Dave, The Univac 1219 tapes are: 7 track/ 556 bits per inch/ redundant format (3 data bits written twice across the head)/ Modulus 3 (three 6 bit data words transmitted to the computer as one 18 bit word. Also have a few 1218 NTDS tapes that I think were 200 bpi/ non redundant. I don't know of anyone with an operational 7 track machine. We don't want to place those tapes on the drive unless we have the machine up to the point we can copy tapes. My wife cant be left alone so I can't come up now. Might be a chance in the spring if I can get her daughter to stay long enough. Duane On 1/27/2023 11:41 AM, Dave McGuire via vcf-midatlantic wrote:

I welcome a bit of illumination to help me form a vision of the totality of the problems. On the tape subject, one practical need I'd like to crack this year is archiving the UNIVAC 1219 tapes. Lets start a new thread on tapes if anyone has more to offer at this time.
We do a lot of tape archiving at LSSM, and can help with some of this.
Are the Univac's tapes 7-track, or 9?
