You should be able to do that with the V1.1 board yes... V1 no.PaulJ wrote: 06 Mar 2020 18:04 @exxos , can I use the IDE board but insert it with no processor and use the on board H4 processor? I suspect not but thought I'd ask.
Good, my goal here is to have a machine that can run the uip tool and have the eprom emulator working. I need the IDE boards $e00000/$0000 decode for the eprom emulator and the H4-1 works with the netusbee. So I will run the IDE board without eprom but using its decode signal to drive the eprom emulator that I will plug into the IDE processor socket on an adaptor. Everything should then work. By the way the only thing that successfully runs the eprom emulator is the IDE eprom decode. :) :) :)
Sounds like a plan :thumbup:PaulJ wrote: 06 Mar 2020 18:16 By the way the only thing that successfully runs the eprom emulator is the IDE eprom decode. :) :) :)
Didn't work, must process some of the cpu lines or something one the IDE board. Just a white screen. I'll wait for the H4 $e00000/$0000 decode board. :coffee:
Id be surprised if you did get it to work as nobody has the V1.1 yet other than Icky and we not even tested the firmware yet...PaulJ wrote: 06 Mar 2020 22:26 Didn't work, must process some of the cpu lines or something one the IDE board.

According to the Fitter Report (V5_1504A.fit) file for your design, the Fitter failed to fit this design mainly because it wasn’t able to route A8, A20 and IDE_IORDY to some of the Logic Array Blocks (LAB) as shown below.
For the ATF1504, there are forty 9:1 multiplexers for each LAB to connect all the input and feedback (total of 132) signals to the macrocells as shown below. Furthermore, each input signal is connected to 2 muxes while each feedback signal is connected to 3 muxes. So for your design, it’s likely that the muxes for the A8, A20 and IDE_IORDY input pins need to be used for other input or feedback signals, and this is why it failed to fit. To fit your design into the ATF1504, you can try removing the pin assignments for A8, A20 and IDE_IORDY from your CUPL design file and then see if it will fit or not without enabling any of the Optimization options.
