The H-19 to H-88 kits changed later to H-19 to H-89 kits. I built both.
After the Floppy controller (Hard Sector) was released, the upgrade kits
could be ordered with the Floppy interface. Both my H-19 to H-88 kits came
with the serial card. Not sure when the H-88 disappeared from the line up
though.

The last H-89 I built was an "A". The CPU and TLB's came with RFI shields on
them. I still have that one. Runs a 4 MHz Z-80, Magnolia CP/M 2.2 and 3.0,
Magnolia 128K RAM drive, Magnolia 5"/8" floppy Controller and the Magnolia
Serial/SASI board. It still is a nice machine. Power supply upgrades were
also included.
