5271 first power

What I tried

Inspected the 5271’s PSU. It looked fine and stayed original. Then I swapped video cards around between the two machines to get the 5160 live on the 5153 with the best of what I had. It took a few tries. An EGA card in CGA mode is what finally worked on that monitor. With the 5160 settled, the 5271 got a VGA card and came up next, with the Inboard 386 still installed.

What I measured

Both machines POST. The 5271 shows ERROR at boot with no code and continues.

What broke or surprised me

The 5153 is pickier than I expected about which EGA card it will show a picture from.

Next

Hard drives.
