ColecoVision & ADAM Computer Forum

IS there any updated thoughts out there as to what the ADAM Final Test Module" Does?

It was initially un defined by those that acquired the 2 units on eBay a few years back.

Then the latest thouts in 2010 were:
Jr. (of Colecovisionzone.com) has one of these ADAM proto module and came to my house 2 hours ago with the ADAM proto #6
which the pictures you see in the first post by retroillucid.

First, Jr. discussed this at the last CCJVQ meeting with me and Daniel (newcoleco) and newcoleco said that he thinks that is a Tape Simulator.
Well, Newcoleco huch was right! It is a Tape Simulator module.
The RS-232 connector is for transfering Super Games in it and to test them on a ordinary Colecovision.
The ADAMlink connector is to connect a keyboard so you can play any Super Games.

There is an Eprom with the sticker "TapeSim" on it, which I deduct that is a modified BIOS or not-modified BIOS of the ADAM.
But before I can dump the content of the EPROM, i need some informations that are not found on the net.
The EPROM is a Motorola SC88091L / CD48337 and the VPP = 22-24Volts.
If anyone has infos on the SC88091L, please let me know so i can dump properly the content of the EPROM.

For now, these are all speculations until we're able to dump the EPROM, just hoping that nothing is erased in it.

The Coleco ADAM Museum has acquired a unit with all attachments and cables.

We will be studying it and releasing more information in the near future

The Module and a assortment of documentation and schematics has arrived!!!!!!


Much more to come

This internal guide explains each of the Test Units, Hardware needed and Software to support each test.

The C-Clamp thing is wild!

The poor thing was not stored properly. I hope the internals look better than the outside.

Ill send it to you for service & repair

Haha. It sure looks confusing and fragile.
