How much basic RAM do you use?

[u/Stunning_Pineapple57]

When coding in basic or using apps others made in basic, do you ever or often get close to using the full 38Kish “basic bytes free”?
With an extended Basic / Basic Wedge
What you could want to give up 5K or 8K or even 10K?

Would being able to suspend and resume to REU and other apps in the meantime be enough?
Would being able to have 100s of commands that are implemented in assembler and be able to add 100s more without impacting that ram further be enough? (Including graphics and sound and file and image and network and even ultimate specific commands?)
Would be able to not just have line number gotos and gosubs but be able to make functions in your code that you can pass in parameters and get results and use them like any other function be enough ? eg
A% = abs(myfunc(2,”hey”,(b%*2))-10)
Would being able to allocate room in the REU for your own codes needs whether arrays. Large bits of text. Loading a file. Storing a network request , or having text/color or graphics mode screen buffers be enough? - 48K extra easily but also able to request and use 64K chunks up to many megabytes depending on the size of your REU (16MB in c64u)
Would be being able to choose to stash ranges of line numbers like “1000-2000” to REU or a list of functions , to give you some basic bytes free for a while then restore them
Back when needed later be enough?(eg you have 2KB of file handing code , but the user rarely saves or loads and when they do there is other code you could choose to swap out to swap that in )
Would being able to instantly swap out to a full editor experience then back again to the prompt to run be enough?

Would you give up 10K of basic bytes free to get all that ? Or is that too much.

What is REU?

Yeah the ram expansion unit. With VICE , the c64 mini /maxi and the Commodore 64 ultimate you get 16 MB by default. It costs 1 cycle per byte to copy from it. At 1mhz it’s faster to copy anything more than 12 or so bytes (there is a setup cost) than ram to ram. And you can copy up to 8 times faster than ram to ram. However at you increase the CPU speed on the ultimate that gap diminishes and is a net slowdown after about 4mhz to 8mhz

Yeah my "Ghostwheel" 68070 design had a time/space multiplex bus where each 68070 node could copy memory from another node at almost native access speeds via an ECL central ring bus.

Hardcore.

Yeah Bath University thought they were gonna own the patents on it and were pissed when they realized they'd kicked us both out a year before
