I suspected as much. If it was easy I'm sure you would have done it already.

Re: RGB to HDMI using a Pi Zero and a small CPLD

That's usually caused by the *TV setting on the beeb/master I had a Doh! moment with this one. I was using the menu screen from my TurboMMC card as a MODE 7 test and discovered that the !BOOT file had a *TV255! I'm surprised it isn't cutting off modes 0-6. After a bit more testing I realised that w...

Re: RGB to HDMI using a Pi Zero and a small CPLD

I think I've fixed the bottom line being cut off by tweaking the V Offset (32 for mode 7 and 36 for the others).
I've got some twinkling in mode 7 with a red background. This seemed to disappear at some points in the calibration but returned in the final result. Any suggestions?

Re: RGB to HDMI using a Pi Zero and a small CPLD

I've just built my kit and fired it up (without the 12 bit adapter for now) and all seems well except: 1) Integer scaling works great in modes 0-6 but in mode 7 most of the bottom line of text is cut off. Auto works fine but does not fill the screen as well. 2) Genlock is inhibited because the monit...

Re: For sale: RGBtoHDMI boards

Sorry Ian, not sure if I need the 12bit extender for use with a BBC NuLA now. Re-reading your post it sounds like its only to bring the 12bit video out to an external connector. Can you confirm please. If not needed then take the extender off my order. Thanks.

Re: MMFS Development and Support

What formatter were you using?
I was using SuperForm which is the standard Winchester Disk formatter.
No worries, I've made a copy of the blank and renamed it scsi1.dat etc. which works fine.

Re: MMFS Development and Support

To try to eliminate the BeebSCSI pseudo hard drive I attached my floppy drives and formatted a floppy in ADFS format. Attempting to *MOVE a file from MMFS either results in a 'Channel' error or 'Disc fault 18 at :0 00/00' which is odd since I'm trying to move to drive 5. Drive 0 is the BeebSCSI hard...

I found that FD00 doesn't print anything if the tube is active, with NOTUBE I get virtually the same output as you. I actually rebuilt the Pi1MHz kernel this morning so the dates are different. The move still hangs, I can only assume the file is corrupted in some way which is upsetting *MOVE If you ...

Re: MMFS Development and Support

I've tried running the move with TUBE on and off but it still hangs.
I'm running MMFS 1.44
The BeebSCSI is running on a PiZero
Printing FD00 produces nothing, which I'm guessing means that I don't have the latest firmware.

Re: MMFS Development and Support

Has anyone had experience using *MOVE to copy files between MMFS and ADFS?
I successfully copied one file using:

Code: Select all

*MOVE -MMFS-:0.$.filename -ADFS-:0.$.LIB.filename
but the next time I tried to copy a (different) file the *MOVE command never completed.
Any ideas?

Re: Wireless Printing

I guess you could download files but I haven't written the code for that. The D1 can be programmed like an Arduino and there are libraries for connecting to Wifi etc. I could attach the complete code if you're interested.

Re: Tube coding 101! Help wanted please.

I believe my code runs on the I/O processor. I'm redirecting WRCHV (&20E) to my code which simply does STA &FEE2, JMP OSWRCH.
I've just tried ?&FEF8=65 and that doesn't work either.
