I have a recently recapped SE/30, and I have installed a SCSI2SD (v5.0a) inside it. I don't have a (working) CD drive, and the floppy drive is broken, so I configured SCSI device 3 to be a CD-ROM drive, and put the System 7.5.3 installer inside it, along with a copy of the patched "HD SC Setup" utility, so I can format the other SCSI devices, which are configured as 2GB hard disks.
Booting from the "CD" works fine. Formatting the disks works fine.
I cannot get the System 7.5.3 installer to complete. After copying a few files, it complains that an error occurred, and then aborts.
Additionally, if I attempt to copy the contents of the "CD" to a hard disk, after copying a few files, I get an error that says a "disk error" occurred. It's not the same file every time, it copies a random number of files successfully before erroring.
I've have also had a few random bomb errors, although these do not happen reliably and I haven't managed to come up with a way of causing them on demand. They may have stopped after I swapped the RAM, although that is speculation.
Things that I have tried:
* Playing with the "SCSI Host", "SCSI Selection Delay", "Enable Parity", "Respond to short SCSI selection pulses" settings on the SCSI2SD. No combination seems to make any noticeable difference.
* Swapping out the RAM on the SE/30. I initially thought the RAM was bad, but I replaced it with a different set and the symptoms are exactly the same.
* Removing the case back, in case something was overheating inside.
* Replacing the microSD card with a different one.
None of these have altered the symptoms at all, and I'm running out of ideas. Any suggestions would be very welcome.

Hello,
I have many rl02 disk packs for my pdp 11/34 and 11/05. I have just been
stacking them upright, but that has not been the safest or the most space
efficient. Were any kinds of shelves made for these disk packs, perhaps
similar to 9 track hanging tape racks? Trying to make things look more
organized too.
Hoping someone here has one and can share a pic, perhaps it is a design i
can duplicate and make with some woodworking tools.
Thanks,
Devin D.
If all goes well I will be driving up to WCFMW on Friday, Sep 9th, with a
van loaded with DEC and PC items.
If you are interested in any DEC gear, please contact me as early as
possible so I can get it loaded.
If you want to stop here on your way to or from VCFMW, please contact me
ASAP to set up a day and time. I am located about 12 miles west of
Champaign, IL ( I-57, I-74), which is about 2 1/2 or 3 hours south of WCFMW.
If anyone is interested in DEC chips, I will be taking offers on several
DEC boards (M7819, DZ11 and M8044, MSV11-DD come to mind- I have dozens of
each) with the gold fingers cut off. I hate to do this, and you might hate
it too, but I have a lot of stuff sitting here for years that need to go. I
also have an assortment of several thousand unused ECL chips.
Please contact me off list if you have any interest or questions. If you
wish to talk, I will gladly give you my phone # off list.
Thanks, Paul
I picked up a VT220 passing by some clean out a while ago.
Green phosphor, powers up and passes self test.
The keyboard has 3 broken function row keys, keycaps.
Free to pickup in North Andover.
Shipping would be heavy and awkward with the CRT.

Hey all,
I’m looking for an Itanium Merced machine, such as an HP rx4610, HP i2000, SGI 750, etc.
Please reach out if you have a machine you’d like to get rid of or have any leads!
Thanks,
Larkin
I have many 8mm tapes. A few are new. First comers get new ones.
I have a few 8mm cleaning cassettes
I have about a dozen DLT-II tapes.
I have some Ultrium LTO fibre-channel SCSI drives that were removed
from a tape-mounting robot several years ago. I never used them in my
computers. The mounting bracket for one was modified to have an
internal power supply -- which might be inadequate. I have two
Fujifilm 200/400 GB Ultrium 2 LTO tapes.
I have a 5.25" floppy drive.
Any of these are yours for the price of shipping; local pickup is OK
too.

Some quick questions on fixing up a TU58:
1) Can I plug it straight into a pdp11/23+ CPU with a 10 pin ribbon cable?
2) Can I hook the 10 pin ribbon cable on it into a normal 11/23 or 11/73
bulkhead to get RS232 for hooking up to a PDT11?
3) Can the PDT11 handle anything faster than 2400 baud on the extension
ports? Can it do faster speeds in one direction?
4) Is there any possible use for this thing :-)

I know this is a long shot, but I just acquired an SSM SB1 S-100
board with no chips. Everything on the board is easy to source
but the SSM2000 chip. Does anyone have one for sale or know
where to get one?
Thanks,
Bill S.

Next week I will be in the Huntsville, Al, USA area for an entire day with no commitments. Does anyone have recommendations on how to spend my day? I have been to the space and rocket museum several times. Any computer museums or displays, especially of space-related equipment? Any good surplus stores? All suggestions welcome.
Thanks,
Will
