[comp.sys.cbm] 1581 JE1 AND JE2 SERIES

richard.gervais@canremote.uucp (RICHARD GERVAIS) (04/03/89)

Hi,
I have recently bought a pair of 1581 drives for use with my C128. The
serial numbers start in JE1 and JE2 and the manufacture date is March
1988. The drives have a 312558-02 and 318045-01 set of chips for the
controller and ROM. Your test program I got from QLink tells me I have a
1772 controller, but I do not know if I have the most recent ROM
version. Could you tell me what is the most recent part numbers. 
 
One of my friends who runs a BBS on a C128 tells me he has chips
312558-02 and 310651-02. Is this set more recent?
 
The same person is telling me and I quote "the U10 chip solder causes a
'DRIVE NOT READY' error". It seems the 1581 are prone to this condition.
Is there a preventive measure or a cure for this error.
 
Thank you for your assistance.
 
Richard Gervais
