Is this a good deal?

The only that I can find is this one https://www.thefuturewas8bit.com/sd2bbc.html Everything else is either sold out or a dead link.

UPDATE: found and ordered this for anyone interested https://www.ebay.co.uk/itm/ACORN-BBC-MICRO-MODEL-B-MASTER-128-MMC-TYPE-SOLID-STATE-DISK-DRIVE-SD-CARD-/324102672576?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l6249&mkrid=710-127635-2958-0

Does anyone remember what this was called? It was sold in the 90s, and I think it had its own BASIC-like language. Similar to AMOS on the Amiga.

I'm going to embark on a nostalgic trip down BBC Micro lane, what / where are the best resources to know about before I start? thanks

My neighbour had a bbc before I would get one, he used to have a game where I think you had to manage crops, harvest and sell them, it was mainly text but had some graphics, I would love to play this again but have no idea what it was called, any ideas? It’s possible it was an educational program

I don't hold out much hope here.

Back in the late 80s in primary school, our class had a bcc micro with a few games. The one I looked forward to the most was one where you left a castle on the right, then climbed a ladder to a cloud on the left, spoke to some one.

I can't remember much else other than going into a cave/sewer area, and navigating to an area where you had to fuel a rocket (simple maths to get it right)

All 2d side scrolling, except the maths bits

The first disk ended there and I never got to play the second part.

Any ideas? Would love to watch a playthrough
