I've heard its possible to "upgrade" a uVAX II to a uVAX III by replacing
the KA-630 with the KA-650 CPU. Now I've looked at a KA-650 and it has a
metal cover over its end and a small RJ-xx like plug in it. The KA-630 has
two IDC connectors that go to the 630CNF console plug in the BA123 world
box. Do I also need a conversion kit for the KA-650 or is the CPU with
connectors hiding behind this metal facade?

If you try to use the BA123 again, simply use the 630 cnf console. If you
remove the metal cover from the ka650, you see the flat ribbon connectors
for it.
I use here some of my KA650 in BA23 & BA123 enclosures.

The boards are identical. The difference is in the firmware. If Emanuel's
information about an SC02/L is correct, then there at least *four*
versions, because:
SC02/A RP11 emulation, compatible with RP02/3 disks
SC02/B RH11 emulation, compatible with RM02/3 disks
SC02/C RK611 emulation, compatible with RK06/7 disks
These are the only ones I've seen in Emulex docs. There are similar
versions of the SC03, which also has a /MS variant, which supports MSCP. I
assume there are similar variants of the SC12, which is the Unibus version.
However, the original enquiry was about a SCO210101-CXL, which is an
SC02/C.
Dan was correct.

Hi all,
I went scrounging today and found some interesting cards. A picture of
the first one is at "http://www.intellistar.net/~rigdonj/card1.jpg" and a
picture of the second is at "http://www.intellistar.net/~rigdonj/card2.jpg".
The first one is interesting because it has a list on the right side that
appears to be a list of memory locations and op codes. It's hard to see in
the photo but the first column is labeled CNT. (count?). Most of the ICs
are dated 1972. The only other markings on the card is "TERADYNE A 794" and
"Made in USA".
The second one is a core memory board that I *think* may be for a Data
General computer. I picked up several of these and they're all made by
Dataram Corporation and appear to date from 1972. Their part number is
3010290. I took the cover off of one. Man, the cores in these are tiny!
Can anyone identify them?

I seem to remember that the connector is similar (maybe identical) to the
Diablo Model 30 connector, which I do have the pinout of. I can post that
if it would help.
One thing I certainly remember is that it used 1-of-n selects (like an
RK02/Diablo model 30) and that it could only be linked directly to an
RK11-C controller. There was a Plessey paddleboard that went into the
drive connector slot on an RK11-D and had a decoder chip (at least, maybe
some other simple logic) on it to sort this out.

I would certainly appreciate the Diablo pinout - if the pin layout is the
same, I would expect the signals to be the same , at least something easier
to check stan starting from nothing !
Thanks

If I were in your position, I'd try to get mechanically good cassettes
rather than worrying about acoustically good tape. What's most likely to
happen is that, over time cassette tape will lose chunks of emulsion from
its mylar backing, or the mechanical parts will break or jam causing damage
to the tape. The audio demands for computer use are not very stringent.

We have 7900's (about 20) in use on test systems still. We also have 7905's and 7906's. I maintain them. The platter package that goes in the 7900 is not the same as for the 7905/6 models. The outside casing looks the same, but the platter for the 7905/6 is about twice as thick as the one for the 7900 drive. Plus, the disk pack for the 7900 Drive has 24 hard sectors as indicated on the bottom of the platter. The 7905/6 disc pack has one notch on the center hub which is used for a soft sector configuration. Do not put the 7900 disc pack in the 7905/6 or vice versa.
Michael Morar
PS - I need some info on the A2 board of the HP-7900A disc drive. The A2 board has special solder terminals mounted on the board for connectors J1 and J4 thru J7. I need to find out who makes them. HP no longer has any info on the drive, and our service manual does not have a break down of these pins.

I finally borrowed a digital camera to photograph the damage to my PDP-8/L
parity core stack. The damage is more extensive than I remember. There
are the two main areas, but in addition, there are single bits that are
missing here and there over the entire area. I do not think it is possible
to repair this board without rewiring at least the four core mats on this
PCB in toto... that's 128x128 cores for the folks keeping score at home. The
wire density is approx 32 per inch. Much work. I won't be doing this anytime
soon.
Here's some photos of that stack I got back in '82 with a partial PDP-8/L

Correction, directly from the manual. RL01 or RL02 emulation ;-))
But serious, there are two version of the SC02 board. The SC02/L emulates
the Rl01/Rl02 disks, and the SC02/C emulates the RK06/RK07 disks.
Looks to me, that the big difference is in software, because both of these
boards look very similar.

Well, technically the Eagle is a 10.5" disk. Other Fujitsus, like
the 2284, are really 14" (and they have a nice transparent cover
over the HDA so you can see the disks spin and the heads seek...)

Most 5.25" SMD drives are rather modern and have data rates too high for
the older Emulex (and other brand) SMD controllers. Newer Emulex
SMD controllers, like the QD33 and QD34, don't have a problem with
the high-data-rate SMD drives.

The disks you are looking for are SMD disks - 60 pin digital cable for all
drives, 26-pin data cable for each drive. Yours must support two physical
units.
I have used 14" (RA-81-sized) disks like the Fujitsu Eagle and have seen 5.25"
disks, but never used them. I know that SMD disks are available in the 600Mb
range. I don't know how small they get. I can't imagine how you'd map
hundreds of megabytes into several dozen RL02 images, but in the interest of
compatibility, I guess they'd have to do it.
On VAXen and PDP-11's, I've always used a Systems Industries 9900 controller
to attach Fuji Eagles (and some other sizes) to the Massbus. I have an SI
Q-bus controller that appears to talk to the 9900 (dual 40-pin connectors),
but I've never used it. I have KDA-50's now (and wish I had docs for the
CS-21 SCSI card).
Bottom line - SMD disks are hard to find, but they are out there.

The SC02 is a Qbus SMD controller. The SC12 is the Unibus version. I

This is an SMD drive controller. Is it a hex-height card or a quad? All
my SC02s are quad-height Q-Bus controllers.
An SC02 can handle two physical SMD drives. BTW, I think you mean one
60-pin and two 26-pin (not 36) connectors. There are several versions of
the firmware for SC02s, emulating different DEC drives. I don't have my
manuals to hand, but IIRC the -C version emulates RK06/7. Depending on the
size of the attached physical drive(s), it will emulate several logical
drives. You might find a manual at
http:://rsxbbs.delconet.com/docs/emulex/
but the site doesn't seem to be up at the moment so I can't check :-(

If this is the one I'm thinking you have, it is more like an RL02,
RK05s are front-loading. This is the "take the bottom off the
pack, put it on the spindle, and put the bottom over the top of the
pack" type... no?
No, it is not, this _IS_ the front loading type. But I would believe
tat if Plessey
made several versions, they all might be rather similar as far as the
interface
is concerned.
If so, I belive I have the service docs on it... must wait to get

I think you're right. I distinctly remember (must've been 1982 or so)

"Biddy Biddy? Biddy Biddy?". When was the Buck Rogers series

I have a hazy memory of CESI, but I never heard about replacement PDP-8
CPU boards before. Besides the obvious issue of cost, why were these
made? I can see that with a 1.2uS cycle time, it's like a hex-high KK8E,
leaving you lots of room for peripherals, but is that the only benefit?
Did they integrate any I/O into the CPU module? What's the 40-pin connector
at the top of the board for?
As for scanning issues, I'm not one of those people to harp on bandwidth
since I feed off of a cable modem. I'm personally fond of compressed TIFF
files or PDF for B&W, and depending on if the document is for screen or
printer 75dpi to 300dpi for regular scans.
