Both machines booting

/ IBM 5160 and 3270 PC bring-up ibm xt 5160 5271 dos

What I tried

The other good ST-251 into the 5160 on its own controller card. Different card from the 5271’s, so a different format, but the same process through DEBUG. FDISK, FORMAT, DOS 5.

What I measured

Both machines boot from A: and from C:. On the 5271 I loaded DOS and typed around with the Inboard in. If the Inboard didn’t work, the machine wouldn’t.

What broke or surprised me

Nothing.

Next

The Inboard’s DOS utility. The alignment tool. Eventually the 3270 side.
