The
IBM 5150 Personal Computer features an 8088 Intel processor, 256k of
memory
on the motherboard, and a monochrome display adapter driving a 5151
green/black
monitor. It has two full height IBM 5.25" 360k floppy drives, and no
hard
drive. I have an original IBM DOS version 1.10 with it, which
runs
from one 160K floppy disk. The original IBM 5152 printer is an Epson
MX-80
with the IBM label. This whole setup would have cost you around $4000
back
in 1983.
This
5160 Personal Computer XT (eXTended) came equipped from IBM with lots
of
good stuff, including 256k RAM on the motherboard, plus a 256k RAM
expansion
card (with "flipchip" IBM 64k x 8 chips), an asynchronous
communications
port, one 5.25" full height IBM 360k floppy drive, a 10m IBM (Seagate
ST-506))
hard drive, and a Color Graphics Adapter driving an IBM 5153 color
monitor,
plus the Monochrome Display Adapter, which also drives the printer. I
have
the original IBM Guide to Operations, which includes the diagnostics
disk,
and a cool "getting to know your IBM PC" educational disk. This one has
IBM DOS 2.10 (1984) loaded on the hard drive. This computer does
NOT have a real time clock, you must enter the time and date every time
you boot it up. I have an AST Six Pack Plus memory/clock/comm/gameport
board, with the software and manual, but I don't want to put any
non-IBM
cards in this computer, as it is just too original to mess with.
Now
we
can watch Beavis and Butthead over netflix, on the big screen!
This
is the computer I'm using to make this web page...a slightly modified
IBM
PC XT Model 286 (5162). The original motherboard was missing when I got
the computer from the thrift store, so I installed a PC Chips M755LMR
board,
with an Intel 1 gHz Pentium III processor. It has 128 Mb of ram (as
opposed
to 256Kb on the original), along with 1 Mb of cache. Other features
include
a Maxtor 40gb ATA-133 hard drive, 3.5" floppy drive, 8X/4X/32X CD-R/RW
drive, onboard sound, external 33.6kbps modem, a 2Mb Trident
PCI video card, and a PCI network card. The new motherboard fit just
fine,
because it is just a bit shorter than the XT board, and the XT/286 157
watt power supply seems to have plenty of power. I like the small IBM
keyboard,
which is early 90s vintage (an option on the PS/2 computers), and has
no
numerical keypad to get in the way of the mouse. The operating system
is
Windows 2000. You can see that it's a sort of tight fit inside. See my Dynaco page for more
information about the amplifier that feeds the Technics speakers.
This
is an IBM PC/AT (Advanced Technology) Model 5170 computer. It was at
the
thrift store, and apparently came from the University of Arizona
Optical
Sciences department (where my brothers worked around 1980). It has an
IBM
EGA video card, here set to work with the standard IBM 5153 Color
Display.
I finally found an original IBM 5154 Enhanced Color Display for it, not
pictured here. The computer has an 8 mHz 80286 processor, running at 6
mHz, and the full capacity of 512 kbytes of memory on the motherboard.
It also has an IBM 30 mb hard disk, and the original 5.25" high density
floppy drive. Note that the original cover is still there for the
optional
floppy drive, usually the cover was thrown away when a 3.5" drive was
added.
There is the original IBM disk drive controller board inside, this is
an
extra tall full length board, as it controls both the floppy and hard
drives.
There is also a Paradise I/O board, with one 9 pin RS-232 port and one
parallel port. I added some extra RAM on two BocaRam AT boards,
including
128k of conventional, and 3 Mb of extended memory. It has the original
DOS 3.30 on it, and I added Windows 1.01 just for fun.
