Hello, I'm just looking for prices on both of these, what they might sell for.

Digital Press gives a $40 value to Jawbreaker. Don't know about the Invitation to Programming tape but I'd guess not much as it's fairly common and nobody really cares about non-games on tape. I'd be interested in Jawbreaker if you decide to sell it.

Thanks for the info and the offer. Sorry for the late reply, been busy with irl stuff. The cartridge is sold.
