Back around August of 1982 I owned my very first ColecoVision videogame system for around $200. Sometime in 1983 or 1984 I purchased Expansion Module #1 the Atari 2600 adapter with a list price of around $60. This adapter is 100% compatible with Atari 2600 games. However after I started collecting Atari 2600 game cartridges, I discovered that the adapter was only really 99% compatible with Atari 2600 games unless one also owed the Coleco Cartridge Extender (Official Coleco catalog part number 592114).I found out that the Starpath Supercharger would not work on the Atari 2600 adapter because the physical plastic case of the Starpath was different compared to your average Atari 2600 cartridge case. Therefore I called Coleco’s toll free number back in December 1984 or early January 1985. Coleco informed me that I needed a Cartridge Extender that has a value of $30, and they would send one to me for free. I had to give them my serial number and address over the phone so they could verify that I had Expansion module #1 the Atari 2600 adapter. When I received the Cartridge Extender in January 1985 I now could play 100% of Atari 2600 cartridges including the Starpath Supercharger. Later on that month or a few months later I purchased a second Expansion Module #1 Atari 2600 adapter. However when I called Coleco’s toll free number I was informed that even though I own two Expansion module #1’s, the Coleco policy was that they only offer one Cartridge Extender per address. Therefore, I was not able to get a second Cartridge Extender. These Cartridge Extender's are extremely rare, and since it was a $30 value, Coleco only sent out one to customers who complained about the problem of not being able to play some products like the Starpath Supercharger. Coleco stopped making videogames back in 1985. Sometimes I wonder why Coleco did not redesign the plastic case for Expansion Module #1 so that they would not need to make Cartridge Extenders. Maybe Coleco might have re-released Expansion Module #1 with a built in Cartridge Extender if they would have continued to make videogame products instead of the business decision to stop making videogames and computer products in 1985.


The following website has a detailed picture of the Cartridge Extender (It is too bad someone does not reproduce this product and sell it for $30. There are ColecoVision owners that would like to have one of these to use with their existing Expansion Module #1 Atari 2600 adapter :

Attached are official Coleco documents from 1985 in regards to the Expansion module #1 Cartridge Extender with a Official Coleco catalog part number 592114. I also snapped some pictures of my personal one and only Cartridge Extender.

I wish I had known about the extender as I kid before I used to a file to widen the opening of the expansion module.
