24-bit, five-digit decimal Memory Address (no 8 - Ten Thousand bit stored) 1 plane 384 cores; The address decoding logic of the Main memory also used two planes of 100 pulse transformer cores per module to generate the X-Y Line half-current pulses. There were two models of the 1620, each having totally different hardware implementations: IBM 1620 I
Some older computers (decimal computers), were decimal digit-addressable. For example, each address in the IBM 1620's magnetic-core memory identified a single six bit binary-coded decimal digit, consisting of a parity bit, flag bit and four numerical bits. The 1620 used 5-digit decimal addresses, so in theory the highest possible address was ...
An early widespread implementation was available via the IBM 1620 of 1959–1970. The 1620 was a decimal-digit machine which used discrete transistors, yet it had hardware (that used lookup tables) to perform integer arithmetic on digit strings of a length that could be from two to whatever memory was available. For floating-point arithmetic ...
Make an ordered list. The default is a numbered list, but you can change it to a list with roman numbers or letters of the English, Greek, Armenian or Georgian alphabets, instead of the decimal enumerator. Template parameters [Edit template data] This template prefers block formatting of parameters. Parameter Description Type Status First item to list 1 no description Unknown required Second ...
Four-digit address; Registers. All registers use one word and can also be addressed as memory. Accumulators – three (addresses 9991, 9992, and 9993 – standard; 99991, 99992, and 99993 – extended 7074) Program register – one (address 9995 – standard; 99995 – extended 7074) Addressable from console only. Stores current instruction.

IBM 650 front panel with bi-quinary coded decimal displays. A decimal computer is a computer that represents and operates on numbers and addresses in decimal format – instead of binary as is common in most modern computers. Some decimal computers had a variable word length, which enabled operations on relatively large numbers.
