Part 1: I love 70s and 80s computers! I was lucky to have found this Radio Shack Tandy TRS-80 Model 4 in the original box! In this video, I unbox it, take a close look at it and then boot it up. Watch to see what happens... --- Video Links Part 2: https://youtu.be/s8jVgUt7elU --- Information Thanks to viewer Richard Lorbieski who provided this additional information: [[The store that that computer was shipped to was most likely a Radio Shack franchise dealer. Every Radio Shack/Tandy in the 70-80s had a store number - including the regional distribution warehouses and computer plants. Radio Shack #0603 appears to be a regional distribution center. I started as a Tandy employee at Tandy Computer Assembly (TCA) in San Antonio, Texas from 1981-1982. Our store number was #0067. We assembled Model IIs (mainly international version), Model III 4K and 16K versions, Modem 1 and 2s, Power Plug and play. I transferred out the Radio Shack Retail Computer Repair, TCA was ramping up Model 4 production. The plant was closed in late 1985. The "N Proud" were QC stamps. They used those stamps after I left. There were 4 major assembly and testing areas at TCA - Base, Video, Board Prep, and Burn In. Each assembled unit was burned in for at least 24 hours. The Board Prep area burned in mother boards for at least 4-12 hours. I worked in the tech area that repaired the motherboards and drives. I mainly worked on Model II boards and the 8 inch Shugart disk drives. The 5.25 drives are single sided made by Texas Peripherals (TPI), that company was a joint venture of Tandy and Data Point (based in San Antonio). The plant was located in Odessa , Texas. The power supply was also a Tandy made product.]] --- Tools Deoxit D5: http://store.caig.com/s.nl/it.A/id.1602/.f Jonard Tools EX-2 Chip Extractor: https://www.jonard.com/Products/EX-2-DIP-IC-Extractor-24-40-Pins Wiha Chip Lifter: https://www.wihatools.com/precision-chip-lifter Elenco Electronics LP-560 Logic Probe: https://www.amazon.com/Elenco-Electronics-LP-560-Logic-Probe/dp/B000Z9HAP4 Hakko FR301 Desoldering Iron: https://www.amazon.com/American-HAKKO-Products-FR301-03-Desoldering/dp/B07BFVFMS9 Rigol DS1054Z Four Channel Oscilloscope: https://www.rigolna.com/products/digital-oscilloscopes/1000z/ Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier: https://www.amazon.com/SE-Illuminated-Dual-Flip-Magnifier/dp/B003UCODIA TL866II Plus Chip Tester and EPROM programmer: (The MiniPro) https://www.aliexpress.com/item/33000308958.html TS100 Soldering Iron: https://www.ebay.com/itm/TS100-65W-MINI-Digital-OLED-Programmable-Soldering-Iron-Anti-static-Structure/113382669853 EEVBlog 121GW Multimeter: https://www.eevblog.com/product/121gw/ DSLogic Basic Logic Analyzer: https://www.ebay.com/itm/USB-Logic-D ... https://www.youtube.com/watch?v=5NJDkQtCZ3k
