       First pictures of the inside of a Mac Plus 341-0514-A BMU1 16L8 HALtaken by Travis GoodspeedThe green marks point to the chip connections that replace the programmed fuses of a PALThis may be the first time anyone has taken a picture of a HAL"HAL - Hard Array Logic The HAL family is a PAL just as a ROM is to a PROM. A standard wafer is fabricated to the 6th mask. Then a custom metal mask is used to Fabricate Aluminum links to a HAL instead of the programmable Ti-W fuse array used in a PAL."
