wiped W95 and put Basiclinux on it, booting from DOS/loadlin. BL boots and runs fast and is compatible with Slack 4 packages. It has the driver for my network card so it remains usable. Still, it's more of a museum piece and occasional test bed.
* Remember those? I'm showing my age here. And no, I did not pay full new price for it.
