I have two of the H19 terminals, they work pretty well. I did have problems with the HV diode going bad, but a replacement found on ebay fixed that pretty quickly. That may be the same problem with this unit.

If you can find the second (CPU) board (and some misc stuff) you can change it an H89 Z80 computer I seem to recall).

WordStar has a special config setup just for the H19.

Hi Walt,

Thanks for posting this! I had no idea Goodwill had on online site of this kind.
