Btw, an interesting piece for SymbOS & ASM programming: https://github.com/z00m128/sjasmplus/pull/116

SJASMplus seems to have some on-going works to support SymbOS relocation table support. As far as I know, till now only winAPE's bult-in assembler supported the needed functionality.

Hi there,

We were speaking about writing a Symbiface3 USB driver to use this feature under SymbOS on the EP. I checked the MSX and the CPC M4 driver, and as I saw there is only 3 OS calls that have to be implemented by a driver to make a storage device work. Two sector based I/O calls using LBA, and a drive ready call. Then Gflorez said that there already is a SF3 driver for the CPC, and as we see, it could be easily - or with some port number modifications - used for the EP as well. But they said that the current EP version of SymbOS is using some other mechanism, I guess EXDOS calls for storage manipulation.

My question is: is there or can a version of EP SymbOS be made with the original sector based calls, so that we can make a try with porting the CPC SF3 driver for the EP? Please, release the hive mind knowledge about it!

Thx,
Agent K

Hi All,

Yesterday i was able to make a small movie to show Trebminds update on the G9k game mode for SymbOS.

Here you can see how it works:

Running it on the CPC

It is now fully compatible on the CPC, MSX and Enterprise. However i was not able to test it on real hardware as my Enterprise is still @Zozosoft and i hope i get it back someday (it is hard to reach him) If i get it back i can test it on the enterprise as well. As I believe it should work in the enterprise as well. Or maybe someone has the hardware to test it? It is to bad i can't as the enterprise is such a lovely machine!

Would be happy to test. Have an G9K connected to my EP.

Cool! Do you have SymbOS running with G9k already?

The chips are still there but indeed currently very expensive to buy.. and take the risk for that. That is to sad. Not sure if technobytes makes them?

Anyway, i can't help it.

Yes. I understand how you feel. I do not have a enterprise anymore and wait already for 2 years. I hope some day to have a working system again. A month ago I patched the radio app to work on the enterprise as well. In a way v9990 works on the enterprise as well, but getting the hardware is an issue. Proration did development on drivers but not sure what the status is. He is sometimes inactive. But that doesn’t stop me to try things on symbos. In a way I think proration will be very gladly if someone else can develop drivers too. There are examples in sources how to do it.  What driver do you need?

A Bruce EP NET card would also be good for the SymbOS driver. But the SF3 card is more important here. Net driver, access to SF3 pendrive from SymbOS. And plenty of options. Keep in mind that SF3 starts from the CPC platform, so nothing is impossible! In fact, RSF3 is already being made, so time is running out!

I don't remember it anymore, but i was on the fair in Nijmegen in 2020 (just before corona) And i thought that we had the Enterprise 128 running with G9K and SF3 interface.. but maybe it could be wrong and was it only the G9K version with the standard SD interface.. There is already support for the USB pen drive and SD card for the SF3. I can try to ask prodatron. To be honest i think it already exits but it never got released because of issues i think. I know that the Wifi interface has troubles with the multitasking in SymbOS and from my understanding Prodatron was not able to fix it with out a hardware change and hans was not able to change it in the hardware. Or at least it wasn't working together or so. There is still no driver for the Wifi interface on the CPC because of that. The hardware was not able to process multiple socket connections at the same time.. Maybe one socket connection could be an option in this case.

Sorry, I can't play with EP+SF3+G9K until September, but I can aid you remotely with the problems(easy...) that could happen in your tests.
