a bit off topic - looking for someone w/7 track 1/2" analog

comp for 1 - 7/8 IPS like to get all tracks digitized https://photos.app.goo.gl/IMcgjxugzKMuIvKv2 will put on open file server then sell the tape -pete

Speaking of tapes and good ideas, but...

During my browsing, I've run across mention of the Emerson "Tape Pac" 2000 series, a half-inch cartridge tape system targeted at minicomputers, and it seems, the PDP-11. Here's a mention in IEEE Computer, about the new products at the 1976 NCC:

800 and 1600bpi 9 track test data

There are two gzip'ed files up now of analog digitized 9 track data under http://bitsavers.org/projects/9track containing two files of 16 bit incrementing data patterns blocked 512 bytes/blk and the tach signal from a Qualstar 1260 running at 50 ips. The data can be viewed using Salea's Logic

RE: AlphaServers

I seem to remember issues with Alpha's even when new. I was asked to help out somewhere running VMS on Alpha and we had a couple of failures on the CPUs over the few months I was there... .. contrast this with working on IBM xServers and we had over 100 servers and only ever had failures on

If anyone is in or near Portland Oregon and interested, they are available. There are also at least 2 x 14 drive SCSI arrays, cables, etc. At one time I was offered a 5 rack fully redundant Alpha setup based on 3 40's or 45's Two servers were running with one is hot standby, the 3rd was a cold

Re: AlphaServers

So, B-Cache is a common failure; any idea what specifically is failing about it? I've got a 1000A, but its been years since I've tried booting it. It was successfully booting when I last tried it, however. I think I've got Tru64 installation media somewhere around here, too... Kyle

An interesting discussion, especially considering the stuff usually spoken in comp.os.vms regardiong the viability of X86 boxes. I have had 3 Alphas.  Two of the office refrigerator sized boxes and one of the PC Tower sized boxes.  All three have died.  In the meantime I have X86 based boxes that
