The machine came with 512k of on-board RAM. it was all discrete memory
chips . I'd have to look at it...but they were probably 10k or 20 k each

The computer I had that had 512KB on-board had 2 banks of 256Kb * 1
chips (18 RAM chips total, since 1 chip per bank was for parity).

Note the difference between bytes (B) and bits (b).
