PB0-PB3 is connected to U601 (74LS145) which select a column to scan

|

PB6-PB7 forms the cassette interface
|
||||
|
||||
The serial bitbanging perform enreliable atm, can be poor original code or inexact CPU timing.
|
||||
Best results is achieved with 8 bit at 9600 baud as follows:
|
||||
|
||||
mame e100 -window -rs232 null_modem -bitbngr socket.127.0.0.1:4321
|
||||
|
||||
Start the favourite Telnet client towards the 4321 port and exit the startup screen of MAME.
|
||||
At the "Esselte 100 #" prompt change to 8 bit communication and start the terminal mode:
|
||||
|
||||
POKE (69,1)
|
||||
TERM(9600)
|
||||
|
||||
It is now possible to send characters from the Esselte screen to the Telnet terminal. When a
|
||||
carriage return has been sent to the terminal the Esselte 100 goes into receiving mode until
|
||||
it receives a carriage return from the terminal at which point it will start sending again.
|
||||
|
||||
TODO:
|
||||
- Fix key mapping of the Ctl-PI exit sequence to get out of the TERM mode.
|
||||
- Fix timing issues for the PIA bit banging, could be related to that the CPU emulation is not
|
||||
cycle exact or the ROM code is buggy

* History of Didact
|
||||
*------------------
|
||||
* See didact.cpp
|
||||
*
|
||||
* The Esselte 100 was an original design with a CRT and a full Keyboard that also had a BASIC interpreter
|
||||
* extended with commands suitable for educational experiments using the exapansion bus and its built in
|
||||
* io control capabilities.
|
||||
*
|
||||
* The Esselte 1000 was an educational package based on Apple II plus software and litterature but the relation
|
||||
* to Didact is at this point unknown so it is probably a pure Esselte software production. If this branded
|
||||
* distribution is recovered it will be added as a clone of the Apple II driver or just as softlist item.
|
||||
*
|
||||
* Misc links about the boards supported by this driver.

The serial bitbanging perform enreliable atm, can be poor original code or inexact CPU timing.
|
||||
Best results is achieved with 8 bit at 9600 baud as follows:
|
||||
|
||||
mame e100 -window -rs232 null_modem -bitbngr socket.127.0.0.1:4321
|
||||
|
||||
Start the favourite Telnet client towards the 4321 port and exit the startup screen of MAME.
|
||||
At the "Esselte 100 #" prompt change to 8 bit communication and start the terminal mode:
|
||||
|
||||
POKE (69,1)
|
||||
TERM(9600)
|
||||
|
||||
It is now possible to send characters from the Esselte screen to the Telnet terminal. When a
|
||||
carriage return has been sent to the terminal the Esselte 100 goes into receiving mode until
|
||||
it receives a carriage return from the terminal at which point it will start sending again.
|
||||
|
||||
TODO:
|
||||
- Fix key mapping of the Ctl-PI exit sequence to get out of the TERM mode.
|
||||
- Fix timing issues for the PIA bit banging, could be related to that the CPU emulation is not
|
||||
cycle exact or the ROM code is buggy
