IBM PC AT 5170 Type 1 with early BIOS (27128 IC type)

ibmpc5150 · December 2018

I've got junk of IBM PC 5170 type 1 motherboard.

This is very early Type 1 release of IBM PC 5170 BIOS.

Part No. : 6181024 (16KB) + 6181025 (16KB) = 6181028 (32KB) , 6181026 (16KB) + 6181027 (16KB) = 6181029 (32KB)

Cool.
Nothing to say about.
It looks clean.

Unfortunately motherboard is still broken, but BIOS was dumped.
