Re: Simultaneous internet & mass storage solutions for the A3010

the nodemcu esp8266 lolin board coupled with one of those little max232 boards to do the level shifting comes in at under a tenner. There's gpl'd firmware out for it Now that sounds like a nice idea :D - especially as the WiFi232 things appear to be not generally available... This makes me wonder h...

Re: Archimedes Iomega ZIP drivers

Just follow the step by step instructions here: http://www.snowstone.org.uk/riscos/documents/newold.html FTPc isn’t part of uniboot, but uniboot contains everything you...
