YAHAMA DX7 MK1 INFO/REVIEWS BELOW:
I am sure if you are looking at this ad, you already know everything you need to know about this amazing keyboard. But just in case; this is THE main player in producing almost every hit song of the late 80’s! This wonder is adored by all collectors, and will keep on going up in value. It is truly ONE OF THE BEST keyboards of ALL TIME! When it came out, in 1983, it had a price tag of $1995.00!!! At that time, you could have bought a new car for that!!! Needless to say, like most kids, I didn’t get one from Santa! 😉 One of the most iconic keyboards of all time; a game changer! It shaped the 80’s electronic music genre/scene! At its time, it was the most powerful, most impressive and most advanced synthesizer available; a must have for every studio and music producer; and that made it the most successful keyboard of ALL TIME! It has been a key part/creator of many MEGA HITS, and has appeared in countless MUSIC VIDEOS!
The sounds it produces are so crisp, and heavenly; that are still relevant to this date; a true wonder…
The Yamaha DX7 is a digital synthesizer that was first introduced in 1983. It was the first commercially successful digital synthesizer and is considered to be one of the most iconic and influential synthesizers of all time. Here are some of its key specs:
Polyphony: 16 voices
Oscillators: 6 sine wave operators
Filters: None (uses a frequency modulation synthesis technique)
Effects: None built-in, but it can be used with external effects processors
Keyboard: 61 keys (velocity and aftertouch sensitive)
Memory: 32 patches (user programmable)
Sequencer: None built-in, but it can be controlled by external sequencers
Connectors: MIDI In/Out/Thru, stereo outputs, foot pedal and breath controller inputs
One of the defining features of the DX7 is its frequency modulation synthesis (FM synthesis) technique, which allows for a wide range of complex and evolving sounds.

CX5M INFO BELOW:
The Yamaha CX5M is a vintage computer system that was introduced in 1984. It was designed to be a music production system and included a built-in FM synthesizer, the same technology used in the popular DX7 synthesizer. Here are some of the key specs and features of the CX5M:
Processor: Z80A CPU running at 3.58 MHz
Memory: 64 KB RAM (expandable to 128 KB) and 48 KB ROM
Operating System: MSX BASIC
Audio: Built-in 4-operator FM synthesizer with 8 voices and 16 pre-programmed sounds
Video: Built-in V9938 video chip with 256 KB VRAM and support for up to 512 x 424 resolution
Storage: Built-in 2DD 720 KB floppy disk drive
Expansion: Two cartridge slots, one for ROM cartridges and one for RAM cartridges
MIDI: Built-in MIDI interface
The CX5M was marketed as a complete music production system and came with software that allowed users to compose, arrange, and record their own music. The system was compatible with MIDI equipment and could be used as a controller for external synthesizers or sound modules.
One of the unique features of the CX5M was its ability to expand its memory and functionality with cartridges. Yamaha released several cartridges for the CX5M, including additional sound libraries and sequencers.
Overall, the Yamaha CX5M was an innovative product that bridged the gap between computers and music production. While it may not be as widely known as other vintage computer systems, it remains an important part of the history of electronic music production.

FD03U INFO BELOW:
The Yamaha FD03U is an external USB floppy disk drive that was released in the early 2000s. It was designed to be used with computers that did not have built-in floppy disk drives, such as newer laptops and desktops. Here are some of its key specs and features:
Interface: USB 1.1

It was easy to use and did not require any external power source as it was powered by the USB connection. The drive could read and write 720 KB and 1.44 MB floppy disks, which were the two most common sizes used at the time.
YAMAHA DOM-30 DISK ORCHESTRA MODULE
SERIAL NUMBER: 002958
ORIGINAL MSRP: ??
ESTIMATED CURRENT VALUE: $200
UNIT IS IN EXCELLENT CONDITION – DOES NOT INCLUDE OROGINAL POWER SUPPLY BUT IT IS COMMON AND CAN BE PURCHASED ONLINE
INFO BELOW:
The Yamaha DOM-30 was a MIDI sound module that could be connected to a computer or MIDI controller to produce a variety of sounds, including orchestral instruments, percussion, and sound effects. It featured a built-in disk drive that could load and play back MIDI sequences stored on floppy disks, hence the name “Disk Orchestra Module”. The DOM-30 had 16-voice polyphony and a range of effects, such as reverb and chorus, to enhance the sound of the MIDI sequences.
The DOM-30 was designed to be used with a computer and MIDI sequencing software, such as Yamaha’s own QY10 music sequencer. It was a popular choice for home musicians and hobbyists who wanted to create and arrange music using MIDI instruments and sequences.
I couldn’t find any reliable information on the Yamaha DOM-30’s manufacturer’s suggested retail price (MSRP), as this product is quite rare and was likely sold only for a limited time. However, it may be of interest to collectors of vintage synthesizers and digital music equipment.

” This sale is for the Yamaha CX5M MSX Music Computer sold between 1983 and 1986. I think this was an early version of this computer and therefore think the data of manufacture is 1983 or 1984. I think this principally because it has a power brick and later versions had the transformers inside the unit. This unit was sold in Europe and is therefore configured for a 240V AC supply. A picture of the rating on the power brick is included.”
