There's a TINST program that allows you to set the terminal for Turbo Pascal. List of terminals supported by Turbo Pascal: Turns out there's terminal remapping built into apple cpm and a configuration program called CONFIGIO (written in basic!). So there's a "software code" that gets mapped to a "hardware code". I think the idea is to remap the Soroc IQ-120 to whatever terminal you are actually using and you can even map the Soroc IQ-120 to itself (set the hardware codes to match the software codes). It's just a simple translation, the "hardware code" is what's translated and sent to the hardware when it sees a "software code".

So I modified the rs232 terminal to strip out the high bit with "data &= 0x7f;" ./mame apple2p -sl3 ssc -sl3:ssc:rs232 terminal and after hitting RESET after booting, and typing IN#3 and PR#3 you can type with the terminal keyboard and send output to the terminal. Output is simultaneous to the screen and the terminal, and the keyboards work simultaneously as well. One thing that's interesting is that CTRL+C from the terminal will only be processed if there is an INPUT statement, so you can't break basic programs that are running. Micro Display Systems made a full page display called the "Genius Full Page Display Model 101" that had 57 lines * 80 column resolution with RS232 and Apple specific versions. That would have been pretty neat. I think that once 80 columns was ubiquitous with the //e that demand for external terminals faded along with the additional complexity and high cost.

(This seems to have been one of the most common formats for serial ASCII transmission in the 1960s and 1970s, even after IC UARTs started to make the framing parameters more easily configurable. It became highly undesirable when 8-bit character sets began to proliferate in the 1980s.) Last edited by AJR; 02/16/23 03:06 AM.

I wanted to find a way to press CTRL+Open Apple+ESC to get into the control panel of the apple2gs, but LCTRL+LALT+ESC doesn't get passed on with Ubuntu.

One strategy is to assign another key like PgUp to both Open Apple and CTRL, like PgUp, so you can type PgUp + ESC and that will work.

I tried assigning PgUp to CTRL and OpenApple and ESC, but pressing all three simultaneously doesn't seem to work. It seems that ESC must be pressed slightly later than CTRL+OpenApple.

Another strategy is to use lua to press some keys:

So first, let's figure out the names of the ports and fields we need:

Code

[MAME]> function printt(t) for a,b in pairs(t) do print(a,b) end end
[MAME]> printt(manager.machine.ioport.ports)
:a2_config	sol.ioport_port*: 0x5645a8e82b28
:macadb:KEY0	sol.ioport_port*: 0x5645a8e5cf88
:macadb:KEY1	sol.ioport_port*: 0x5645a8df18a8
:macadb:KEY2	sol.ioport_port*: 0x5645a8e34068
:macadb:KEY3	sol.ioport_port*: 0x5645a8dc77a8
...

[MAME]> printt(manager.machine.ioport.ports[":macadb:KEY3"].fields)
Command / Open Apple	sol.ioport_field*: 0x5645a8efe0e8
Esc	sol.ioport_field*: 0x5645a8efa808
Option / Solid Apple	sol.ioport_field*: 0x5645a8eff718
Control	sol.ioport_field*: 0x5645a8f068d8
...

Once we know the name of the port and the fields we need, we can assign them to some variables and make a coroutine function:

Code

 opkey = manager.machine.ioport.ports[":macadb:KEY3"].fields["Command / Open Apple"] 
 esckey = manager.machine.ioport.ports[":macadb:KEY3"].fields["Esc"]
 ctrlkey = manager.machine.ioport.ports[":macadb:KEY3"].fields["Control"]


function cofunc()
 print("press op, ctrl") 
 opkey:set_value(1) 
 ctrlkey:set_value(1) 
 emu.wait(2/60) 
 print("press esc") 
 esckey:set_value(1)
 emu.wait(2/60) print("release")
 opkey:set_value(0) 
 esckey:set_value(0) 
 ctrlkey:set_value(0)  
end

function pressctrlopesc() co1 = coroutine.create(cofunc) coroutine.resume(co1) end

pressctrlopesc()
