Hi,
I might purchase some VAX boards for a good price, which I need
to negotiate first and I need some help with finding out if I
can use those in a VAX 6000-400 and/or -600 (XMI, VAXBI) machine.
Here goes the list and following are specific questions
T1010 DWBUA VAXBI-UNIBUS adapter (BI side)
T1022/1023 DRB32, VAXBI-DRB adapter and DR11-W adapter
T1031 KFBTA (AIE) BI RD Drive Controller
T1060 VAX 9000 PEM Module
T2020 XMI/NI controller
T2022/2023 KDM70 XMI-SI adapter pair
T2027 DEMFA XMI-FDDI controller
T2028-AA XMI-LSB adapter
T2029-AB XMI-SCSI adapter
T2036-AA KFSMA, XMI-DSSI adapter
T2080-YA CIXCD-AC XMI-CI adapter (for AXP and VAX 7k/10k)
The intriguing thing about this pile is that it's relatively
unusual hardware. I don't have this stuff yet and I don't get
it for free. If you want any of it, chime in and tell me what
you'd spend. I could make a bundle order that can give yet a
better basis for negotiation.
Detail:
T1010 DWBUA VAXBI-UNIBUS adapter (BI side)
- what cab-kit assembly is needed, is this something extremely
hard to find? Can you give a model number for the cab-kit so
I might find it somewhere?
- I might want that because I plan to have a UNIBUS cabinet
besides a VAX 11/780 in the near future. I could kind of
swap the Unibus between the two machines. And I could use
the UNIBUS frame buffer set that I might also get sometime.
T1022/1023 DRB32, VAXBI-DRB adapter and DR11-W adapter
T1031 KFBTA (AIE) BI RD Drive Controller
- what the heck are DRB bus and what are the accessories needed
to do anything useful with it?
- and what are RD drives? Old junk? Are those available?
How are they connected to the KFBTA?
T1060 VAX 9000 PEM Module
- there is actually a bunch of other 9000 modules. Anything
useful to do with this in a VAX 6000's BI bus?
T2020 XMI/NI controller
- is this an XMI ethernet controller? Can it be used in
an 6400 XMI bus? 6600? or only a 7000 and 10000?
T2022/2023 KDM70 XMI-SI adapter pair
- SI bus? Is this yet another disk/tape storage bus? Availability
of disks? Old or new? This isn't the same as SBI (11/780) or
SDI (KDB50) right?
T2027 DEMFA XMI-FDDI controller
- This should work on a 6400 XMI bus, right?
T2028-AA XMI-LSB adapter
- Laser bus? That's the 10000's bus, right? I assume that
would require a whole LSB backplane, power, etc. etc.,
not feasible with a VAX 6000.
T2029-AB XMI-SCSI adapter
- Just checking: are these -AA, -AB, etc. suffixes anything
that can make or break 6400 XMI compatibility?
T2036-AA KFSMA, XMI-DSSI adapter
- dito -AA -AB, etc. any issues there?
T2080-YA CIXCD-AC XMI-CI adapter (for AXP and VAX 7k/10k)
- dito. This sounds like a cool alternative for a faster
CI link than through the BI bus.
Your comments on any or all of the above are appreciated.
And let me know if your heart is longing for anything of
it and how much you would pay. (I don't make a profit from
this, I'm trying to get a good price on a bulk order.)
thanks,
-Gunther

T1010 DWBUA VAXBI-UNIBUS adapter (BI side)
Ooh! I need one of those. I have this 8200 here and two fried T1010
cards. They worked before the machine was moved here. I suspect
some sort of crimped cable or something. The same chip is damaged
and the same trace is *burned*, so it looks like unhealthy voltages
are present on the cables. That's easy to scope out, now that I know
not to just keep swapping tires until I find the flat. The first
was a fluke - the machine worked on the other side of town. The second
told me I have a serious problem (yes, I know, the _first_ one should
have told me that, but here we are).
T1010 DWBUA VAXBI-UNIBUS adapter (BI side)
- what cab-kit assembly is needed, is this something extremely
hard to find? Can you give a model number for the cab-kit so
I might find it somewhere?
I don't know what the cab kit's DEC part number is, but it's four
ribbon cables, a paddle card for the head of the Unibus and a Unibus
Exerciser/Terminator (not just a simple terminator). I know it's not
spec'ed for larger VAXen because of the latency between the
CPU and the Unibus when you have things like an XMI in the way. It
did work with NI machines and direct BI machines (like my 8200). I
do not recall what the largest/newest machine was that could take it.
I wouldn't pay more than $50 for just the card.
- I might want that because I plan to have a UNIBUS
cabinet
besides a VAX 11/780 in the near future. I could kind of
swap the Unibus between the two machines. And I could use
the UNIBUS frame buffer set that I might also get sometime.
- and what are RD drives? Old junk? Are those
available?
RD50 - ST506
RD51 - ST412
RD52 - Quantum 540?
RD53 - Micropolis 1335
RD54 - Maxtor XT2190
RD31 - ST225
RD32 - ST241-1
(there's a couple more I forget what they are).
Common on MicroVAXen, Rainbows, DECmates, and DEC Professional boxes
How are they connected to the KFBTA?
No idea.
