Re: Machine Code UniMenu for all platforms + new features and file archives

The Future:
I will look at putting the BBC ROM archive on SSDs for MMC & GoTek systems.
Look at incorporating the Electron Wifi system.
See what can usefully be done with ADFS systems.
However, I am now having a break to play with some hardware, lots of accessories to try out.

Re: Machine Code UniMenu for all platforms + new features and file archives

The DataCentre BBC game SSDs, STH archive, are the same as those on the BEEB.MMB but the MMC card uses disc titles which are different to the filenames so the same database cannot be used for both. I have taken the files off the BEEB.MMB to generate a set of files with names of up to 8 characters wh...

Re: Repair Advice Wanted - What do you think is wrong here?

That screen display is fairly common - often due to faulty RAM or the Electron ULA - the square chip. Holding down as suggested above might indicate the ULA.

In Beebem with the SSD loaded and write protect off you can IMPORT files, under EDIT menu, from the PC.
Similarly you can EXPORT them.

Re: Export Beeb MMC Corruption

Have you tried different ROMs.
There is the turbo one IFEL supplies and a turbo MMFS variant.
Also a standard non-turbo MMFS should work and would show whether it is the 'turbo' timing that is the issue.

Re: Acorn Torch Z80 board - No 'MCP'

I've checked the RAM which is OK.
I put in NTFS for the tube code and added a 6502 2nd processor which gave the top banner but then a star prompt and the keyboard was unresponsive. Maybe a tube problem.
Thanks for the suggestions but I'm putting this on the back burner now.

Which other ROMs do you have in there? 'No Room' suggests it can't allocate enough space to run MCP, ie. PAGE is too high.
No other roms, just BASIC, MCP & DFS.
Another attempt and *CPN gives MCP then it hangs with no attempt to access a disc.

Acorn Torch Z80 board - No 'MCP'

I am trying to set up a Torch Z80 board.
The MCP120CBL rom appears to be active but from another thread the header should finish with MCP not BASIC.
The FS is DFS 0.9, there is no Z80 attached and the DFS is active.

Thanks Dave, that has got it all running again.
I had extracted PTD from the zip again and forgotten to edit cmdline.txt
It suggests that the original problem was a corrupt cmdline.txt or faulty processing of it since originally it had been edited to set elk_mode=1.

Another bugfix - the database had about 20 entries without the correct termination for the USB directory.

The instructions for SST don't include any reference to entries such as:

SST expects the text after SST to be the name of the ROM file or ^ to indicate use the data in memory at &3500, it will not process *DISC it will try to find a file named *DISC.
