This is the recovered Machine Room from 2005. Please don't expect wonders. The look and feel of this site is nine years
old, and so is its code. Some of the functionality has been recovered while the rest of
the site is modernised and restructured. Watch this space!
The UNIVAC II was a mainframe computer with 72 bits per word. It used excess-3 binary coded decimal arithmetic with 6 bits per digit, allowing 11 digit signed numbers. Instructions were 36 bits long, packed 2 per word.
Core memory of 2000 words (expandable to a maximum of 10000 words). Although it is not entirely a fair comparison, because this was a word oriented decimal machine, this is about 17.6 KiB . The core memory had one parity bit on each digit, for error checking, resulting in 84 bits per memory word.
