Checked with a voltmeter with the power on. A steady 4.96 to 4.97 volts. Bam.

This means it's probably a 6v unit. I'll probably go with a 10v to be safe? I mean the thing was in pieces, the display was connected and on, trackball, a SCSI HDD, UltraDock, external FDD, no modem card, and a paltry 4MB RAM card.

From the very limited accurate information online, "5B7" refers to a case size. Which is about right since it's about 6mm x 7mm...ish. The actual voltage rating can be 4V to up to 63V. source

Since it says "33 EHA 5B7", 33 probably refers to ...I dunno, there's a possible match at 10v 33uF with a 5B7 case size. I don't care about the case size because of what I'm replacing all my caps with (electrolytic), I care about the capacity and voltage.
