Brother 970 Electronic
This, the last and most expensive model sold by Brother has an onboard computer and you can design from screen your garments using a selection of symbols however the screen is way too small for my liking so I will continue to use Designaknit. Unlike the Brother 940 this machine requires a magnet to actually knit from the Designaknit screen.
The Brother 970 comes with a special addition of a bracket that attaches to the rear of the garter carriage, the good news is that you no longer require the garter carriage to travel to the end of the machine before it turns.
To my mind a very lucky find for me - I love any machine that has computer possibilities as all that mylar sheet and punchcard business is not for this lazy so and so.
