Ritam Master Monty Plays Scrabble (Monty Conversion) (1987,
LCD, 4 C Batteries, Model# ??)
CPU: Z-80 Microprocessor
Programmed by: Robert Walls (according to the Main System ROM)
Extra downloads: ROM images of Master Monty Main System ROM (27C256 EPROM)
Expansion Module #1 / Expansion Module #2 (Both 27128 EPROMS)
Ritam's second-generation Scrabble computer that allows you play a game of Scrabble by yourself (or you can play with up to 3 players). Has a built-in 24,000 vocabulary (double the built-in capacity of the previous version), which is expandable to 56,000 by way of 2 expansion modules each containing 16,000 more obscure words (the modules are the same for either Monty or Master Monty), and has a more advanced Scrabble program for more complex (and difficult) gameplay. You can use the included 'score cards' (which look like little Scrabble boards), or you can use a real Scrabble board and tiles to play. The ROM images of the System ROM and both expansion modules are available above for download. You can burn them to the appropriate EPROM and install them in your game (but you still need the plastic adapter for the expansion modules unless you want to replace the sockets with normal chip sockets or solder the EPROMs directly to the main board). The links go directly to the binary files, so you might have to do a right-click/save-as. (Also note, Monty and Master Monty apparently originally came with a little pen, which you can see in the first picture.)
Master Monty was available in two forms: one is a direct conversion of an existing Monty (so it looks the same from the outside) as seen here, the other had a blue colored case manufactured for it to make it look different. Both of these versions are hand-upgraded by adding chips and wires to the inside of the game (this is why I've included circuit board pictures here so you can see the difference).
Same Monty image as the regular Monty, but notice the the box
has a little white sticker on it that says 'Master Monty'.
Here's the battery compartment of this game with one module installed
(this module doesn't have the red stickers of the ones in my Monty)
Here you can see the hand-made modifications to the board. It's hard to see, but just below
the Main System ROM there's a chip that's been added by gluing it upside-down to the circuit
board, and then soldering all the yellow wires to it's leads. Again, the 5 large chips/sockets are:
Z80 CPU / 2K Static RAM / Main System ROM / ROM socket #1 & #2 for expansion modules.
The Main System ROM for Master Monty is actually a 27C256 EPROM.
Do I have this? Yes, boxed.
