1. Load New PROM Content
The “Load New PROM Content” option is used to load new content into a PROM
slot. The PROM data can be uploaded as a binary or Intel hex format file. If
a binary format is chosen, the load address must be specified (up to four hex
digits). The example below shows loading PROM content from an Intel hex file.
File transfer can be aborted by pressing CTRL-C or raising the left AUX
switch.
===== Load New Prom Content =====
Enter PROM Address in hex (or return for .HEX file):
Send .hex file now...
(initiate simple send file operation from the PC – not XMODEM)
2. Change Description, Change Load Address, etc.
Options 2 – 6 are fairly self explanatory. Note: The “Change Load Address”
option does NOT magically relocate already assembled code. This option is
used if you accidentally typed in the wrong address when initially loading a
binary PROM file.

C. Serial Port Menu
The serial ports on the Altair Clone can be configured in a variety of ways
to match the requirements of the software to be run. By default, port 1 is a
2SIO port (Motorola ACIA) at octal address 020/021. Serial port 2 defaults to
an SIO port at address 006/007 (the cassette interface port). If you pur-
chased an assembled Clone, serial port 1 is the upper DB-25 on the rear panel
and serial port 2 is the lower connector. If using the optional Audio Cas-
sette Interface, you’ll probably want to configure Port 3 to be the cassette
I/O port (SIO at 006/007, 300 baud, 8N1) instead of Port 2.
When the Serial Port Menu option is chosen from the main menu, the current
serial port settings are displayed as shown below (Note: The port settings
shown are also the default settings).
===== Serial Port Settings =====
Port Type I/O Rate Other
---- ---- ------- ---- --------
1 2SIO 020,021 9600
2 SIO 006,007 9600 8N1
3 2SIO 024,025 9600
Enter Serial Port to Change (x to Exit):
After entering the serial port number to change, this menu is displayed:
===== Serial Port Menu =====
1) Change Port Type
2) Set Baud Rate
3) Set CTS, RTS Usage
4) Set Word Length, Parity, Stop Bits
x) Exit this Menu
