Period Press

Every issue below survives only because worldradiohistory.com scanned and hosts it — the mirrors here are single- and two-page pulls from that archive, kept local in case the source ever goes away, always credited back to it. Where a sighting is more than a price row, the X-150D-relevant passage is transcribed as an excerpt; where it's a dealer price or a directory line, the whole thing is quoted below instead, in the entry's own description. The history page cites and links to every entry here as it builds the model's timeline.
