"Nintendo, for example, showed the Kittyhawk team an entertainment system they had already designed, unbeknownst to HP, with a slot for a Kittyhawk drive to be plugged in—a module that could contain many more games, with much more sophisticated graphics, than Nintendo’s conventional cartridge approach. ‘The system is all set,’ the Nintendo representative persuaded. ‘All you have to do is sell us your drive for $50.’ When White protested that the Kittyhawk’s accelerometer alone (required for shock resistance) rendered the $50 price impossible, Nintendo responded that they did not need the accelerometer— they just needed 20 megabytes at $50, cheap and simple."

In reference to the HP Kittyhawk hard drive
. This hard drive was introduced in 1992, plausible that this is what was intended for the Satellaview.
For some context, the quote is from a case study on the HP Kittyhawk hard drive project from a business standpoint. The study did mention that Nintendo was a potential customer and showed interest in the hard drive after the idea of a miniature mass storage device was pitched to Nintendo marketing manager at a trade show. What 'system' the quote mentions can be up for interpretation but I am placing bets on the Satellaview.
