Contents of the Epyx development kit
The Epyx development kit for Handy consists of a number of items ranging from hardware to reference materials and software:
Mandy and Pinky
Mandy is a slightly modified, fully functional Lynx I that has the Reset and NMI pins connected and has a special “cartridge”. The cartridge is essentially a connector to Pinky. Pinky is a custom electronics board that sits between the Commodore Amiga and Mandy to facilitate the communication and optionally hold ROM images of your Lynx programs. It has two buttons to trigger the reset and NMI signal to Mandy.
These pictures are from my own development kit. In clockwise order starting at the top left they show
- Pinky and Mandy with a blue parallel cable and the special cable to Mandy
- Special cartridge in Mandy holding the cable
- Inside of Pinky
- Outside of Pinky with the blue parallel cable and two buttons (Reset and NMI).
Howard and Howdy
This hardware set was more expensive than Pinky and Mandy, but offered some extra functionality. The set has two pieces of hardware called Howard and Howdy. Where Mandy is a full Lynx, Howdy has no processor and memory of its own. Instead, the guts of the Lynx exists in Howard, a PC case with a huge motherboard.
It holds the 65SC02 processor and lots of RAM and additional logic to offer functionality for bus monitoring and tracing of your code. Howard is connected to Howdy for display, sound and input. In turn, the Amiga is connected to Howard. The last two pictures (from this thread at the AtariAge forums) show the Howdy console connected to Howard.
The Epyx kit did not include the Commodore Amiga 2000 that was needed. You could have any Amiga machine, but the 2000 model was recommended because of its harddisk and memory.
A binder full with hundreds of pages detailing the internals of the Handy hardware, the use of the Amiga software and Epyx SDK for developing Lynx programs. When updates to the SDK were made, addendums where issued that you could place in the binder.
The software accompanying the the development kit is provided on a set of 8 disks that contain the Amiga software, source code and samples you need to develop Lynx programs.
The SDK’s 3.5″ floppy disks restore a Quarterback backup set to the system partition. You needed to have Quarterback software to use the disk. This is the way it works for the 1.6 revision of the SDK. Older sets may have worked in a different way. The backup sets were created using QB 4.2, but version 5.0 is also capable of restoring the set. The restore would add custom files for the Workbench 1.3 operating system under C2, replace some its system files in the C folder and place the SDK tools and source code (actual sources, include files, macros and sample code) in two folders called 6502 and HANDY.
The development software contained the compiler, sound and rom creation tools, and the source code for building Lynx programs. Additionally it had Amiga tools that made working with the Amiga as a development machine a little easier (e.g. faster fonts and a better text editor).
