- title: COMPLETE UNIT
subtitle: ''
text: |-
The memory unit was available in two versions : the complete Adam memory unit and the Expansion Module #3. This expansion module was meant for people already owning a Colecovision system. So part of the hardware is not in the module but in the Colecovision... In fact the Expansion module #3 uses the hardware of the Colecovision system !
The unit pictured here is the complete memory unit. We recognize it by its cartridge slot, necessary as there is no Colecovision system attached to this configuration. In fact the Colecovision system is literally built-in this complete unit.

When presented for the first time at the Chicago's Consumer Electronics Show in june 83, the Adam looked like this...
It's nearly identical to the final project, except for the digital tape drives which look more like the Exatron stringy-floppies than the digital data-packs finally adopted... Here the tapes seem to be loaded horizontaly into the drives.

This is the expansion module #3, aimed for the people who already have a Colecovision system. Without the Colecovision, this version of Adam can't work ! It needs the hardware of the Colecovision.
The system looks like the complete version but its right part is shorter and there's no cartridge slot as the Colecovision provides one. The Colecovision plugs at the back of the main unit as shown on this picture.

This is the complete configuration of the expansion module #3, except that there's normaly the Colecovision system attached to the back of the Adam unit...
The black controller comes from the Colecovision and no "white" Adam specific controllers are sold with the Expansion Module #3, as the Colecovision provides already two of these...

A beautiful french woman using the built-in wordprocessor software of the Adam (expansion module #3 version).
In some countries, like in France for example, only the Expansion module #3 was available. Thus people wanting to buy an Adam, HAD to buy a Colecovision if they hadn't already one... This didn't help the sales at all !

- title: PRINTER
subtitle: ''
text: |-
ADAM technical says :
*The printer is a letter-quality, bi-directional, daisy wheel printer. Paper feeds into the printer through a friction-feed mechanism that accommodates single sheets of paper up to 9-1/2 inches wide. With the addition of an optional tractor-feed mechanism, the printer also accommodates continuous, "fan-fold" paper. Pitch is 10 characters to the inch, and printing speed is 10 characters per second. The printer contains two printed circuit boards, one for the printer and one for the power supply.*
*The printer houses two printed circuit boards: the Printer Board and the Linear Power Supply Board. The Printer Board includes a 6801 microcomputer and parallel drivers that control the printer's electro-mechanical devices. The electro-mechanical devices include the daisy wheel motor, the carriage motor, the platen advance mechanism, the print solenoid, and the ribbon solenoid. The Linear Power Supply Board includes regulators, rectifiers, and a transformer.*
*The printer 6801 communicates with the Master 6801 on the Memory and I/O Board via AdamNet to receive data to be printed, controls the motions of the printer's mechanical parts, and ensures that the printer performs the optimum number of motions simultaneously.*
*Within the printer 6801 RAM is a 16-character buffer for data being sent to the printer over AdamNet. The buffer ensures that time is not lost between characters being printed, and maximizes printing speed.*
*The printer 6801 responds to some ASCII control codes, including carriage return, line feed, backspace, escape, shift-out, and shift-in. Shift-out causes the printer 6801 to reverse its left and right directions, allowing printing from right to left.*
*The printer 6801 controls the printer's electro-mechanical devices. It also ensures that lateral carriage motion, rotation of the daisy wheel, and stepping of the platen can be activated simultaneously.*

This is the expansion module #3. This Adam model can not work without the Colecovision game system.
**(1)** The separate keyboard is undoubtly an advantage very few home computers offered. It is complete and of good quality. The 6 function keys have their actions re-defined for each software used (with the built-in wordprocessor for example).\
**(2)** The joystick attached to the right of the keyboard is also a good idea. The control stick is small but efficient with all games.\
**(3)** The standard joystick offers two shooting buttons (same function).\
**(4)** The joystick's keys act as a numeric keypad and can be used in every Adam software.\
**(5)** This plastic part helps to make the joystick a true keyboard extension.\
**(6)** Reset button used to reboot the complete system (console + computer).\
**(7)** Connecting the ColecoVision console with the Adam computer does not prevent from playing with the great choice of available game cartridges.\
**(8)** This expansion port is used to connect the ColecoVision game system and the Adam computer.\
**(9)** Keyboard connector.\
**(10)** Housing for an optional second tape unit. The standard version of the Adam version is sold with only one tape unit.\
**(11)** It looks like a standard cassette, but is a specially preformatted, thus costing much more... This means that standard cassettes can't be used.\
**(12)** This is a smart tape recorder, much faster than a normal one and completely controled by the system for file management.\
**(13)** Connector for the Adam printer which also provides power supply. Thus, the printer must always be turned on, even if it is not used.\
**(14)** The Colecovision is fixed to the Adam through a fragile plastic plate. It is not recommended to move the whole unit too often.\
**(15)** Some logical functions of the ColecoVision console are used by the Adam module which hold the Z80 microprocessor and the memory.\
**(16)** Joysticks housing.

- title: 3.25'' DISK-DRIVE
subtitle: ''
text: |-
Yes, it's really a **3.25"** disk drive with 3.25" diskettes, a new format created by Dysan to replace the 5.25" format. Sadly, this format never became a standard and was quickly forgotten.
About this prototype, **Doug Rosenvinge** says:
My drive is a working prototype and not a production unit.\
The drive case replaces the memory console cover. The drive connects to the Adamnet port and uses a 3 pin power supply of the type used for some of Coleco's accessories. I have also seen a version of the drive that fits in the memory console itself in the larger bay in place of a tape drive. That version uses the same plugs as the tape drive for its signal and power.
The reason this drive is so large is that it's logic board is wire-wrapped and is next to the drive in the case.
Of interest is the way the disk is inserted. It slides in onto a built in tray that can be pushed in and locked in place by pushing down lightly on the tray. The total movement is about 1/2". To take the disk out just push the tray in and up and out pops the disk. Rather neat.
Off hand I can't remember the full storage capacity, but it was compatible with the tape drive although I think you could reset the capacity in the directory and get a couple more blocks of storage. Of course if you did store more than it would not be 100% the same as a tape.

The ADAM is available in two models, the complete system and Expansion Module #3. When the memory console of Expansion Module #3 is connected to the ColecoVision, the two models are essentially identical in function. The unit pictured here is the expasion module #3 (it is shorter than the complete unit). The expansion module #3 uses part of the Colecovision hardware, thus the memory unit doesn't have any cartridge slot, and isn't delivered with any controllers nor TV switch box.
The whole system is made of the daisywheel printer, the memory unit and the keyboard. The power supply is built-in the printer!
The Smart Basic isn't in ROM and has to be loaded from a tape, however there's a little word processor in ROM, this word processor prints the text to the printer at the same time the user types on the keyboard, but can also be used as a classic wordprocessor.
The Adam had a pretty short life, only two years! Despite this there is still a community of Adam fans who still use their system. Nowadays, most Adam users use a 320k 5 1/4 inch disk drive, an external 2400 baud modem, and a 20, 30 or 40 megabyte IDE harddisk. Adams often have memory expanders up to 2 MB in size (which is usually used as a RAM disk), and also a parallel printer (like a bubble jet)!
Greg Bowman reports that he got an external CD drive for his Adam from his uncle who was then Vice President of Coleco. He notices that this CD drive was designed especially for the Adam. If anyone has more information about this CD drive, don't hesitate to mail us.
