The MTXduino is similar to the Casduino/tsxduino on github, which is an open-source project I believe - you can easily build one just like it with some moderate electronic/programming skills ;) .. I printed my board because I had a bunch of designed boards at the time and just wanted to make the ord...

Thanks Steve .. yes, it was great to get that rare FDC05 clone working! .. many thanks to Dave and Tony B (the original designer) :) I painted my MTX yellow because black is boring .. :lol: The LCD you saw earlier, is my own-designed MTXduino wavplayer (similar to Casduino) .. I only built 2 units o...

..The only related entry points I found in ROM sources were these: basic -- #259 basics -- #205 -- new page/reset basics1 -- #244 basics2 -- #250 basics4 -- #24A ..and dobasic .. #2116 , #2118 what I'm trying to do is .. read bytes from the SDX floppy in assembly .. or hybrid (assy/basic) method.. i...

Thanks Bill,

Yes, I looked at Resource2022 before, couldn't find entry points related to calling the basic interpreter..

the ROM sources are interesting .. I will search through it and hopefully find something

how would you call the BASIC interpreter to execute a command from inline assembly ? something like this .. 10 code 4007 LD HL, Command ; HL points to the BASIC command string 400A CALL #2400 ; Call BASIC interpreter to execute the command 400C RET ; Return to BASIC 400D Command: DB "PRINT &quo...

..never mind .. i found my answer recompiling the sdxrom from source and removing that 16k limitation per Andy's site..

.. after Using SDX07 file system recently, I have noticed a file-size limitation for data stored on disks , the file chunks can not exceed 16k (#4000) apparently, CP/M 2.2 has a limitation where files are divided into 16K extents, and the file system can manage up to 512 extents per file in total. C...

That's very cool

You have done a wonderful job Dave thank you ... and now with that mistake FIXED on the schematic by the original author Tony B, that was invaluable.. "Memotechers" can now build and enjoy that rare FDC05 based on your schematic .. I do own a CFX too btw .. but who doesn't like the clicks ...

Guys, it works !!! .. that was it, Thank You! Dave, a few notes below that might help other future builders of this PCB: (reading this post in the future) I have tested on 4 floppy drives I already have .. all drives were DS0 modded of course.. the drives that worked: 1-The Sony (of course) MPF920 2...
