Does an Upgraded Photoshop require a previous installation on a new computer?
No, but it does require having the serial number and name of the older application. When you go to activate the upgrade you need to select the name of the qualifying older product and then enter its serial number. If you did have the older version installed it would normally automatically detect it and you would not have to enter the information.
My problem is it was installed in another computer but the computer went
kaput and cannot recover. I don't have the serial number. I'm trying to buy
the original version of Photoshop 7 that I'm planning to install on my new
computer but what's available is un upgraded one.

In order to use an upgrade you need to have the older version serial number as a minimum. It is somewhat useless to purchase an older upgrade if you cannot also get the even older serial number needed to qualify it.
Indeed, this was in the EULA / Terms of Service for the old CS products:
If the Software is an upgrade or update to a previous version of Adobe software, you must possess a valid license to such previous version in order to use such upgrade or update. After you install such update or upgrade, you may continue to use any such previous version in accordance with its end-user license agreement only if (a) the upgrade or update and all previous versions are installed on the same Computer, (b) the previous versions or copies thereof are not transferred to another party or device unless all copies of the update or upgrade are also transferred to such party or device and (c) you acknowledge that any obligation Adobe may have to support the previous version(s) may end upon the availability of the upgrade or update. No other use of the previous version(s) is permitted after installation of an update or upgrade. Upgrades and updates may be licensed to you by Adobe with additional or different terms.
So you need the at least the serial number from the old version to install the upgrade... You do not have to install the earlier version(s) in order to install the upgrade.
Activation for each version is separate, and you can continue to use the old version, subject to the old license, as long as it's installed on the same computer as the upgraded version.
