Cheers,

Yeah, you need this as it's reasonably quiet even with this. When inside the case and the speaker's glued to it the case acts as a sound box and it's about the same volume as the original microdrive, which isn't loud.

Re: Video: Sinclair QL Upgrades (PSU and vDrive mostly)

I was really surprised that the ATtiny85 based sound board being sold was so awful given it came after the one I made and published the complete design and code for. I've just seen (and listened to) your video: very ingenious! Do you think it would be feasible to add also the typical "microdri...

Re: Today I Received...

That's a treasure trovel.

Those 68030s would be useful for Atari/Amiga accelerators with a QFP adapter board.

Re: SMSQ/2 on Atari

Well, I'd have very much doubted it would have worked on the TT given the very different stack frame (68030) and a lot of the hardware, especially on the graphics side, being very different for a bare metal kernel to control.

Re: SMSQ/2 on Atari

Hi, Thank you for tge information, but why does the QLE.WIN file attached to SCSI 0 in the Hatari Disk setup only read and boot up when the System is set to TT, rather any other option on the system option. Well, none of the others had the SCSI chip so it wouldn't be emulated in Hatari. You'd need ...

Re: SMSQ/2 on Atari

This driver is built into the TT, which is probably why the emulator recognises, the QWA file on the SCSI hard disk option. That's actually not true. The TT's ROM only has enough intelligence to scan the SCSI bus (as it does the ACSI bus, which is a simplified version of SCSI) and read the boot sec...

Re: My ZX81's stopped working. :-(

Yeah, pity about the vLA81 though. I've no idea why it went phut. There are no mods to the machine, not even composite video output so there shouldn't have been any way that it was overstressed electrically. I didn't even have the RAM pack installed at the time as I was just trying to tune the LCD T...
