how good is the data reliability with CD ROM and DVD RAM?

by carlojpisani＠gmail.com

hi yesterday I was shocked by a couple of videos on Youtube where guys pointed out their negative experiences with CD ROM and DVD RAM as media for their own backup. They complained their data completely lost after 5 years of storage in CD ROMs, pointing out that their CDs were perfectly conserved and kept clean without scratches, but all the data is gone lost since the media is unreadable. This is what they said in the video. I have a lot of backup here stored in CDs, and I have recently bought an SCSI DVDRAM unit to create new backups in caddies DVD-RAMs (of 4.2Gbyte each) what is your experience?

Troubleshooting HP 2116B

by cc＠informatik.uni-stuttgart.de

Ok, so I've got the computer almost running now. I now need to fix both sense amplifier cards. One (0..4k) sometimes reads a one for bit 3 after the machine has warmed up. The other (4..8k) has a stuck one for bit 7. Swapping these cards make the errors move to the other core bank respectively. I have the newer cards, 02116-6298, not the older 02115-6001 The latter has CA3028A used as sense amplifiers. My card uses HP 1820-0183 (metal can IC from RCA). I guess that it is also a CA3028A or maybe a CA3053. Can anyone confirm this? Next, the manual on bitsavers (02116-9153_2116B_Vol2_Oct70, and the same as found on the hpmuseum site) not only contains some errors (see my other post about the front panel lamps). It has also some badly scanned pages with parts missing, notably page 5-50 (PDF page 350) lacks the right part of the page. Is there a better scan available? My 1968 copy does not list the 02116-6298. Christian
