I like to hear from you, and
This red Donkey Kong was originally a Radar Scope. (Fort Gibson, Oklahoma, USA)
The owner restored this machine and had to repair its original monitor chassis (tube and chassis see video page)
Upright restoration project by Dan, Hammond, Indiana, USA:
"... it was converted to some Jamma game, most likely Smash TV. The only
thing that remains of Radar Scope was the wiring harness and half of the power
supply. Other than the terrible t-molding, It’s in pretty good shape.
I plan on restoring this guy to his former glory…"
"... CamaroMurph from KLOV thinks it may be the earliest Radar Scope Cabinet
ever: Serial Number: A01019 (19th ever made?) Coin Counter: 007216..."
Rare cockpit version restoration project by Jim Z, USA:
"... so far there is not anyone else that has a r.s. cockpit [in his area].
ive attached some pics of the game as it looked when i bought it. ive been repairing
wood and holes, then repainting the whole cabinet..."
Upright Radar Scope contributed by Mike M., Naperville, IL, USA:
"Just purchased my first Radar Scope game. It is an upright. Interesting
tag info. I have attached a picture of the tag"
"Serial number B02943.
Pretty high serial number considering all info to date suggests that there were none over B018XX. It also does not have the monitor in a box like all the others I have seen. It has 2 carriage bolts through the side similar to my red DK."
"I have been trying to put together a serial number list of Radar Scope and DK cabinets to put some sense to when all the different transitions happened. It is on KLOV in the general section under "Call for DK and Radar Scope tag/cabinet data". I have about 5 or 6 Radar Scope games in the list. A couple of UK games and the rest US. Nothing over B018XX until now"
Contributed by "Level42", Ridderkerk, The Netherlands (Jun, 2008):
"It was half-converted to Mario Bros. when I bought it, but the monitor
was still in vertical position and has a light Radar Scope burn-in. I am completing
the conversion to MB for now, because all the artwork is there already and in
very nice condition"
"...This cab was a UK cab, you can see that on the plate. It was also configured for 240 VAC and had a UK plug when I got it. The seller told me that indeed it
came from the UK originally.
I already have an original MB PCB set (unknown if it's working) and there's a MB wiring harness on it's way to me from the US."
A lot of pictures and more info on this conversion project by Level42
can be found here in the ArcadeControls
|This is the (somewhat scratched) serial plate which reads "TRS HL A 03677"|
The following scores story was sent to me by 'ks' in June 2008:
"Lately, I've been thinking back over my teen video-game exploits, thinking
I might hunt down &
play some old favorites -- maybe even try to crack some old scores. Looking around on the Net, I
was a little surprised by the "official" high scores, because none of them are close to what my
high school friend & I were putting up. Back in 1981-2 we were pushing each other pretty hard --
together we had at least a dozen scores over 135,000. My friend had broken 150 -- the high score
between us -- but I held 2nd, 3rd, & 4th. That machine was so beat up lol! The knob broke off, so
we wrapped the joystick with electrical tape. After that, the fire button fell out & disappeared, but
we discovered you could still play by sticking your finger down in the button hole. Not long after
that, I played my final game...
... I was on a really good run -- I had a lot of points early -- when a maintenance
guy of some kind
started leaning in and trying to get around behind the machine while I was still playing. Then he
came back with a dolly cart and started to wiggle it under the machine, & I was thinking wtf! Finally
the arcade owner shows up & says that the machine is shipping out, and the truck is in the lot &
ready to go. I'm having this great game, poking my finger down the little hole, & they're rocking
the machine like I'm not even there lol! Lucky for me, the owner kind of knew me, and he caved in
to my begging and let me finish my game. It must've been like half an hour before I finally got
crushed at... 153k+. I remember making everybody wait as I filled in the whole row with my name.
Oh, that feeling of utter futility has never left me!" (ks)

|This is a serial plate of possibly one of the last radarscope uprights to be produced, which reads "TRS UP US B 01874". Here is a picture (263 K) of this machine standing next to one of the first "red" donkey kongs to be made. (both pictures shown by permission of Rory Blake, North Carolina, USA). According to this source, the Radar Scope production amounted to something like 800 units (where serial numbers started at 01001) and the later Donkey Kong production to 75,000 units. DK was designed to use the Radar Scope base hardware, including the red cabinets (making about 1200 "rare red cabinet" Donkey Kongs).|
|This is a Donkey Kong cocktail table in the exact same cabinet type the Radar Scopes were put in. Here is a picture (189 K) of this machine with the top open. Except for the slightly larger monitor frame the design is not different from the Radar Scope cabinet insides. (both pictures shown by permission of Ed Mandy, Minnesota, USA).|
