I've had these .bin images for a while but no programmer for them. I figured I'd share them here. The EGRETs you see here are 341S0850, 341S0851, and 344S0100.
Yeah I think you'd need an old special programmer and chips or an adapter. I know these were around a while back but I haven't been able to find them on a search so just figured upload them here for safe keeping.
reverse engineer the original firmware to determine its functionality, recreate a new program in C and compile it to an AVR or PIC, using an adapter board. If you wanna get fancy, then ASM. haha.
Traded it with someone from Australia supposedly OzTechnics was a short lived company but somehow the software was preserved on the way back machine. Might I be able to use this to dissect the EGRET?
If anyone has a Windows 98 Laptop I'd be willing to ship this out for them to try and see if it can read an EGRET/CUDA, there's a ton of brand new adapter boards that came with it.
