I just bought a SemiDisk ram card with 2MB populated. It came with a test and driver disk with source code !! Anyone ever seen one of these ? It works good.
The manual states there was utilities to expand ValDocs. Anyone come across those ?everything.JPGcard.JPG2M C drive.JPG
 
Oh nice. I knew that semidisk had made a QX-10 variant, but i had never seen one before. I own an IBM-PC and S-100 variant of this card.

One of my QX-10 disks I've collected had a copy of the semidisk driver program and part of the source code, It was missing the actual QX-10 specific driver code though. Hopefully you can get a dump of the disk released online. It would also be nice if you could get some scans of the manual released as well.
 
Here's the extracted files in a zip. My scanner might have failed, didn't sound good so the manual might have to wait.

Discovered I already had a utility SETSEMI.SYS. You can define an M: ramdrive and then it will autoload some of the Valdocs overlay files onto it during Valdocs startup.
I previously thought it was a hard drive utility.

I've got a manual for the 4931 512K S-100 SemiDisk and the 4931 1Mbyte version. It is about 60 pages and printed in 1982. Is that the one you have the code on disk for? I've been looking for that. So far all I've been able to find is a bunch of flux images in raw format that record all 77 tracks of a 8" disk but am not sophisticated enough to convert that information into a form usable to me. Be glad to mail you a copy of the manual for the asm files on a usb memory stick :).

Yes I have the original 8" disk for the S-100 semidisk version, the rawflux images you found are almost certainly mine as i posted my dump to internet archive a while ago. I actually have the manuals (mine says revised September 1983) for them as well, but I can extract the files and post them on IA along side the flux as well fairly easily. I can probably get them up sometime tomorrow.

The manuals i'm more interested in reading are the QX-10 ones as as far as i can tell from the QX-10 source code the are some differences one big one is that accesses to the byte counter register are basically nopped on the QX-10, so i'd like to see if the manuals have any of the details on how the hardware works on that system. @retrogear Any luck since the last time with your scanner?
 
Found the files on archive.org/details/semidisk. Don't know how I missed them the first time around. Thanks! My manual says Revised November 1982. What I have my hands on does not relate to the QX-10. The actual card I have is serial# A00460. Early. The ASM files have 1982 & 1983 copyrights and Michael A. Enkelis wrote them for SemiDisk. I've populated it with 1 meg of memory. It came with piggybacked 64kx1 chips in it. Loads of work for whoever did that!

As to the scanners. Are you talking about the HP large bed mono SCSI scanners that I was looking for? Those I have been unable to find. They aren't in my attic so far as I can tell so I must have given them away :(.

The files i just added sometime after my last post, so they were not actually there before :). I was just about to post a link to the updated archive but it seems you found them.

The scanner question was directed at retrogear, he has the QX-10 variant of the card and the manuals for it, but had been having issues with his scanner when he tried to scan the manuals earlier last year.
 
I haven't got a working scanner yet. I actually forgot about the problem. I'll tinker with it some more.
