Hi Alan, You don't want to try to repair the controller? There are some custom IC's on there (it appears) but is largely off-the-shelf TTL... I'm sure someone on the list has a lot of experience with these and could repair it or help. -- Pete Rittwage On Tue, Apr 3, 2018 at 00:50, Alan Frisbie via cctech wrote: Several days ago I wrote about my joy of finding a TDL-12 disk controller, emulating four DEC RL02 drives and using a SCSI drive. Sadly, I discovered that the controller is a dead as a doornail. It doesn't respond to any bus address at all.
So, I'm back to my original quest: I need a controller that emulates the DEC RLV11/RLV12 and RL01/RL02 drives. From my Google searching, I see a couple that use SD or similar solid state devices. Does anyone here have any direct experience (good or bad) with any of these emulators? I don't mind spending money for a good solution. Thanks, Alan Frisbie
