The transistors are available at DigiKey as well.I had seen your parts list after I had sourced my parts.I modified it for this build.I also had removed the heat shrink because I had it on hand and it’s also often readily available locally.http://www.digikey.com/short/j20td4 This list brings the DigiKey parts cost to under ten bucks.

What we've needed for a long time. I had put together a pre-loaded digikey cart to build a marty goodman cable, but this will be better. I found "dupont" style connectors with crimp on pins, and a polarity key that fits in the drive. I never found the metal encased plug like the original, but that one isn't keyed anyway, the key is formed in the outer vinyl molding. http://tandy.wiki/TPDD#Parts On Sat, Sep 8, 2018, 6:56 PM CHARLES SHEAR<[email protected](mailto:[email protected])>wrote: > > Whoops, LOL.https://rsmicro.wordpress.com/ > > > On September 8, 2018 at 5:06 PM Brian > > White<[email protected](mailto:[email protected])>wrote: > > > > I'm definitely interested. > > > > On Sat, Sep 8, 2018 at 3:27 PM CHARLES > > SHEAR<[email protected](mailto:[email protected])>wrote: > > > > > > Based on the information I read in Marty Goodman's write up on his cable > > > disassembly and reverse engineering, I have come up with a variation of > > > his design that definitely is working with my 100, 102, and TPDD.I don't > > > know if it's been discussed since Marty did his work back in '89, but > > > based on his description, I may have found his "tiny rectangular > > > components"with the "designation "14" on them". > > > > > > > > > > > > > > > > > > > > > I don't know if photo's are allowed in this mail list, so I'll just post > > > a link to a blog I setup real quick to explain my thoughts and show the > > > cable design I came up with. > > > > > > > > > > > > > > > > > > > > > Let me know what you think, > > > > > > > > > > > > > > > > > > > > > Rick > > > > > > > > > > > > > > > > -- > > bkw
