Does pressing BREAK after mounting the disk image help at all?

(You need to do this on a real Atom)

Makes no difference sadly

Carried that out step by step but end result is the same i'm afraid.. "Not Ready"

I placed the file in fat/Games/AcornAtom/boot.vhd on my main SD
and then selected it from the menu

Thanks Dave, will try now

The Not Ready error from AtoMMC occurs when the AtoMMC Firmware (running on the embedded AVR/PIC microcontroller) has been unable to initialize the SD Card. I'm not sure how this works in Mister, but in a real AtoMMC this usually occurs if there is a fault in the SD Card interface, or the SD Card i...

Thanks Dave I will give it a go

Merry Christmas

Thanks Dave I uploaded the file renamed as boot.vhd firstly as is with no files added. Still getting the Not ready error when trying to *CAT it Used WinImage to inject the Atom Software archive but still getting Not ready error I'm assuming with the new release that the VHD file goes into fat/games/...

I have the latest core downloaded to my MiSTer FPGA system, created the AcornAtom folder in the Games directory and proceeded to create a boot.vhd file containing the archive but for the life of me cant get it to run. keep getting the Not Ready error.. Does anyone have a compiled vhd ready or can he...

Cheers Dave, I will post in that thread

I've got one of these fitted to an Issue 4 board and with the 4MHz feed soldered to a different source works very stable. Shadow RAM works fine too and the TESTRAM command tells me all is good. But for the life of me I cant load any Rom images to a sideways Ram bank whatever method I use.. The onboa...

Already been through that, all checks out lol

Well All Via's are good, all tracks confirm good. Cant find any shorts. What I can confirm though is that the 2nd ROM socket, controlled by the right jumper block does not allow the SRAM to be mapped inplace of part of the Pegasus DFS ROM, so although fitting just the DFS ROM in the 2nd socket I can...

I will check the vias out today Dave... Just confused as to why the ADFS ROM stops the DFS ROM being seen when its plugged in. Removing the ADFS ROM sows DFS in slot zero Plugging in ADFS its seen in slot 1 but slot zero is now empty. All disc functions work perfectly when either rom is active.... Doh

Started looking into this this morning chaps and found some funny results lol The board is configured as follows 28 Pin Sockets L-R are PEGDFS , ADFS, 6264SRAM, 1772 Jumpers L-R are D, U,U,D Which seems great.... Plug board in and ADFS works absolutely fine... DFS Rom is not even recognised by *ROMS...

Hi everyone Thank you so much for the support... finally saw the link for the schematic lol I built 2 boards, one works perfectly ADFS and DFS the other has this ADFS issue, jumpers set the same on both boards. Pretty sure I have a trace or via issue but thanks to the schematic should be able to fix...

Cheers Colin

Cant see a schematic anywhere though ?

Hi Guys

Would anyone have the schematic for the Acorn Electron Pegasus Disc Interface Please..

I've got one here working perfectly with DFS but fails to Recognise any ADFS ROM.

Bas

Thank you oh Genius

Cheers Dave

I'm rebuilding the project now, 363 warnings but no errors lol.
Have to work out how to add the VideoNULA bit you branched

Thanks

Hi Everyone Just Got my ole DE1 out of storage and aching to loadup the BeebFPGA package with M5000 support. It's been so long though and I cant find my original downloads. Can someone please upload or link the latest release for the FPGA and ROM files :) a Gentle poke as to how to loadup the ROM fi...

Looking Fantastic Phill

Congratulations Phill,
I knew you would get there

Looking forward to testing a board in my Atoms

Phill,
This is looking awesome, can't wait to upgrade my card

Thanks for persevering

Hello Everyone Firstly Apologies to Phill and anyone else awaiting a new run of DragonMMC Boards As some of you are aware my family and I have been planning and arranging a move to Corfu in Greece over the last 12 months and since Jine this year it has taken priority over most things. I'm Pleased to...

And replied
Thanks

5 Left to ship.

This is the last batch I will be building so last chance folks

No Takers chaps...?

7 left in stock

Hi Marcus Sorry for the late reply.. Indeed, I supply SmallyMouse2 with all Interface headers installed as standard so you can share the unit between 8bit and 32bit Acorns, just need to have both interface cables. I have a new batch ready to ship, drop us a PM if you would like one with cables. Rega...

Have you tried swapping the 6522 chips around ?

New Batch for 2018 Now Available for immediate shipping
