So far I have been getting BA6110FS datasheets. However, it is ok, if BA6110 is rare but BA6110FS with same values is still mass produced I will use that in the Mod.

I am also looking for alternatives to replace the old transistors and J-Fets.
look at the sticky thread in the making x0x forum about substitutes, though they are likely to change the sound

Hmm. I might do a test kit version of this machine so I can test component variations.

For now I can say there will be switches to route alternatives.

Questions about the Atmel.

Question1.
Atmel pins number 12 (PD2) and 12 (PD3) seem to be free and has no use so...
I was thinking if anyone could tell me if it is possible to use these 2 pins to control 7 segment display to show the
tempo in the memory.

For this I was thinking to use two of the 47HC595N to decode the number to ELT511GWA 7segment display.

Question2.
I also need one Pin for the " Clear Pattern " command.
Hopefully it is possible with the pin number 2 ( PB1 )

it should be ok to use those pins

if you are going to use the shift registers
you will need another pin to latch the data

I was thinking to use 12 to LATCH and 13 to shift data.

How many pins actually needed? 2 or more?

Maybe using BCD decoders
SN54/74LS48 could be other option,
however I still need the s-registers to give the correct code.

you need three for the shift registers
data clock and latch

there is a third pin open
or you could piggyback off the current shift register latch

I have also been thinking of adding three 7-segment displays for showing the tempo.

However, my plan was to use the tempo that gets spit out from the DIN sync port. It shouldn't be that hard to use a counter and a couple of LED drivers for that... but I haven't thought about it that much, I use a CR-8000 now slaved to them to show me the tempo. :)

Two types of solution.

Anyone interested of helping me out with software or bug search please contact me to [email protected] ( Public Email. You can google it as well. )

The board layout should be finished, but I don't count on it yet. I have to be absolutely sure it is not blowing up fuses somwhere before I release it.
