Summary

This was my first computer. My father (who was legally blind) received it from the Division for Vocational Rehabilitation and used it to write his book.


Monitor

When I had it, this machine had a Zenith Data Systems ZVM-122 monitor, a green phosphor composite model.

Historical Summary

Note that the information presented in this section was retrieved from my old personal website, The VAX Pirate's Lair, and is not likely to be entirely accurate or timely. Spelling errors have been kept intact for the purposes of historical preservation.

Note: I realize now that IBM regularly sourced processors from AMD for these machines, and so the system planar on this machine was actually original.

This is the granddaddy of the x86 architecture: an original IBM PC. The real thing. Purchased in 1984 as my family's first home computer, it was passed to me in 1991 when my father upgraded to a shiny new NEC 386. I remember this machine having two ful l-bay 5.25" DS/DD floppy drives and a green-on-black CGA monitor. It was upgraded in approximately 1986 with a 30MB Fuji (not Fujitsu) MFM hard drive. It still works like a charm, albeit very slowly. The hard drive is loud, the power supply squeaky, and t he processor, plodding along at a dismal 4.77MHz, is slow. But, this computer is a joy to play with and write BASIC programs on, and reminds us of a time when multitasking and graphical user interfaces were unheard of. This computer is running IBM PC-DOS 3.21, and has WordStar 3.3, WordStar 6.0, Norton Utilities 1.2, IBM BASIC compiler, and a games pak. At some point the motherboard was replaced because the processor is not an Intel. I think the original IBM PC motherboard could only accommodate 64KB RAM on the system board, and this one has support for (and is loaded with) 256K

  • IBM Personal Computer (5150)
  • Advanced Microdevices D8088 processor (not sure why or when this was put in)
  • 512K RAM (256KB on the system board, 256KB on a memory expansion card)
  • 30MB Fuji MFM hard drive
  • ATi Small Wonder Graphics Solution video card (basically enhanced CGA)
  • IBM PC-DOS 3.21
