I have an 8K cartridge, and I believe also a 16K cartridge gathering dust on my shelves. Email me your address, and I'll ship them off to you ... No guarantees that they work, but they're free :-) Also, try www.cmdweb.com. Prices are high, but they do have a lot of otherwise unavailable stuff for VICs, C-64s, and C-128s. Just judging on price alone, I'd say yes, but as other have suggested, only you can decide that.... I have paid probably more than others would pay for a lot of things in my life, but at the time I considered them good deals...
