I'm new to electronics and currently watching through a series on youtube about how to make an 8-bit computer out of breadboards. In his video about the RAM module, he uses 2 74LS189 chips. I've had a look around but none of the websites that offer free shipping to Ireland stock them. So if anyone knows of a similar chip that would accomplish the same task it would be great, I'd rather not spend an extra €15 on postage for 2 chips.
