The '''Radio Shack TRS-80 Micro Color Computer''' (also called the '''MC-10'''), first made available in 1984, was a small home computer in the era's typical "combined computer and keyboard" form factor. Tandy intended it to compete with the Timex Sinclair 1000, the low-price leader in US home computers at the time.

Despite sharing the "TRS-80 Color Computer" branding with the CoCo, and using the same [[Video Display Generator|Motorola MC6847 Video Display Generator (VDG)]], the MC-10 had significant differences with its bigger and older sibling, most notably in having a weaker and cheaper Motorola 6803 CPU rather than the CoCo's famously brawny [[6809]]. As a result, the two computers did not have full cross-compatibility, requiring at least some conversion/translation to be able to run each other's software, if at all.

The MC-10 did have the same cassette port used by other TRS-80 computers (such as the CoCo, the Model I/III/4, and the Model 100/200/102) and could use the same cassette cable (Catalog Number 26-1207) and computer tape drives they did, including the [[CCR-81]], [[CCR-82]], [[CCR-83]], and others.

The MC-10 also had the same 4-pin DIN serial port used by the CoCo and could use any [[CoCo Printers|CoCo-compatible printer]] or [[CoCo Modems|modem]]. Still, when launching the MC-10, Radio Shack also introduced a printer that, while CoCo-compatible, was intended especially for the MC-10's presumably cost-focused customers: the [[TP-10]], a small and cheap ($99) thermal printer using 4⅛" wide paper, which printed text at the exact 32 character line length provided for by the VDG the CoCo and MC-10 used. This printer was confined solely to CoCo and MC-10 use because - alone among Tandy/Radio Shack printers during the CoCo's run - it ONLY had a serial port (and the CoCo/MC-10 4-pin DIN variety at that), cutting costs by omitting the then industry-standard Centronics parallel printer port.

Although the MC-10 was "cute" and cheap, it was not well-suited for children because it had neither joystick ports nor a cartridge slot (although an enthusiast project has been able to use the expansion slot as a de facto cartridge port; [[MC-10_Micro_Color_Computer#Zippster_Zone|see the Zippster Zone section below]]). It was instead primarily aimed at electronics hobbyists (one of them had an MC-10 team up with a CoCo to control a robot derived from Radio Shack's popular Armatron robotic arm [https://archive.org/details/color-computer-magazine-1983-12/page/n21/mode/2up]) and first-time computer buyers who wanted to learn to program. Accordingly, its version of BASIC was powerful and its small keyboard enabled entire commands to be entered with minimal keystrokes.

While the MC-10 arguably made sense when Tandy began the project, the computer landscape was changing particularly rapidly at that time (even by the overall historical standards of that industry), so that by the time the MC-10 actually came out, the market had already changed due to various factors such as [https://en.wikipedia.org/wiki/Video_game_crash_of_1983 video game crash of 1983] and the [https://en.wikipedia.org/wiki/History_of_personal_computers#Commodore_price_war_and_crash Commodore-driven price wars] driving the price of mid-range home computers down much closer to the low-end MC-10's price point. With those pressures and a weak lineup of officially released software at time of launch, the MC-10 sold poorly; Tandy almost immediately gave up on it, releasing no new software or accessories and slashing the price to clear out the existing inventory.

The MC-10 was discontinued in 1985.

Dungeons of Daggorath

2005-03-06T04:50:44Z

Curtisboyle:

One of the best (and best selling) games that Radio Shack ever sold for the Coco. Hugely innovative for it's time, Dungeons of Daggorath was a real time dungeon romp, with 5 levels, and sound effects far beyond any other such game of it's day. You had a real-time heartbeat that was affected by battle, how fast you ran, when you were attacked, etc., and monsters actually got louder the closer that they got to you. It had such a huge influence that a PC port has been done, and entire webpages have been devoted to it. It was release in cartridge format in 1982, and the entire program was crammed into an 8K ROM.Douglas Morgan, one of the original authors, has mentioned that a larger, more sophisticated version was originally done, but it had to be compressed to fit on a cartridge. It is too bad that the original version has not survived...[[Image:dungeons_of_daggorath_intro.gif|thumb|center|Dungeons of Daggorath Intro screen]]

"One to four wheeler-dealers pick drilling sites. A surveyor's report gives the chances of striking oil. Watch out for dry holes! Hit a gusher and you're in the money - for a while, anyway. Production soon decreases, and taxes and drilling fees start to mount. Earn the highest profits in 10 rounds to win" 
It was released in fall of '82, with a SRP of $29.95 [[Image:Wildcatting.gif|thumb|center|Wildcatting screenshot]]
