Cool - uA1-I piccies... yay!

(Edit - get in there! I was first! ) Now to move my comment from the BB2 thread to here...

@whoever can answer

What's with the bent pin on the two sets of headers (one at the port-end of the PCI slot, and one to the left of the heatsink) - I originally thought that someone had accidentally bent the pin connecting something, but as there's two done the same way, it must be deliberate... but why??

According to my calculations, a standard CF card will overlap the edge of the board by about 13mm (i.e. about 7.5% of the width of the board) - not a good design! Is this intentional, and how the final board will be laid out, or is it just a quirk of the early prototypes?
I determined this using image 3; the CF slot on my screen is 110mm wide, which is the equivalent of 43mm wide in "real" terms - i.e. the width of a CF card. The space available to the edge of the board on-screen is 60mm, equivalent to a real measurement of 23mm, yet a CF is 36mm deep, leaving the card overhanging the edge by 13mm. Quid Erat Demonstrandum. I think; it is quite late, though...

Can anyone tell me what the left-most port is on the back of the board? I don't recognise it - well, there's nothing like it on the back of my PC, anyway! Is it a TV-out/S-video, or summat??

Why is there an empty socket on the board, next to the Sil0680? Looks like the FPU socket on my old Blizzard 030! What's it for?

What's the black connector next to the PCI slot?

What's the story with all those jumpers on the board? I've never seen so many - tha's gonna be complicated and fiddly to set up, I fear! There's a cluster of them next to the CF slot, and another batch up near the parallel port... bizarre!

What do the two LEDs down by the CF slot indicate? CF data transfer? Board power?

What's that strange thing above the LEDs, between the jumpers and the CF slot? It isn't very clear on any of the photos...

Most importantly, however - it doesn't appear to say "Amiga" anywhere on the board; why not??

@chunder

Maybe someone figured they need some space for some casing as well?

That certainly looks like a svideo connector to me.

As for no "Amiga" print anywhere I guess there is nothing Amiga about it except that it can run OS4!

Nice pics guys. Hope you have fun!

I got a 404 error in some image links.

Nice pictures guys.

Is this a prototype board or the final version? Very nice regardless.

Thank you!

Heh, I notice the Sil0680 IDE controller there, bypassing the evil VIA rubbish.

Why is there even a VIA chip on the board anymore! :p And why is it the 686B and not a more recent chip - even the Pegasos uses the 6231 (PCI variant of 6233).

Still ... mini-itx, graphics, firewire, 5.1 audio, memory, PCI ... more than a pegasos in less space!

When will they be released?

The bent pins are probably not supposed to be there at all on the final production run. They are keyin pins to prevent you from hooking things up backwards. I'd say that at least one of the headers is probably USB which normally comes as 9 pins in 2 rows.

The CF slot is not a push button eject slot so if it didn't overlap the board you'd have a hard time removing the CF card. It's not bad design, perhaps cheap.

The left port looks like the S-Video port on the back of my DVD player.

The empty socket is most likely for commercial customers who wants to add their own boot rom.

The black connector next to the PCI is a PC-104+ connector, sometimes also called PCI-104. It is basically for industrial PCI cards that mount flat against the motherboard.

There is no parrallel port, the port above the jumper cluster is a 15 pin game port. The jumpers below it might be headers for legacy ports such as parrallell and serial.
The other jumpers are obviously for configuration. This is marketed to industrial clients where lots of configuration options is a good thing and the people installing the boards know what they are doing.

As for the strange thing, maybe a battery holder. Hard to tell.

Phew, now stop asking so many questions and go to bed.

That's exactly what I thought after typing all that!

Thanks for the answers - they make sense...

Great pics!

I did compare the microA1-C (pix from 2soft.net) with the industrial version (your pix).
I noticed that the backplane connectors on both boards (though there are different ones) are on different positions. I always thought that the dispositions of connectors needs to be ad fixed postitions so that any miniITX case is compatible.

Or I'm seeing this wrong? Are the backplates of the cases just one big hole?

Yes. There is usually an ATX "standard" plate included with the case, but these are removable for boards that don't use a standard layout. In that case, the board maker is responsible for providing the proper backplate with thier board. Both of the uA1's will have to include a backplate, as neither one uses a typical layout.

I think that is the UBoot socket, it just doesn't have the chip installed.

I could really see one of these babies in a small DVD type case for use as a tivo like harddrive recorder, DVD copier, games console and other media storage. Include UAE and throw in a ton of games from B2TR , stick some USB ports on the front for game controllers and you have tons of fun.

Speaking of gamecontrollers, why a 15 pin gameport? Didn't that standard go the way of the dodo bird and betamax? Not to menthion that it was a really ####ty standard to begin with. I guess it must have been dirt cheap to include.

Anyway, to sum things up: GIMME GIMME GIMME

Oops! Exactly wrong. The rear connectors of both microA1s work just fine with a "standard" backplate. I'll sell yer one, if you want to check for yourself Got 'em in stock since Saturday

"C" boards available now, "I" boards available early 2005 (probably January, or February at worst).

It's for the RTC (lithium 'coin' style) battery.
