I have produced a menu and a BBC+Electron file archive for use with MMFS2 here viewtopic.php?f=3&t=21511&p=304584#p304584
Ray

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.

The zip files are available from http://rayharper.co.uk/UniMenu4R/Stardot.html 1. ElkGoTekSSDall.zip Rom SSDs in one sub-directory, Magazines each in their own sub-directory and games in 23 sub-directories. Electron ROMs includes MMFS1P48.SSD with all of the Electron MMFS/MMFS2 files renamed without...

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...

This UniMenu, UniMenu4R, is a development of the MODE4 version in machine code with additional features: 1. Not asociated with particular databases - loaded as required. 2. * commands, primarily for navigating directories. 3. Display of text files from a database with the new 'T' action and also fro...

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. If it is not soldered - carefully remove and carefully clean contacts with IPA. If resistant to the above you might need to send it to Dave Hi...

I have used TreeCopy to backup an ADFS HDD on a Master to an A4000 fileserver (ADFS obviously) over an Econet. What I remember is that the syntax has to be exactly what it expects and it took me a while to get it right. Probably need to include :0.$.SourceDir-- etc. to :1.$.DestinationDir-- Can't re...

I guess if perforations are needed the user could add them or cut out the section for the ZIF socket with a Stanley knife.

Thanks everyone that is very helpful. It's reassuring that I was thinking along the right lines. Gerald's code explains something that was not clear to me. In books on assembler EQUS statements end in the EQUB 13:EQUB 0 as in Gerald's code. I had not understood why the zero was there since you can d...

I am trying to rewrite one of my BASIC menus in assembler and need to CHAIN files. I have tried OSCLI which not unsurprisingly gives 'Bad Command' since it is not in BASIC and not a star command. I thought it might be possible to put *BASIC and the CHAIN ... in a function key but I feel there must b...

With my uv erazer I only use about 12min.
The instructions recommended increasing the time till blank then using that time.
I don't know whether 'too long' might be a problem.

How do I now add program files into the new SSD please?
TIA.

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.
Ray

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.
Ray

Yes, 2 for me.
Ray

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.
Ray

MCP is there in HELP. Connected the board.
*CPN gives 'User program error - 01'
BREAK gives 'No Room for MCP'
Ray

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.
Ray

Thanks for the image Dave, Having fitted the AP5 in its case I had forgotten the connectors 'hidden' on the rear of the board. I have drilled a 4mm hole under the 1MHz bus connector and made it slightly oval with a 3mm bit and a file so that 2xDupont cables can fit through. It can now power an ADFS ...

If anyone wants one of these boards (?) the hole could probably be filled with silver loaded epoxy to form the +'ve connection. Let me know - FOC - I'll even provide P&P . . . Silver and copper powder appears to be available for a few pounds - not sure which would be best, probably doesn't matt...

Hi Dave,
Is it possible to modify the first AP5 so that it has a 5v output?
Ray

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.
Thanks again,
Ray

I had my Electron + Plus 3 + GoTek second drive + Slogger RomBox+ fitted with both: A: Tube cartridge + RPi-v1 + level shifter & PiTubeDirect FerdeLance and B: ElkSD64 cartridge which has MMFS 1.44 printer port version. I could run Z80 second-processor software with either system: A - with ACPDF...

I have used a 1.5m floppy drive cable without any problems.
Ray

I have a Viglen BBC with Econet, Viglen cartridge adapter and a 2 speed fan. I love the separate keyboard.
Ray

I'd like a built-up one.
Ray

I have recently constructed a ROM archive for the BBC during which I came across an archive containing many Slogger Electron ROMs. I have combined these with others I had to hand to make an Electrom ROM archive of 97 ROM images for a tweaked version of UNIMENU, UNIMNU4B, which will run from a HDD or...

UniMenu7 Big Bug fix - after a search the rom image would not load, now it will and the menu is also 6502 second processor compatible. Both USB and HDD versions are in the zip.
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 *DISC MYROM &D
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.

Ray

It should be fairly easy to copy the SST to the disc image with the ROM images. Start with a blank DFS image. Copy the utilities to that. *INFO SST to find the load address and length of the file. *LOAD it. Move to the GoTek disc image with the ROMs. *SAVE SST loadaddress +length If you need any of ...
