Just checked, don't have any of these drives but do have a sack bag of stuff from a couple of Denford Starmill conversions, Need to get these on Ebay.
Also have the guts from a Roland PNC - 3100 and a Roland PNC - 2200John S -
Hi Asto, i'm a bit confused here. The first picture you posted shows a parker sd2 drive, but the second picture showing the component is of a parker cd20 drive.
Is the lathe an Easiturn, if so the drive should be a cd20, and to have an led showing it would seem the drive is a cd20 rather than a sd2.
This morning I attached three wires on the board in place of removed transistor and at the other end a triple female socket. Then started playing with several types of transistors that I'd found handy and guess what... The one that made the SD2 play music again was the TIP145. So the TIP32-C is the closest equivalent as its collector current is 3Amps while the TIP145 is Ic=10Amps.
I think the supplier's location is...518, Purley Way, Croydon, CR0 4RE
Conclusion...Very few things may remain unidentified in this forum.
I am glad I've joined.
Ps. I wish to thank Irving as well for helping me to narrow my search_Sorry for any syntax errors.

I only have machines driven by SD2's. So, both pictures are from the SD2 drive. What you see in the 2nd image is the component side of the PCB which is visible_ copper side_(well that's o.k double sided board) in the first photo.
Thanks John S!
Glad you got somewhere with it.If the nagging gets really bad......Get a bigger shed:naughty:
It is printed on the old transistor but it has to be something like irving said. This code does not belong to any known transistor family.
Anyway my SD2 drive is alive again and runs fine.
Now I have to see how much hope do I have to fix the problem for my x-axis stepper motor losing direction.
I used to work for motorola in a past life. It was common for them to disguise parts like Irving said. They would always use part of the original data in the name though so it was just a case of searching using PKS and 32.If the nagging gets really bad......Get a bigger shed:naughty:
...i2i trust me. What you see in the second picture is what I took out from the SD2.
If a similar PKS-DIGIPLAN called cd20 exists I totally disregard. But this is my chance so please educate me.
How many Amps drive is that cd20 capable to deliver. Probably the machine you took this from is a more powerful one compared to the little Orac.
And this was not the first time the SD2 needed to be dismantled for fixing. In the past, it blew a 40xxx series CMOS. The CD40106.
But today it looks a bit different because I have added DIP sockets for every single chip. and the appropriate sockets for transistor or diode in the PC boards.
