Easy assemble 16K ram pack kit for a Sinclair ZX81. Solder the 3 components in the right place and you are good to go. The edge connector is on one side and Chips on the other side.  The kit comes with PCB, 2 chips, 2 chip sockets, 1 edge connector and 1 spacer to put under the edge connector while you solder it in place to give you a bit more clearance. 



Delivery policy


Return policy

Comes as a bare PCB (no case). I have provided drill holes so you can design your own case. No returns if the Kit solder work has started. 

I've started testing all memory chips before they leave the door - Memory tester is not included in the sale. 

The 62256 chip could be refurbished but is still 100% operational and had no complaints.
