Amiga Oscilloscope

ScottC2010 · 20 February 2021, 15:03

Hi,
I have just got a 500+ and in the bag of bits it came in my dad had put in something of interest - a game boy oscilloscope
One can be seen here in action: [ Show youtube player ]

I was wondering if there was an oscilloscope program and hardware for the Amiga?

That's pretty cool! I've never heard of one for the Amiga, but then again I'd never heard of the Game Boy one either. There's no reason it couldn't be done in a similar way to an audio sampler, but it wouldn't be able to measure high frequencies. Doing it the way the Gameboy one works (and most decent PC-based scopes work) - having the actual scope hardware in the external device and only transferring the data needed for the display - would be a better bet without needing a faster way of connecting it to the Amiga. Software would be simple enough really, all the complexity would be in the hardware in that case.

These types of things are interesting in the "cool that they did that" perspective, but they never give the performance that you get in a standalone oscilloscope -- even a twenty year old used one off of ebay where you're paying more for the shipping than the scope itself. There is zero demand for more crappy oscilloscopes.

Trying to stay on topic, I'm unaware of any project like this for the Amiga.

Thank you - I might see if my dad would be interested in having a go as he made the one for the gameboy (It's a kit that I think came from Elektor)
He previously made us some sort of flash drive in the eighties for our Atari 600XL that you could copy games from floppy onto Eproms and then run them on it with a plug in board (Dad previously worked at Lucas where he developed brake by wire for lorries at about the same time - i remember going in one of the lorries)

I made one once for the Amiga.
I used a 6bit FLASH converter and a discrete FIFO memory. It was a very simple affair, the Amiga could trigger a capture at up to 10 Msamples/s which was the stored in the FIFO. After the capture the Amiga read out the FIFO at a slower pace.
The hardware is lost but I still have the software somewhere...

Great, thanks for these

I'm am sure I saw an advert for an oscilloscope add on in an amiga format magazine. I think it was made by datel? acquisition unit or something?

Oh, and that is a really cool gameboy you have!

Thanks, these look good too - i'm going to get my dad to make the cable for the one i found and then i will have a look and see if i can find the software for these too
