I sold a lot of those upgrades back in the day to corporate
customers in the IBM 9556 / 9557 / 8556 / 8557 microchannel PS/2's.
Seems like they were used in POS environments like pharmacies, etc.
Nice one!  |

Thanks for the info Glory_Cloud. I'm able to see inside some old POS systems so I will take a look around

The PS/2 8856 / 8557, yes. These were the original model 56 SX / 56 SLC / 57 SX / 57 SLC made in 1991 or 1992. The PS/2 9556 / 9557 were later designs which came with the 486SLC2 or 486SLC3 factory installed. Nice MCA machines, too.
I may have more of these upgrades in the near future.

| Do you think it will work with an Intel 387SX or only with 387SL ? |

I think it doesn't really matter. These PS/2 models came with Intel 387SX usually.
