SHIFT838 Unicorn

Introducing the 838 Unicorn PCB, a must-have accessory for the 99/22.  This is the GROM simulator PCB that has been redesigned to a smaller footprint and allows the board to be directly plugged into the Unicorn port (header J4) vertically.  This new design allows for the 838-Unicorn board to sit directly over the 99/22 mainboard.  This board gives no added functionality from the original, it is just a design change.

This is only the blank PCB; options can be added when adding to cart.

Please be aware if choosing to assemble you will need the board programmed with one of the GROM loads offered.  If anything, other than Standard TI GROMs is programmed to the Unicorn then the 99/22 will require the additional EPROM that can be added to the package, or you can program one yourself. 

If you want to run extended basic from the onboard cartridge EPROM then the GROMS required with be the Extended Basic version you want.  The EPROM must match the GROMs loaded, or it will not work.

Please select appropriately.
