A Gen Z Mainframe
Adventure

oday's typical young
adults are occupied with
things like sports, arts,
online/mobile games, social
media apps and fashion. But
Connor Krukosky isn't your typical
Gen Zer-he has a mainframe in
his parents' basement.
An aspiring electrical engineer,
19-year-old Krukosky acquired his
first computer-what he believes
is an IBM Aptiva-when he was 18
months old and started collecting
vintage machines about three
years ago. In October 2015, a
note on the members' list of the
then-named Mid-Atlantic Retro
Computing Hobbyists group
(yhoo.it/1nWefWB) announced,
"IBM z890-Model 2086-320;
bidding so far
$100," and he
was hooked.
Krukosky replied
that he needed
something
to heat his
basement and
Moving the mainframe would definitely
into the basement. go for it.

has developed,

for decades.

T

Connor Krukosky's love for
vintage machines led to him
purchasing an IBM z890.

Skeptics noted the system's
doorway-busting size and weight
of over 1 ton, but he bid and the
beast was his for a mere $237.39.
The move included stripping
everything from the z890 frame,
using the family's small flatbed
trailer to transport it home and his
supportive father excavating under
their deck to slide the tight-fitting
frame into the basement.
Reassembly involved replacing
damaged heatsink thermal
compound, rewiring the z890
from three-phase to singlephase and configuring the
home's power panel for 220
volts. Hours of self-study and
abundant advice from members
of the IBM-MAIN discussion
mailing list helped create an
I/O configuration data set and
define a new LPAR. Then came
the need for storage, with fiber
connectivity (FICON*)/ESCON

About the IBM z890
Introduced April 7, 2004-the 40th anniversary of the System/360
mainframe-the z890 server replaced the z800 and allowed mid-size
enterprise customers an option based on the z990 technology. Read more
about the z890 in the System Overview: ibm.co/1PFrbaw.

gear too expensive and bus and
tag storage too hard to get. The
solution was an IBM storage-area
network (SAN) Data Gateway for
storage; Linux* is installed but
not yet running.
After all that, the big VM
or OS IPL hasn't yet happened. Fundamental Software
(funsoft.com) is lending a
FLEX-ES Control Unit Behavior
ESCON emulator.
An educated guess for the
system's original cost, a 2086320 model with 8 GB of memory
and appropriate I/O gear, was
about $340,000. Krukosky's total
project cost so far is about $340,
including thermal adhesive epoxy,
cables, the SAN gateway ($11.84),
etc., representing 0.1 percent of
the cost of the new machine.
IBMers have been informally
helpful, and Krukosky is exploring
whether z/VM* and z/OS* versions
might run. Next comes Internet
accessibility via a 3270 SSH and
a 3270 terminal via a 3174-61R
establishment controller.
With Krukosky representing
the next mainframe generation,
IBM z Systems* servers are in
good hands for years to come.
