The listing, Compaq AERO 4/33 has ended.
How old can a laptop be? I think this one comes as close as you can get.
With it's 255MB hard drive and a whole 4K of RAM, this laptop will handle only the very basic letter writing and ultra basic games originally packed within DOS 3.1. This laptop has ONLY 1 PCMCIA type 2 slot. No Floppy drive, no CD drive, no USB.
There are a serial port, DVI, and Com port across the back. Comes with the AC power supply, and the battery quit charging quite some time ago.
With the right RAM upgrade, it could be made to run Windows 95 or Linux.
Winner pays shipping. Flat fee USPS is $11 but I'll ship by whatever carrier you prefer.
