Awesome! But it is a lot of work for you alone.

Hardware / Re: Maxduino / TZXDuino compatible with enterprise? Also, TAP file archive?q

There is no problem with cassette loading on the EP, it has two loading/saving speeds and the volume can be easily adjusted depending on what you see on the right upper corner, one green and other red rectangles, that will flash alternately on the optimum gain at the leading tone.
I used Tape input a lot on classic days, mainly for the lack of a floppy controller... Once I got the EXDOS controller I rarely have thought about Tape...
But the designers made a great work, every file has a header, like on other computers, and the main file data is divided on 4KB chunks, each one with its own checksum. When an error is found the loading is immediately stopped. To manage the loading and stop pauses between chunks, both the Tape IN and Tape OUT lines have remote jacks with mini relays. This was very useful for me in the past.
I still have not tried a Maxduino, but maybe the chunk feature on the EP is what will not work.

Poking, again, inside the packet of files about Entercom(Enterprise BBS), I have found a key-word: K221.
It seems to be the hardware used on the Bugtronics modem card. Inside the datasheet there is this schematic:

I have seen, poking on the EXOS Rom with an Hex editor, that there is some Basic code on it. How big is the Basic Rom really?

Excessive and extravagant! Largely out of the hopes of the designers....

Great work Bruce, and thanks for the advice about IS-DOS.
Yesterday I made 4x2GB partitions on a SD for the FPGA Enterprise core and they seem to work, but I need to do more tests on them.
Again, like with the FAT12 format, Windows fails sometimes to make good FAT16 partitions.

I am actually beta-testing it and... YES.... EXDOS3.0 works great on the emulator, both with the emulated SD-Cartridge and with the emulated IDE expansion. It also works perfectly on the real EP+SF3 when used with the new driver that integrates the SF3 USB as a logical drive. And other device that uses EXDOS30 perfectly is the Enterprise FPGA core, thanks to the mastery of Kyp implementing correctly the SD-Cartridge and using the same Roms that genius Zozo provided me for use on the emulator.
On the other side, the firmware of our SD-Readers needs to be updated, because the SDEXT0X.Rom in them needs to be updated to be compatible with EXDOS3.0, and also because the firmware is fatter and needs more space. A SD-Cartridge has an, until now, unused memory pagination that adds another 64KB(8KBx8) to the cartridge. Think about it... a pagination inside the normal Nick's pagination...
Complicate task... more if we think that Zozo will add languages and keyboard pre-sets on the SD-Cartridge.
Now you can have a very big FAT16 partition with all your things on directories without delving with tinny 32MB partitions, and at the same time it makes easier to transfer your files.
The boring side is that it works as good as always... You will not notice any mayor change on your EP behaviour....

Ok, I have managed to take this short video with my phone on my left hand while I was playing with my right hand on the little screen.
The idea is that the RSF3 can also work stand alone, not connected to the host computer.

The touch screen allows better control of the inner settings of the device. For example, romtables are set doing clicks on the screen, SID player, FM player, are like apps on the screen.
Maybe a video would show better how it actually works.
Later.

The original Bactron game was released protected on disc or tape. I have found this cracked-protection version that even has some errors fixed.
I have tested it on Geco's CPCEmu, and it runs and loads some image, then it hangs. It probably access the hardware directly when doing a moving horizontal bar effect just at the beginning(not begging...)
