Pretty sure the ZX Spectrum (also 128k) had some kind of CDROM adaptor, it worked via the joystick port IIRC.

A quick google didn’t tell me anything so maybe I imagined it.

I think you did imagine it, yes.

The Spectrum did not have 128kB until near the end of its life. It started out with a choice of 16kB or 48kB and that was all you got until 1986.

It also didn't have a joystick port. Nor did it have floppy disks (although 3rd party interfaces existed). Amstrad added joystick ports when it bought the product line and brand from Sinclair Research, soon after Sinclair launched the Spectrum 128, based on a Spanish model.

Yeah, it was definitely in the Amstrad era, not the rubber keyboard. Spectrum +2 / +3 had 128k, and joystick ports. The +3 had a disk drive.

I may still have imagined it.

Okay, I did not imagine it - https://spectrumforeveryone.com/features/inside-codemasters-...

But it's not really a CDROM.

:-o

Wow! I defer.

A CD not a CD-ROM, but you're right.
