Try 4.8, it unzips for me...

UPDATE: So good news and bad news. I found another copy of 4.7.2 that unzips: https://web.archive.org/web/202103101327...7.2.tar.gz

The downside is to readme expressly states it's for Irix 6.5... So if you're trying to use it on 6.2 it's not the correct driver for you anyway.

UPDATE 2: According to Google Gemini and all other documentation I can find, the Wacom 3.2 package contains the Wacom 3.1 driver which was the driver designed to operate with Irix 6.2. Whoever they claim it was only tested on the following platforms:

IP17, IP19, IP20, IP21, IP22, IP25, IP26.
(Check the output of hinv(1) to find your CPUBOARD type:

CPUBOARD        type
IP17            Crimson
IP19            Onyx except 10000
IP20            Indigo R4k*
IP21            Power Onyx *
IP22            Indigo 2, Indy R4&R5k
IP25            Onyx 10000
IP26            Power Indigo 2
IP28            Indigo 2 10000)

I've been able to get version 3.2 working to a limited extent. I'm looking for version 4.5.1 because that is what I used to have installed on this machine under IRIX 6.2. It has a way more thorough control panel as well. 
Still having issues with 4.7.2.
When trying to extract 4.7.2 under Ubuntu 24.04, for example, I get this:
$ gunzip Wacom_SGI_4.7.2.tar.gz
gzip: Wacom_SGI_4.7.2.tar.gz: unexpected end of file
