Hello my patrons! Next up we have what was supposed to be a quick video on my 5170. I had wanted to fix the constantly dying NVRAM/CLOCK battery on this machine so I had an idea on how to fix that. In the process, I was going to swap the motherboard to a 10mhz (overclocked) 5170 motherboard I had prepared in a previous video. 

Well, everything went horribly wrong and the upgrade ended up taking way longer than I had anticipated as I ran into numerous roadblocks and issues.

This easy IBM 5170 upgrade video turned into a disaster

This video was supposed to just be a quick video of me swapping the motherboard on my 5170 and replacing the VGA monitor. It turned out that, as per the usual situation with this machine, I ran into a ton of issues and this work took me so much longer to do than anticipated. -- Video Links IBM PC 5170 Series: Part 1: https://www.youtube.com/watch?v=hKgIdBIeCN0 Part 2: https://www.youtube.com/watch?v=QFpJ3uWIqVQ Part 3: https://www.youtube.com/watch?v=bxnJhUyhszk Fixing and improving the IBM PC/AT 5170 BIOS: https://www.youtube.com/watch?v=qO3xrl0XR-4 IBM PC 5170 Overclocking: https://www.youtube.com/watch?v=81ezGc1Eb1M Improving the BBC Master: https://www.youtube.com/watch?v=2Sgleturods Adrian's Digital Basement Merch store: https://my-store-c82bd2-2.creator-spring.com/ Support the channel on Patreon: https://www.patreon.com/adriansdigitalbasement Adrian's Digital Basement (Main Channel) https://www.youtube.com/channel/UCE5dIscvDxrb7CD5uiJJOiw -- Tools Deoxit D5: https://amzn.to/2VvOKy1 http://store.caig.com/s.nl/it.A/id.1602/.f O-Ring Pick Set: (I use these to lift chips off boards) https://amzn.to/3a9x54J Elenco Electronics LP-560 Logic Probe: https://amzn.to/2VrT5lW Hakko FR301 Desoldering Iron: https://amzn.to/2ye6xC0 Rigol DS1054Z Four Channel Oscilloscope: https://www.rigolna.com/products/digital-oscilloscopes/1000z/ Head Worn Magnifying Goggles / Dual Lens Flip-In Head Magnifier: https://amzn.to/3adRbuy TL866II Plus Chip Tester and EPROM programmer: (The MiniPro) https://amzn.to/2wG4tlP https://www.aliexpress.com/item/33000308958.html TS100 Soldering Iron: https://amzn.to/2K36dJ5 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://amzn.to/2RDSDQw https://www.ebay.com/itm/USB-Logic-DSLogic-Basic-Analyzer-16Ch-100MHz-4Ch-400MHz-Xilinx-Spartan-6-FPGA/202543965672 Magnetic Screw Holder: https://amzn.to/3b8LOhG https://www.harborfreight.com/4-inch-magnetic-parts-tray-90566.html Universal ZIP sockets: (clones, used on my ZIF-64 test machine) https://www.ebay.com/itm/14-16-18-20-24-28-32-40-pin-IC-Test-Universal-ZIF-Socket-Fs/303206721971 RetroTink 2X Upconverter: (to hook up something like a C64 to HDMI) http://www.retrotink.com/ Plato (Clone) Side Cutters: (order five) https://www.ebay.com/itm/1-2-5-10PCS-Micro-Scissor-125mm-PLATO-170-Electronics-Cutter-Side-Cutting-Pliers/163458746184 Heat Sinks: https://www.aliexpress.com/item/32537183709.html Little squeezy bottles: (available elsewhere too) https://amzn.to/3b8LOOI --- Links My GitHub repository: https://github.com/misterblack1?tab=repositories Commodore Computer Club / Vancouver, WA – Portland, OR – PDX Commodore Users Group https://www.commodorecomputerclub.com/ --- Instructional videos My video on damage-free chip removal: https://www.youtube.com/watch?v=XQVjwPsVFd8 --- Music Intro music and other tracks by: Nathan Divino @itsnathandivino

On the Necroware you pulled pin-1 up to 5V to tell it to go into Motorola mode. You checked the schematics and pin-1 isn't used; however, what if pin-1 is connected to something on the motherboard.

Watching the video and I had to grab my phone to leave this comment. Here’s my stupid IBM 5170 question of the day: Are those factory hodge wires on the bottom of the board or are those there due to a previous owner’s reword? It didn’t seem like they were part of the overclocking. Thanks for sharing. I’m (re)learning a lot of early IBM hardware from these videos.
