I saw a revision 0 on eBay last week, probably the same one that many others
saw. And I noticed it didn't have the whole 48K installed. It was a 16K
machine. I also noticed, and probably others did too, that it didn't have
the Programmer's Aid #1 ROM installed, nor did it have the (I presume)
Applesoft ROM card which is mentioned on the handwritten sales slip.

https://www.ebay.com/itm/165434130293

That made me wonder whether there's anyone out there in Apple II land who
still maintains a sub-48K Apple II? I'm guessing that's an incredibly small
number of people, if any. It makes using DOS trickier, for starters. I think
16K was the minimum RAM size for DOS, but then how much RAM did you have
left over for a program?

And what about the base, 4K Apple II configuration? What did anyone manage
to accomplish with a 4K machine? No HI-RES graphics, for sure! Anyone here
ever use a 4K Apple?

It blows my mind to think of a 4K apple II. I know they were offered
in the beginning, but that was before they had a DOS. Can't image you'd
be able to do much on a 4K system.

I've never checked all my II's and II Pluses, to see what they are
configured, but I suspect most of them are at least 48K.

Well starting around Rev 4, the RAM selector blocks were all fixed at 48K,
making it difficult to have any inferior RAM configuration. My integer Apple
II has a Rev 4 board, with a handwritten date code of 1980.

But my Apple II Plus has a Revision 3 board with removal RAM blocks. It's
dated early 1979 (if you have The New Apple II User's Guide, you have a
photo of this motherboard).

Quite a few of my II/II+ started out at 16k but have since been upgraded.
Occasionally I've pulled out a 48k machine and used it for a bit.

We fit a Wordle clone into 16kb.

A 4kb machine would be limited to text and lo-res. That limits things a bit.

Just read your overview on the 'Hub. "It is all completely ridiculous." I
bet reading your 6502 source and learning about the data structures involved
for storing the word list is more interesting than playing the game. ;-)

:-) I like the game, but I enjoyed this coding more, even though I just ported the compression.
4am wrote the text and most of the code.

Mine came as a 48k unit in 1981, with Apple RAM. The vendor I bought from, not long before Apple did its first crackdown on online sales, charged a $100 increment from 16 to 32K and 32 to 48K... I remember seeing the Apple branded 16K upgrade kits for 16 and 32K systems at my local dealer for something like $200. It was "Not Cheap" (TM) to upgrade back then.

But when the initial Apple II was released, some of the competition was still the AIM-65, SYM-1, and KIM-1, some could be had with as little as 1K of RAM. It was enough to learn on and probably exceptional for learning to program efficiently and not waste bytes. Getting a 'full' keyboard and video out with text any kind of graphics at all! on a 4K system was pretty nice back then.
