great.
Do you still need your (mounted one) own?

I have added a blitter to my 520ST. In fact, the PCB's arrived from china just today so I was quite excited to see that it actually worked! Of course, the sane thing to do would be to just get an STE, but I like this machine - I've had it since 1985. Thank you Exxos for stocking and selling loose B...

nice document

ther you can see working ATARI CDAR504:

yep, I know, I have dead 1040 STfm motherboard with an empty blitter spot.
but short 520 ST is more sex IMO

Got it!

Artik-wroc, my colleague from Atari.org.pl forum, sent me an article from ST-Computer Issue form November 1988:

and screenshot below.
Based on them, some years ago he did BLiTTER's daughterboard for short ST.

Thanks Exxos.
I used a lot Zero X on ST and and later on Falcon

Didn't even know yahoo groups was even still going. I don't know of anyone who runs any groups. I run the old atarimusic site, but thats on its way to being taken down.

atarimusic.net was run by you? nice

nice, we can use then the BLiTTER to copy data to the data register.
I have one concern about the price:
https://www.buydisplay.com/default/seri ... 76-for-due
$68 only for that module and probably should be added/buy an interface between ST and that module

Everything will have to go through the registers of the RA8876, but then high level drawing operations can be implemented using only a few writes.

what about bitmap graphics? is it possible to push it somehow to the RA8876 RAM? and how fast?

great
