pdp7-unix is a project to resurrect Unix on the PDP-7 from scans of
the original assembly code done by
[Norman Wilson](http://www.cs.toronto.edu/~norman/pers/index.html).
The scans of PDP-7 Unix are in the [Unix Archive](http://www.tuhs.org/)
[as the files 0*.pdf](http://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/).
as the files
[0*.pdf and 1*.pdf](http://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/).
## Current Status
### January 2020
Unixv0 is running on a real PDP-7 at the Living Computer Museum. [Youtube](https://www.youtube.com/watch?v=pvaPaWyiuLA).
### October 2019
A second notebook with missing sources has been
discovered and scanned. New files are being added to the scans
directory as they are typed in!
A second notebook with missing sources has been discovered and
scanned. The original commands are now in the disk image
(only the B compiler, date, mv and od are modern programs).
Graphics programs (including Space Travel) are being debugged
along with a simulation of the display hardware.
### March 2016
We've written an assembler, a user-mode simulator and
commented several source files. We now have these utilities running:
as, cat, chmod, chown, chrm, cp, date, ln, ls, mv, stat. We have a working
shell with some functionality missing. We have a working filesystem and
we can now boot the kernel, launch init, login, get to a shell prompt and
run the utilities.

the kernel, launch init, login, get to a shell prompt and run the

Things to do: bring the
system fully up on a PDP-7 system, fix any bugs and document everything.
We have a [real PDP-7](http://physics.uoregon.edu/outreach/movies/pdplives/)
and [SimH](http://simh.trailing-edge.com/) as target platforms.
## Building pdp7-unix
pdp7-unix requires [Perl5](https://www.perl.org/) to build.
pdp7-unix requires [Perl5](https://www.perl.org/) to build,
plus the perl DateTime package (debian/Ubuntu libtimedate-perl).
To compile it:
`make`
`make pdp7`
## Running pdp7-unix
You will need [simh](http://simh.trailing-edge.com/) 4.0 to run pdp7-unix. You can get the source code [here](https://github.com/simh/simh). On 64-bit systems, you may need to set the C compiler's optimisation level to -O1.

NAME format of file system
.sp
SYNOPSIS --
.sp
DESCRIPTION The RB09 fixed head disk has 8,000 64-word
blocks on each of its two surfaces. Unix uses
the second surface (physical blocks 8,000 to
15,999) and numbers them from logical block 0 to
logical block 7,999. The following discussion
refers to logical blocks.
.sp
The Unix filesystem is divided into 8,000 blocks
of 64 words per block. Block 0 is the "sysdata"
block. The first word points to the first block
of the free-storage map. Each block in the
free-storage map is structured as follows: the
first word is the block number of the next block
in the free-storage map, or zero if this is the
end of the free-storage map. The next nine words
hold free block numbers, or zero (no block
number).
.sp
Block 1 on the filesystem is unused. (?)
.sp
I-numbers begin at 1, and the storage for
i-nodes begins at block 2. Blocks 2 to 711
contain the i-nodes, with five consecutive
i-nodes per block. Certain i-nodes are reserved
for special files, directories and devices:
.sp
1 The core file written by "sys save" or a
bad system call
2 The "dd" directory directory
3 The "system" directory
6 The "ttyin" special file
7 The "keyboard" (graphic-2) special file
8 The "pptin" (paper tape reader) special
file
10 The "ttyout" special file
11 The "display" (graphic-2) special file
12 The "pptout" (paper tape punch) special
file
.sp
There is only one file system which is always
mounted; it resides on the RB disk. This device
is also used for swapping. The swap areas are at
the high blocks on this device: blocks 6,400 to
7,999. These blocks do not appear in the free
list.
.sp
Each i-node represents one file. The format of
an i-node is as follows, where the left column
represents the offset in words from the
beginning of the i-node:
.sp
0 flags (see below)
1 first indirect block or contents block
...
7 seventh indirect block or contents block
8 user ID of owner
9 link count
10 size in words
11 unique value assigned at creation
.sp
The flags are as follows:
.sp
400000 i-node is allocated
200000 large file
?????? allocated bit (always on)
000040 special file
000020 directory
000010 read, owner
000004 write, owner
000002 read, non-owner
000001 write, non-owner
.sp
The allocated bit (flag ??????) is believed even
if the i-node map says the i-node is free; thus
corruption of the map may cause i-nodes to
become unallocatable, but will not cause active
nodes to be reused.
.sp
Word number n of a file is accessed as follows:
n is divided by 64 to find its logical block
number (say b) in the file. If the file is small
(flag 200000 is 0), then b must be less than 7,
and the physical block number corresponding to b
is the bth entry in the address portion of the
i-node.
.sp
If the file is large, b is divided by 64 to
yield a number which must be less than 8 (or
the file is too large for UNIX to handle).
The corresponding slot in the i-node address
portion gives the physical block number of an
indirect block. The residue mod 64 gives a
word offset in the indirect block, and the
word found there is the physical address of
the block corresponding to b.
.sp
If block b in a file exists, it is not necessary
that all blocks less than b exist. A zero block
number either in the address words of the i-node
or in an indirect block indicates that the
corresponding block has never been allocated.
Such a missing block reads as if it contained
all zero words.

