Just briefly and temporarily ... I've decided to go with a run of 15 instead of 10, therefore there are still 3 slots open.
PM me if you're still interested.

Absolutely ... while I'm slowly getting the feeling that my pace for the project is a bit slow, it's going nicely from a technical standpoint :)

Just ordered some straight SIMM slots for testing.
Also: All slots for the RC run are taken.

Of course :)
I can even include fitting 2x512k RAMs if you want (there's also support for 2x2MB, but my stock on those is quite low).

That would be nice!!

I still did not figure out why the ROM last time did not work..
they where flashed with right contents.
Maybe it had todo with the defective ultrasound chip ? :D
I will retry this time :)

I don't remember if we discussed this before; what were the symptoms of the ROM not working? What version of IWINIT did you have installed? Did you get any "Found ROM chip" messages when running iwinit -v?

Usually, as long as the ROM is reliable enough to read the header and verify the checksum, it will configure the registers for ROM support. It doesn't do any other validation of the ROM data, though you may get garbage/noise when trying to play MIDI files.

Simply no playback. except for digital sounds.

I don`t want to solder the dead bug back :) so i can not test output of iwinit
