How Much was a CDC 1604 in the 60's?

An Oxymoran asks: "Greetings Slashdot. A colleague, that is sadly preparing an obituary for a late, great scientist, recently posed the following question: How much did a Control Data Corporation (CDC; Cray predecessor) 1604 cost in the late 60's? Apparently the 1604's controller computer, the 160, cost ~$100K. However, I have failed to turn up a price for the 1604. I would be highly appreciative of any estimates of 1604 prices from the 60's that the collective Slashdot genius can unearth. Thank you."

This [google.com] claims it's $10m, but it sounds a bit... boasty..

This [google.com] quotes $34,000/mo.

Maybe a post to comp.sys.cdc will get you some answers?

Do I hear 1.2 million?

[azuroff]

this list [jcmit.com] has it at $1,229,575, or $34,000/month rental.

$1.2 million.

Please learn to use Google: '"cdc 1604" cost'

that brings up another question

how powerful was it compared to today's desktops?

Re:It was $750,000

Incedentally, various inflation calculators put $750,000 1961 dollars at a little under or over $4.5MM of today's money.

CDC Cyber

Well now I feel really old. The first mainframe I ever got an account on was a descendant of the 1604, an early CDC Cyber. Our university's system operators were so proud that they'd rescued this monster CPU from a scrap heap at another university. They got it for free, it was so old and underpowered by the mid 1970s that nobody wanted it, even though it was perfectly usable and in working condition. So they fired it up and gave out free timeshare accounts to students. It made sense to them, it cost nothing to set up and very little to maintain, it ran BASIC and FORTRAN, so they let the students use it freely. In those days, a student account on our IBM 360s was hideously expensive, you got something like $50 worth of CPU cycles, when I finally was permitted to use the 360 (CS class students only) I burned through those $50 of play money in 2 weeks, I offered to pay $50 cash for more CPU time but they wouldn't do it. So I went back to the Cyber.
