Here's what I stole shamelessly from the EDUCALC catalogue #37p36
begin of stolen text:
EPROMS (Front Port) [CMT]
Store up to 32k or 64k of custom application programs. Unlike the RAM modules these modules may be removed from your HP-71 front port without losing their memory, just like any HP application pack. They can be intentionally erased with ultraviolet light and reprogrammed many times by an EPROM burner or through our EPROM service. Better than application packs, they are updateable.
CMT-71P01 EPROM programmer for HP-71 front port EPROMS
A completely self-contained device, that allows you to program CMT-71-32KE or CMT-71-64KE EPROMS. It connects to the HP-71 through a front port. The programmers RAM is accessible through commands in the HP-71. To use the programmer in the 64 k mode, a FORTH ASSM ROM needs to be installed into anther HP-71 port. Additional software to help build the EPROM image is supplied on theCMT-71 EPROMs along with self test programs. The EPROMs will need to be erased with ultraviolet light before programming. The manual contains full operating instructions. It assumes, you have some working knowledge of the general use of the HP-71 and the hexadecimal number system. Most references to address or data will be made in hex. Typically to burn a 32K EPROM takes less than 5 minutes. The 64K EPROM generally takes less than 15 minutes.

Note: this is NOT the HHP (Hand Held Products) EPROM or EPROM/RAM module for the card reader port. These modules were more simple to use, because they had a socket, which held industry standard EPROM chips. These chips could be programmed with any programmer, not limited to the special CMT programmer.
