Hi,
Working on a 11/44 and need Cards for the power supply. Some
where in its life someone had removed 3 of the boards. I move
the cards from a 11/24 and it works.
I also need the top cover to the cabinet H9545 . Which covers the 11/44
and allows the computer to be tilted up.
Thanks, Jerry

Apparently sometime yesterday the sa/av system that frontends the classiccmp
server was hit by a DDOS attack. The server did an admirable job for a
while, but finally spiraled downward. I am still working on it and trying to
implement a solution.
Someone apparently isn't happy with bitsavers.org, as the DDOS attack is
simply a dictionary generated email address in the bitsavers.org domain.
It's coming from everywhere, so I can't just lock out certain servers.
I'll get it stopped, things will be rocky for a bit, but it will be resolved
soon.

I'm in the process of building a MAX233 Serial Interface for my C64,
and have run into one bit of problem. Which way should the "+" side
of the Cap I have go in the following circuit?

Did anyone else not get Volume 37 Issue 37?
Not sure if I should resend the posts I sent in that were skipped.
Think I missed some other posts, perhaps.
Thanks to Don and Tony for confirming my suspicions.
The system as originally acquired had an RK11-D backplane in addition to
the DD11-P. No cache nor FPP present though.
Looks like I'll be needing some regulators...
Thanks,
John

I had a 4x plextor scsi that was three years old and still cranking 6
CDs a week.
I found that (50 systems in office environment) COOLING is everything.
Those systems that were in coller spots in the building and had better
internal cooling were far less troublesome for failures espeecially
Disks and CDroms(CDRW).

Cooling and the slower ones seems to hold up far better suggesting
vibration may be a factor.

Yes, they are slugs, but I have several and the refuse to die!
I can accept slow over broken anytime. ;)
FYI the older Toshiba 1x and 2x SCSI CDreaders work well on VAX
(CMD SCSI) are faster and seem to resist breaking. They also do
not need trays.
Related topic. CD burner on VAX (under VMS) has any one figured how
to burn CDs?

Hi,
I have around 100 3.5" double sided 720K or DSDD floppies going spare (given
to me by someone else having a clearout). These are suitable for certain
older computers that are not compatible with newer HD disks.
Most of the disks are unbranded, nearly all have pre-printed labels, all
have write protect sliders.
I am willing to send out in batches of 10 untested disks for the cost of
postage (and Paypal charges if you want to pay that way). Postage will be
roughly ?1.50 to the UK, please ask for international postage costs.
I have formatted about 20 disks (on a PC), some disks took a couple of goes
before showing zero bad sectors, a couple of disks I threw away as they kept
showing errors. If you want these formated (tested) disks they are an extra
?1 for 10.
Please e-mail me if you are interested,
Regards,
John
