I think that this is an easier to understand version of the endgame tablebases.

Chessmaster, The (NES) - Online Game | OldGameShelf.com
From 1984 to mid-1990's I owned 3 chess-playing computers. I sold them when I switched over to desktop computers, but I kind of regret not having them any more. Part of me wonders if they would still beat me today like they did back then? I am wondering if I could now give them a better game?
The 1984 Novag Super Constellation was pretty impressive considering that it was running on just a 4 MhZ 6502 8-bit processor. The USCF assigned it a rating of 2000, which is likely a little high. It is my understanding that the program only looked at 500 moves per second Compare that to my 64 bit 3.4 GHZ iMac with 4 cores. Stockfish on this computer looks at around 5 million moves per second.
Nevertheless, I had trouble beating the Super Constellation at level 1 which was 5 seconds per move. At the time, I was rated in the 1700's. I could win most of the time, but the higher levels game me trouble.
I am surprised to find my name on a webpage about the Super Constellation. https://www.chessprogramming.org/Super_Constellation Apparently in 1998 I made a forum post where I was wondering the exact same things that I am wondering now. Even then I referred to this as an old chess computer.
The 1988 Fidelity Designer 2100 (http://www.spacious-mind.com/html/designer_2100.html) series running an 8-bit 6502 at 5 MHZ was a slight improvement over the Super Constellation. The USCF gave it a rating of 2100 which some claim is too high. I certainly found it a challenge, but I wasn't content to stop there. Later got the 16-bit Fidelity Designer Mach III 2265. For its time, this thing was a beast. I played it a ton of games at G/30 and only won once. At the time I was rated 1800.
I can't go back play these old chess computers, but I can run some older videogame software through emulation.
I found a website that runs The Chessmaster program from 19991 for the Nintendo Entertainment System. This is emulating a 1.79 MHZ 8 bit 6502 processor. This should be a little weaker than the Novag Super Constellation.
First of all, I am surprised that a website can emulate an old videogame system. I also found this fun to play. The controls take a little getting used to. You have to press "Select" (shift key) to get to the options where you can control the difficulty. There is also an option to make it full screen. The graphics aren't the best, but are okay.
As as I said, I found this fun to play. There are a couple of beginner levels, and then level 1, 2, 3 etc. After beating level 1 at 5 seconds per move, I only barely beat level 2 at 7.5 seconds per move. I had to outsmart it in the endgame to win.
I am able to run the SNES version of this program through emulation on my NES Classic videogame system and on the PC. The SNES 65816 processor is twice as fast and a little more sophisticated, so the SNES version should be as good as the Novag Super Constellation. At the time that these Chess Master programs were released for the videogame consoles, which was around 1991, the version of Chess Master for computers was called Chess Master 2100. I later owned a copy of Chess Master 3000 which seems extremely crude now.
In the 1990's I programmed SNES videogames for a living.

This Happens To All of Us || Morphy vs Löwenthal (1858)
I find the endgame interesting. There is also a very interesting pawn sacrifice by Morphy that his opponent wisely doesn't accept.

chess.com changes to their rating system today
Earlier today I noticed that my chess.com bullet rating was 1900. This could not be correct, and later it showed up as 1649. However, my bullet rating had been at a record low of 1499. Chess.com decided to add 150 points to all bullet ratings to make the average match the average of their blitz ratings. I still think that their ratings are too low, but this is a welcome improvement.
Prior to the adjustment, my highest bullet rating was over 1700.
In addition, chess.com has decided to start counting G/10 as Rapid instead of Blitz. This would have affected how some of the games I played tonight were rated. I thought that the USCF considered G/10 to be Quick and not Blitz, but I was wrong. It appears that the USCF considers G/10 to be Blitz and maybe Quick as well, although I personally think that Blitz should be considered less than 10 minutes.
Chess.com considers anything longer than 9 minutes to be "Rapid", except for "turn based" postal like games.
From what I can tell, the USCF considers 10 to 29 minutes to be "Quick". Anything from 30 to 59 minutes was traditionally called "Action Chess", although the USCF now rates 30 to 60 minutes as dual rated both Quick and Regular. The USCF considers anything over 59 minutes as "Regular."
