The TRS-80 actually used cartridges.
Iirc you could purchase a tape recorder or floppy drive as seperate peripherals, but I never had either.
Nope. The original TRS-80 like I had (4k, yes, k of memory!) used a tape recorder and cassette tapes for storage. It was REALLY crappy and often would misread.
The Color Computer, with its Motorola 6809E processor, was a radical departure from the Z80-based TRS-80 Models I/II/III/4/4p. Indeed the "80" in "TRS-80" stood for "Z80". For a time, the CoCo was referred to internally as the TRS-90 in reference to the "9" in "6809". However this was dropped and all CoCos sold as Radio Shack computers were called TRS-80 in spite of the processor change.
The CoCo, which could display eight colors at once, was designed to be attached to a color television set, whereas the Z80 machines used monochrome computer monitors, often built into the case. The CoCo also featured an expansion connector for program cartridges (mostly games) and other expansion devices, such as floppy disk controllers and modems. In this way it shared some similarity to the Atari 2600, Atari 400/800 and other cartridge-capable game consoles and computers.
I meant the TSR-80 CoCo (Color Computer). I think mine had 16 or 32k memory, but I don't even remember which revision it was. The naming was somewhat confusing because they had several computers that were called the "TSR-80".
By the way I wish more companies did what SSI did; stick with a known game engine and WRITE GAMES with it. They improved it a tiny bit with each game and it was getting a bit long in the toot at the end but they were still great games.
There was a screw you could tune up atleast in C64 tapedriver. If that didnt work then there was always praying. Som games took up to 25min to load and they could fail on the last minute.
Some floppy disks (I always say "disquettes" ) even had a copy protection.
My Blues Brothers Jump & Run game couldn't be played without the disk in the drive.
