    The 5171 is listed as the TEMPEST variant of the 5170. Note all the extra metal mesh covering the drives which should reduce the amount of emissions so no one can snoop on the operations.

    http://bitsavers.org/pdf/ibm/pc/IBM_..._4.0_Sep88.pdf page 153 shows the 5167-001 as TEMPEST Mono Display and 5171-168 as PC/AT Tempest. Someone didn't take security seriously.

    The next page shows that the 3270PC was 5271 and 3270PCAT was 5273. The document shows a few other interesting albeit rare IBM models like the PC/AT G/GX which was available with a 19" monitor.
