Battery powered A1200

[rustednail]

Hope this subject is still warm!

I believe some lap-top batteries might have all the voltages needed to run an amiga.  Seems like lap-top batteries have several pins out and I would guess its different voltages for verious parts of the laptop, but it has been quite some time since I have looked at any lap-top battery specs.

Could a old lap top display be used on an amiga?  I have an old lap top here, a 486 machine thats has a cracked case and wasnt worth much on e-bay.  I might pop it open and see what the vid connector to the display looks like

Did Pawls do that already?

PAWs wasn't the most impressive creation... I saw the A600 version and the screen was horrible. It looked like a satellite phone more than a laptop and the pixellation was horrendous.

I think you need -12v for the RCA phono jacks which are also linked somehow with the serial port (MIDI maybe?).

It may also be the case that an '060 board might be less hungry for battery than an '030 since the former runs at 3v and the latter at 5v or thereabouts.

I never really delved too deeply into electronics but surely if you put a load of batteries in series/parallel (which is which!?) then you could multiply the battery life as much you liked?

I'd be tempted to experiment with a solar/windmill powered Amiga. You can get super efficient Panasonic solar panels for around £3k GBP now and such a setup could be used to generate and control power to your entire house and manage the sale of excess generation back to the National Grid. A moneymaking idea if ever there was one!

Yup, you need both +/- 12v for the audio op-amp and also the line drivers for the serial port (to get to the std. RS232 levels)
