Older storage would be a self-imposed challenge for developers who want a taste of what developing in certain eras was like (but I agree that they won't be common on the X16):

Tape: Data can only be loaded once (unless you ask the user to rewind), and always arrives in the same order. You sometimes have software control of the play/pause function (i.e., for pausing the tape while you process the data that just came in), but if you use it, your software won't load if the user has a cassette player that doesn't support this.

Floppy Disk: Data can now be randomly accessed, but limited space means data must be spread across multiple disks, and must be organized in a way that minimizes how many flips/swaps the user needs to do throughout use.

CD-ROM: Much more storage space, redbook audio is now available, but this media is read-only. The previous two mediums provided the user a way to save, but CD-ROMs are read-only, so the user must fall back to another method if they want to save data.


Current mediums:
ROM cartridge: Data is instantly available and doesn't always need to be copied into RAM. Components can be added to allow save data to be stored directly on the cartridge.

SD card: Lots of space, fast loading times, random access, read and write (optional write-protection), modern computers support them so it's the most hassle-free way to transfer data between a PC and the X16.

Network card: Hmm, watch this space.

While CD ROM (and perhaps DVD) support sounds like a good idea, there is a draw back that not many modern computers can not create content on these media types these days, since drives are no longer a standard part of a computer. They can be ordered as an extra option by some manufacturers.

No media type is immune to degradation, just like no online opinion is either. :)

That being said, someone might pursue building an optical media interface/system for the X16. That's one of the minor goals - users can adapt and build on the system in a relatively easy way (as compared to a modern slot such as PCIe.)

Optical media may not be standard for most computers but it's still pretty easy to get them as a SATA option. I have a newish Ryzen 7 board and prebuilt system and I made a point of ordering an DVD/CD burner preinstalled. (The board came with another surprise for such a new board. It has a P/S 2 keyboard port as well).

Agreed - at one time a CD drive was more or less a requirement as most OS shipped on CDs and SD cards were 32 Mb. For the mass market an optical drive is a "retro" thing.

Kinda neat - you'b be able to plug your X16 keyboard into it :-)

Can I ask what is CCDA?

CDDA = probably the acronym of CD Digital Audio. I think what's meant is that you should be able to play audio cd's on the hypothetical add-on.

Assuming the existence of a Drive to read CD-Roms to the X16 it would be relatively easy to implement CDDA on top of that, as long as the transfer rate was at least 150kb / s ( 1x CD-Rom speed ). It would be hard to make that background though without some sort of cpu on the interface card itself.
