Explansion Card Memory

keitha1200 · 22 June 2012, 19:00

Well I've been getting in some practising on the soldering, before i tackle leaking 600 caps

2x A500 memory expansion card, both had leaking batteries (something that people seem to forget about/mention).

I'm wondering if the memory on the knacked card is useful (picture; 2 and 3)?

The braid stuff is pretty good

Comments/advice welcome

The smaller board must get a lemon juice treatment and tracking repair, from the shown pictures.

clock batery´s was amigas biggest mistake they should be designed with separate modules because of amigas low acces to interior,many motherboards and expansion ram cards was lost during age because of the battery´s

you can do repair of tracks with 90 per cent conductive silver paint on ebay and since is not a visible thing ,what matters is the repairing it self .

Yeah, looks like the one with the OKI RAM will have a broken RTC at least.

Thanks for the posts

Does someone have a ebay link for the proper sliver and PCB spray? I keep getting stuff about eyeliner! and sliver just doesn't match my eye's

Think trying to repair the memory expansion, might be a good/fun project
