VHD Interface and VHD PC Player both required for VHD games?

Both VHD player with vhdpc logo( so has that din13 connector) and VHD interface (e.g. Victor IF-7900) are needed. For Sharp X1 there is interface card VO-20PS, and then also interface unit VO-20PC. Both are needed. And if game is inside vhd disc only, then X1 needs also separate VHD language interpreter (software on tape). Here is link to one closed auction that still has pictures for those sharp stuff https://page.auctions.yahoo.co.jp/jp/auction/u1051261504

I think these interfaces are for using with a Sharp X1 computer (non-MSX).

This tweet makes a comparison with a specific R5-232C card for Sharp X1:

"A rare board that you might not know unless you write it as a VHDpc I/F board for X1. It's like adding an 8255 parallel port to the CZ-8RS with TTL level output."

Here's the mentioned CZ-8RS card:

This other tweet confirms that it's not for MSX:

"In addition to VO-20PS, connecting to a VHDpc player requires an external VO-20PC, and software that loads programs from VHD also requires VHD language player software, which is much more difficult than MSX."

That sharp x10b player has only that din-8 connector, that is likely only for Sharp X1 related VO-20PC (this has din 8).
Here is link to old auction with full Sharp X1 set with x10b player: https://page.auctions.yahoo.co.jp/jp/auction/g1057073564

In msx case there is 8 lines used for signals from din-13, so this din-8 wuold not have even enough pins to have also ground.
So most likely you need to get another VHD player that has din-13, e.g.Victor 7900.

Thanks for the info popolon_

What interfaces will work to play VHD Games that run from tape? According to the Wiki VHD Basic isn’t required for these games but the other interfaces just mention superimposing Karaoke. Not sure which will be compatible?

Thanks for the info. It seems the interfaces are also compatible Roth other computers because someone noted they were using one with a Panasonic MSX computer on another thread.
