Is the takeup leader (the plastic ribbon which is fastened to the internal reel) intact? Its outer end which grabs the tape from the cassette is arrow-shaped. Is the "arrow" quite in order? If not, the takeup leader should be replaced.
I have got a dead TK70 drive for that reason. Is there any source of replacement parts?

I think I have another copy somewhere. I'm suspecting that the TK50
drive in this external SCSI chassis might be bad...

Ian,
This is usually down to the tape rather than the drive.
It is recommended that you 'bake' old tapes before reading them - over
time they become 'sticky'. IIRC a couple of hours at around 50 degC.
I have a load of tapes that I need to read off but I've currently got no
way of baking. I suspect that a standard oven, even on it's lowest
setting, will be too hot - you need something like an incubating oven. I
know someone who used to do this on a regular occasion and had very few
failures using this method.
Regards, Mark.

You can also read a TK50 tape with a newer DLT drive like TZ85, TZ86 and TZ87.
As Mark said, the tapes tend to deteriorate even when stored in good conditions. It is recommended to retension the tapes at least once a year by winding it completely in and out. That recommendation is written in the tape manufacturers' preserving guide.
It will also prevent edge deterioration.

I started it to ask for opinions on rack mount intel servers to use as a base for mostly hecnet stuff.

If it's a quad core it's a core2 arch xeon. P4 (Pentium-D) only came in
dual core.
Gents... Fun as all the small talk is, this is getting a little much outside of hecnet stuff, isn't it?
Johnny
It's iffy... Since we're discussing a host where a SIMH-11 VAX might run with a HECnet connection.
Besides, Sampa started it. (Sorry about throwing you under the bus)

Johnny,
Could you please add node 4.245 ENGINE to Hecnet.
This is a 're-purposed ZX6000' - I bought an RX2600 motherboard and have swapped it into the ZX6000 case.
Regards, Mark.
