Text and graphics were displayed on a televisionset via a built-in RF modulator. Less common for machines in its class was theintegrated RS-232 serial port, which allowed the MC-10 to use a wide variety ofline printers and modems without additional hardware.Even so, at the timeof its release in 1983, the MC-10's specifications were underwhelming. Diskdrives, full-travel keyboards, medium-resolution graphics, and complete64-kilobyte memory banks were becoming popular features for home computers; theMC-10 offered none of these, severely limiting the functions it could performand the range of users to which it could appeal.The MC-10 wasdiscontinued in 1984, along with the 16 kB memory upgrade and small amount ofcassette-based software that had been released for it. It never achieved a widefollowing.SpecificationsVDG: MC6847 Text:32×16Low-res: 64×32, 8color (4bpp)Low-res: 64×64, 4color (2bpp)Med-res: 128×64, 2color (1bpp)Med-res: 128×64, 4color (2bpp)Med-hi: 128×96, 2color (1bpp)Med-hi: 128×96, 4color (2bpp)Hi-res: 128×192, 2color (2bpp)Hi-res: 128×192, 4color (2bpp) (required memory-pak)Hi-res: 256×192, 2color (1bpp) (required memory-pak)I/O Ports: RS-232Cserial interface (300-9600 baud; 600 baud from BASIC)Cassette interface(1500 baud)Internal RFmodulatorMemory expansioninterfaceAlthough the memoryexpansion interface connected directly to the CPU bus and could have been usedfor many applications, the edge connector involved had an unusual number ofpins and was difficult to obtain.The RS-232C serialinterface had extremely limited usefulness. Although the 6803 CPU convenientlyincludes a built-in UART, it was not connected to and did not assist theRS-232C interface in any manner. In part, this was because a single 3.58 MHz TVcolorburst crystal was used to generate video and clock the CPU, and this clockrate did not correspond to any standard baud rate when divided for the UART. Asa result, programs had to shift all bits individually into and out of theRS-232C interface, creating artificial and especially critical timingconsiderations.The cassetteinterface had similar difficulties, plus a few. Although Micro Color Basicincluded an undocumented CLOADM command for loading machine-language programsand an undocumented VARPTR function for manipulating variables as memory, therewas no corresponding CSAVEM command (documented or otherwise) to permit machinelanguage programs to be saved to tape.SoftwareA limited amount ofsoftware was available on cassette for the MC-10, including Lunar Lander,Checkers, and a machine-language Pinball program. However, as most programswritten in Basic for other TRS-80 models were compatible with the MC-10, manybooks with BASIC programs were available for the user who was willing to typein the code.
