Jim,
Thank you Sir for your advice with this 1581 IEC buffer Fix. I'll do
some more testing with the drive before going down the
Desoldering/Soldering of IC's rabbit hole. Unfortunately I have Cerebral
Palsy with some mobility issues that affects my arm/hands (I have one good
hand to work with) Desoldering/Soldering has always been a challenge.
However, I'm only a 30 minute drive to VCF East HQ at InfoAge in Wall, NJ
to get some assistance with a Desoldering/Soldering expert at one point, if
needed.
Also, Thank you for the update on the RETRO Innovations Shipping Delays. I
was not aware until now. No worries. I hope COCOfest was good this past
weekend.
Bryan,
Very good observation on your part. My initial testing was done with a HD
disk, not a DS/DD( it was all I had on hand over the weekend/ I could not
remember what the 1581 drive actually took.) I need to find my box of DS/DD
disks from my Zenith Data Systems SuperSport laptop to do more additional
testing with the 1581. Thank you for the clarification on the correct disk
type for the 1581. Funny thing is both the c64c and the c128 formatted the
HD disk in the 1581 drive without any complaining it was wrong.
Take Care,
Russell LeChard
