Guys, if any of you would like to be put on the orders list, please send an email to jurek (at) retronics (dot) eu, or via PM. I need your declaration of purchase (what item, quantity) and shipping address (plus e-mail). If I collect enough orders, I may then start production.

Hi Duddie!

 

Read through this...

Is the 1200XL possible?  If so, is there more than one type?  How can we identify what we have?

 

Most importantly, would a new membrane cure the normal 1200XL keyboard issues (anybody, especially Bob1200XL). I know that I've fixed several with the "Make-a-trace" marker, but that is not a really good long-term repair.

Yes Jurgen. AFAIK, there are 5 different XL keyboards, four of them have membranes. But it is the same membrane.


You mean only one type, type 4, has a membrane: http://atariage.com/...-1#entry1274425

All 1200 & 1400xx that I have ever seen use the same Mitsumi keyboard.  Best Electronics has mylars for them.  That is almost always the problem.

 

It would not hurt to make more, because Best may run out eventually.

 

I would love one for my original 800 Mitsumi (which, is sadly different from the above mentioned ones).

Is anybody able to send (can be faulty) membranes for 800 (not XL) and 1200XL? Maybe someone has also 400 keyboard?

Just curious-

What usually causes the mylar to fail (especially 1200XL's)?  Is it mechanical fracturing, trace damaged?  Or?

The near-universal failure mode for 1200XL keyboard Mylars is at the contact points for the ribbon cable to the rest of the system. By and large, the key contacts and traces are fine. The fix is annoying and time consuming but easy. Well documented for years on retrobits.net

I would be very interested to know if Original 800 ones will be available.

 

Others with this same question should speak up NOW.

 

:)

 

 

Bit late, but not too late to say I'd like one too, even if the mylar are fixable, it can never hurt to have a brand new one that will last another 30 years (by that time, I won't be able to type anymore anyway.... :D

So please do a run of Atari 800 Mitsumi mylar please :)
