I just recently ran into a set of DecTape II carts with bad bands that haven't been archived yet. Mind if I ask for a few from you? 15 is how many I'll need, if you don't mind.

Sorry to necro, but I have the same drive, actually. That is decidedly not standard IDE -- they have power over the connector and no other means of powering it. IDE does not specify +5V or +12V over the ribbon cable anywhere except extended 44-pin connectors.

Done! Thank you very much! ^,^

Haha -- okay. Lemme try -- I was a bit new as well.

Also of note, that board is totally useless without the adjoining PSU/control board: I'm attempting to get these things as documented as I can, since the H27 has nearly no docs at all, so additional "specimens" are in my wheelhouse.

I worked with @Alegend on this one, and while $1k was a bit expensive, it was worth it. I now have one in my BA23 chassis and it works like a dream. Well done, and thank you!

If you're willing to part with it, I have another H27 here that has a totally destroyed controller board that I would like to fix up. Please PM me, if you're interested.

Yes, it simulates both an RX01, as well as Heathkit's extended variant of the drives. In extended mode, you can use those drives to format RX01 compatible disks at the ODT prompt.

That's a floppy controller board for a heathkit H27 dual floppy drive. Works with an H19 terminal and an H11 PDP-11 / LSI-11 minicomputer kit computer from Heathkit. Looks like this: The board goes in the *bottom* of the H27. If you have the tooling, ROM images from those ROMs would be ideal...

Maybe contact Bitsavers? Al doesn't have any of these manuals up there, and probably should. :P

FWIW, there are more than just the one EPROM for the Z80 on the controller board -- there's two other ROMs as well, according to the WH27 schematics.

Hoping to get an image of these during VCFSW from my working H27 if I can. With any luck, I'll see about handing it off to Bitsavers to archive once I've got it.

If anybody still has physical manuals, it would be good to try to get these things imaged properly. The service manual I linked has the entire BOM, schematic, and board layout for this machine, so it should be possible (modulo any GALs or ROMs, of course) to make a new machine from it. The copy...

Okay, so, I found (what seems to be) the only copy of the owner's manual and the service manual on the 'net. I hate to link it, since it seems like a scummy site, but it's at https://www.manuals-in-pdf.com/download-SMC70-SONY-p-473259.html and...

Incidentally, there are more disks up on archive.org here: https://archive.org/details/smc70-disks

Yeah, I found those after scrounging around for a while, fortunately. :D

Specifically looking for a service manual, if possible, and the pinout for the RGB multi out (like the original folks that started this thread were after). I have the right Trinitron at this point, just need to make a cable for it. I suspect mine might have some trouble, though, given past...

Apologies for necroing this thread, but did you ever manage to find any manuals or software for this machine in your collection? Asking as I, too, have an SMC-70, and would like to get it working as well. :D

Fortunately, I do. I have two Prusa Minis and a Prusa i3 MK3s MMU2S in tip-top condition. :D

Bah. My account is apparently still too new to do PMs. I'm definitely interested in one of these, since I purchased mostly gutted BA23 case without the fans or the PSU. Is there another way of contacting you, perchance, other than the vcfed forums?
