  1. Hi,

    I started 8 year ago a Midibox Sid V2, but it was sleeping (kids, lots of other things of life, ..)

    After successfully building some core modules in 2014, I finally decided to switch to a MB6582 in order to have a cleaner finish.

    The PCB from Modular Addict is at home, the panels are on going from UK, and I am checking the BOMs in order to acquire the missing material.

    8 x 6581 and 8 x 8580 modules are waiting. I will use an original C64 PSU.

    I hope I will finish it for the end of the year.

    If someone is interested, I can sell the finished or unfinished the MBHP modules I have (4 CORE, 4 SID, some DIN and DOUT, don't remember how much)

    So I'm back.

  4. Since I've got a C64, I have one more question : I see there is a large voltage conversion circuit on the right of the C64 motherboard, with even a 7805. Does it mean I need to stabilize the 5VDC or is that 7805 there only to be sure the voltage is stable ?

  5. Update: I got a C64 today, but its SID is dead : 1 voice produice a constant 440Hz sound... I swapped that SID with one other, and the sound is OK... so I need to get an other SID. I see there is one left in the Flearmarket :)

  6. Hello,

     

    I will get a brown C64 today, which will complete my set of 4xcores, 4x6581 and 4x8580.

     

    I will use the optimized PSU set-up, and some things are not yet clear for me:

    - the 7805 are dropped because the PSU provides stable 5V

    - there is a 7809 to stabilize the 9VAC output, and combined with the 5VAC output, it provides 5VDC and 14VDC

    - the "Optimized PSU" document don't mention the MBHP_SID 78xx : do I need to put one 78xx by MBHP_SID, or can I use one 7809 for the 8580, then link the power to the three others, and the same for the 7812, or is it better to have all MBHP_SID their own 78xx to avoid ground loops?

     

    Kind regards,

    Xavier.

  7. In stand-by due to vacations, but the current status is

    - 4 MBHP_CORE working

    - 8 MBHP_SID and all MBHP_DIN and MBHP_DOUT soldered

     

    To do:

    - put cables betweel all of that

    - build a power supply (there I still have a LOT of questions)

    - build the control surface
