ПК-01 Львов (PC-01 Lviv): Part 4 - Where was I?
31About time I had another look at the PC-01 Lviv. I've managed to acquire three of them in total ... no idea if any work.
Also trying a 60fps video, hence the reduced 1080 resolution rather than the usual 4K. I could do 4K60 but I'd need to switch from iMovie ... ?
As they are 8080 (clone) based machines, they require ±5V and +12V to run, so aren't so simple to just power on and test. I also believe that they output inverted RGB ... not a big deal, you just need to run the RGB output through some inverters.
A summary of the three machines:
[1] Dated Sept 1989, precious-metal-containing parts removed for scrap, uses plastic EPROMs, all socketed
[2] My original - dated April 1991, all components intact, uses ceramic EPROMs, only one is socketed
[3] Dated July 1991, all components intact (uses western parts so safe from grubby little scrappers), uses plastic EPROMs, only one is socketed
I am hoping to get one complete machine working. The oldest machine will need all the decoupling capacitors replaced before it can be tested.
