Spectravideo 80 column card & Super Expander repair

In this video I start out to take a look at the Spectravideo 80 column card - the SVI-806. But things didn't quite go to plan...

Cheers - another very interesting video. I'll be printing one of those component leg benders tomorrow! Yeah, unfortunately Spectravideo cut a lot of corners regarding connectors / assembly in my books.

Those diods were not of the best quality it seems. Out of the four super expanders I have encountered, three of them had to get exactly the same treatment that you performed in this video.

I had the C.U.C. 80 column card with auto switch mode. U fortunately all my stuff was stored at my parent's house and got thrown away when they moved😔

[@tassiebob]

Shame your stuff got ditched :-( In my case I voluntarily got rid of a lot of stuff that I now wish I still had :-(
