Jonathan (Glitch) has sells similar dallas products on tinder. I was hoping he had that one too but its not there https://www.tindie.com/stores/glitchwrks/ He'd know best if this or necroware would work. I think there's tricky issues- what the clock features are, what the computer uses of it that substitutes may or may not work. On 8/26/2022 7:28 AM, Martin Flynn via vcf-midatlantic wrote:
CDL has a piece of telecom hardware that has a failed clock chip (same part as may early computers)
Failed chip is a DS14287. It's suggested replacement is a BQ4287MT-SB2. Both are NLA
Rather than grind the chip open and piggyback a battery on it, has anyone built one of these https://github.com/necroware/nwX287 as a replacement? https://www.youtube.com/watch?v=svPNxILeQEw
