I can't find anything about this card, the ports on the back marked To Video-In and To Video out (RCA) and a spot for a remote

What is it?

Some sort of Video Capture Card perhaps?

According to the FCC lookup E5Z5K3AM-614 was made by an Alpha Microsystems, 3501 Sunflower Santa Ana, CA 92704. The FCC granted their request on 10/26/1987. Unfortunately there is no documentation accompanying this on the FCC website.

I'm not sure it's the same company, but here's a link to documentation of alpha microsystems products link (http://www.alphamicroproducts.com/amphtm/docs.htm#idxtag011)

Dunno, but I bet Cameron Kaiser (ckaiser@floodgap.com) at Floodgap might have an idea... Alpha Micro made a bewildering number of products over the years.

And the logo looks similar to that on the board. Alpha Micro has been a long time vendor of multiuser computer systems. It is probably one of their backup cards or such.

Is there a number above the Alpha Micro silk screen on the top left by the bracket? Are there other connectors besides the two RCA plugs? It looks like that big silver can in the top left has an opening in the bracket too.

DWB-00614-00 is the number that can't be seen in the shot,

The big sliver box is for a remote so it says 20 pins.

Hi! I am going out on a limb here and guessing its one of those "backup to VCR" peripherals that were briefly popular in the 1980's. It certainly does not appear to be a video card and the chips suggest to me a high speed data encoder/decoder. Of course, that's a guess.

I hope this helps. Thanks and have a nice day!

That's a good guess, there's a high-speed video switch on there (TDA 5850) and a couple of high-speed comparators (LT1016).
I can't really make out any other chips, other then TTL glue logic and such, and the big custom Motorola Monstrosity.
Does the shiny thing have a part number on it anywhere ?
On the TDA 5850, pin's 8 & 4 are inputs to the switch, pin 3 is the switch, and pin 2 is the output.

That is a good guess. I was going to suggest a VCR video record/capture card myself, but then, it'd prob'ly have audio in/outputs too. It might be a good idea to pop it into sum'n and dump the ROM, could be a klew there.

Google "Alpha Micro Videotrax" and read all about it.

I used a competing VHS backup system in the 80's. S L O W . . .

Was it the 'OmniNet' thinggy? I used to have a metric sh!tload of that stuff, but never got to use any of it because I didn't have any of the cables.

So that's what it is, Thanks for help,

Now we know what it is, anyone want it?

I'll take it--I can always use another oddball media adapter.

I think lmd wins...he has the appropriate hardware to go with it!

You can probably get software anyplace that carries home betamax tapes.

Drop a line to Sellam Ismali over at VintageTech--ISTR that he was fooling with one of these quite a while ago. Maybe he still has the software.

... guessing its one of those "backup to VCR" peripherals...

Bit of an old thread this one, but it's the closest match I could find that has some relevance to an "Autofax Corp Imager" 8 bit ISA card I recently picked up. It's a Z80 based "backup to VCR card".

7107 7108

The eprom is currently damaged (missing a couple of pins!), but I've soldered in place some wire and read its contents. I'll have a go at blowing a replacement. Interestingly, a dump of the eprom show the text "'MaBr[2.4] (C) 1983-Corvus Systems". I've partly disassembled the code.

Ideally, I'd like to get this thing working and see how well it backs up and restores files (not that I'd use it in vain!). So, does anyone have or know where I could get a copy of the software that accompanies it? Most of the references on the web for this are just adverts http://books.google.co.uk/books?id=0DsEAAAAMBAJ&pg=PA28&lpg=PA28&dq="autofax+corp"&source=bl&ots=IWX9cbT6KR&sig=5q4Ktq7jcOc3XRYwL6c4trHZlPU&hl=en&ei=hMbCTriFHMSv8QPwvOnnCg&sa=X&oi=book_result&ct=result&resnum=1&sqi=2&ved=0CC8Q6AEwAA#v=onepage&q&f=false

Edit: If the above link doesn't bring up the advert, click on the search button next to "autofax corp" and then click the link for "InfoWorld - Aug 24-31, 1987"
