#AtariSTe simple SD card reader via the extended joystick port, I made the driver using xbios functions hook up to simulate a drive, so you can browse your FAT 16 SD card up to 2Gbytes using bigdos directly from the GEM desktop ! youtu.be/2COG26-XjC0

Well crap.

I wonder if we can do similar on the Amiga (:

Mind you, I um, don't ... I have a CF ... thing... I should stop now because I have enough projects I can't get to (:

@Truck @mmu_man @zwangseinweisung @_Adoru_ the extended joystick ports on Atari STE act a bit like GPIO ports so that's why you can make something like that. But it won't use any DMA, it's all on the CPU. Advantage: cheap, drawback: slow.

On ST it's better to use an ACSI-SD adapter like the UltraSatan. But it's a bit more expensive (~80€).

@Truck @mmu_man @zwangseinweisung @_Adoru_ Note that most of time, the fact it doesn't use DMA won't really be an issue, since there is no multitasking on TOS/GEM (every disk access is a sync call). But for this demo, well.. I used the DMA to parallelize the loading of data ;)

Actually the disk DMA is very fast and takes priority over the only other DMA access, which is the ST's blitter.

I need to get a MiSTer ... like... soon (:

Fun fact: Bad Apple is not a Demo (:
( youtube.com/watch?v=joXyj0q3LF , for some reason I can't get this to show up on invidio.us ... )

(I assume all of y'all will be watching Outline with me this weekend? I'm sure there will be some very interesting ST things released there, I hope to see some MSX too (: And _maybe_ someone will do an Amiga thing, even though it's sort of silly to do that (: )

@Truck @zwangseinweisung @fenarinarsa @_Adoru_ I guess the only answer to this would be an ORIC Bad Apple… 😅

@mmu_man @zwangseinweisung @fenarinarsa @_Adoru_
NO. And I am NOT going to ask Dbug to do that (:

(Sadly, I wont see Dbug this summer ): Haven't seen him for a few years. But I _do_ have an Oric! (: )


@Truck @zwangseinweisung @fenarinarsa @_Adoru_ yeah I recall seeing it on your last live.
Well, I could probably do it on ORIC but it'd take me a few years.

Given that Dbug's toolkit is basically windows only, yeah.

I have ... wanted it not to be, but... well, he DOES do development mainly in Windows (if he is still at Funcom, which I _assume_ he is.)

Personally I think that's half the reason he's the only one doing ORIC demos, but... well, that may also be partially because one of the other major people who did them passed away a number of years ago (Twilite, who gave me my ORIC.)

@Truck @zwangseinweisung @fenarinarsa @_Adoru_ no no, I fixed it for Linux long ago, but I never took the time to package it, so I'm basically the only one using it :D
