The Univac 3400 Computer

... never existed.

Some photographs of a Univac 9400 happened to be mislabeled, because when the computer's number appeared in them, it was fuzzy.

Another web site I turned up on Google noted that the Univac 9400 was compatible with the IBM 370.

And yet another noted that the Univac 9400 was introduced in 1968.

Those shameless imitators at IBM!

In other words, as System-370 was only introduced in 1970, the Univac 9400 could only manage to be compatible with a 360. But the erroneous website may simply have used '370' as a generic term for the whole architecture.

A German computer museum happens to have one of them as an exciting mainframe find, and it was one of the first big IBM-compatible mainframes in Thailand, apparently.

Anyways, I hadn't been able to find adequate pictures of the 494 or the 1107, 1108, or 1110 front panels... I think *finally* I will be able to add a Univac front panel to show other companies can make imposing front panels too on my still heavily IBM-dominated page. (I plan someday to add at least one more IBM front panel - that of the 7094, for comparison with the KA-10.)

Also, it wasn't until September 1971 that Univac acquired RCA's Spectra 70 business. Other sites have said that the Univac 9000 series was based on the Spectra 70. It is true that *after* the acquisition, instead of building new computers based on the 9000 series, such as by continuing with the 9700, Univac decided RCA's IBM-compatible customer base was bigger, or its operating systems more well-developed, and thus ended up asking their own users to do the limited amount of conversion required to switch from the 9400 and its relatives to the new Series 90.

Thus, I see that a *lot* of misinformation and confusion has accumulated around the earliest 360-alikes from Univac!
