Abstract : A 15-bit base register and a 9-bit complementary register are added as additional means of addressing to the M-220 computer. The address register is enlarged. These means provide a straightforward addressing within a 32 K core memory i.e. allow to make a continuous indexing of 32 K arrays and to transmit by a single pseudo-instruction information files of up to 32 K words between internal and external memory units. The paper describes both mathematical and electronical modifications of the computer. (Author)
