\'There are indeed plans to create a SCPU image for the 1541U Hardware. That means: no hardware change, but a completely different behaviour of the cartridge. The FPGA content would be different of course, offering you SCPU functionality. So *NO* built-in 1541, but just SCPU. [Of course the idea is that two 1541U`s should work in a cart-expander, one as SCPU, one as 1541U.]\'
