SAPO (computer)

The SAPO (short for Samočinný počítač, “automatic computer”) was the first Czechoslovak computer. It operated in the years 1957–1960 in Výzkumný ústav matematických strojů, part of the Czechoslovak Academy of Sciences. The computer was the first fault-tolerant computer – it had three parallel arithmetic logic units, which decided on the correct result by voting, an example of triple modular redundancy (if all three results were different, the operation was repeated).

SAPO was designed between 1950 and 1956 by a team led by Czechoslovak cybernetics pioneer Antonín Svoboda. Svoboda had experience from building in the United States, where he worked at MIT until 1946. It was an electromechanical design with 7,000 relays and 400 vacuum tubes, and a magnetic drum memory with capacity of 1024 32-bit words. Each instruction had 5 operands (addresses) – 2 for arithmetic operands, one for result and addresses of next instruction in case of positive and negative result. It operated on binary floating point numbers.

In 1960, after a spark from one of the relays ignited the greasing oil and the whole relay unit burnt down, it was decided not to repair the computer because of its obsolescence.

Usage examples of "sapo".

A big-bellied man called El Sapo had taken control of the landing party, setting up a tent and preparing for the night.

The cook gave him a ladle of yellow synthetic mush from the supper kettle and El Sapo tossed him a blanket, but nobody talked to him.

El Sapo had left him out of the gang of axemen sent upriver to begin cutting timber for their first building, but he was allowed to ride the floating logs down the stream and roll them back into the channel when they ran aground.

El Sapo was careful to see that they got a fair share of the limited food and gear, but his mistrust had been contagious.

As happy as she was, El Sapo detailed men to move them there, with a tiny tent, a few simple tools, and their fair share of the rationed food.

El Sapo and his followers still near the pad, locked in a hostile confrontation with El Jefe, the new leader of the premen.

The men were long-bearded and the women bedraggled, all of them pinched from starvation, but El Sapo was trying to assert his old authority.

Now, squeaky-voiced with alarm, he was demanding information about where El Sapo had been.

El Sapo kept insisting that he had been risking himself and his friends for the benefit of all, with no intention of deserting.

El Sapo and Jesus Cabrito were probably still squabbling for domination, but neither would love the unborn ultiman.

In the face of a mounting body of evidence Holmer, discredited, was replaced by an attorney-general who refused, consistently, to give hearing to any statement that threatened to contradict the official line: all enquiry would be secret, and conducted by the secret police, the Sapo known for detestation of all that Palme stood for.

But it would be infinitely easier to check with every one of them than to have to bed that criadero de sapos of a comandante.
