Tandon PCA
RH-4UJN
Tandon's AT-class 286, from the drive maker that supplied half the industry. This one was found in extremely poor condition, having been home to rodents: every surface is contaminated, corroded and filthy, and the machine is a candidate for parts or a long decontamination rather than a switch-on.
