Dear All,

I'm new to this forum.
I have the same 520 ST as mentioned in this post and upgraded it with the 4mb Exxos kit.
I was looking for a nice HD solution and something with a TOS upgrade and found the project from Mr Granlund.
(Was following his Scummvm port and found the project)
I have basic soldering skills. But this board seems doable. :)
A friend gave me some Atari IC"s and I think that one of them is a blitter.

Based on the files I have ordered a PCB. I will received 5 (minimum order quantity).
I can give some away for free because I only need one. Maybe I need your help during building and installing.
So a PCB for some tips and tricks later. (the PCB's are not yet in)

Regards,

Nice! More Blitter love for the short ST :)
Looking forward to hearing how it works out

You can get one for free if you want. I don't know much about electronics or hardware.
So the price is not to say RTFM when I ask stupid question which every Atari guy should know. :)
I took the Gerber files googled PCB production and the dumped the files on a website of a company in China (JLCPCB).
So I hope this will work. It said 4 layers and the preview picture looked correct. When I have received them I will post a reply here. I think it will take at least 14 days.

Yes I love my tiny ST. Thanks for designing this Anders. I hope I can get it running. Then I can try Monkey 2:)

So here's my first stupid question.

I assume this is a Blitter chip which I can use (MM9092V)?

Yep, MM9092V is the one I use as well (bought it from Exxos)

Although mine is marked S9006 and I have no idea what the difference is between that and your S9106AB, different revisions maybe? I'd assume they all have to be compatible though.

Ok thanks.
When googling the number I did not get any hit so I wasn’t sure.

Hi,

Today I send the board to you. I send it as a letter. So I hope it arrives.

Good luck with building it.

I’m now at this stage. So need to remove the cpu. My friend who has a nice desoldering station is on holiday so probably will be stuck now for some weeks.
