A500 Modulator fault or want to trade for working PAL A520
« on: December 12, 2010, 10:47:08 PM »
I've just picked up an A500 1.3 and the original owner stated it was in working order. Aside from the fact I only paid £11 for it the modulator only outputs in black and white (tested modulator with a working A600). I have tried tuning the A520 using all 3 turny things inside it but no luck.

Does anybody know what the fault is?

If it's not fixable I'm willing to swap for parts I have (A500 mice, PSUs, floppy disk drives, blank disks, Commodore 1084 monitor lead - these things are rare ;) ) for a working PAL A520.

Could be an NTSC model, that'd give you a B&W picture on a PAL machine.

I could loan you a working modulator for you to try?

Where abouts are you in the UK?

Bolton. I'm 85% certain it's only the modulator at fault.

If you're willing to pay postage both ways - I can loan you a known working modulator to test your theory with.

For anyone else with the same fault - the modulator was duff. I picked another up from ebid for £5 incl. postage, rehoused the internals into the original 520 (better enclosure).

Now how much could I get for a working, non yellowed, boxed 1MB PAL A500 1.3 and extra boxed games (UK postage only) ? :) No Workbench disks tho :(

BTW did the 1.3 A500 ever come in the Cartoon Classics pack - I know the Plus was swapped when C=  started running out of A500 stock but was the change over in this set?
