Just got me an A500+ :-) with no bits :-(
 

Hell, it's stained a dirty yellow and the expansion board is held in with blue tack.

So,

I need to bodge together a power supply - any know the pin configuration?? I've got an ATX supply in the shed that might do the trick.

And a mouse.

And a lead to connect it to a TV or monitor.

Thanks for some URLs!!

What am I going to do with it when I get it going? :confused

Look in the 'hard/hack' directory on www.aminet.net for lots of DIY adaptors. Very good sounding mouse adaptor - ps2m.lha (requires a PIC chip)

You'll find lots of cable pinouts on www.hardwarebook.net
(pretty sure they have Amiga power connectors)

Connecting to a TV... If your TV has RCA connectors for A/V in, then you can just connect directly via those cables from the Amiga (I believe?)

Otherwise, get a co-ax aerial cable, cut off the end that doesn't connect to your TV, & replace the plug with a RCA. Plug that into the Amiga, then tune the TV to the right channel (something in UHF).

Considering the fact it's an A500+, did it come with an A520 Modulator? (would be written on it) else you need to buy one or buy a RGB to scart cable else you wont be able to see anything.
