Love these early 1200XL units!

The 1200XL serial list is holding at 630 entries.  It seems there has been a slow down in 1200XL sales/listings.

 

Cue The A-Team theme:

"If you know of a 1200XL, if someone you know does, and if you can look at it, maybe you can submit the serial..."

A viewer donated an Atari 1200XL to me as seen on my recent SMMC 0066 video. It has the Best keyboard membrane (but still has a few keys not working properly, viewer reported keyboard was completely non functional before the membrane swap.)

If it has the new best keyboard membrane installed and there are key problems I expect it just needs opening up to see the gold contact on the keyboard's PBC are making proper contact with the Best mylar. I can't imagine the Best keyboard membrane it's self wil have failed.

Perhaps the person who installed the new membrane failed to realise that he needs to scrape the hardened old adhesive off the gold contacts where the membrane contacts meet the PCB. That replacement is supplied with a shim which should not even be necessary if the keyboard repair is done properly.

It's not that, it's just 3 keys (tab, 2 and 5) and they work just not well. It depends on how I push the keycap/slider down.... like 2 works if I push on the edge of the keycap, but not in the middle of left side. etc. A bad membrane contact will surely result in entire rows or bunches of keys not working.

Very true. I guess dismantling the keyboard and cleaning the contacts under the problem keys will be the way to go, then.
