Their 71 card-reader-port RAM modules went in 32K increments up to 160K IIRC. I drooled over that biggest one when it was in the EduCalc catalog, but I had to set myself a budget and I ended up with the 96K. I also have their 64K front-port RAM.
They had a CR-32/32 which was a card-reader-port 32K RAM and 32K OTP EPROM, the 71-PO1 EPROM programmer, front-port EPROM modules for HP-75, and the CMT-71 waterproof case for the 71, which, with its built-in heater, could be used with the big rechargeable-battery waist belt so surveyors could do their field work down to -40 deg. This is from my EduCalc catalog #35.
Looking in a CMT Hand-Held Solutions magazine from Jan '88, I see also the Multicase which was similar to the waterproof case mentioned above but also included a 64x240 dot LCD, a 128K mass-storage device, 82164A-compatible RS-232 interface, and status indicators.
