Sticker on PCB below ROMs says STB21.I'm dubbing this the "STB20 CD" in absence of any other identifier. The only sticker on the machine itself is of little use...
The blurb at https://www.computinghistory.org.uk/det ... t-Top-Box/ suggests a STB20 with CD-ROM was known.
Presume your main ROM is the two 1MB 3.61 ROMs combined, and the extension ROM is as dumped?
