This is a fun computer, a find for vintage computer collectors


Vintage-Architecture CP/M Desktop Computer System. This hardware unit features a Z80 processor and integrated graphics. 


This hardware system was recently assembled a month ago, in 2026, using original, unused factory-stored parts including the case, power supply, dual 5.25" floppy drives, CPU board, video board, and keyboard. 


Except for testing, it has not been used. After assembly, the unit was tested and is fully operational.


Historical Context & Provenance:

Originally developed in 1986 by Goldenrod Research Corp for its own use.

Technical Specifications:

- Processor: Z80 CPU

- Video Architecture: Integrated graphics (Derived from historical Morrow MD3 circuit designs)

- Storage: Dual 5.25" floppy disk drives

- Input: Included matching keyboard

- Ports: 25-pin Serial Port and 36-pin Centronics Printer Port

- Physical Dimensions: 19.5" L x 6" H x 16" W

- Manufacturing: Made in the United States

- Monitor Requirement: Requires an external monitor with a 9-pin input (such as vintage CGA or EGA displays) to operate.


Included Software & Media:

Includes a physical system startup disk formatted for this CP/M architecture. The disk contains legally compliant public domain/system utilities designed for this vintage operating system. A cross-platform format utility is included which handles several of the standard formats from the era.


I will secure the drive heads for shipping with a cardboard insert in the floppy drives.

### ⚠️ Technical Terms of Sale & Return Policy – Please Read Before offerding


Due to the specialized, historic nature of 1980s CP/M computer hardware, this item is sold under the following strict terms:


* **Technical Knowledge Required:** This is a vintage command-line CP/M system. It does not possess a modern graphical user interface (GUI), USB ports, or plug-and-play architecture. The buyer is entirely responsible for possessing or researching the technical knowledge required to operate vintage Z80 architecture, CP/M terminal commands, and legacy 9-pin video configurations. Returns will not be accepted for "user error" or an inability to operate the software.

* **Vintage Component Disclaimer:** While this unit was built using pristine, unused New Old Stock (NOS), and itpasses all current bench testing, vintage silicon, capacitors, and floppy drive alignments are inherently fragile. 

* **Return Policy:** To protect the integrity of this scarce hardware, this item is sold AS-IS with no returns or refunds unless damaged in transit. 

* **Shipping & Delivery Inspection:** This unit will be heavily insured and packed to industrial standards. Upon delivery, the buyer must carefully remove the cardboard transit inserts from the floppy disk drives BEFORE powering on the machine. Operating the drives with the shipping inserts inside can instantly burn out the vintage motors and voids all seller transit liability.
