TRS 80 Model II

TRS 80 Model II ( Model Number: 26-4002) - 01
The TRS-80 model II, is the obscure brother of the TRS-80 family.
Many internet pages deal with the models 1,3 and 4 but omit the model 2...
This is maybe because the TRS-80 Model 2 was intended to be a business
computer for use in offices and labs. Thus it is equiped with a full height
Shugart 8'' drive with a capacity of 500k which is a lot compared to the
87k offered by the TRS-80 Model 1 system disk.
It is also possible to connect up to 4 floppy disk units, so you could
have 2MB disk space online ! 

It runs under TRSDOS, but can also achieve CP/M compatibility. 

Options for the machine included a hard disk controller,
an arcnet network card, a graphics card and a 6 MHz 68000 board set
with extra memory (up to 512K) so it could run XENIX.
