HP-71B COMPENDIUM (Part 3 of 4) [2020-08-31]
Card Reader Memory Modules ![[Image: CMT-CR-96R.jpg]](https://www.hhcworld.com/files/HP71COMPENDIUM/IMG/CMT-CR-96R.jpg) CMT Memory Modules Introduction Starting in 1987, CMT introduced several card reader memory modules for the HP-71B.
The following models was made available:
When plugged into the card reader port of the HP-71, the CMT-CR Module add the module specified kilobytes of RAM to the 17.5K bytes of HP-71 internal RAM. Up to 160K bytes of extra RAM can be thus installed in your HP-71. Like the HP-71 RAM, the CMT-CR RAM can be used as Main RAM or Independent RAM.
From the pictures below, we can clearly see that CMT decided to reuse their 32KB RAM front port printed circuit boards (PCB) soldered on a custom made PCB to create their RAM card reader modules. Also, some models had battery backup to preserve their data when unplugged.

HHP Memory Modules Introduction Somewhere in 1984 HHP introduced several card reader memory modules for the HP-71B.
The following models was made available:
When plugged into the card reader port of the HP-71, the HHP 71 M/M RAM module add the module specified kilobytes of RAM to the 17.5K bytes of HP-71 internal RAM. Up to 96K bytes of extra RAM can be thus installed in your HP-71. Like the HP-71 RAM, the HHP 71 M/M RAM can be used as Main RAM or Independent RAM.
For the RAM/EPROM & EPROM card reader modules, only the socket is present for the EPROM side, the user must insert his pre-programmed 8KB, 16KB or 32KB EPROM chip into the socket. Supported EPROMs are Intel compatible CMOS 2764, 27128, 27256 chips with 200 nanoseconds or faster of access time.
All HHP 71 M/M modules are build with the same internal components. The RAM modules are build with one, two or three PCBs which contain the following part:
The EPROM and RAM/EPROM modules are build with at least one module EPROM PCB which contain the following part:

FRAM71 Memory Module ![[Image: FRAM71_INT2.jpg]](https://www.hhcworld.com/files/HP71COMPENDIUM/IMG/FRAM71_INT2.jpg) Introduction The FRAM71 module is the result of a personal multi-years project of Hans Brueggemann. The module can be configured to add core RAM, independent RAM (IRAM) or ROM simulation. This module pushes the HP-71B to its limit and is a must have for any HP-71B fan.
Users' Manual Introduction FRAM71 is an FRAM memory extension for use in your Hewlett-Packard HP-71B Pocket Computer. When plugged into the Card Reader Port, it will provide your HP-71B with up to 16 additional RAM modules of user selectable sizes and 64 KB of system RAM.
With FRAM71, you can:
A special mention should go to Dave Frederickson and to Robert Prosperi for the countless hours they spent experimenting, trying things, documenting and helping others using their FRAM71 module.

Owner Manual Introduction The CMT-71 EPROM Modules come in two versions:
Up to four CMT-71 EPROM Modules may be inserted into the front ports of the HP-71. The CMT-71-32KE is organized as one 32K byte block of memory, while the CMT-71-64KE is organized as one 64K byte block of memory. Typically, the CMT-71 EPROM Modules are used to store custom application programs. You can run programs stored in these modules as well as read data from them. The CMT-71 EPROM Modules retain their contents when removed form the HP-71.
To see the amount of external EPROM provided by your CMT-71 EPROM Module, follow the instructions given in Section 1 to plug the module into a front port of the HP-71, then execute SHOW PORT. The port number, the memory capacity in bytes and the memory type will be displayed for each port containing Independent RAM or plug-in ROM. The CMT-71 EPROM has a memory type of "2".
Inserting a blank CMT-71 EPROM Module into the HP-71 will not disrupt its operations.

The programmer contains 64K bytes of CMOS RAM that is used to store the image that will be programmed into the EPROM modules.
The programmer connects to the HP-71 through a front port. The programmer's RAM is accessible through the commands in the HP-71. To use the programmer in the 64K mode, a FORTH/ASSM ROM needs to be inserted into another HP-71 port.
Additional software to help build the EPROM image is supplied on the CMT-71 EPROMs along with self-test programs. The EPROMs will need to be erased with ultraviolet light before programming. It is therefore highly recommended that you store these programs and functions on another mass storage medium so they will be available for use when needed.
This manual contains the instructions necessary for operating the CMT-71-P01 programmer.
Generally, you will not have to understand the internal operation of the HP-71 operating system to create custom EPROMs. If you would like to know more about the HP-71 operating system and its file structures, consult the HP-71 software IDS published by HP.
The programmer can be inserted into ports 2, 3, or 4. The programmer will not function properly in Port (1) owing to different system control lines available. For simplicity, this manual assumes that the programmer is plugged into Port(4).
An intelligent programming algorithm is used to program both the 32K and 64K EPROMs. Typically the length of time to burn a 32K EPROM is less than 5 minutes. The 64K EPROM will require generally less than 15 minutes.

Code: FILENAME DESCRIPTIONApplications in ROM Module HP-5061-7246 Diagnostic ROM Service Manual Introduction The diagnostic ROM is a preprogrammed ROM (read only memory) module designed to be inserted into port number one (the left front port) of the HP-71. It is designed to take control of the HP-71 by disabling the system ROM. It will detect most hardware failures by exercising all of the ICs and the bus. It can not, however, determine if software is operating properly except when certain software responses are expected in a particular test and are not received.
Special Acknowledgment The 16KB diagnostic ROM is a take over module that take control of the machine as soon as its plugged into the computer. Because of its nature, its not an ROM easy to clone, but thanks to Jean-François Garnier, who has the skills, took the time to do it. He created a 64KB image to make it easier for emulators its Emu71/DOS to run it.

This product has been superseded by the HP-82478A FORTH/Assembler ROM with Debugger. HP-82478-60001 Debugger Owner Manual Introduction The debugger offers programmers the ability to simulate assembly language on the HP-71B handheld computer. If your programming experience is in BASIC, you may be drawn to assembly language by its promise of greater speed and flexibility. Software development at this level requires the same approach to inspection and proof - the tempering of logic often referred to as the debugging stage. In assembly language this process is much more focused since execution flow and register usage is at the lowest level, in the Central Processing Unit (CPU), where the built-in protections afforded by an operating system are not available. In many cases the best method to certify programming logic is by direct testing. You need a tool which allows you to follow execution and register contents at each step - a debugger. In tandem with the FORTH/Assembler ROM or with PC-based Saturn Assemblers, the debugger provides an accurate, affordable, and portable tool for assembly language development on the HP- 71. Its many options allow you to customize its operation, even midway through a debugging session. Its modularity is designed to allow the addition of more features through assembly language enhancements.
