Hello All,
I'm interested in any information anyone has about the Fidelity Impact Printer, specifically how it interfaces to, for example, the Fidelity Sensory 12B Chess Challenger.  I have the 12B, but no printer, but I'm wondering if I can create some sort of circuit (I'm an elec. engr.) that would allow me to capture the printer output with a computer.  I'm thinking this should be fairly easy if this is a serial printer interface, but since I don't have any information about it I'm lost.  If someone knows something, please reply.  Thanks!!

The voltage is AC, with a transformer rated at 9 volt, 18 watts, 1.5 amps should be fine for your unit. There are a couple on Ebay right now # 110432466449. The impact printer may actually work better on a well regulated DC supply too, as mine would sometimes print garbage after turning on. I fixed the problem by making a filtered DC supply by using the original Fidelity adaptor, feeding the 9 VAC into a full wave rectifier, and hooking the output of the rectifier into 40,000 uf computer grade capacitors. I then feed the DC into the power cord pigtail for the printer. Doesn't look pretty, but my printer turns on reliably now.

Funny thing is, I think Fidelity knew of the problem. They put a big orange sticker saying to plug the printer in and wait 3 seconds to switch the unit on. Must be that 3 seconds is so the power supply can charge the small internal capacitor in the printer. My opinion is that cap is not big enough.

Hi,  regarding impact printer.  I bought one but the power supply cable is cut (no adapter).  Can you tell me the voltage and whether DC or AC.  Plus mine is for a vic 20 and has an extra center pin on the plug.  I wonder if it will work with my challenger 12 or voice sensory should I pull the pin?  Can you check yours for me on the voltage?  Mine may not even turn on but I did order ribbons per your advice.  Many thanks...

Very cool info Mike! Thanks for sharing!
I still hope to be able to hook up a printer to a chess computer one day. Just for the fun of it

Hi All

A while back I bought a Fidelity Impact Printer from eBay which was claimed to be fully working but producing very faint printouts. This I put down to the ribbon ink drying out. Looking at it closely for the first time the other day I discovered that there was actually no ribbon cassette in the printer at all ! 

So I started looking for a source of ribbons thinking that it would not be too easy with a 25 year old printer sold in relatively small amounts. 

Anyway one of the numbers on the printer mechanism says M-160, and it turns out that this is the same number as for an Epson mini-printer. It also happens that ribbon cassettes for the Epson are still readily obtainable so I ordered some hoping that they would fit.

Well they do fit. The Impact Printer nows works perfectly and I can keep the moves of my finest victories against Fidelitys for posterity. Should I ever get one again I'll post it here. 

The ribbon cassettes are available for as much as 10 each in some places, but there is a current eBay source with 5 for 5.    If you are interested the part number is ERC-09.

All the best
Mike
