You should have hollered if you needrd an expander. I still have two four port jobs (Aprotech) - I am still using an old Cardco 5 port job, that will not part with.
My 128D is still being patched up, so I am using a flat 128 with Jiffy DOS (one 1571 & one 1581 also J DOSed), and the video RAM upgrade.
I use dBase II in CP/M (using a 1Mb 1750 as a RAM disk), still my favorite even with the Amiga, and Windoze machines here.
My grandchildren use GEOS a lot, so end up helping them. That brings back memories..... Looks good through the HP 4 laser.
The 8 bits can still get a lot done.
