  1. @jamm, where are you located?
  2. I understand that it's an expert, but just from reading your process description it seems like a lot of work and it doesn't save alot of money. You will destroy original keyboard, which probably could be saved, you have to glue keycaps and 3D print a guide. It's possible to get anything on a blank keycap even at home. One way is presented in this video: Since you own 3D printer, you could attach small laser to it and print on your new blank keycaps. I think you can even get a white laser toner and print on black keycaps to match XL keyboard. You could create a jig to print on multiple keycaps at once and soon you will be producing multiple new Atari keyboards in no time.
  3. @ivop, recently I got some of those switches and they require a lot of force, I would not consider them for typing more than a few commands. They also are quite wobbly and the kay caps going to look crooked in the keyboard. You can see it here https://hackaday.io/project/169711/gallery#1ee3ddf1f69e4b3ab151874f84463d68 Like I said before, you can buy MX compatible switches very cheap https://a.aliexpress.com/_dSZUUfe same goes for key caps. The only problem would be how to get Atari specific characters and symbols on those keycaps.
  4. I'm working on the same thing, actually XE keyboard but it has identical layout to XL one. The keycaps has standard sizes. My plan is to use MX compatible switches from AliExpress, they are around $1 for 10, so whole keyboard would be around $7. Keycaps also from China and function keys would be 3D printed with MX mount or resin casted. I have done schematic for XE keyboard in KiCad, right now i need to make the PCB. I also want to use FFC connector on the keyboard PCB and smaller ribbon cable with adapter board on the computer side.
  5. Since everyone is carrying ebay in theirs pocket, it's very hard to get a good deal locally.
  6. Are you trying to make a mechanical keyboard for XL? You could ask @Duddie, he made new membranes for XE and XL computers, so he should have the measurements you want.
  7. Some places already sell Pokey chips for $65 and since PokeyMAX replaces original chip, you can sell it and get PokeyMAX for free or even make $5 On top of that, you get stereo and all the other PokeyMAX functions for free. I know that we can't make new Pokey chips, but every PokeyMAX installed make one more Pokey available. It may drive the prices of original chips down. Not to mention that PokeyMAX can save the life of another computer, 5200 or 7800 Ballblazer cart. Does PokeyMAX can be used in 1088XEL/XLD motherboards?
  8. For second Pokey, you can use $40 PokeyONE.
  9. Cleaning is one thing, but what about making rubber more elastic and softer?
  10. What about this one? https://www.ebay.com/itm/174217172012
  11. Yes, I did two with @Mr Robot excellent guide. @gs80065xe already have SDrive-MAX build and he doesn't have to trash his $80 device. He can fix it by swapping his UNO for new one for $3.50 and some easy software flashing.
  12. Likely only $3.50 https://a.aliexpress.com/_dT3vwKz The only downside is that you have to wait for it, but you could educate yourself in that time. https://atari8bit.net/everything-sdrive-max/
  13. Since many people buy premade SDrive-MAX anyway and you still need to make uno2sio pcb, I am thinking about combining display and microcontroller on one board. The cost for pcb will be only slightly more than for current uno2sio pcb.
  14. @tschak909, you could also try Facebook. Recently, I discovered Atari Chile group with over 2200 members that seems to be pretty active. https://www.facebook.com/groups/840633719349481/
  15. Another one is http://www.atari.org.pl/forum/index.php and most suitable subforum is http://www.atari.org.pl/forum/viewforum.php?id=24 "Fabryka - 8bit", which means factory. It's dedicated to new software and hardware projects. Most users can communicate in English, but don't be surprised to get response in Polish. You would have to translate it. Some one already mentioned your work over there http://www.atari.org.pl/forum/viewtopic.php?id=16351
