I found this one on Facebook Marketplace. It wasn't in bad condition and came with the original Compaq power supply. It has a 486DX/4-100 and has 16MB of RAM (8MB onboard + 8MB expansion) and a 720MB IBM hard drive. I've cleaned it up a bit and repaired some damaged plastics but overall it's in pretty good condition. The screen is a fair bit larger than the one in the 410C but the backlighting isn't as even, though this is only really noticeable on dark backgrounds.
