Offered here is an originalRadio Shack TRS-80 MC-10 Micro Color Computer, Model 26-3011, introduced in 1983 as Tandy/Radio Shack's compact entry-level home computer.
This MC-10 has beentested and working, opened for internal inspection, carefully cleaned and successfully retested after reassembly.
The listing includes theMC-10 computer, power supply and serial cable.
TESTING PERFORMED
The computer was connected to an external display and tested for operation.
Testing included:
- Powers on normally
- Boots successfully toMicro Color BASIC 1.0
- Keyboard tested
- BASIC commands entered successfully
- BASIC program entered and executed
- Available memory checked from BASIC
- Color output tested
- Sound output tested

The computer reports approximately3,135 bytes available to BASICafter startup, consistent with its original 4 KB RAM configuration.
This machine istested and working, not being sold as untested or merely "powers on."
CLEANING & INTERNAL INSPECTION
The MC-10 was carefully opened for cleaning and visual inspection.
The interior and motherboard were inspected for obvious damage, corrosion or other problems.
Cleaning included:
- Exterior case cleaning
- Keyboard cleaning
- Interior dust removal
- Connector cleaning
- Connector inspection
- General visual inspection of the motherboard
- Cleaning of accessible internal areas
The MC-10 has a large factory RF shield covering a substantial portion of the motherboard. The shield issoldered to the board from the factory.
Because this computer is functioning properly, the factory shield was intentionallyleft intact rather than unnecessarily desoldered from a working vintage motherboard.
No unnecessary modifications were performed.

ABOUT THE TRS-80 MC-10
Introduced in1983, the MC-10 — orMicro Color Computer— was Radio Shack's compact, low-cost entry into the early home-computer market.
Although related to the Tandy Color Computer family, the MC-10 uses a different processor architecture and was designed as a much simpler entry-level system.
Key specifications include:
- Motorola MC6803 processor
- Approximately0.89 MHz
- 4 KB RAM
- 8 KB Micro Color BASIC ROM
- Motorola MC6847 video display hardware
- Color graphics
- Built-in sound
- RF television output
- Cassette storage interface
- RS-232 serial interface
- Keyboard with BASIC command shortcuts
The MC-10 was a relatively short-lived member of the TRS-80/Tandy computer family and today is an interesting collectible example of Radio Shack's early-1980s home-computer lineup.
