Hi, Thanks for this info! Good to know it. I will check those craignell ones!

I was trying to replace a 6530 for KIM1 (project abandoned all my time lost) you can also try: https://www.enterpoint.co.uk/products/obsolete-component-replacement/craignell-1/ or https://www.enterpoint.co.uk/products/obsolete-component-replacement/craignell-2/ but beware for the craignell the GND and VCC pin are not remappable you have to specify the position when you order. I'm often using a craignell-1 28 pin as eprom when I'm developping (quickly reprogrammed via jtag, without the need to remove the chip / erase / reprogram/ reinstall) I had several problems.... - problems with the level shifters - problems of delay - problems with glitches to filter On 16/07/23 11:27 PM, Hegedűs István wrote: > Hi, > > I believe that should be much easier.
