Thanks, that's what I thought.

@PaulJ does sound interesting. Do you still need rom decoding for tos2.06?

Yes, anything that runs in the $e00000 area needs the enhanced decode that you can get from Exxos's IDE boards, decoder board, the Lightning ST, or possibly PP's IDE board. Sure there are other sources including roll your own... Also the $fc0000 decode coming from the glue needs to be combines as Exxos does for his eprom on the H4.

I know for sure that PPs IDE board for the Megabus has the decode.

Received the H4 adaptor for the Emu27c400 today. Built one up and all appears to work fine. So @rubber_jonnie I'll attach the gerbers and you can build one for your system. The one I just built still need to have the flux removed but it's working as expected. I'll build one without 40 pin socket to decrease the eighth. Much easier than building an adaptor by hand. The single wire is the decode signal which in this case I'm getting from Exxos's IDE 1.1 board.

Ahh, that's awesome! Thanks very much.

Good luck with the board @rubber_jonnie , remember pin 1 of the adaptor is 180 degrees out with the Emu27C400. I suspect the Mega adaptor will be here later this week. I believe I may add PP's IDE adaptor to the board so essentially I'll have the IDE interface, $e00000 decode with all in a smaller board foot print than IDE 1.1 not to mention slots for 8 TOS images. We will see. @cmorley I have to order the program adaptor to upgrade the boards but plan on upgrading. I'm also thinking of adding a ST app to change the TOS image being used. We shall see.

Sounds fantastic, good job.

I don't understand this - do you mean update the firmware? If so you don't need any special hardware just the USB connection & a DFU utility for your platform of choice (I use the STM Cube Programmer which just works... it is Java based so PC & Mac I believe).

P.S. nice work on the adapter very tidy. Is that red flylead wirewrapped? I can't quite tell from the photo.

Yes, I thought you said in a prior post to upgrade the firmware you need a STM Cube Programmer. If you don't need it then I'll have to give it go. Yes, the red wire is wire wrapped which currently gets the decode signal from the IDE 1.1. The Mega adaptor should be here later this week and I expect it to work since I also build a prototype for it . Next step will be to add the decoding on board and if I really get crazy add in the IDE interface from PP.

Ahh... it is software not a piece of hardware.
