This system has the well-respected LNW Research System Expansion board with the optional LNDoubler double-density disk drive adapter. The base unit is a Model 1 Level 2 with 16K of RAM. The LNW System Expansion has an additional 32K of RAM, floppy drive interface, parallel printer port, RS-232 serial port, dual-cassette interface, and a sound board and speaker.
The floppy disk drives include a single-sided, double density boot drive plus two dual-sided, double density drives. A spare single-sided drive (for parts) is included).
The system quickly boots up, loads and runs programs, and functions quite well. I put this system together about 45 years ago to use for both business and personal purposes. I have labeled the connectors and cables to assist in making proper hookups. Note that due to the age and nature of these devices, I cannot offer a guarantee of continued functionality, but the TRS 80 Model 1 still has a thriving community of dedicated users who are happy to offer very helpful advice. The 5.25” floppy disk drives can be a little temperamental at times, but with over 50 floppies included, you'll have plenty of additional options. I'm including a signal conditioner which can help with reading cassette tapes (the TRS 80 was always a little picky about volume settings) but most of the cassette programs were transferred to floppy disks so you probably won't have to fiddle with cassettes too much anyway.
Both the TRSDOS and DOS Plus operating systems are included. Although DOS Plus has more capabilities, some software will only work on TRSDOS. With this system you can run either one just by booting from the correct floppy disk.
Please remember that this system is 45 years old. Unlike today’s PCs, the TRS-80 is not a plug-and-play computer. That's one of the reasons I've carefully labeled every cable and connector. It also is not compatible with modern PC software. I've included floppy disks which include many TRS 80 games and applications such as Scripsit (word processor) and the first spreadsheet program—VisiCalc, so that you'll have a lot of fun using this system.
You must agree that you are buying this system with the understanding that some parts may fail due to age and not everything can be expected to work properly. Tinkering is part of the fun of owning an old computer system and the huge quantity of included documentation should help you to resolve most issues you may encounter.

I will only accept cash. No checks, credit cards, trades, or other forms of payment. I will not ship this system--you must pick it up in person in the VC Highlands a short distance off Geiger Grade (Hwy 341) between Reno and Virginia City only. Everything is in four large boxes weighing over 120 pounds in total, so you'll need a vehicle which can accommodate the volume.
Please respond via email or by calling. I won't receive texts. I also won't respond to messages asking me to enter a code somewhere. I will only deal in person.
