  1. Hello guys! I need your help Atari 800, ATARI 800XL/600XL owners! If you guys own a caliber I urgently need to know which size in millimeters (or even better in keycaps unit 1U) the following keys: ATARI 800: - CONTROL key (to my measurements using pictures found on internet) 1.5U - LSHIFT key 1.75U as well as the RSHIFT - FUNCTION KEYS (Select, Start...) 1.5U - CLR SET TAB key 1.5U - RETURN key 1.5U ATARI 800XL - CONTROL key 2.0U - LSHIFT key 2.25U - RSHIFT key 2.0U - CAPS LOWR key 1.25U - RETURN key 1.75U - ESC key 1.25U - FUNCTION KEYS are spaced as 1U keysize. The only correct keyboard I can check is the Atari 130XE style... In attachment the PDF layouts of those keycaps (used by MaxKeyboard) and the keysize in keycap units. Please help me, Gianluca atari-800-xl-style-maxkeyboard.pdf atari-xe-style-maxkeyboard.pdf
  2. Ok, I will move it. Thanks, and sorry for noise.
  3. Hello guys! I know this question is OFF-TOPIC but as I see you guys own a caliber and some of you are owning Atari 800 and XL series, I urgently need to know which size in mm (or even better in keycaps unit) the following keys: ATARI 800: - CONTROL key (to my measurements using pictures found on internet) 1.5U - LSHIFT key 1.75U as well as the RSHIFT - FUNCTION KEYS (Select, Start...) 1.5U - CLR SET TAB key 1.5U - RETURN key 1.5U ATARI 800XL - CONTROL key 2.0U - LSHIFT key 2.25U - RSHIFT key 2.0U - CAPS LOWR key 1.25U - RETURN key 1.75U - ESC key 1.25U - FUNCTION KEYS are spaced as 1U keysize.

  4. Now everything is on GitHub for easy access and modification https://github.com/gianlucarenzi/A130KB_MX
  5. no. Its solution is a USB converter from a original ST keyboard. My goal is to have a 3d case as XE style with PCB and newer keycaps (no yellowing, no retr0bright): 1- with the USB for PC 2- without USB for drop-in replacement for Atari XE broken or yellowed keyboard 3- with USB with 4 more keys 4- with more 4 keys and usable with the original ATARI XE Computer but with a custom cover with 4 extra keys
  6. Next few days I will show you my 3d/schematics of the adapter board, or you can show me yours. What about the cut-hole of the keyboard Atari 800XL? How far from RETURN key are the function keys? Do you know somebody who can give me some measurements for Atari 1200XL or Atari 800 computers? 32 years ago, I bought an American NTSC 48K Atari 800 from Best Electronics (if I remember correctly) with two reconditioned Atari 1050 Disk Drives and a CX85 numeric keypad. I made an Electronic school project with its 4 joystick port (I wrote a special P: handler for Centronics Interface using two ports of the PIA (7 bit ASCII + a BUSY input line)) and it worked 😜 One Disk Drive went with a broken belt after few years... I remember I was used to have a 230Vac - 110Vac converter to use it, and the vertical blank was 60 Hz instead of 50 Hz ( I remember Alternate Reality Music and Game ran faster). The worst thing is: I DO NOT OWN THIS ATARI 800 ANYMORE. I DO NOT REMEMBER WHAT THE F**K HAPPENED TO IT. I thought I left it in the attic, but I cannot find it anymore. Maybe I lend it to someone who forgot to gave me back in the days... 😞 Can somebody gives me the cut-out keyboard measurements? Even the function keys cut-hole plastic and sizes... I need to deserve to Atari computers something good, because they gave me the opportunity to go to Tech High School and then to the University for Computer Science and Maths.
  7. As keyboard drop-in replacement the cut-out for the keyboard spacebar needs 9U. So depending on factory the 9U can be replaced by 6U and 2 1.5u keys or 7U and 2 1u keys. The meaning of this keys can be selected by firmware. Can be space, or inverse, or what the user needs. I hope I was clear.
