SDRAM_rev board will become obsolete and incompatible when 4.0+ I/O board will be released.

The main SDRAM board design is SDRAM_uni v3.1U or older SDRAM v3.1.

Horizontal inward direction won't be supported if you will need new I/O board.

I'm just starting out on MISTer. Have assembled an V3.1R board today (horiz-inwards IIUC).

Is there any public information about your plans for the future V4 io-board at this stage?
I'm not asking for a timeline, just trying to gauge in what direction things will be g(r)o(w)ing...

(with a big thanks for all sharing all your efforts!)

Latest I/O Board is v5.2. Newer version of I/O board includes features of older versions. So there is no plans to develop v4.x anymore as it's superseded by v5.x

Ah, of course - I've been reading up on the other threads. Ok, all clear now.

And the SDRAM board is working perfectly here at 140 MHz.
Thanks also to the excellent beginner's guide on the GitHub wiki.
Enough for some beginning MiSTer core explorations. Great!

Just a quick note: Inward SDRAM wount work with new I/O board 5.2. It covers the area used by SDRAM board.

Yes, found out after I had placed the order at OSH-park. No prob.
Plenty to try out - I'll probably hand-wire an SD card to try the other cores.
Thanks for the heads up.
