Are you selling this?

Yes, in Cental Europe are people used to earn money for their hobbies selling different goodies:)

for people out  of Czech Republic I offer this only for Midiboxers, althought i have just few pieces, i give gentelman guarantie, that i plugged it in, let it boot and do iniciation routines that all parts are working.

Give me an offer i can not refusse:) I am not a thief.

Im seriously keen into make of it Midibox based Killing seq, but as my profesion is architecture, dont have knowledge to do it as MIOS system, i understand sh*t about coding PICs, so i can weld whot another one is able to develop.

it is not hard generally, becaus board of LCD buttons is assemled with IO parts, which seems to be a standart.

This things was made by Wyatt- A reuter company, classical 2 side PCB, no SMD parts except LCD Driver

Thanks for the offer pomics, but I’ve been off work sick for a long time and now I’m broke as a joke :frowning: It is a really interesting CS, even though I don’t know if the circuitry will be of use… I’m sure you’ll find a buyer soon :)  Hope it’s OK that I moved this to the fleamarket section, it should be easier to find now, and maybe a MB64 user will want one, who knows.

DrBunsen: Sorry man this killer flu BS has had me locked down … If it’s in the way, I can pay for a courier, otherwise I hope we can catch up soon :slight_smile:

No no, it’s not in the way, just trying to encourage you not to get further broke…

Oh thanks for lookin out for me bro! :smiley:

I wasn’t planning on buying this one (as much as I’d like to, just can’t afford it) just wanted to put it in the right spot :slight_smile:

the lost treasures of the old communist block …  :smiley:

Hello and Than…

time moved upwell almost ten years after

|studiing and reverse engeneering in LSI MSI electornic]

Im back with 4x4 and 4x16 LCD button.matrix to get alive.

still not shure hows LCD are driven,  originallz was all button board driven by Hitachi HD61830B

which workswell in both character so graphical mode.

LED s [2Y+2R each button] MM5451 LED Display Driver 2 or 4 each board are serial 36 bit TTL shift registers.

I have already maped buttons led, and im dump enoght to get

into  button LCD driving. If anybody interest do develop some

application, before I get into programing and logic analiding {other 5/10 years of live]

and get these things go, please leave a message.

Please respect my poor ability understand well these things,

but I m wondering about ading 4 to 16 encoderes,

some track, layer, edit, perform, menu, enter {SET},exit,{RESET] shift, alt, up, down

PLAY, TEMPO, DIVIDE, STOP, CS butons

and realise some graphical SEQ 4BLM version,

focused to work similary to SEQ 24

 

more edit and data soon

Pom
