Re: RL02 Spinup fails

It sounds silly but I don't actually have access to a Windows machine, but PD11GUI looks nice. I managed to boot into XXDP today using tu58em and ran the RLV12 controller test. It seems though that the version of XXDP I loaded does not support the 22bit address (17774400) and defaults to the

Re: RL02 Spinup fails

I have successfully built a rl02 disk using pdpgui on a windows XP laptop, the newer version works on window 10. All you need other than the software is a serial card like a m7800. Pdpgui acts as a gui. Do you have a m9312 rom/terminator card with a terminal console rom? Bill Degnan twitter:

Re: RL02 Spinup fails

I’m more used to working on HP drives of this type but it sounds to me like you are getting a seek Time Out. It sounds like the motor spins up to speed and the head load is being initiated. there should be a carriage unlock (I assume there’s a lock solenoid) and the carriage should start to

Re: RL02 Spinup fails

This can probably be ignored. I since realised it's almost definitely an issue with my terminator. Although, it doesn't matter how many times I build a terminator, it won't work. I based my terminator off Mark Blair's RL02 to USB project:
