This is about my IBM PS/2 Model 25-286. It has a 10Mhz Intel 286 CPU and 1MB RAM. It also has a Lo-Tech ISA CompactFlash Adapter  (https://www.lo-tech.co.uk/wiki/Lo-tech_ISA_CompactFlash_Adapter_revision_2b) and an Etherlink III network adapter.

Special thanks to ClassicComputers.info for the scan of the Model 25 Technical Reference that helped me figure out which pins to tap on the floppy connector to provide power to my CompactFlash reader. (http://classiccomputers.info/down/IBM_PS2/documents/PS2_Model_25_Technical_Reference_Jun87.pdf)

Also, thank you Michael Brutman (https://www.brutman.com/mTCP/mTCP.html) for his excellent mTCP stack for tiny microcomputers like the one seen in this video!

I use the following CompactFlash reader in the system: https://amzn.to/2V4Wfxf
