I have one (I think it needs a sound shield), and it works just like the 1525.

Re: Soliciting VIC-20 Internal memory expansion ideas
I use uIEC/SD, which is an sd2iec device.
I did:
@cd:ramcheck.d64
load"boot",10,1
(loads, but then no cursor)
/boot loads and I get a cursor back, but then nothing after I run.

Re: Soliciting VIC-20 Internal memory expansion ideas
Yep, loads and seems to run fine. Played around with it for a bit, making pics on the screen.

Re: Soliciting VIC-20 Internal memory expansion ideas
Sadly, (https://dateipfa.de/.Public/denial/tools/ram_check.zip) runs and then locks up. No text printed on screen. Not sure what is going on.

Re: Soliciting VIC-20 Internal memory expansion ideas
Unit boots to 28159 bytes free
detect.prg blinks and returns.
max.prg resets with 31103 bytes free
3k.prg resets with 3711 bytes free
Can't go any further until I have working COLOR RAM.

Re: Soliciting VIC-20 Internal memory expansion ideas
I noticed (and have dloaded the relevant data) your VFLI stuff, and thanks for providing that and the link. I worry that the VFLI mod (which I can't try yet, as I suspect it needs working color ram, and I don't have it working as yet) will be a bridge too far for initial testing. IN other words, if ...

Re: Soliciting VIC-20 Internal memory expansion ideas
Yep, grabbed the map from your previous posts. But, it's still unclear how I should make the 16kB relocatable across the 64kB. the default is 8,9,0,1 so should the other configs be a,b,2,3, c,d,4,5 and e,f,6,7 or Should I do something a bit more sane for the other options... :-) New board is held up...

Re: Soliciting VIC-20 Internal memory expansion ideas
If I can master the arcane memory map of the VIC-I, I will see about a production run. As for RAM, like UltiMEM, it can have access to 512kB+ of RAM, both from the VIC-I and the CPU. But, it depends on how much RAM is of actual use. UltiMEM has seen limited use beyond just being a 35k expander, so t...

Re: RAM Init Pattern
OK. I wonder if there's a way with SRAM and some of my uC stuff to read the actual state of RAM without even needing to use the save routines.

Re: RAM Init Pattern
When you say non initialized ram, are you talking about RAM before the RAM test runs? Or, are you asking for the default state of RAM once BASIC has initialized and the cursor appears?

Re: cc65 CRT help Needed
It did. Of course, now this means I need to start working the "next great VIC app", and I am sure I will run into problems when I try to determine how to make this work with UltiMEM, but at least I am off to a running start.

Thanks tons! Playing with it now.ops wrote: ↑Sat Jan 11, 2020 3:28 pm I just committed to GitHub a cart stub that I made some time ago when playing with CC65. There is probably room for improvement but I hope this gets you going.
