  1. Found the thread where I applied the firmware upgrade, where I was made aware of RD5 etc. Guess at the time I was no longer thinking of what this meant for the EclaireXL. Also this explains why it works on the 600XL automatically.
  2. So where does it get RD4 and RD5 from on the XL?
  3. I'm looking at making a new EclaireXL firmware and when testing I noticed that the IDE Plus 2.0 E no longer works on it to work on it, or on my old EclaireXL firmware where it used to work! I think I might have updated its firmware in the meantime... Anyway this pin 39 RD5 thing explains it. In the EclaireXL we'd decided to use some of the spare PBI pins too and CCTL is on pin 39 - I'd completely forgotten! So to make IDE Plus 2.0 work I had to cut that trace and run a wire from RD5 on the cartridge port to pin 39 on PBI. @Larry, thought this finding might interest you since it probably explains why it used to work for me but not for you!
  4. Apparently that is the JTAG. Found this very important post which explains that I need RD5 on the PBI connection, but not just RD5, RD5 via a diode!: Edit: Actually he says later in the thread this was fixed in the CPLD, so only RD5 to PBI pin 39 is needed. No diode.
  5. Ahh... Is is that little header next to the compact flash? Funny this works on my 600XL, I guess it just drives out stronger than the basic rom does!
  6. Thanks. I guess it must pull refresh low then like turbo freezer and syscheck, to disable the mmu.
  7. Do you see KR1 and KR2 go low when you press a key?
  8. I've forgotten how something works on PBI! Please can someone remind me how RD4/RD5 are handled on upgrades like the IDEPlus2, which has a cartridge slot on PBI. i.e. how does it disable internal basic since EXTENB is high and the MMU has basic selected?
  9. The pi keeps losing its usb drive mount. Tried a powered hub and a usb drive firmware update - no luck:( Just rebooted in any case.
  10. Thanks. Hopped over there to post some info.
  11. Yes it’s that demo and loading the 2nd part that fails. I get a red screen. PAL 600xl
  12. Ok so it’s not even booting at all? Not a keyboard issue? Can you boot games from disk?
  13. So it boots to the basic prompt but you cannot type? Does break or shift work? If you hold down option(start, select and option are handled by gtia) you can use the keyboard test to check. Just like to confirm you have no wires connected to the pokeymax? The pokeymax counts on k0-k5 and gets key pressed on kr1 and kr2. Could check those on the scope. FJC recently had one (first case I’ve heard) where KR2 was not soldered properly to a little io expander chip in the bottom right corner.
  14. I tried the Latest 5.4 release and that failed too. So I checked it with a 1050 and pokeymax - that combination works. Might be that the app has a timing bug rather than a respeqt issue though.
