...."The problem that a lot of people have is a lack of response from the remote control. I have had the SDT-9077P for nearly a year, and recently bought a Panomax DTS-80P, which didn't suffer this problem. So I swapped front panels between machines, and the fault went with the Digi panel. AHA! So I got out my trusty oscilloscope, and checked the waveform from the output of the Infrared unit. The fall time of the wave is in the nanoSec area, but the rise time of the DTS-80P is 2 uSecs, the SDT-9077P is more than 10 uSecs. Both the IR circuits are identical, so it must be the innards of the IR chip. This would allow any noise to double trigger in the firmware. So I got a hex Schmitt trigger IC (sn74C14) from Dick Smith and put 2 of the inverters in series (to maintain signal polarity) between the IR unit and the input of the main board. IT IS NOW 100% RELIABLE."..
Many thanks to Papa for providing this excellent guide
Subject: Poor response to commands from the remote control.
Modification to Digicrystal SDT-9077P and Panomax DTS-80P recorders.
Required parts. (Available from Dick Smith Electronics or equivalent)
1 x 2.7K 1/4 watt Resistor
1 x 74C14 CMos integrated circuit (DS part number Z5413)
1 piece of 'Versa Strip' (formerly Veroboard) trimmed to size.

IC
Locate the surface mount Resistor R20 (label value is 101) on the front panel
circuit board and gently remove it. (no longer required))
Work out which are pins 1, 3 and 8 on the header for the cable which
connects to the main board. (Hint: One end of R20 went to pin 3)
NB: The header pins on Digi are in the reverse direction to the Pano.(see
pictures)
Mount the 2.7K resister and IC on the 'versa strip' piece according to
the wiring diagram. Make sure there are no unwanted shorts between pins.
About the CMos IC.
1. According to the data sheet the Vcc should be at least 4.5V, but it is
quite tolerant of lower voltages. Because of this, we will use the supply
from pin 1 on the header, approx. 3.25V
2. All inputs on a CMos chip should be connected to a Hi or Lo voltage, as
a floating input produces some weird effects. That is why the cct diagram has
unused sections connected up.
After making sure that the cct is wired correctly on the 'versa strip',
connect pin 7 of the IC to pin 8 on the header (0V or earth)
Connect pin 14 of the IC to pin 1 on the header (3.25v supply)
Connect pin 1 of the IC to the output of IR receiver (where R20 was connected)
Connect pins 4/5 of the IC to pin 3 on the header.
This circuit is fairly non-critical, but keep the leads sensibly short.
I will be adding more to this section as time allows

Panomax version 4 Papas latest version of this
brilliant software now with optional repair mode (/R)
Panomax version 3.2 Papas tinyUDF windows disk reader and copy program
This will has more functionality than Sigmatek or PVR101dsk but is much easier to use because
it serves the of the same name that "list" does on the PVR and automatically
renames it to *.ts but more importantly fixes the chaseplay file copy issue of
Sigmatek and PVR101dsk.
Panomax1 beta
version of the above tynyUDF reader - slower transfer speed than Panomax but may
work better for some.
