/******************************************************************************************
The Alphatronic PC 16 was modeled after the earlier 8 bit Alphatronic PC – on the outside
a typical "breadbox" home computer case with an integrated keyboard and external floppy disk drives.
Coming from a typewriter company, it had ambitions for office use - its high price and mismatched
intended use and design coupled with its release date gave it little success. It was released
in the early phase of DOS computers, when IBM’s standard was not yet set into stone, but would
vanquish all "incompatible" solutions within short time.
The start screen allows the selection
of functions by entering the first (two) letters of the command or using the F-key as shown on the screen.
CPU: 8088@5MHz - RAM: 64KB, can be extended to 128KB - ROM: 64KB (monitor and BASIC)
Keyboard: ALP: the key marked with a Greek alpha character makes the computer/printer combo a
typewriter, everything is typed "through".
BRK: BREAK stops a BASIC program or acts like CTRL-C
GRAPH: allows the entering of semigraphics characters, locks into place like CAPSLK
numeric and BTX function keys:
UP, DWN, LFT and RWT are marked with their respective arrows and move the cursor
DEL is marked (R) for BTX mode and reloads the page
CLR is marked (i) in BTX mode for “info” and loads the start page
= is marked with a page that’s being turned and is a "reveal" key, e.g. for quizzes
<-/ is marked with an envelope, it loads BTX’s messaging service
the + and – keys aren’t defined yet in BTX mode, they are marked with a page and an arrow each
* shows a screen with a black/white contrast and turns BTX screen attributes on and off
/ has a telephone receiver and three lines and is the online/offline/dialing key

Graphics options: Standard monitor cassette (Cinch for bw and DIN for SCART/RGB connectors) 40/80x21/25
characters, Full graphics cassette (512x256 pixels, 16 colours, vector graphics, 64K video RAM),
BTX cassette (compatible with the standard monitor cassette but includes a modem for BTX functionality)
Floppy: 1 or 2 5.25” DSDD 40 tracks x 5 sectors x 1024 bytes
Connectors: joystick, cassette recorder (600/1200 BD) FSK, printer (recommended: TRD 7020 or
GABRIELE 9009 typewriter, V24), floppy, module slot
Options: 2 versions of an autonomous processor PCB (Z8671 based, programmable in TinyBasic
via the PC 16 Terminal, operates independently after programming), connects to the printer port
