quite correct .... MemStart is not defined in TIS-CWG. It ought to be
there, probably on p84 in a new section before special workspace locations.
The text of the section should be something like:
MemStart is the address of the first word above the special RAM
locations at the bottom of the memory map. Because different transputer
variants store different information in these special RAM locations
MemStart differs between variants. The values for current processors
are
IMS T212: #8024
IMS T414: #80000048
IMS T425: #80000070
IMS T800: #80000070
the values for these and other variants are given in the relevant
datasheets.
