The LCD has 10 driver chips, which store graphics bits directly.  The driver chip is the HD44102.  I would recommend reading the datasheet for HD44102.  Each driver chip controls a specific reqion of the LCD, as follows-

Drivers 0-3 and 5-8 all drive 50 x 32 of dots each, while 4 and 9 only drive 40 x 32 dots.
 
(the unused dots in 4 and 9 represent some 'free ram' for use by programmers).
 
The dot content is updated by writing data to each of these chips.  To select a driver for access, you must write a 1 to a specific bit on port B9 or BA.

Classic Article Repubs

We hope to republish one or more articles from the Golden Era of the Model T every month:

One-Liners

This is a collection of Microsoft BASIC programs that

  • Do something interesting or useful
  • With only a single line of code

One-liners are bite-sized computer programs on a human scale. You are encouraged to type them in manually (by hand) and study their operation.

Model 100/102 Compatible One-Liners

File-Transfer and Storage

We still use Model Ts today, so file transfer to/from desktop and modern laptops is an important issue. There are multiple alternatives, from simple text file transfers using TEXT, TELCOM, or BASIC, up to dedicated file transfer protocol client and servers.
