Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 290MHz)

Thanks guys, Dave's suggestion worked perfectly (kicking myself for not trying it first! doh!). A couple of CTRL Breaks and all is good with the Pi4. My Pi 3 that I thought was dead, turns out it was a bad SD card and it works again (Lazarus style! Wife is super impressed... ). It steadfastly refuse...

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 290MHz)

Pi 4 arrived today, works fine (testing running various pi4 builds of stuff) but the Beep refuses to recognise it via the CoPro interface. I'm using a fresh sd card with Fer-De-Lance on it. I've tried the same SD card & same software in the zero and it works fine. I'm connecting the cable with the s...

You can tell her you will need a spare Pi4 as well, just in case. And it will reduce the unit postage cost, hopefully go down well with Mrs Muddy.

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 274MHz)

Cable works perfectly - Thanks Beebmaster. Unfortunately my Pi3 is dead. I hooked up the zero first of all, using the cable, turns out I didn't have the cable on 100% correctly and had missed the final row of pins. Once corrected, the Pi Zero fired up first time as normal. All good. (probably lucky ...

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 274MHz)

I was thinking more of keeping the pi outside the case and having a longer cable, maybe routed out via the cart slot that I don't use (I have the Nula rom sitting in the other).

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 274MHz)

Hi all,

I currently have a PiZero connected internally on my master but I want to connect up my pi3b. What ribbon cable would I need?

Is it just a regular 40 Pin GPIO Ribbon Cable ? (https://thepihut.com/products/40-pin-gp ... -gertboard)

Appreciate any guidance :)

If i was going to get a run of say 10 of these boards made, what file would I send the manufacturer? the board file or the schematic or both ? do I need to convert them to a "gerber" file?

ANy suggestions would be appreciated so I don't go and order the wrong thing :)
