## Notes on oskit: Unix 7th Edition system on RP04 volumes
|
|
|
|
### Proviso
|
|
|
|
The current disk image is the plain 'Keith_Bostic' distribution
|
|
**without any adoptions of further configurations**.
|
|
Especially no program was rebuild to use the floating point simulator.
|
|
|
|
**All programs using floating point arithmetic will core dump !!**
|
|
|
|
Most in fact work fine because floating point is rarely used, but a simple
|
|
```
|
|
awk "BEGIN { print 1/100 }" /dev/null
|
|
```
|
|
|
|
will generate a `core` because awk for example does use floating point
|
|
arithmetic.
|
|
|
|
**So far only minimal testing on the CmodA7 system (672 kB memory) done.**
|
|
|
|
### General remarks
|
|
See notes in [w11a_os_guide.md](../../../doc/w11a_os_guide.md) on
|
|
1. I/O emulation setup
|
|
2. FPGA Board setup
|
|
3. Rlink and Backend Server setup
|
|
4. Legal terms
|
|
|
|
### Installation
|
|
A disk set is available from
|
|
http://www.retro11.de/data/oc_w11/oskits/u7ed_rpset.tgz
|
|
|
|
Download, unpack and copy the disk images (*.dsk), e.g.
|
|
```bash
|
|
|
|
cd $RETROBASE/tools/oskit/u7ed_rp
|
|
wget http://www.retro11.de/data/oc_w11/oskits/u7ed_rpset.tgz
|
|
tar -xzf u7ed_rpset.tgz
|
|
```
|
|
|
|
### Usage
|
|
|
|
- Start backend server and boot system
|
|
(see section Rlink in [w11a_os_guide.md](../../../doc/w11a_os_guide.md))
|
|
```
|
|
boot script: u7ed_rp_boot.tcl
|
|
example: ti_w11 <opt> @u7ed_rp_boot.tcl
|
|
where <opt> is the proper option set for the board.
|
|
```
|
|
|
|
- Hit `<ENTER>` in the xterm window to connect to backend server.
|
|
The boot dialog in the console `xterm` window will look like
|
|
(required input is in `{..}`, with `{<CR>}` denoting a carriage return:
|
|
```
|
|
{boot}
|
|
Boot

|
|
|
|
**Note**: one has to type `boot` to start the 1st level boot loader. There
|
|
is no initial prompt ! Just type `boot` followed by an enter to get going.
|
|
|
|
Now you are at the shell prompt and can exercise the system, e.g.
|
|
```
|
|

/dev/rp0 5311

/dev/rp3 130595
|
|
```
|
|
|
|
There is no `halt` or `shutdown` command, the proper way to shutdown
|
|
is to do a few `sync`
|
|
```
|
|
{sync}
|
|
{sync}
|
|
{sync}
|
|
```
|
|
|
|
and just terminate the server session with a
|
|
```
|
|
.qq
|
|
```
|
|
|
|
command.