DESCRIPTION
.in 8
The RB09 fixed head disk has 8,000 64-word
blocks (100 tracks of 80 blocks)
on each of its two surfaces. The Unix filesystem
is stored in the first 80 tracks of
the second surface (physical blocks 8,000 to
14,399 -- physical tracks 100 to 179)
and numbers them from logical block 0 to
logical block 6,399.
.sp
The Unix filesystem is divided into 6,400 logical blocks
of 64 words per block. Block 0 is the "sysdata"
block. The first word points to the first block
of the free-storage map. Each block in the
free-storage map is structured as follows: the
first word is the block number of the next block
in the free-storage map, or zero if this is the
end of the free-storage map. The next nine words
hold free block numbers, or zero (no block
number).
.sp
Block 1 on the filesystem is unused. (?)
.sp
I-numbers begin at 1, and the storage for
i-nodes begins at block 2. Blocks 2 to 711
contain the i-nodes, with five 12-word
i-nodes per block. Certain i-nodes are reserved
for special files, directories and devices:

.sp
There is only one file system which is always
mounted; it resides on the RB disk.
.sp
The last twenty tracks of the second disk surface
are use for bootable images and swapping:
.sp
Each physical track from 180 to 189
contains a bootable system image of 3K words.
.sp
Each physical track from 190 to 199 is used to swap
a user process (4K words plus a 64-word swapable
"userdata" area).
.sp
Each i-node represents one file. The format of
an i-node is as follows, where the left column
represents the offset in words from the
beginning of the i-node:
.sp
.nf
0 flags (see below)
1 first indirect block or data block
...
7 seventh indirect block or data block
8 user ID of owner

The following explanation separates out each move onto its own line.
Further it decodes each move into binary, and separates out and interprets
the three distance, visibility and direction fields. Finally each line
ends with a comment indicating which input command generated the output move:
move move move dist vis direc dist vis direc input
number octal binary binary binary binary decimal text text command

This can be interpreted on a grid by starting at ma (row n, column a)
denoted by a 0 and following the moves denoted by their corresponding
move number. Note that after the final move, f, the location being
outside of the character box corresponds to the location ma of the
next character to the right. To the right is the same character where
x:s denote drawn pixels and . denote undrawn pixels.

" In both cases 10 blocks worth of data is either transferred from

" (write). A block is the same as a segment, each comprising 64 words.

" The location on disk is controlled by the variable "side" and the

"
" dskio takes the block address passed in AC, divides it by 80
" to get the track address, and as a remainder the segment address.
" Both are then re-encoded as BCD, shifted to the correct bit
" positions (explained below) and ORed together with the value of
" the "side" variable (representing the hundreds flag in the disk
" address). This disk address is then passed on to the disk just
" before starting the transfer in chunks of 10 segments each.
"
" The disk address for RB09 disks is formatted like this:
"
" * Bit 0 not used

" * Bits 2-5 Tens digit for track address as BCD
" * Bits 6-9 Units digit for track address as BCD
" * Bits 10-13 Tens digit for segment address as BCD
" * Bits 14-17 Units digit for segment address as BCD
