My first monitor was, but I upgraded (and it cost a lot) to a 13 inch CGA monitor. It was awesome!
Getting a bit off-topic, but my first computer was a Timex/Sinclair ZX (a $99 product that was a collaboration between the watch company and Sir Clive). It had a Z80 8-bit CPU that was clocked at 1KHz (that's not a typo), came with 4K of RAM, expandable to 16K, used an audio cassette deck for program and data storage and a standard television as a display. It came with BASIC included. It was a little on the slow side.
My next computers were a couple of Commodore 64s, which used some kind of Motorola CPU (I don't recall which one at this point) clocked, if I recall correctly, a 1MHz, had 64K of RAM, and actually had available 5-1/4" floppy disk drives for data and program storage. There were MIDI interfaces available for these, as well as primitive sequencing software, and I used one of them for this purpose. It, too, could display on a standard television but there were also dedicated composite-input monitors available for it. Originally, they were green screens, with long persistence phosphors. Eventually, amber screens became available.
I then graduated to an IBM XT, the successor to the original IBM PC. It came stock with 64K of RAM, which I expanded to a whopping 512K with a rather expensive expansion card. It had an Intel 8086 CPU that clocked at 4.7 MHz, and a true mother board, which allowed for system expansion. It also had available a "Winchester" hard drive with a storage capacity of 20 megabytes. These were called "Winchester" drives because they had 20 platters and stored 20 meg, i.e. 20/20. Roland introduced the venerable MPU-401 MIDI interface, which was the first de facto MIDI standard interface for PCs, and that was when I was first introduced to Cakewalk which, of course, grew up to become Sonar. It was also on this machine that I ran my first amanuensis software -- Personal Composer, which is still around.
