      Fantastically enough, I have an AST networking sidecar (PC NETIIjr) as well as the ISA card (PC NETII).  I have not used them, but the sidecar was a very, very lucky find.  I just happened to have picked up the cluster attachemtn sidecar from EPay and received it yesterday.  It was my first one, but I know others with them.  If I come across another cluster attachment...I would be more tha nhappy to send one your way for cost of shipping.

      Bill,

      Next time I'm down there in Jersey I need to come over to your house and poke
      around. If you see a jr sidecar with a row of DIP switches and a coax
      connector, please let me know!

      What would be a real find would be an ethernet adapter for the jr, but in all
      my research, I have not seen any reference to such a device from IBM or any
      third party (like 3Com).

            I used to have a PC Jr, but I gave it away x years ago.  I picked up these items from the local thrift shop to either give away or when I came upon a system. 

            Let me know if you'd like to help test the inventory program by contacting me directly.

                Ok...a quick reply to my own question of pain....but
                I checked EVERYTHING....over and over, but everything seemed to be hooked up the way I remembered. Then in an effort to calm my wife down over a pesky-loud power supply that would constantly "buzz" while plugged in, I finally changed it out. (This power supply was hooked into the main CPU, mind you, and worked to boot the jr up just minutes before)...
                After changing the power supply out, it was magic...the HDD unit worked... It seems that there might not have been enough juice getting to the main power board, which allowed it to boot ok, but caused power issues...or lack-thereof to other hardware...
                I'd never have thought it to be so simple of a fix...
                 
                Still....if someone has a users manual for Racore 1511/1521, a scan would be greatly appreciated...
                 
                Also...In lines with VCF (My questions never cease...do they?)...I had an email conversation with a gentlemen about a year ago who said they sold a legacy floppy controller for the pcjr at a VCF which let the jr run a 1.44mb floppy drive....anyone heard or seen this before???   Must be a VERY rare option if it existed...

                  Subject: Re: [midatlanticretro] Any PCjr's left out there?

                  Ok...a quick reply to my own question of pain....but
                  I checked EVERYTHING....over and over, but everything seemed to be hooked up the way I remembered. Then in an effort to calm my wife down over a pesky-loud power supply that would constantly "buzz" while plugged in, I finally changed it out. (This power supply was hooked into the main CPU, mind you, and worked to boot the jr up just minutes before)...
                  After changing the power supply out, it was magic...the HDD unit worked... It seems that there might not have been enough juice getting to the main power board, which allowed it to boot ok, but caused power issues...or lack-thereof to other hardware...
                  I'd never have thought it to be so simple of a fix...
                   
                  Still....if someone has a users manual for Racore 1511/1521, a scan would be greatly appreciated...
                   
                  Also...In lines with VCF (My questions never cease...do they?)...I had an email conversation with a gentlemen about a year ago who said they sold a legacy floppy controller for the pcjr at a VCF which let the jr run a 1.44mb floppy drive....anyone heard or seen this before???   Must be a VERY rare option if it existed...

                  Next time I'm down there in Jersey I need to come over to your house and poke
                  around. If you see a jr sidecar with a row of DIP switches and a coax
                  connector, please let me know!

                  What would be a real find would be an ethernet adapter for the jr, but in all
                  my research, I have not seen any reference to such a device from IBM or any
                  third party (like 3Com).

                    BTW, thanks for joining MARCH! Welcome aboard.

                    You may have found that PCjrs were made with two different power supplies. I
                    believe the early jr's had a 45W supply while later units had a 65W supply. I
                    may not have the exact values correct, but you get the idea. The jr's power
                    supply is split between the power brick and the regulator card that sits
                    vertically inside the chassis. The larger power supply used a bigger power
                    brick to supply more juice to the more robust regulator circuity on the card.
                    These two parts should be matched.

                    Even the larger power supply could be overtaxed by adding extra side cars so
                    IBM sold a power expansion side car that also had a power brick. Does the
                    Racore HD expansion have a power supply with its own power brick? An early jr
                    barely had enough power for the floppy drive so adding a hard drive would
                    certainly demand additional power.

                    Jim Strange enough, the Racore has its own power source as well. Its a different one of sorts, as the power input connector to the chassis is a DB9 connector

                      Strange enough, the Racore has its own power source as well.  Its a different one of sorts, as the power input connector to the chassis is a DB9 connector instead of the standard IBM Power supply connector.  So to accomplish this power hookup, I have a power sidecar with a power cable and 4 pin male connector wired, which then leads to a homebrew 4pin female to DB9 cable.  Works good.
                       
                      Now that I was successful in getting my HDD setup to work again, I wanted to to do a three tier system of purely Racore chassis drive systems.  I put the HDD controller board on the second tier with the 3.5" drive in the drive slot and the HDD in the third tier and the HDD cables coming up from the controller board and hooked in....and the verdit is????    NOGO....
                       
                      There seems to be something with the custom floppy controller card and the 10 pin signal cable that the HDD system doesnt like.  I dont have a list of the jumper settings for the controller board (why a users manual would be premiere...), so I think the only thing I really could do is to pull out one of my modded floppy controllers for a two-drive system out of the shed and make a new floppy cable to be able to reach to a third tier.. (whew!  Alot of work for a simple drive addition!!)  But always a fun learning experience...
