My student, Zach, has been working to debug why our bottom tape unit has been misbehaving. We are fairly certain that the issue is a short in the interface cable between the top and bottom units, because the problem appears on whatever unit is on the end of the daisy chain. Stay tuned. But in the process of monkeying with it, there was a period of time where they both worked just fine! #dec #pdp12 #pdp #retrocomputing #vintagecomputing #umdpdp12

@stefanhoeltgen Nice.

I've recently been playing with the ACSI2STM, having purchased it perhaps oddly for mainly Spectre Mac emulation, having just added an SM124 to the setup.

I soldered an UltraSatan connector to it last night to get it on a ribbon cable with proper DB19 connector into the DMA port (was having some stability issues before).

Is this device STM32-based?

Last weekend at #VCFe I once again encountered the meme that using original power supplies for your home computers of the 80s is bad because the line voltage was raised by 10% from 220 V to 240 V since then.

So instead of 5 V, as the story goes, they now deliver 10% more and would be outside the specs. But no, that's not how voltage regulators in power supplies work. They regulate voltage. That's their one job.
