Once I tried my first Metcal MX-500 series iron, I never went back. With proper
tip selection and technique, the same pencil iron will work for anything from
0201 components to PL-259 connectors. And it heats up and stabilizes in under
30 seconds from a cold start after a tip swap. I've spent a

Cool! Thanks for the warning about it. Fortunately the Power-One

Well, I had to look it up. The LAS723 comes with a 2.5V reference
and not a 7V.

Anyone has the Inverse Assembly and Logic Analyzer setup files that should
go with the HP 10343B SCSI bus pre-processor? Another one that I wasn't able

One of my first jobs at DEC was on terminal sales.
The LA36 printing terminal had the logic and PSU cards mounted in the
plinth.
The logic card was on the back of the pull down door and the PSU inside.
So easy to service it wasn't true. This compartment was quite roomy

Oh! And if you're using the "boot cdrom" mnemonic, make sure that your
CD-ROM is actually set to SCSI ID 6, otherwise you need to substitute in
your boot path i.e.

Definitely check that!

Are SCSI ID numbers likely to be an issue?
Which ones are most commonly used on SparcClassic?
I collect Sun lunchbox systems like the Classic.
When I get the SCSI bus is hung message, I add or remove the SCSI
terminator, depending on whether one is present and, in my experience,
the problem usually goes away.

With a lot of help from Dave Gesswein and Warren Stearns we were able to
get the MARK12 PDP-12 tape formatting program off a LINCtape and int paper
tape format. Running it showed that a diode on the field-0 core stack had
failed during the week making memory in the range of 4000-5000 unusable.

Hello Adrian,
how are you?
Maybe you still have the SDI disks aside for me?
Any time to ship them to me?
Thanks in advance!
