Microdrives dont spin or do anything

Postby retro_collector » Wed Aug 14, 2019 7:31 pm

Fixed my keyboard problem with new membrane but when I press F1 or F2 the QL launches but the micro drives do nothing and if I do DIR MDV1_ or 2 nothing happens and get error message "NOT FOUND


Also the VdriveQL the green LED lights but when you try to load and run BOOT you get "NOT FOUND" so it appears the Microdrive bus is an issue

Any ideas what to look for or check?

Help greatly appreciated!

Cheers!

Bill

It sounds as though mdv1 may not be plugged into the motherboard properly - those 18 wire pins on the two flexible cables are a nightmare...

If mdv1_ is not properly connected, then mdv2_ and the vdrive will not work either...

Do you have the vMap (to allow the vDrive to work as mdv1_ )?

Hi Rich,

Yes I do. Charlie told me to install it so that's next. I will post once I have it installed

Cheers!

Hi Bill. As Rich has mentioned mdv1_ may be unplugged or faulty (or the 8302 ULA may be faulty -SellMyRetro still has spares). Best to just install the vMap as this provides independent addressing for the internal drives and the external bus. You'll be having to open the QL anyway so may as well install the vMap while you're there :-).

Installed VMAP, did DIR MDV_3 it worked,  did LRUN MDV3_BOOT, it executed, did HELP, listed all the commands, did VINFO , now I can't access the drive anymore. I do LRUN MDV3_BOOT and the YELLOW LED TURNS RED and get not found.

I tried MDV1 and MDV2 before and MDV1_ LED doesn’t light and motor never spins, MDV2 DIR LED lights and motor spins but get NOT FOUND message

Should I beat my head against the wall?

Thanks!

Bill
