Vintage DB25 3 Port Manual A/B Data Switch Box Parallel Serial Non-Tested

PRODUCT OVERVIEW
Up for sale is a vintage 4-Port Manual Data Switch Box featuring a classic cream-colored heavy metal chassis enclosure. This legacy mechanical matrix router allows a user to manually toggle a single input/output line across four distinct target hardware pathways (labeled A, B, C, and D) via a heavy-duty rotary dial selection switch on the front faceplate. The back panel features five female 25-pin DB25 interface connection layout ports (4 channel lines plus 1 main master connector input-output).This passive hardware configuration is highly prized by retro computing collectors, vintage industrial hardware restorers, CNC machinery technicians, or classic lab technicians managing legacy dot-matrix printers, early external modems, or vintage computing terminals.CONDITION
Estate find / Untested. The structural metal enclosure is in excellent vintage cosmetic condition. The mechanical rotary front dial clicks firmly into position across each mapped channel index (A, B, C, D) without slipping. The interior pins on the blue DB25 connection matrix are straight and clean, showing no terminal decay. The bottom plate retains its vintage \"Made in Taiwan R.O.C.\" oval foil sticker.Please note: The bottom plate is missing one of its four black rubber feet (as shown in the bottom-view photo), causing it to sit slightly unevenly on flat surfaces. Because it requires active vintage serial/parallel component networks to verify data link continuity, it has not been signal tested and is sold strictly as-is / for parts or repair.WHAT IS INCLUDED
