Retrotronik RAM card for HP 48GX

[jonmoore]

I already have a 1mb card for my 48GX (and this is more that enough for me) but I really want a 128k card to split my Port 0 (SpeedUI) load, and Samson Cables charge a huge premium for 128k cards (it works out at cira £200 with duties, courier etc), so I'm wondering how folk have got on with these Retrotronik cards?

It appears on the website that new stock on the 1-4Mb cards will be happening cira late August (although that might be an old 2021 message), but there's nothing mentioned ref the 128k cards.

I did send a couple of PM's to the vendor but got no reply so I'm also hoping that @jcrbarbosa will see this post here and will be able to provide updated info in this thread.

@rprosperi, I'm specifically interested in your feedback (if possible), as I know you make heavy use of your 48's.
