I wouldn't say it works fine. There are problems starting with item id of 47398575. There are many items where the API returns "null" (that is the complete body in the reponse). However, the items are there if you view them without the API (e.g. https://news.ycombinator.com/item?id=47398575).
Model 204 wasn't the first I used (it might have been the fifth or sixth). I was a member of a small team that wrote an interface to M204 from Unix workstations. Fun times. :-)
If I recall correctly, these were all before I used M204: datatrieve; a product that I'm not sure I can talk about; dbase II; dbase III; informix; and ingres. Quite a few others after M204.
DEC's datatrieve. Also one of the earliest pieces of software that I can recall having easter eggs. "HELP ME" and "HELP WOMBAT" being two that I can remember.
