Some build pics of the 204r.
These aren't official... just my working 'notes' to help trouble shoot.
It's not a Buchla Module, but should be compatible with most Buchla modules.
It follows the same size, format, etc. As for the circuits used .... I don't know.
Microcontrollers like the one used in this module certainly weren't around in Don's day
IC headers, caps, resistors, etc
i found these on ebay
Amtel 8-bit Microcontroller - MCU 20MHz Ind. Grade
There are 14 pins
I have an Olimex avr programmer so might try that first

The Olimex has a 6 pin & 10 pin ribbon cable
(In Circuit Serial Programmer)
I'll be flashing the chip via the ICSP 10 connector. Pin 1 can be identified with an arrow and the red stripe
I'll program this chip using a breadboard.

Thanks for sharing. I'm a fan of your website. As for Roman's clones, I have mixed feelings. I've built some that work perfectly, but it seems like half of them have issues. Although at first he started making his clones like the originals, he now seems to be making look alike modules that contain no Buchla circuitry. I've seen pics of original 204's and they had numerous hand-built vactrols in them. Unfortunately, I see no vactrols in this module. I suppose he went with the microcontrollers instead, but hey this is like buying a VW that looks like a Jaguar.
ReplyDeleteI still have to figure out why mine doesn't work. Maybe the programming didn't go well.
