I have a 7300. I've come to learn a bit about the 3B1, which could be considered the same thing (?). I have a load of disks and docs for the 7300?. Unfortunately they were all stored improperly and are worthless. Being I already have the media (and can prove it) I'd like to have working images of these disks. Anyone have a clue? My hard drive does work, but is a bit flakey maybe :( The thing is a pitn to open up :{ I'd be very interested to hear from humans who are knowledgeable of these units, and more so by those who are currently playing with them. ____________________________________________________________________________________Luggage?

>The 11/94 backplane shown in figure 1-2 in EK-PDP94-MG-001_Sep90.pdf shows a KDJ11-E M8981 in slot 1, an APS module M7914 >in slot 2, and slot 3 empty.

That is to say whats the differnce between the backplane in an 11/84 and that in an 11/94? I can confirm the actual systems were as stated above ie KDJ11-E M8981 in slot 1 APS module M7914 in slot 2 Nothing in slot 3 So how can we tell if the first three slots in each type are compatible?

Figure 8-6 in EK-PDP94-MG-001_Sep90.pdf shows a PDP-11/84-A backplane with the MDM M7677 in the MDM slot, the KDJ11-BF M8190 in slot 1, a MSV11-JB/JC M8637-BA/CA in slot 2, and a MLM load module M7556 in slot 3. Not clear to me if the MLM in this case could be replaced by a second MSV11-J. The 11/94 backplane shown in figure 1-2 in EK-PDP94-MG-001_Sep90.pdf shows a KDJ11-E M8981 in slot 1, an APS module M7914 in slot 2, and slot 3 empty. Does anyone know for certain that this backplane it compatible with MSV11-J modules, and if so in which slots they would go?

The usual distinction is the 3b1 has a "hump" to accomodate a physically larger disk drive. There has been a suggestion, though debated, that the 3b1 also has a beefier PS. > I have a load of disks and docs for the 7300?. > Unfortunately they were all stored improperly and are > worthless.

Because they contained UNIX SYS V R2, most everyone was pretty careful about throwing around copies. So I don't know of any online images of them. Your best bet might be to find someone who has a set they'll send you, or perhaps a set they've backed up. In general, the first place to look is Peter da Silva's page: http://unixpc/taronga.com > My hard drive does work, but is a bit flakey maybe :( There's a classic issue of corrosion on the PS connector.

I used to do quite a lot with them, but haven't fired one up in probably 5 years. I used to maintain the archive that Peter maintains now. BLS
