Hi Gents, Can anyone tell me if the following are usable with simmons kits? 24 pin eeprom marked on top as follows AM27C256 -1500C 9629BPA 1986 AMD there are 30 of these being thrown out at work, which I have squirreled away pending your input. Thanks Pete

Hello Gent, you can basically use these on the SDS7 Hihat or Cymbal (32k) as sound eproms or on SDS1000 (4x8k quad sound eprom). Don't even think about promming these with EPB. Michael

Hi Gents,
Can anyone tell me if the following are usable with simmons kits?
24 pin eeprom
marked on top as follows
AM27C256
-1500C
9629BPA
1986 AMD
there are 30 of these being thrown out at work, which I have squirreled away pending your input.
Thanks
Pete

These are AMD CMOS chips, which require (to my knowledge) a higher voltage than the SPB can provide, to write to. They work fine when using a writer connected to a PC. I have downloaded several of the bin files from simmonsmuseum.com (thanks for those!), and they work perfectly fine on the CMOS chips you are referring to in an SDS7 or an SDS1, and maybe an SDS9. Personally, I haven't tested on an SDS9, seeing as I do not own one ( if anyone feels like donating to the cause, I would not be offended one bit :-P ). Of course you will need to erase them before you attempt to write to them, or you can see what they sound like first. Some sound really cool, some sound really spacey, and some just sound like ass. Hope this helps. Thomas --- In Simmons_Drums@yahoogroups.com, "p_k_daniels" <p_k_daniels@...> wrote:

There is no "SPB", you sure mean EPB, our good old bad Simmons Epromblower. This is operating with a programming voltage of more than 20V and will definitely "kill" any Eprom with a "C" in its name (27C256). By the way: The EPB was only suitable for 2764 and 27128 type Eproms. You can't playback 27256 in an SDS1, only 2764 and 27128. You can't playback 27256 in an SDS9, only 2764 and 27128. As I explained earlier, these Eproms are only good for use in SDS7 cymbal and hihat cards. Or as quad sound eprom for SDS1000. The programming voltage of them should be 12.5V. Michael

...and this is exactly why I just read this shit, and I don't post more than once every 4 years or so. When i first tried to write to a 27C256 with the "EPB", you are right, it did not work. Then I tried with the EPROM writer connected to my PC, and it worked like a charm. I cannot agree that it will definitely "kill" any Eprom with a "C" in its name (27C256), as you say, but then again, I'm not the expert, I'm just a small time owner of a few kits, which maybe one day I'll get around to posting pics of... And again, you are right, I was wrong. It was the 27C128 that worked in the SDS1. The current 27C256 in the snare channel of my SDS7 currently has a long(ish) burp sound, and works fairly well. Sounds wild through all of the filters and such...if you like that sort of thing. Maybe I'll put a demo video on youtube.
