FPGAARCADE minimig compatible board, comments?

[mikej]

The video out is sort of complex.

There is a link which selects 15K/30K scan like the Minimig board - basically "TV" or "VGA" mode. This lets you at least see the boot menu on whatever you are connected to.

If the composite/SVHS out module is plugged in, then it only works in 15K (TV) mode.

Whatever mode it's in, the analogue output come out on the DVI analogue pins, so you can use a DVI to VGA / SCART adapter for TV or VGA monitors - same as the Minimig.

The digital signals also always come out the DVI pins. If the refresh rate is 50Hz then some computer LCDs won't display it - but if you use a DVI to HDMI cable then LCD TV's will work nicely.

Most LCD TV's will only accept 60Hz on the DVI/VGA input, but are happy with 50Hz on the HDMI / composite / SVHS inputs.

Best,
Mike.

@Mikej,
Any updates about the replay ?
It's a bit quiet here !

[mikej]

Hi,
yes - I've been on holiday for the last two weeks. I'm now in China and will be back to work on the Replay bring up as soon as possible. Several boards are with other developers who are also making good progress

Great news. I look forward to an update!

p.s. Does anybody have a 68EC020 processor I can buy / have? A broken A1200 main board would be a good donor if the processor is good.
/Mike

pm me a postal address i can send you two desolder ones for free if you still need them.

i also have freescale 68EC020 25Mhz if i have a spare i also send one. (max two processor). free no cost.

NOTE: if you only need one just say as i can save the other for another amiga user.

[mikej]

Delshay,
Thanks, a kind offer but I am ok for now.
I got hold of a 68060 and a 68030 as well so I am good
Best,
Mike.

Mike >> You rule.. amazing work...

[mikej]

I've put some pictures of the LCD board and IO board up on the website.
I should probably stop playing with the LCD and focus on the main video output

Tentatively put me on the list.  I can't commit without a price and the wife's consent, not necessarily in that order

[mikej]

When I'm happy with the board design (and hopefully got the new website with forums up) I'll open a list of all those who wish to pre-order. Aiming to push the order button mid to end August.

Awesome work Mike, can't wait for this puppy to be on sale

For us Amiga user's what can we expect, for example what will it support when first released (OCS/ECS 030...060)?   What about the future, any ideas on timescales for AGA, AGA+?

I guess you'll be looking to external developers to come up with softcores to support AGA?  I think Jens has already cracked that one but he might not be willing to share as your product *may* end up as a competitor to CloneA depending on how it is marketed.  Hey, maybe you should talk to him to see how he feels about some kind of collaboration.

[mikej]

The Replay board is more of a platform, so it will support many different cores from different developers. The boot structure is designed from the start to make this easy.

I'm really an FPGA person, so once the hardware is up and running I'll maintain and enhance the Amiga core. I'm working with a few other people on it as well.

You can expect initially the board to behave like an ARM enhanced MiniMig with more RAM and DVI, but the short term aim is to get a 68020/30 softcore and enhanced video so ECS level at least. AGA may not be the best way to go, the hardware can do much better but the problem is driver/software compatibility.

Good stuff, I can't wait to see the results!

Jens (who is also working on an FPGA OCS/ECS implementation) was quoted as saying that it wouldn't be much extra effort to go to AGA once you have ECS cracked.

Anway, best of luck with this one

Got a rough idea of price yet Mike? Worse case scenario?

[Retro_71]

Put me down for one.. the wife is really going to kill me but who cares....
just a quick question after the first release how quick will the extra items appear and in what order?
Now just hope it not to expensive. how easy would it be to change cores (what i am trying to say will one be enough to have a amiga, Atari, VIC 20 machine?)
