My upgraded system

Post by jscrow »

I just finished upgrading my system pictured below! I gutted one of my Racore expansion units and used the chassis to add a Gotek using a 3Flop board. The switch in front toggles the boot drive (up for Gotek/down for the 5.25). This system has the Tandy and PC-Sprint Mods installed (switches on the rear). Also, I installed a serial board in the modem slot that is connected to a wifi modem. As you can see, the sidecars are a jr-IDE and parallel port (modified bi-directional). Lastly, I added a Resound-jr Adlib card inside the Racore sidecar with an audio jack where the PC-jr switch used to be. Everything is powered using an PCjr ATX adapter (pico psu) which seems to be handling the load just fine, I'm sure I could add another sidecar without issue...

Really nice build!

I tried something similar with a 3.5” floppy as the second drive (an old IBM 720kb), but the pico psu seemed to become unstable and the computer kept freezing up. I guess the gotek draws less (or likely some other problem specific to my system).

Thanks!

I have the Gotek plugged directly into the pico psu and there have been no issues so far...
