This page showcases my small collection of obsolete and antique electronic devices (mostly computers).
Zenith DataSystems (ZDS)
Computer trivia: ZDS introduced the "clam shell" design for laptops!
ZDS SupersPort model ZWL-184-97
Specs (as reported by Norton System Information):
ZDS SupersPort 286 model ZWL-200-02
Specs (as reported by Norton System Information):
ZDS SupersPort model ZWL-184-02
Specs (as reported by Norton System Information):
ZDS SupersPort 286 model ZWL-200-04
NON-FUNCTIONAL! The HDD was broken, and has since been a parts computer. Needs new floppy drive, hard drive, and power supply / video board (on the Zenith laptops, the video circuitry was built-in to the power supply). Has an Intel 80286 processor ? MHz.
ZDS SupersPort SX model ZWL-300-04
Also NON-FUNCTIONAL! Needs new floppy drive and power supply. Has an Intel 80386 processor and was last known to run Windows 3.1.
ZDS SupersPort 286e model ZWL-200-41
Specs (as reported by Norton System Information):
These are two of the batteries for the ZDS laptops:
They both hold a charge, and can power the laptops for at least 1 hour before they go dead. Their model numbers are: ZA-180-57 (rear of picture) and ZA-180-85 (foreground of picture).
TI-99/4A
This is the Texas Instruments TI-99/4A computer. It hooked up to your TV, and runs "TI-BASIC" without any extra modules installed. I installed the fan before I realized it's value as a "pre-historic" computer. When I got it, it was not working. Within a few seconds of being turned on, the video went crazy. I stumbled on a fix for this by soldering a short piece of wire to the video chip inside, weird! I have all the documentation and the box that it came in (my next-door neighbors were giving it away for free at a yard-sale).
TI-59 / PC-100A
My dad brought this calculator home from work. He said nobody had touched it in a while, and figured it wasn't needed anymore. This is the TI-59 programmable calcualtor with PC-100A security base / printer. This calculator has been described as the world's best programmable calculator. I have the following program modules for it: Master Library, Math/Utilities, Leisure, Business Decisions, Surveying, and Applied Statistics. From browsing through the math/utilities and master libraries, it looks like it can do just about everything my TI-83+ graphing calcualtor can do except for graph.
