The TRS-80 Micro Computer System (TRS-80, later renamed the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. It is one of the earliest mass-produced and mass-marketed retail home computers.The TRS-80 has a full-stroke QWERTY keyboard, the Zilog Z80 processor, 4 KB DRAM standard memory, small size and desk footprint, floating-point Level I BASIC language interpreter in ROM, 64-character per line video monitor, and a starting price of US$600 (equivalent to US$2,600 in 2021). A cassette tape drive for program storage was included in the original package.
While the software environment was stable, the cassette load/save process combined with keyboard bounce issues and a troublesome expansion interface contributed to the Model I's reputation as not well-suited to serious use. It lacked support for lowercase characters, which also hampered business adoption.
An extensive line of upgrades and add-on hardware peripherals for the TRS-80 was developed and marketed by Tandy/Radio Shack. The basic system can be expanded with up to 48 KB of RAM (in 16 KB increments), and up to four floppy disk drives and/or hard disk drives. Tandy/Radio Shack provided full-service support including upgrade, repair, and training services in their thousands of stores worldwide.
By 1979, the TRS-80 had the largest selection of software in the microcomputer market. Until 1982, the TRS-80 was the best-selling PC line, outselling the Apple II series by a factor of five according to one analysis.In mid-1980, the broadly compatible TRS-80 Model III was released. The Model I was discontinued shortly thereafter, primarily due to stricter FCC regulations on radio-frequency interference to nearby electronic devices. In April 1983, the Model III was succeeded by the compatible TRS-80 Model 4.
Following the original Model I and its compatible descendants, the TRS-80 name became a generic brand used on other unrelated computer lines sold by Tandy, including the TRS-80 Model II, TRS-80 Model 2000, TRS-80 Model 100, TRS-80 Color Computer, and TRS-80 Pocket Computer.

This is my second 80% I've done, the first one went very smoothly. This one has been a different experience.
I didn't notice those cuts on top until sometime during the second stage of routing.

Is this still usable or is it a paperweight?
I have several new 80% raw billet mil-spec 7075-T6 aerospace grade aluminum AR-15 lowers from Tactical Machining for sale.
$100 each or $500 for all five + new Anderson jig.
Alternately, I'm open to trading for a CZ-75, Tanfoglio, or similar metal-framed DA/SA pistol.
For the right trade...
We finally machined the 80% AR10. Turns out the fire/safety detent hole is drilled at an angle preventing the fire/safe selector switch from operating correctly. We drilled the selector switch hole in the jig (EasyJIg Gen2) and it's perfect.
The fire/safe detent hole from the mfg is drilled at...
