For European ADAMs, Coleco provided "language cards" which had French or German versions of the SmartWriter ROM word processor, including alternate graphics character sets for use with corresponding daisy wheels for the ADAM printer. Three electrical signals necessary to access these language cards are not implemented on ADAMs built for North America.

Factory Test Harness

The EXPAnDDR board adds a BOOT PROM socket, a parallel port, and a memory expansion board addressor port to your ADAM computer.

This is a cost-reduced design for users who want to experiment with available BOOT PROMs, diagnose a faulty ADAM computer, use a parallel printer, or need a cheap memory addressor for expanded memory.

More information on the EXPAnDDR board as well as boot PROM images can be found at Eric Pearson's GitHub project page at https://github.com/epearsoe/EXPAnDDR.

REQUIRES ADDRESSOR BOARD (MIB3, MIB238, WXPAnDDR)

The Lundy Electronics Coleco ADAM RAM Expander Signal and Expansion ROM board is a Lundy Electronics exclusive design, an economical way to generate the required memory expander "addressor" signal for memory expanders over 64K. It is also a great way to use expansion ROMs such as auto-booting to SmartBASIC, ADAM diagnostics for testing/repairs, or other expansion ROMs available from other sources. Lundy Electronics offers expansion ROMs at time of purchase for an additional cost on all their center slot expansion board offerings.

Coleco ADAM Expansion Board – The Coleco ADAM Multipurpose Interface Board. Although Eric Pearson's MIB238 GitHub project page documents how to make one, Lundy Electronics offers these cards for those who don't have the skills to build their own. They are fairly expensive to create because of build and test times and time to source obsolete and specialty parts. The MIB238-LE1 board does not have the built-in WiFi modem like the MIB238-WiFi version we offer and is for users with a physical modem or other external WiFi modem such as the popular WiModem232. The MIB238-LE1 is a Lundy Electronics custom spin-off of Eric Pearson's original MIB238 design with the following changes/additions.

The Lundy Electronics ADAM Delta DRAM to SRAM Converter PCB mod uses modern, readily available components to replace original, obsolete DRAM. The added benefit of this mod is that it also removes the inefficient need of +12v and -5v required by the original DRAM. All the original DRAM, associated decoupling capacitors, and power inductors are completely removed from the system. The new SRAM Conversion PCB then installs where the original DRAM was located, and specific required pins are then soldered in place on the PCB.

We now have the ability to create new tapes with true digital formatting for the Coleco ADAM! You will no longer have to hunt down and spend a ton of money trying to procure a seemingly impossible to find MEGACOPY III by Trisyd back from 1987.

Note: You need two DDP drives in working order to use this device.

Features:

• Small 1-7/8"x1-7/8" PCB that adheres to the inside wall of the console just to the right of where the DDP connectors go that stays totally hidden from view.
• The status LEDs and button are placed at the top for easy access.
• Improved design by using a small 8-pin PIC microcontroller to handle the control logic in place of the discrete logic the original design had.
• Simple, low-cost momentary button enables/disables the device in place of the expensive SPST push (not toggle) switch of the original and also controls both status LEDs.

The Lundy Electronics Coleco ADAM 1MB RAM Expander Board is a Lundy Electronics exclusive design. It uses low-cost, currently-active components from major USA parts suppliers. The design only requires two ICs and passes the saving onto the buyer to make it the lowest cost 1MB RAM expander ever made for the Coleco ADAM.

Like all ADAM RAM expanders, it requires an additional "memory addressor" signal not available on the third slot where the 1MB RAM Expander is placed to break the 64K expansion size barrier. This signal can be obtained from one of three additional Lundy Electronics center-slot expansion board options.

Note: This expansion board gets installed in the third (right-most) internal ADAM expansion slot. It is designed in such a way to prevent it from being inserted backwards but also has a silk screened front with arrow direction on the backside of the PCB for additional reference.

The Lundy Electronics Coleco ADAM 2MB RAM Expander Board is a Lundy Electronics exclusive design. It uses low-cost, currently-active components from major USA parts suppliers.

The Coleco ADAM ADAMnet Power Inlet Board for External Power Supply Adapter is a Lundy Electronics exclusive that offers a seamless way to add an internal ADAMnet connector and a printer reset silencer while using a factory printer power supply. Limit two per customer.

Features:

• Fully backwards compatible replacement for factory Coleco power inlet board and mounting
• Quality DB-9 power inlet connector positioned slightly more forward than factory Coleco power inlet board for better connections using third-party external power supplies
• Internal ADAMnet connector for internal expansions, such as the Lundy Electronics Internal ADE Pro and Internal FujiNet
• ADAMnet reset silence jumper for the ability to stop printer reset every time the ADAM reset button is pulled.

Mr. Pearson's Multi-Interface Board 238. To be clear we did NOT design them, we only build them for you to use. As described on the GitHub Website:

The Multipurpose Interface Board (MIB238 board) is a redesign of the Micro Innovations MIB3 board that only requires 5 volts using modern MAX238 transceivers. The MIB238, like the MIB3, adds a BOOT PROM socket, two RS-232 ports, a parallel port, and a memory expansion board addressor port to your ADAM computer.

We have made them in the following varieties:

MIB238 version 5: Gives you everything as described above.

MIB238 version 7: Gives you everything as described above AND a WiFi adaptor. It is programmed with Modem software.

You also may choose to add on a BOOT EPROM
