The file basic_1.0_19750302_cpyApr02.ptp was send to me by Al Kossow
to have a look at it. This file is a copy of the paper tape here:

   http://www.computerhistory.org/revolution/personal-computers/17/312/1142 

A hexdump from the start of the tape shows how to load it into machines:

00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

00000020  00 00 00 00 e3 be 23 e3  c2 61 05 7f c5 7e 23 fe  |......#..a...~#.|

00000040  7d 93 c9 00 00 00 00 00  00 00 00 00 e1 5e 23 56  |}............^#V|

The tape has a leader with 0 bytes as usual, the first data byte is 6a,
I don't know what it is for. BASIC starts with c3 16 02, a jump instruction
to the warm start routine, from here on the tape needs to be loaded at
address 0. So to convert it to a loadable Intel hex file use:

	bin2hex -i 28 -o 0 basic_1.0_19750302_cpyApr02.ptp basic4k10.hex

If you load this tape into a machine and run BASIC from address 0 it
will just print READY to the terminal, it jumps to the warm start routine.
With a bit of dissassembly the address for the cold start routine can be
found at 107EH:

	107e - LD	SP,114A
	1081 - LD	HL,0216
	1084 - LD	(0001),HL
	1087 - CALL	068D
	108a - LD	HL,1131
	108d - CALL	03CA
	1090 - LD	HL,(114A)
	1093 - LD	(01C6),HL
	1096 - CALL	02F5
	1099 - RST	10

So before you toggle the Run key set the address bus to 107E:

	A15 A14 A13 A12  A11 A10 A09 A08  A07 A06 A05 A04  A03 A02 A01 A00
	OFF OFF OFF ON   OFF OFF OFF OFF  OFF ON  ON  ON   ON  ON  ON  OFF
        -------+-------  -------+-------  -------+-------  -------+-------
               |                |                |                |
               1                0                7                E

Now toggle Examine to set the PC to this address, and then toggle Run
to start BASIC at the cold start entry.

With this it runs through a similar configuration dialog as the later
versions. Better is to patch the jmp @ 0 to the cold start entry, the
warm start entry will be written there to address 1, see disassembly
above.

This is done already in basic4k10.hex I've created from this tape.

If you use a VT-100/ANSI compatible terminal you'll notice,
that the display will get confused to some degree. This is because
the following bug in the code:

>>> d10f0
Adr    00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f  ASCII

After BYTES FREE the line is terminated with CR ESC LF and the ESC will
confuse all terminals using it for the control sequences. So the
offending line better is patched:

1110 - 53 20 46 52 45 c5 0d 0a 00 00 0d 0a 38 30 38 30  S FRE.......8080

This is done already in basic4k10.hex I've created from this tape.
