My father (who was legally blind) received it from the Division for Vocational Rehabilitation and used it to write his book. For my father, this computer replaced an orange IBM Selectric II or III (not sure which).

			== Detailed Specifications ==

			=== Original ===
			* 4.77MHz AMD D8088 CPU
			* 64KB RAM
			* 2x 5.25" 360KB DSDD floppy drives
			* IBM CGA video card
			* Zenith Data Systems ZVM-122 monitor
			* Epson MX-80 printer

			=== First Upgrade ===
			* 30MB Fujitsu MFM hard drive
			* 512KB RAM (on an ISA expansion card)

			The hard drive was partitioned into 4 partitions and loaded with a copy of Zenith DOS, where the partitions were managed by ASGNPART as follows:

			* Drive C (volume label SYS) had DOS, Norton Utilities, WordStar, and a few other programs loaded on it
			* Drive D (volume label DOCS) had my dad's book and other documents
			* Drive E (volume label unknown) had my mom's documents and Personal Ancestral File database
			* Drive F (volume label SCRATCH) was used for scratch space

			At some point, my dad upgraded the machine with a VGA video card and monitor, and the Epson MX-80 printer was replaced with an IBM ProPrinter X24.

			After I took over ownership of the machine in 1991, the VGA video card was replaced with an ATi Graphics Solution Plantronics-compatible video card and the ZVM-122 monitor was pressed back into service. The remaining original floppy drive failed and was replaced with a half-height 360KB DSDD floppy drive. At some point, I reinstalled IBM PC-DOS 3.21 on the hard drive, on a single 30MB partition.

			I used WordStar 6.0, BASICA, PC Globe, DEBUG.COM, the Cosmi Top Ten Solid Gold games collection, Where In The World Is Carmen San Diego?, and many other applications on this machine. I became a huge WordStar geek in this era, in spite of my dad's urging to follow him to that dark place where Word Perfect was taking over the world. At that point, my dad had acquired an NEC PowerMate SX Plus machine with a 16MHz 386SX CPU, and was heavily into flight simulators and beginning to poke around the edges of Windows 3.0.

			=== Later Solarridge Era ===

			I stupidly pulled all the configuration jumpers off of the multi I/O card, rendering the machine non-functional for a time, as the jumpers were not documented on the card. A replacement I/O card was acquired from Edgar Digital and Electronics Surplus, and I installed MS-DOS 6.0 on it.

			Around the end of the Solarridge era, I acquired a 90MHz Pentium machine from Knapp Computer Systems, and the 5150 fell into disuse for a long period.

			=== Trailer Era ===

			The machine was once again upgraded with a VGA video card, as the ZVM-122 had failed and was stored in my mom's garage. In this configuration, I used Microsoft BASCOM on the machine, as well as VBDOS.
