  1. Under footnote 6 - the XEGS keyboard connector has 15 pins, not 9. Good table!
  2. Finally made up my own case for one of the through hole units - I wanted it to look somewhere between the styling of the 800 and the XLs. Designed a faceplate in Tinkercad to fit the OKW case, and used an external antenna.
  3. Would you mind posting the UF2 for this (and if you try subsequent) versions? I had a lot of trouble with his XEP80 code too. Thank you!
  4. @bfollowell Mine worked fine on a purple clone as described in the instructions. Maybe you have a USB-C cable that is just for charging and doesn’t have the data pins? And would still like to see you come up to the Indy Vintage Computer Club - there is a meeting this weekend!

    Would love to see it open sourced - I like to build my own hardware. Version 1 was easy if you could find the parts... Thanks!
  6. Hey! You're welcome to come down to the Indy Vintage Computer Club meeting which occurs monthly and you can get help there. https://www.facebook.com/groups/IndyVCC Check in with me if you think you can go and I can let you know if I am going and will bring some stuff to help you troubleshoot.

  7. All of the versions of AtariWriter80 I could find would drive the XEP80Pico - but it seems to initialize the screen margins to 32 and 71 - so I couldn't find a usable one.
  8. I went back looking at where my problem was with the first build - and it seems that your uf2 file is the working one and it differs in a hex editor from the one posted on the Polish forum (which I cannot get to work). Did you build it yourself or where did you find it?
  9. I did make a PCB to carry the components shown in the earlier schematic. Seemed easier than the circuit origami to fit it in a plug. Message me if you are interested in bare boards like item #1
  10. The resistors and the level shifter circuit are under the Pico on the Topside. My plan was to have the Pico socketed so it could go into other projects if needed. I will have some of my reworked boards if anyone is interested. I will have pin headers on them to solve the not plated through problem and a bodge wire to fix a pin misassignment.
  11. So - it was my first time using JLCPCB's assembly service and I thought I was making it easier using their EasyEDA software... Made one mistake myself and then found out the Pi Pico in their library had a footprint - WITHOUT plated through holes. But with a little board rework, I would call it success! I need to clean up the mistakes before I consider posting the board files somewhere.
  12. Got it working! A thing of beauty. Think it was your drivers, although I noted the schematic picture had pin 38 of the pico tied to ground and the creator wrote a text file using pin 3 - so I wired that up too. There are many many ground pins on the Pico - doubt it is the issue. Great picture and simple build.
  13. Yeah, I got those demos to work off the pico previously - so pretty sure the hdmi side of the wiring works and the pico is alive. Thanks for the files - looking forward to troubleshooting with them!
