Neo6502 / Assembler Programming

[mscha]

I want to use the Neo6502pc or the Neo6502 (I have both) to program in 6502 assembler.
Therefore, it is necessary to store programs on the USB key and to load them.

I looked in the documentation and found no solution. See a report on what I experienced below.


Neo6502pc
=========


The Neo6502pc User Manual (revision 2.0, December 2024) says:

"If you want to develop on Apple][e and write your own code you can program the firmware and the flash drive with blank ProDos disk from here. And Neo6502pc will boot as Apple][ and you can load and save your code on the Prodos disk (Flash drive)."

First attempt:
- I upload apple2e.uf2 on the Neo.
   If I now boot the Neo, I get a blank screen.
- Now I store ProDos_2_4_3.po on a newly formatted 8GB USB stick (from Olimex) and insert the stick into the NEO.
  If I now boot the Neo, I get the Apple IIe screen with the Basic prompt ].
  I can execute simple Basic commands like a loop.
  But CAT, CATALOG, PREFIX don't work and I don't know how to use the USB Key.
- Call -151 brings me into the monitor, which works nicely.
  Even the disassembler and the mini-assembler function well.

Second attempt:
- I upload apple2e-5.uf2 on the Neo.
  The result is exactly the same as above.

So, how can I store or load something from the monitor or any .asm or .bin file?
In the monitor, Axxx.yyyW seems to do something, but what? Axxx.yyyR hangs the system up.
How do I get into the ProDos environment? I tried BYE, EXIT, SYSTEM, etc., etc. No success.


Neo6502
=======


The Neo6502 User Manual (revision 3.0, December 2024) says:

'The board arrives programmed with Apple II emulator. To use the board you also need to prepare a USB flash drive with "Total Replay v5.1.hdv". Download resources from here:
https://ftp.olimex.com/Neo6502/';

Third attempt:
- I upload apple2e-5.uf2 on the Neo.
  If I now boot the Neo, I get a blank screen.
  If I insert a USB stick with the Total Reply v5.1.hdv, then the Total Replay starts with 486 games.
  I have no idea how to leave that menu properly.
  Inserting a stick with ProDos starts Apple IIe with the Basic prompt ]. CALL -151 starts the Monitor.
  How to Load or Store files is unclear.

Fourth attempt:
- I upload apple2e.uf2 on the Neo.
  The result is exactly the same as above.
