## The Palivere and variations
|
||||
<!-- This file is automatically generated. Do not edit. -->
|
||||
|
||||
The Tartu Palivere is a 1988 Z80-based computer from Estonia. It is a CP/M
|
||||
machine with 64kB of RAM, running off a 2MHz ꃣ0e30
|
||||
clone; it operated off punched tape, cassette, external hard drive or floppy, and was notable as being the first ever computer with an Estonian keyboard.
|
||||
|
||||

||||
<img src="tartu.jpg" alt="The Tartu computer's developer Leo Humal working with one."/>
|
||||
</div>
|
||||
|
||||
From a floppy disk perspective, it is interesting because the floppy drive
|
||||
interface is almost entirely handled in software --- necessary at the time as
|
||||
the usual floppy disk interface chip at the time, the ⎲fba5
|
||||
of the WD1793), was hard to find. Instead, the floppy controller board was
|
||||
implemented entirely using TTL logic. Despite this, the encoding is fairly high
|
||||
density, using MFM and with up to 780kB on a double-sided 80 track disk.
|
||||
|
||||

|
||||
</div>
|
||||
|
||||
FluxEngine supports reading Tartu disks with CP/M filesystem access.

## Options
|
||||
|
||||
- Format variants:
|
||||
- `390`: 390kB 5.25" 40-track DSDD
|
||||
- `780`: 780kB 5.25" 80-track DSDD
|
||||
|
||||
## Examples
|
||||
|
||||
To read:
|
||||
|
||||
- `fluxengine read tartu --390 -s drive:0 -o tartu.img`

The Tartu Palivere is a 1988 Z80-based computer from Estonia. It is a CP/M
|
||||
machine with 64kB of RAM, running off a 2MHz КP580ВМ80А, a Soviet Union 8080
|
||||
clone; it operated off punched tape, cassette, external hard drive or floppy, and was notable as being the first ever computer with an Estonian keyboard.

|

|

From a floppy disk perspective, it is interesting because the floppy drive
|
||||
interface is almost entirely handled in software --- necessary at the time as
|
||||
the usual floppy disk interface chip at the time, the КR1818VG93 (a Soviet clone
|
||||
of the WD1793), was hard to find. Instead, the floppy controller board was
|
||||
implemented entirely using TTL logic. Despite this, the encoding is fairly high
|
||||
density, using MFM and with up to 780kB on a double-sided 80 track disk.

FluxEngine supports reading Tartu disks with CP/M filesystem access.
