Retrotronik RAM card for HP 48GX

[rprosperi]

I have 2 of the 128K cards and have had no problems at all with either, using them in both 48SX and 48GX machines (more than one of each).

I have not checked-in with the seller in a couple months, but last I heard there were some delays on the 1MB and 2MB cards, due to COVID, affecting both his family and also suppliers. I'm not sure of the current status, but I'll try to prod him for a project update and some availability dates.
