The CPU in the Eazy PC is an NEC V40 microprocessor running at a clock speed of 7.16 MHz, but able to be slowed to the 4.77 MHz speed of a standard XT. Like the NEC V20, the V40 is object-code compatible with the Intel 8088, but the V40 includes some integrated peripherals that would otherwise require additional circuitry on the mainboard. Base system memory is 512 KB of RAM. The BIOS used was both designed and supplied by Vadem.
The mainboard was noteworthy among contemporary IBM PC compatible systems of its class for its extensive use of large scale integration (LSI) ICs and low-power CMOS chips—as ZDS had been using in their portable computers. Locating the system power supply inside the monitor permitted a smaller mainboard enclosure.
Once purchased, the configuration of the drives could not be modified—even to add a second floppy drive to a Model 1—except by ZDS themselves. Models 1 and 2 were equipped with lower-wattage power supplies unable to support the addition of a hard drive. The components inside Models 1 and 2 were also arranged differently from the Model 3, in a way that makes it impossible to install an aftermarket hard drive.
The Eazy PC's only aftermarket options were sold by ZDS, and included a mouse, an internal real-time clock module, and two external modules. External modules have metal enclosures and plug into the rear option port, extending the depth of the computer's case by 2.5 inches (6.4 cm). One module expanded the RAM by 128 KB to the supported maximum of 640 KB. The other module included the additional memory, and added a 9-pin serial port and a 300/1200 bit/s modem with a 6P2C RJ11 socket. Only one external module could be attached at a time.
ZDS marketed the Eazy PC as an "entry-level machine", suitable for "novice or first-time computer users" and "business executives who bring work home". This was the company's first effort to attract a base of consumers who had rarely or never used a computer before. ZDS had previously earned a reputation in the computer industry for producing high performance systems—especially portables—and were a major supplier to governments and institutions. Initial pricing in the United States ranged from $999 to $1699 ($2,765 to $4,702 in 2024 dollars), depending on the configuration chosen. The memory+serial+modem expansion module—which one reviewer considered necessary for the PC to be useful at all—cost an additional $399 (equivalent to $1,104 in 2024).
ZDS discontinued the Eazy PC in early 1990. At least one discount catalog company, Damark, offered the Eazy PC with the hard drive configuration for $669 (equivalent to $1,610 in 2024) as late as September 1990.
Perdue criticized the Eazy PC as "neither simple enough for novices nor powerful enough for business users", and strongly disliked the lack of upgradability. Except for word processing, he found the Eazy PC inadequate for any other purpose, citing its instability when testing several popular IBM PC programs on it and lack of support for local area networks—severely limiting its usefulness in schools and businesses. Perdue wrote that the memory+serial+modem module performed well but suffered from a loose connection to the main chassis due to the thumbscrews attaching it being too short. He also called the built-in monitor's grayscale rendering poor, requiring constant adjustment of the contrast knob to read text between the interfaces of different programs. The only high mark Perdue gave the system was in setup—he was able to unpack and get the Eazy PC running in roughly 10 minutes.
