Re: AcornA7000 Motherboard alive and well need some basic help now... (if I may)

So I was able to get the A7000 to see the gotek and the utiles.adf disk image. I was able to format the CF card as a 250 meg drive. I selected make it bootable, but it won’t boot from it. !boot is missing or something. :0) I take it, make it bootable still requires you install some kind of OS on it....

Re: Acorn A7000 Motherboard alive and well need some basic help now... (if I may)

Very helpful Icww1, thank you. I did not know that.

The link I provided above only seems to have games, can anyone provide a link to, or an actual disk image i can use to setup my hard drive, this elusive !HForm and any other utils to get me started?

Cheers.

Re: New Atom owner (soon)

Thank you, yes, that's the schematic I will most likely use when I swing around into Acorn Atom mode, currently messing around with a ESP32 based wifi modem for my Commodore 64 and 128. :) it's nice logging into BBS's at 2400 board.

Very nifty indeed. :)

Pictures comparing the colour output of the colour board to the monochrome output of the atom on pin 9-10 of video connector. I thought the colour output would be grey scale on a B&W tv, but it appears to be “dotted” like with the Apple II (artifact colour) At any rate here are images from my little...

As stated previously as a kid I never hooked up my Acorn Atom to a colour TV, as a result I’m not sure what looks right. I find in text mode the characters appear as a light green on a much darker green. Is this normal? Also I wonder about some of the text graphics with very black spaces. (Not the s...

Re: My New Acorn Atom :)

I just plugged my ATOM in without an SD card, and yup after about 18 seconds, i get the Banner, so my previous post was incorrect. Without an SD card, I do get the Acorn Atom + AtomMMC banner, after the usual 18 second delay on a very cold boot. I will try an other sd card, and see if that changes.....

Re: My New Acorn Atom :)

Pretty sure Ive checked it without an SD card, and it will not post Acorn Atom + Atommc2.
I will have to try again, to be certain. (memory fading and all...) :) I'm using the A000 version of the rom. :)

I will test tonight, when I get home from work. And test with another SD card as well.

Re: My New Acorn Atom :)

they do their initial blinking on power up.
Pretty sure that is the only time they blink unless there is disk access.
pretty sure it does not blink at the 12 second mark when the heading on the tv changes from Acorn Atom to Acorn Atom + ATOMMC2

I will do more testing. :)

I will have to check. It did this with two separate power supplies. Both at least 2.amp. Both are from name brand devices. The output with no load was about 5.25.
