I was a bit incorrect. The 26-1138 is just the WD controller for the Model 4 that allowed it to use the 25-1041 as its primary drive. I should have remembered as I have one somewhere. The 25-1041 could be used by any MFM controller including the 26-1138 or the Tandy 1000 controllers.
The other one is a 26-1138 primary drive intended for the Model 4. It has the 50 pin connector on the back and a full WD1010 controller board. The 25-1041 is a dumb secondary in this configuration.
You guys are too funny. I only have half of the 1984 production run. :)
The answer is 95%+ of them have been scrapped. They are too big to just chuck in the closet.
I'm starting to collect Tandy PCs from 1000 to 5000 and am interested in extremely nice original examples for my collection. If you have one for sale or maybe trade for a Model I/II/III/4 please get in touch.
If you're joining us for tonight's show please take a look at the August 1982 issue of 80micro magazine. We're going to walk through the issue together and have some fun. You can get a copy at...
