Wonderful Hungarian Civil Radio has changed its IP, so it is no more working on the SymbOS WebRadio app. Tomorrow I will release a new fixed version.

This is the new IP.

Ah!, ok.... again I have read faster than needed....

You must update wifi loading a file from your phone(from Windows it fails).

I don't remember well the procedure, wait.

Proceed to internally update the CPLD. Connect the SF3 to the PC with the DFU cable, but with the DFU switch on the lower position. Press reset. The OLED screen will show you "Z80 update needed" or a similar text. press the middle button and wait wilr the OLED shows "Updating". On "OK" you can re-connect the SF3 to the EP.

Also, there is a copy of the LOG file that is stored on the SD every time the SF3 is updated. You can read the DFU version in the file.

Search on the SF3 SD directory:  SD:/SYSTEM/LOGBOOK.TXT


The easier method, sorry for remembering it the last.

Actually the settings of the serial port are: 256000 baud, data bits 8, stop bit 1.

Also the MIDI data modes can be monitored, and then the settings are: 31250 baud, data bits 8, stop bit 1.


The program I use on the PC side is PuTTy.

OK.... I misunderstood all the conversation... it happens for reading too fast.

The SF3 has a diagnosis port at the rear, a 6 pin header, that is used for developing. It reacts on real time with the SF3.

I use Putty to connect to it with a USB to serial module.



The LOG file is also written to this port, so you can know what firmware version the SF3 has.

The pin-out is exactly the same.

Tutus' SF3 crashes when connected to the EP, but not when connected to the PC by the USB DFU cable. Or at least is what I know.

Yes, but that online WIFI method has been dropped since the internal Jtag is being used.

An internal CPLD update needs the SF3 to be completely unplugged from the Enterprise and the adapters, because some short-circuits can happen on the programmable chip, breaking the SF3.

Hans is a one-man-orchestra... he will update the manual on time...

Soon a new DFU will arrive, with CPLD update.

Developing for for the SF3 connected to other computer, a Sega SC3000, he has found a way to speed-up some internal file uploading/downloading processes, so all computers will benefit.

I would like to create something similar to that today, with SD card instead of the floppy ...

The software of the SD cartridge is so well written(by Zozo, of course) that it doesn't need to be on the cartridge address range, 03-07, an external cartridge bay can be connected on the expansion connector on other selectable range.

Then, you can have the SD cartridge as if it were the EXDOS interface, at the right side, leaving the cartridge bay for other tasks.

This external cartridge bay was planned by Zozo when we found that the MIDI interface Rom only was able to work on the 07 segment. Since then Geco has fixed the Rom in several ways.

Ok... I am an expert on nothing... only an enthusiast apprentice that repeats like a parrot what Zozo, Istvan, LGB, Geco and a long list of other geniuses say here, on recent times including you.

I have managed to modify three computers, and this means exactly that. The research of the information that has lead to the knowledge is the work of Zozo, but not only from him, because overclocking on the EP has some tradition on Hungary, with even commercial products, or at least is what I have understood, when Zozo mentions one type of clock switch better than the one he uses.  

Also is truth that the EP was projected with a 6Mhz Z80 clock in mind, some proofs can be seen on its code, ask Bruce about it.

And now that you mention the Enterprise sequel.... it was already projected, effectively with a 6Mhz clock as standard. It had shape and was real, now we know. You can see it on Werner's thread.

Have you read this thread about overclocking the EP?

Thanks to this tutorial from Zozo there are a lot of EPs running up to 10Mhz flawlessly.

I have successfully modified three machines.
