Re: Re: Reviving K2000 software development

I'm pretty sure that power cycles will not keep sampling RAM . Sample ram is not backed up by battery. The headers stay but that's it.   The batteries are for program RAM & also I've seen (looked thru) several times that Incomplete service manual Your right its like they were working on the manual & it was never finished.   On E-Bay You might find the sister board - orch chip & the if memory serves my the contemporary chip Rom sound & set-upsOn Wed, 2/20/19, [email protected] [KurzList] <[email protected]> wrote:

       Hey Bill,
 thanx
 for you answer and support.
 Am I reading right that your K2VX is
 keeping the contents of the sample memory after a power
 off/power on cycle? That would mean a lot. Incidentally, I
 read in a datasheet this morning that some DRAM chips do
 have a battery back-up feature. From there to having a
 battery-backed sample RAM, there may be quite a long path;
 but the one who never dreams and hopes seldom goes and find
 new territory.
 Regarding VAST programmer: do you
 have the source code? What are your projects regarding
 it?
 I have not found
 any ROM for the K2000 on Kurzweil's website. If there
 are any, I would be very interested. Actually, even just the
 release dates and release notes of the ROMs would be of no
 little interest to me!
 I thought the latest version
 released of the OS ROM was 3.87 in 99; if YC sent you
 something in 2001, it must have been the latest also; hence
 your mentioning that you got a new EPROM is startling to me.
 Any newer than 3.87?
 Yann
