Re: ACSI/DMA to SCSI Adapter
It would be cool if it supported the extended ICD command set so that drives larger than 1 GB could be used.

Re: Noob building a TF534
Out of curiosity: Where do you see a serial number? Afaik, 68030 are not individually serial-numbered. Apart from that, I agree that these are relabeled, like (mostly) everything you buy on eBay these days. On your photo it looks like the black paint might come off with a solvent, perhaps revealing ...

Re: UBESwitch Mk6 for sale
I ordered the PCB and parts required to produce about 50 UBESwitch devices. I currently have 5 up for sale on a popular auction site and will add more as I build and test them. I have modified the firmware to fix errors and remove some features that don't seem to work quite as expected. Isn't this ...

Re: Current postage chaos.
I laughed at the estimated delivery date since I thought that would be completely impossible. Much impressed. That's normal for UPS. Ever since the beginning of the pandemic we have to deliver to our Thunder/Storm/Lightning/Cloudy customers in the US via UPS. This is because for several months no p...

Re: TT no sound
The Microwire commands I referred to are only sent once after reset (while TOS boots). Meaning that you should see activity on data (pin 1), clock (pin 2) and enable (pin 3) of the LMC1992. I don't know the idle state of the data and clock signals afterwards, but enable should be high. EDIT: To clar...

Re: TT no sound
Also, I now looked into the TT schematic. The signal path is a bit more complex than what I recalled from memory in my previous post. PSG audio gets into the LMC1992 on pins 4 and 26. Assuming INPUT1 has been selected via Microwire, it comes out again on pins 8 and 22 to get mixed with DMA sound in ...

Re: TT no sound
Before considering replacing the LMC1992 you should check if it receives (correct) Microwire commands from the TT Sound Shifter. Iirc, the LMC1992 starts muted after power-up. Sound is enabled by TOS during boot by sending multiple Microwire commands. Microwire is an unidirectional serial protocol, ...

Re: TT no sound
Atarian Computing has good quality schematics for board revs. A & C: http://www.atariancomputing.com/downloads/schematics. Also dev-docs has multiple TT schematics ranging from badly scanned to high quality: https://docs.dev-docs.org/htm/search.php?find=_4 I would boot with no hard disk or floppy di...

Re: Picture Viewing.
Vision. Much more than just a picture viewer, but cool nonetheless. And still in active(!) development; in fact, iirc version 4.8 just came out about a week ago. According to the web site, it runs on every Atari with at least 1 MB of RAM: http://jlusetti.free.fr/visione.htm