  8. Ok, I forgot about the 1200XL. So the board can be used into it too. Really? With crimp flat ribbon cable (like HDD, FDD)??? 😕 I do not see any metalwork needs. All can be done with 3D plastic print. The project has to be easly adapted for every need because it's open source. Here is my PCB so far (some hours)
  9. Great job indeed! What're the upper left keys? It seems you are using the correct footprint of the keycaps/switches (HELP/RESET/OPTION/SELECT/START function keys apart) If you build 2 different PCBs: extra upper left keys and main keyboard (I suppose they are not standard footprint. I do not own any 800XL/600XL/800 at the moment) detachable, this can be easy to add a footprint for Arduino Style PCB the next time. What's the connector inside the Atari 800 XL PCB for keyboard? Is it a single line edge connector type like Atari XE? If so, I've just designed an adapter from EDGE CONNECTOR to 26pin flat ribbon cable (very thin PCB Thickness 0.8) so this can be used as well. Is there a way to reuse the lateral function keys? With a sort of cherry MX adapter under the hood? may I have the physical dimensions of the cutout on the XL plastic case? In the next few days I will show you the XE board design. Does anybody gives me the cutout dimensions for keyboard in 800? Even the lateral function keys cutout and possibly a picture of the connector on the motherboard. Regards, Gianluca
  10. I've asked WASD the custom keyboard layout. They told me, for some keys there is no problem, for other they are customizable only for VERY BIG Quantity (MOQ 2000 pcs/lot) because of the cost of the mould (the keycap will be Double-shot type expecially the dark brown ones (Atari 800 and XL Styles)) so I have only ONE OPTION: - The keycaps must be for XE Line (White/Cream with Dark Grey/Black Legends), and NO WAY TO HAVE BIG SPACEBAR (9U) from them. So, I have a couple of companies interested in this project, but they need MOQ (100/200 pcs). BUT MY GOAL IS: 1- Have a DROP-IN replacement for XE Line of computer with custom keycaps and legends 2- Build a PC USB keyboard using the same keycaps + some more keys usable with emulators (tell me which keys and how many) because I am start designing an USB XE Style keyboard case. 3- If some hacker need only custom keycaps for his/her project all keycaps are ready. At the moment this dream need 100 sets (at least) of keycaps for XE Line. I am building the PCB for (1) & (2) with mechanical switches and maybe at the end of october I will have some pieces. If this project will reach the MOQ for keycaps I will try to start the first production run for XE style stuff. When done, if there will be enough request for 800/XL style I can ask for how much for the new keycaps. They do not to be DYE-SUBLIMATED legends, but due to the color they need DoubleShot or Laser engraved (I will see...). But the production run will be MUCH MORE EXPENSIVE (anyway I am lucky enough to live close to https://matt3o.com so I can arrange a meeting with him within December, so I can tell you something more about XL/800 keycaps, so do not hold your breath)... (A) ATARI XE KEYBOARD REPLACEMENT (130 EUR circa): 1 - The Keyboard PCB + Cherry MX switches + electronics needed to use it into XE line will be around 70 EUR. 2 - The Keycaps for this will be around 50/60 EUR Mark (B) ATARI XE KEYBOARD USB (135 EUR + the 3D Print of the case [maybe someone knows how much it will cost?? 30 EUR???]) 1- as (1) above + 4/5 euros for an Arduino UNO type of board for USB HID conversion 2- as (2) above 3- the 3D Printed XE Keyboard Case for this project (Q: Someone with Blender/Cura for 3D Design or knowledge for designing this piece of art?? I will be glad to pay him with a complete Keyboard!!) and her/his name should be printed inside the case (like Amiga 1000 engineers!) (C) ATARI XE KEYCAPS ONLY (50/60 EUR) 1- as (2) above So now, you have a price-range information to think about. My email is: [email protected] Please feel free to contact me _ONLY_ if you are interested in (A), (B) or (C). After reaching the 100 preorders I will e-mail you back the way to pay for this project. So I know it's not very cheap, but if you are looking at the mechanical keyboard world we are in a mid-range price... But best of all IT IS UNIQUE. Regards, Gianluca
  11. What is TK-II/AKI? Anyway I know about WASD, I had a 104 keys ANSI with Amiga keys from them. USD $170. It's a very good mechanical keyboard. This is why I am planning to build custom keycaps and keycaps printing of the legends using a Cherry MX swtich and a custom PCB board for: 1- Replacing the original ATARI XE keyboard with PCB + KEYCAPS + FUNCTION KEYS 2- Building with the same KEYCAPS + PCB + USB MCU + OTHER KEYS (like config, speedup, loader... What else? I am open to suggestions... 3/4 keys are welcomed) 3- Having the KEYCAPS only to replace some already existing PC KEYBOARD CAPS. The main issue here is the size of some keys (Left Shift, Right Shift, Caps, Return and __SPACE__ ) are not standard for keyboards nowadays. No mention about the legends... Doing all stuff with WASD keyboard is very expensive and somehow not practical as they do not have spacebar 6U, 7U or 9U (as the original one) but only 6.25U. So you will need to have some weird in size keys lateral to fill in the gap to have a 9U spacebar. Like 1.5U + 6.25U + 1.25U... 😕 No mention about their price for each printing... My goal will be to achieve all keycaps for small quantity (like 50 or 100 sets) under the 50 EUR mark. (55/60 USD)... Who want to join the ride? I hope I was clear.
  12. Regarding this project I am trying to contact a guy named FelixMuerte who did an excellent 3D object for Atari 130XE (ref. https://it.3dexport.com/3dmodel-atari-130-xe-139144.htm ) So far I do not receive any good/bad news from him... 😞 Are you guys know anybody who is capable to design an Atari XE USB Keyboard using the same style and size of the Atari XE? It should be used in an Open Source project so it must be Blender compatible. If anyone were able to use 3D programs to create an Atari XE-style keyboard to be printed on 3D printers, I'd be really happy. And maybe make a 50% discount of the final keyboard price for him / her. Regards, Gianluca
  13. Before all of you are asking why there are not function keys for Atari XL and Atari XE, is the way they are built. I asked for a custom shaped key caps for XE and I am awaiting the quotation price, but for XL it is a different story. For both system (XL and XE) the easiest way is to adapt the existing keys with a custom 3d printed adapter, but for those of you who want to have brand new function keys the easiest way is to 3D-print-them. And paint them with the correspondant plastic-spray-painting to looks like the originals... I am open to every solution here...
  14. The custom case for MiSTer, Eclaire or whatever FPGA system is, can be accomplished AFTER we reach the first goal: having those damned keycaps! The PCB for keyboard will remain the same, as the USB to the eclaire input are connected inside the case, but the holes in the back need to be adapted for Eclaire or other FPGA Solution. If I were able to use CAD software for 3D, I would do it... 😞 In attachment both layouts: XE style (first production run) It can be accomplished (as stated above) for as low as 100/200 kits. XL/800 style (second production run, but it needs more than 2000 kits to start the production, because of the costs of the custom moulds) 😞 Anyway I would share with you all my steps so far. if in atariage there was someone willing to help me in this project that if realized it will become opensource, I would be really happy.
