Has anyone ever gotten a "TK50-Z" in a 'TK SCSI' encosure to work with
any
'normal' scsi controller on a PC or something? I picked one up for a few
$$ today, and just realized the enclosure has a 220V power supply...
Also, how do I get the disk out of an RRD40 without a computer attached?
If anyone's interested in this stuff, reply off-list:
DEC RRD40. I don't have anything but the drive and whatever is stuck in
the drive with the CD in it. In a 110V external enclosure.
DEC TK50-Z. In a 220V external enclosure (IEC power connection)
DEC RZ55. In a 220V external enclosure (same one as TK50-Z)
DEC DEBET. 110V/220V switchable ethernet 'bridge' I think.
PowerMac 6100/66
PowerMac 7100/66
PowerMac 7100/66 'chipped' to 80MHz
- i don't know the specs off the top of my head for these, will have to
look. mostly 250M-500M hard drive and 8M-24M of RAM
Quadra 660av
Quadra 610
Mac IIci
Mac SE
Sun SparcStation 1
- 40M RAM, 240M HDD, CG3 video
Sun Sparc IPC
- 40M RAM (IIRC, will check), NO HDD, builtin video
2xNCD 19r XTerm, upgraded memory. One with AUI/10B2, one with AUI/10BT.
2xIBM 3191 terminal (going on EBay if I cant find a buyer this time
around)
2xApple //e, one with 128K and DuoDisk, one with 64K and single Disk ][.

Yes, but not me. IIRC, it needs to be a TK50Z-GA. Keep in mind the drive
is only 95MB, so is really only of use if you've got DEC HW.
Also, how do I get the disk out of an RRD40 without a
computer attached?
Um, unless you've got the 'clear sleave', I don't think you're going
to get
the disk out without demolishing the drive! As long as that's the drive I'm
thinking of it uses a funky 'pincer' holder for the CD, with a clear
'sleave' around it to make up the 'caddy'. You stick the caddy in the
drive
and pull the 'sleave' back out. To remove the CD, you stick the 'sleave'
in
and pull out the whole caddy. (hopefully that makes sense)
DEC RRD40. I don't have anything but the drive
and whatever is stuck in
the drive with the CD in it. In a 110V external enclosure.
Any idea if this is a SCSI drive? There are two varients of this, one is
SCSI, the other connects to a Q-Bus controller.

How easy is it to take apart without killing the drive? Or can I make a
'clear sleve' very easily out of a couple of pieces of plastic?
It's got a pair of 50pin amphenols on the back, and a circuit board inside
between the connectors and the drive. So, it looks like it's SCSI.

I've no idea how easy it would be, I've never tried to take my drive apart.
As for making a 'sleave', I don't think you could without one to go by (even
then I'm not sure). The worst part is the caddies for this drive are rare
as hens teeth!

Oh, well. I'm sort of looking for one that will work with the Q-Bus board,
but not very hard.

I don't know about making a clear sleave since I haven't seen a whole
caddy yet. I bought a drive off of Ebay, and it had a disk still in it,
like yours. I was able to take the top off of the bare drive and pull
the cd out. I think I pulled them out separately, but am not sure on
the order.
I don't have the drive anymore, so I can't look at it to remind myself.

NetBBSD/PC-DOS PC, to make tapes from some images. I got the -GA off
eBay for about $5. The shipping whupped me stupid, but it was worth
it.

Yup, got a stripped one sat on a desk at the moment ;
TK50 (ver E4) from a different system
the SCSI-TK50 drive adaptor board from the (scrap) enclosure, set to ID5
PC AT PSU to drive the adapter board & TK50 drive
PC with Adaptec AHA1540CF, running DOS6.22 & Adaptecs DOS driver
(ASPI4DOS.SYS) loaded.
Using the ST program (v1.1, by John Wilson) I can read & write images from/to
TK50 catridges happily.
I have the thing nekkid as I need to clean the TK50s head using a Qtip with
IPA on every few tapes I play with as they get gunked up from reading the old
tapes quite quickly.
Now, if someone happens to have an image of the Mvax-II full diagnostics that
could be usefull...
