Differences between Sanyo VM-4209 and VM-4092 monitor

I always see the Sanyo VM-4209 being the sought after monitor to be used with the Apple-1.

 

The VM-4092 looks very similar, does anyone use this model with their Apple-1? I see the VM-4092 doesn't have a power LED. It looks like it has a 12V DC input which would be handy for non-US users. Does anyone know if there are any other differences?

Well I took a quick look and

Well I took a quick look and the original monitor for my 1976 Apple-1 is a vm4092 dated 1976. One of my 1977 Sol-20's from the original owner came with a 4209, dated 1977. So I guess both were used with hobby computers, one might have been cheaper? Maybe in 1977 they added an LED and changed model numbers?

Anyone have a 1976 dated VM4209 not a VM4092?

Cheers,
Corey

Yes it has a 12V DC

It actually says AC 120V 27 watts, DC 12V 12 watts

 

Date is June 1976

 

Since my Apple-1 was purchased originally from the byte shop, it'd not first 50, it's an NTI.   It has the original byteshop Koa wood case, datanetics keyboard and triad supply, so the monitor was most likely purchased at the same time since I was told what I got was everything the original owner bought from the byteshop.

Thanks Corey, do you have

Thanks Corey, do you have schematics for this monitor?

 

I'm still not sure what type of DC connector this is. I was thinking of replacing with a panel mount DC connector instead.

I have the VM4209 service

I have the VM4209 service manual in PDF, but it seems mostly accurate for the 4092 with minor differences.  PM me your email,
