8K Basic ROM

While the 4K Integer Basic in the Sinclair ZX80 is adequate for many applications, most programmers will eventually feel a hunger for more power. True, advanced functions can be simulated by way of subroutines, but such measures eat memory at an alarming rate. Enter the 8K Basic ROM. The chip costs a mere $39.95, which is an extremely low price for any ROM. Some versions of Basic are sold for over $200 on disk. Sinclair gets four stars for not robbing its customers.
