I know
It's a bit ridiculous, but I really didn't want to go to floppys or my little retro project, much as I love my 40 year old Apple II ones that still work.. So I'm sort of pretending an SD card is a floppy - after all, it's about the same flexibility as a 3.5" disk is...
I know what you're talking about. All that "wasted space".
For a Forth standpoint, a 16 bit Forth that is, 65MB is the peak, since you can only have 65,000 "screens" (which are 1K each).
When I think about 65,000 screens - man, that's a lot. On the other, it's a lot of wasted space (screens are simple, not efficient
).
But the key point, to me, when thinking about this stuff, and off putting to me, was that, yea, using an SD Card as a floppy (or, pretty much anything), is all well and good, but what you (I) really want is the ability to copy data off of the system. For that, you need TWO "floppies".
I have put some thought into this...
Sp plan A: Serial cable and time. (Kermit, is that you?)
Or just pop the SD card out, pop it into a handy Linux box (either one with SD card reader built in, or a USB one), FUSE mount the filesystem and off you go. Another reason I'm writing my filesystem stuff in C - just need to learn how FUSE works now...
However as I have a spare pin on my ATmega, then a 2nd SD card adapter might not be out of the question... (although I plan a 3>8 '138 type chip to give me 8 SPI channels in the next revision, so many...)
