After the successful Kickstarter, a number of changes were required in order to satisfy the new stretch goals. Twin joystick ports presented a problem in terms of available space on the board and the case. A few alternatives were discussed.
Finally the idea of having both ports on the front was settled on.
The Raspberry Pi Zero was relocated to the back of the machine.
A decision was made at this point to produce a single board which would work for both board only and cased pledges. This required that the daughterboard was physically attached to the main board.
Due to height restrictions on a standard ZX Spectrum 48 case, the preferred joystick ports could not be used and so four joystick port positions were created. Two on the right for the standard ZX Spectrum case and two on the left using more robust ports for the ZX Spectrum Next case. The following was used originally to describe the concept.
The Issue 2 board design was completed on the 28th June 2017.
