Saitek Corona

This Saitek Corona is an auto-sensory chess computer with the Saitek ‘D+’ program of Julio Kaplan and Craig Barnes running at 6MHz, I think. The ROMs are dated 1991 and the box refers to the stronger later program, making it a Corona II, as it was called at the time. Its rating is therefore about 1950 Elo, and it has one of the strongest programs from the Kaplan/Barnes team.

This Corona is in full working order and in generally good condition as the photos show. However there are a couple of pieces of veneer missing from the sides and the non-original chesspiece set has one odd black pawn.

The item for sale includes the chess pieces, box, original manual and adaptor (Euro plug).

Fidelity USCF Special Edition 1 20 x 21

Fidelity USCF Special Edition

The USCF is a rare chess computer. It was made available in 1984 only to members of the United States Chess Federation in a limited edition. Supplied in a Champion Sensory Chess Challenger box it is distinguished from other similar Fidelity models by the distinctive black sticker, USCF Serial Number plate, built-in CB9 openings book and the Prestige 24K program running at 2.5MHz.

This example is in very good cosmetic condition and full working order. In the photo (below left) the USCF is indicating checkmate and showing all of it’s LED’s working. The box and polystrene tray are in only  moderate condition.

It comes with the original box and chess pieces, power adaptor (with Euro plug) and original manual all as shown in the photographs.

Splice Byte XD-300

The Splice Byte is a very rare Brazilian chess computer, a clone of the Fidelity Chess Challenger 7 (CC7). Probably the only chess computer model ever to be manufactured in Brazil.  They were made in 1982 and included a copy of the Ron Nelson CC7 program. The oo-oo display (bottom photo) revealing its origins.

This one is in original condition, fully working including the healthy beep that accompanies keypresses and moves, with some signs of wear  as shown in the photos. It comes with the box, original chesspieces and piece box, original manuals (in Portugese, a CC7 manual in English can be provided), and with a suitable adaptor (Euro plug).

An intriguing chess computer about which little seems to be known. All Russian in manufacture, this example comes with the four level program chess cartridge of apparently Russian origin (not the CC3 three level pirated program). Cartridges for other board games are available.

The Intellect-02 is very rarely found outside Russia. It has not been reported on as yet, nor tested against other machines of similar strength, as far as I know. You can read more about it here (link).

This Intellect-02 comes with the four level chess cartridge, cartridge box, plus the computer unit and cartridge manuals (in Russian). The power supply is integral and the Intellect-02 can be used with a shaver adaptor in the UK. I would expect it to work from Euro sockets. The cap which should go on the on/off switch is missing which has no effect on operation. The chess cartridges were not sold with chesspieces. Moves are by keypad entry so pieces with or without magnets can be used. The chessboard is metal.

SciSys Chess Partner 6000

The Chess Partner 6000 is surprisingly rare. Until 2008 there were no examples in  collections published on the internet, nor to my knowledge had anyone in the chess computer community actually seen one. You can read more about it in an article by chess computer historian Hein Veldhuis (link).

Like the other SciSys Chess Partners, the Chess Partner 6000 is a simple machine of very limited strength and features intended for the mass market. It boasts only four levels of play and a press sensory board. In common with several other SciSys models it uses a Hitachi HD44801 4 bit singlechip running at 0.4 MHz  with 2KB of program ROM and  64 bytes of RAM and Mark Taylor’s (+David Levy) 4 bit chess program.

The Chess Partner 6000 for sale is in good fully working condition. It comes with the box, chess pieces and copy manual  and uses 3 x AA batteries (not included).

This one comes with the set of chesspieces shown and copies of the English and German manuals. It works well with either an adaptor or 6 x AA batteries (not supplied), although the battery compartment has a little corrosion.

SciSys Executive Chess 2a 20 x 20


Square Off Kingdom Set

Square Off is a Kickstarter crowd funded project developed in India. The result is this ‘telerobotic’ board which works via a phone app. The moves are received from the opponent or from the incorporated chess program and  transmitted via bluetooth to the board which has a similar robot mechanism to the Milton Bradley Grandmaster or Fidelity Phantom etc. This plays the opponents moves on the board automatically, and receives your own moves using the press sensory surface for transmission back to the opponent. So you can play chess with someone across the world by phone, or via or you can play against the chess program, all automatically using the robot mechanism. The chess program is a 20 level much cut down version of Stockish with a minimum of functionality at present. Nevertheless it is still very playable on the higher levels. Development continues. The board, pieces and packaging are of a high standard as you can see in the photos.

The item for sale consists of one Kingdom Set including all accessories (chesspieces, adaptor, boxes, instructions) all as
new. The app is available free to download from app stores for iOS or Android.
