In my story, the humans of Earth have finally made the trek to Venus, and have discovered a previously unknown life form on Venus. On closer inspection of the mucus creatures, they seem to have the Terran equivalent of a computer, and are beginning a new technological era similar to the 2000 dot-com boom on Earth.
They've detected us previously, but their top xenolinguists (and ours) don't understand anything about their communications yet. These creatures are completely without skeletal structure, but use electrically charged particles to remain upright. They are able to harden or soften "limbs", and use specially designated tentacles on their bodies, similar to a gelatinous octopus. With their limbs, they can transfer small electrical charges to any object they touch, and can control just how precise the charge is. They see via thermal sensing that provides a picture in a gelatinous "brain" (a different colored gel inside them that can also move fluidly). Atmospheric pressure, heat, acidity, and electrical discharge (for the most part) mean nothing to these individuals and cause no harm to them; Think giant sentient slimes, and you have a general idea of what they look like. Funnily enough, they breathe CO2 and excrete O3.
Given these creatures live on Venus, they are not only incredibly hot, but would have trouble using computers that are built in the same way as on Earth. To add insult to injury, the screens (visual) and most computational parts (Silicon and solder with some other metals) would either be useless or melt under the intense heat/pressure of Venus.
How can I create a "thermal" computer that my creatures can use with the same functionality of an Earth computer from the last 20th/early 21st century?
My best idea so far would be a screen that uses electricity to heat small points in a "heat screen", but given the creature's electrical charge to hold their body, I don't think the reaction would work. Similarly, I'd look at either a biological or chemical computer, but not sure how the atmosphere and heat would change the necessary composition to allow for increased processing in this.
