appreciate the reply, Matt! unfortunately it doesn’t seem that that did the 
trick, another round of feeding it disk images and it still doesn’t want to 
boot.

i tried the block and sector RX50 images on the dbit[.]com archive both as-is 
and converted to IBM MFM raw and HxC formats, and the teledisk images on 
ibiblio[.]org converted to the same.

my img.cfg:

[rx50]
cyls = 80
heads = 1
secs = 10
interleave = 2
bps = 512
id = 1
rpm = 300
rate = 250
mode = mfm
iam = no

should i start suspecting my gotek (or worse, the system board) or is it still 
possible that i’m at fault?

Got interesting stuff to sell? Let me know!
Looking for DEC, IBM, CDC, SGI, Data General, and more!
