Hello everybody.
I have a WANG WLTC laptop computer (circa 1980's). I do not want to sell
it for cash, but I'd be willing to trade it for another unusual
portable/laptop.
Here's some specs on it:
-NEC V30 (8086) processor
-10MB Winchester Disk
-External Centronics-type SCSI port (HD is also SCSI)
-Built-in thermal printer, with roll/cut sheet capabilities
-512K RAM
-RS232-C Serial port
If you're interested in it, email me, and I can send you more info and/or a
picture of it.
There is, however, a problem with the internal (regulating/switching) power
supply. It runs the computer, but keeps blowing a capacitor. It also
needs an external P/S and battery. The battery is 10 sub-cells (with a
resistor - I have a schematic). A Tyco 20VDC racing transformer (the kind
for the little car/track sets) will run it.
I had an offer to trade it for an IBM PC-Radio, but I never got a reply.
If anyone has one of these, or any other odd or unusual laptops/portables,
and would be willing to trade, let me know.
ThAnX,

Hi Jason:
This is just a guess, but I think that the 'blown capacitor' problem is
directly related to the 'TYCO' power supply. It's output IS going to be
_very_ noisy, when compared to computer grade supplies. The peak voltage
is probably what's killing things. I would look for an 18v supply.
