Bare SID Boards Benchtested succesfully - 4x good chips.


Recommended Posts

Well... 4 sids have been benchtested with the 1khz test program.. working ok so far ..and sidplay is feeding the High voltage sid music collection through one of them ok right now. Which is nice to hear after all these years.. without a massive tapeload time  :)

However the main sid program is giving me some fun right now ...having trouble loading the bank presets into it.. they appear to send in two of the apps used ..and then on use the presets appear to be empty. will try another program or two to upload the data.. i seem to recall having similar fun with the mbfm...

Also...

really like these winstar lcds iv'e got hold of recently.. sharp, clear & are sold as inverted blue... however come out as a really lush purple tinged blue - with the text coming up as a pale blue/grey.

What supprises me.. is some really awful quality lcds have been built into alot of commercial equipment in the past (false economy corner cutting...) ...yet the quality of whats generally available these days is quite good indeed :)

Note: the board parts, lcds & backlights (to an extent) that Winstar & Crystalfontz use are interchangeable/compatable for the most part. I had to fix a display n' do some part switching :) Either they used the same reference designs ..or they source certain parts from the same people (or C.F. buys W.S. OEM Parts).. I found it particularly curious that both pcbs had -identical- trace patterns.

Hi!

Man - where did You get those LCDs? Got couple of spare willing to sell? ;D IF the picture is even nearly close to the truth about the looks, these are beauties and would match so called UV leds (more like purple actually) I've got.

And for the PCBs being the same - It's probably this China thingy.. as HD44780 and it's clones are standard for the character LCDs, there's a reason to produce million base PCBs that can be used by various manufacturers or maybe these LCD are all chinese origin just branded differently...

With regards to those uV LED's, although their output is rather low there has been some concern in the DIY stompbox community that they can cause damage to the eye. While I don't have any particular expertise in the field, I wouldn't want a control surface stuffed with these things right in front of my face!

Thank You for Your concern!

Aren't these stombox guys the same peepz who have endless arguments over different 4558s and never care to look at the actual waveform pictures at the scope to see if there's really any difference? Same guys with nice suntan on the summertime?

[/sarcasm]

UV radiation has been studied long enough to know the harmful effects on different wavelenghts - my leds have such a wavelenght it's not harmful. Period. These days you don't need to KNOW these things, but combine information available from various sources.

p.s. Aww -  I'll have to take some words back.. I do have old JRC4558s in my drawer, those DEFINITELY sound the BEST in Tubescreamers, whatever scope shows 8)
