This box allowed up to 16 TRS computer to be networked. Three network boxes were released by Tandy (I, II and III).\
The Network II required verbal communication between the server operator and the remote user, and data transfer had to be completed one user at a time.\
The network III allowed automated control of the network so that users could easily access programs and data stored on the server's storage device.

subtitle: Stringy Floppy drive
text: |-
The Exatron Stringy Floppy (ESF) was a low-cost data—storage system that fitted the gap, between cassettes and disk drives.\
The system was based on a miniature endless—loop tape cartridge called a "wafer".\
The amount of data that could be recorded on a wafer depended on the length of tape in it, typically, a 50—foot wafer could hold at least 40 KB of programs or data.
**Matt** reports to us:\
A curiousity about the model 1, CPU SPEED had a direct relatonship with STORAGE CAPACITY. if you doubled the clock speed of your MODEL 1 CPU you doubled the amount of data you could store on your stringy floppies. this is a feat that no other computer no matter how many ghz you have in your PC can do today without using compression.

This is an extremly rare [TRS-80 Model 1](/museum/tandy-radio-shack-trs-80-model-i/) clone, re-using the case of an other clone: The Komtek 1 (from Hong-Kong).
It's equiped with a Level II basic and powered by a Zilog Z80 cpu.
According to the labels found underneath the case, the computer could be delivered with different options:\
\- 16 KB RAM\
\- 32 KB RAM\
\- 48 KB RAM\
\- Color board (!)\
\- Dual Language\
\- Control functions\
\- Single density disk controller\
\- Double density disk controller\
\- BASIC printer (surely BASIC instructions to access the printer)
