OK, if you are interested, can you please PM me (it's easier for me to keep track).
Please be aware it will be a month or more before I have carts ready to ship as -
1) Need to get PCB's made (takes 2 weeks at least).
2) I have to get hold of a Vectrex.
3) 3D print the cases.
4) Build the carts.
I do however have more time to build them as my FlashBoy+ production is currently on hold.
Thanks !
