There were EIAJ cartridges, N1700, N1500, Umatic and EIAJ reel to reel before Betamax and VHS. There was maybe seven to nine years of Betamax and VHS overlap of 405 TV (1976 or 1977 to 1985 in UK and Ireland).
The V2000 format hardly made it to the market as Philips had to keep putting off release due to manufacturing issues. It had piezo driven heads so could track at any speed or stationary.
I remember having the loan of both EIAJ open reel and N1500 or N1700 in 1979. I had a mono TV with the standard switch soldered in the 625 position, an added transformer and video in/out I added. So I never made 405 recordings.
The Betamax and VHS not only killed off EIAJ machines of all types, but the N1700. Umatics hence forth were only used in semi-professional applications were ther VHS was unsuitable.
It was obvious even before 1982 that V2000 and Betamax were doomed, even though Betamax may have still been produced till about 2001 or 2002.
I'd serviced or installed all sorts of video recorders in the late 1970s up to Umatics, but never even saw a V2000, ever. The craziest machine I saw and used was a portable Akai using 1/4" reel to reel tapes. It even did colour. Colour was rare on the EIAJ except the National version using a cartridge. It had to be completely rewound to eject and had a big stiff leader.
I had a company in the early 1980s buying black Thorn/Ferguson mono TVs without tube and adding amber or green CRTs from Fivre in Italy. It had only video and audio in. We removed the tuner and put our plate with logo there. I don't remember if the AV in was anything more than two sockets, one replacing the aerial. We sold hundreds to schools for Apple II and BBC machines. Nicer than the metal cube CCTV screens often sold with Apple computers then.
Back in the late 1970s the only multistandard customers were interested in was NTSC + PAL. The VHS and/or Betamax resulted in 4.43 NTSC due to VHS machines using the same colour under subcarrier for NTSC and PAL. Some of the VHS machines would play NTSC tapes at 30/60, but the subcarrier would be at the PAL frequency.
Thus AV monitor TVs that could do PAL, NTSC 4.43 and sometimes actual NTSC existed. Barco, being Belgian , were the king of Multi-standard AT TVs, but I never saw any doing 405 line. I don't even remember any monitoring of 405 in the BBC CTA in the mid 1970s. I think maybe 1972 was the last time I saw 405 lines.
