This definitely sucks :angry:

What case do you purpose to use for this? I think the mb808 uses the Hammond 1456. The version with wooden sides looks pretty nice

In the PDF you linked it says: It can be powered with +/-9 to +/-15 volts.

I am by no means an expert on this matter. But i tested my own SIDs last week with a SammichSID i borrowed from a collegue. You can sometimes hear some minute differences in volume levels between different 8580. However i have a 6581R3 and a 6581R4 and the volume level on one of those (can't remember which one) is a lot lower.

I assume you mean acid 64? I couldn't get it to work either. I put the .dll in the same directory but it doesn't see any devices.

I couldn't get it to play nice with a SammichSID and GM5 module. But since the Sammich was a loaner i didn't put to much effort in it. ASID was working fine.

I believe nILS made a patched hardsid.dll for Acid C64 Player. Unfortunately that doesn't seem to be working with the latest version. Not sure what version does work.:shifty:

I am still interested as well.

Very nice indeed. Did you convert a Hammond Mfg alu housing for that? or is it an generic black anodized aluminium profile?

Is the DIN Sync still functional?

Pin12 (TST2) is not connected. Pin2 is. Like Wilba said, don't forget its upside down.

The datasheet, recommends using Panasonic HFQ (replaced with FC)series, Nichicon PL, Sanyo MV-GX or equivalent elcos. The recommended tantalums are hard to get and atleast here only available through mouser or digikey.

It will be faster and not much more expensive i am guessing. Not sure about the last bit, but way sure on the first. I know your MB6582 has been covered on quite a lot of dust, so i think it would be a good idea to just order a psu. If you check the datasheets of LM2675 and LM2676 its not that complex. If you download the program LM267X Made Simple it will even calculate all the components. I checked if it was correct according to the formulas in the datasheet. And what do you know, it is correct :shifty: The problem is most components recommended are SMD. I looked for through hole stuff at reichelt....and still ended up with smd. For the caps you need low esr parts which are a bit more expensive.

The heat is probably not a problem. As the load is pretty low. But i figured will i was at it, make the whole thing completely switched. At 1A max it produces so little heat, it comes in a DIP8 or similar smd package. The pcb is very small if you go by the ref. design national semi gives you in the datasheet. The bigger 3A brother comes in a TO220 package but can be cooled with a small TO220 heatsink.

I have ordered a LM2675 for the 9V and a LM2676 for the 5V part. Since they are 90% efficient i don't expect much heat. Component choice is a bit more tricky then with a linear one though.

I am going to build a Switching PSU which uses 260kHz frequency. For modern switchers its even possible to do higher frequencies. 1mHz is achievable.

The 45-15 one is a bad idea. According to the datasheet it needs active cooling. Looking at the datasheet it does looks like a dated design. Estimated Efficiency at full load is min 65%. Which isn't very high. Could very well be that the switching frequency is quite low. But can't find what it is. At the distributor you pay only 18.75 euro for the t-40 meanwell. Downside is they only sell to companies.

I don't see why not. You just need to lookup the midi implementation chart. A midibox 64 would do the trick.

Display sells the t40 one for something like 34 euro. Couldn't find a local supplier for the t30.

A couple of weekends have passed. But only today i had a chance to look into it. Currently figuring out how to hook this thing up. Firstly trying to do 8bit parallel. The tft board connector looks like this: The datasheet says these pins need to be connected for 8bit operation: nCS (Chip Select Signal) RS (Register Select Signal) nWR (Write Strobe Signal) nRD (Read Data) DB[17:9] The unused DB[8:0] pins must be tied to either Vcc or AGND. The driver also mentions a nRstPin and a Lcd_LightPin. So i am assuming nRESET and LE EN need to be hookup as well. Update: nCS should be connected to DGND if not used.(Low: the ILI9320 is selected and accessible) RS can be tied to RS (duh :tongue:) nWR to R/W? nRD dont use? nRESET i assume should be either high or left floating. EN should probably be high, so the backlight will be on (always).

Silly me, i thought that unregulated implied an AC adapter.

If it has a polarity switch i think it's safe to say its regulated.

So many questions and so little answers :ike: My first and probably last question for you is.....WHY? You say less sensitive to falling. I don't see how 5 stacked PCB of 400x100mm can be less sensitive then 3 tiny IC. More silly questions, soak the whole thing in water.....You must have been high when you wrote this topic :pinch:
