Axlon RAMDISK 320

This is the Axlon RAMDISK 320, a Disk II-sized box that can connect to the Apple II (and reportedly also to the Apple III, with a different interface card) and serve as a fast RAM disk. It looks nice. Because I assembled this in pieces, I have not actually had a chance to test it out yet, but I think I am almost at a point where I can. I got the main unit itself a couple of years ago, and recently found the missing interface card. Earlier, someone else on eBay had sold a complete unit with a bunch of the disks, and was kind enough to make copies and send them to me. So, rather than wait until I finally get around to testing this all out, here is what I have so far.

Here is one of the ads.

And a brief review from Softalk December 1982.

And here is what the actual unit looks like. It is in a box essentially identical to a Disk II drive. Inside there are RAM chips and a battery, the board says designed by MOS Sorcery. Mine got kind of knocked around in shipping, and the fuse in the back basically shattered. I also have the card for the Apple II. There was a version of this for the Apple III as well, but it must have used a different card, since this card is too long to fit in the slot of an Apple III.


The disks that I got with the drive were v1.1 of the DOS System Master, and v1.0 of the Pascal system master.

From a helpful eBay seller, I was able to obtain copies of a bunch more disks. This is the photo of the disks he sent me, along with copies he made of them. There are two copies of v2.0 of the DOS system master, two more copies of the Pascal v1.0 system master, a copy of v1.0 of the DOS system master, some CP/M support files, two demo disks, and a disk that says it has the source code on it. Sadly, that source code disk had read errors. I will attempt some surgery on it to see what I can retrieve but it might be effectively lost. I have not tested these really at all. The DOS disk boots.

All of these disk images can be grabbed here:

Microsoft Z-80 SoftCard manual (draft)

I recently got a (signed!) set of manuals for the “Microsoft Z-80 SoftCard” that were originally provided to the designer of the SoftCard, Don Burtis, for the purpose of proofing the text. They are interesting in that they contain some penciled corrections, and also that the product itself was called the “Z-80 SoftCard.”

Sometime after this, but before the product hit the market, Zilog asked Microsoft to remove the “Z-80” from the name, and the card was actually sold just as the Microsoft SoftCard. For comparison, here are those manuals:

I scanned the manual as it was, for the historical interest, and if you’re curious about what corrections were penciled in, I’ve noted all those that I saw in the table of contents of the PDF. Mostly they are correcting technical typos.

Apple III ProFile Sales Kit

This is the Apple III ProFile Sales Kit, for dealers, to encourage customers to buy a ProFile.


I have scanned the contents of the binder here:

Apple III ProFile Sales Kit (PDF)

It came with a bunch of Backup III disks (the program and then a 6-disk set, designed to be restored onto your ProFile). It restores a bunch of programs and a rolling demo. Here are a couple of screen shots of the rolling demo. I was successful in restoring it within the emulator and making it go.

Here are the disk images themselves: Apple III ProFile Sales Kit disks.

I did not include an image of the Apple III Business Graphics disk, and the expected VisiCalc III and Quark Catalyst disks were not there. These would all have been protected anyway. If you want the PDF scans of these disks, then: Apple III ProFile Sales Kit disk scans (PDF).

I haven’t done much real exploration with this yet, but I’m posting it here so that it’s posted, maybe you’ll be able to do the exploring before I do!


A few Apple III images from Ian

I have long been meaning to post these somewhere, but I will post them here for now. These are a few Apple /// disks that an online friend of mine, Ian, imaged from disks that he had around that were labeled as being for the Apple ///. I have not gone through them very thoroughly, but I have gone through them cursorily now, and I’ll put them here with any notes I have on them. If you figure out more about them, great, let me know, I’ll update this post. But just so they are somewhere.

The whole set of disk images/photos are here: ian-apple3

Here’s what’s in it:

The Apple /// Professional Solution Demo. Three disks. You boot disk 1, are asked to insert disk 2, and then you can watch a “rolling demo.” It seems though that either there were some errors in the imaging, in the emulation, or in the program itself, since for me at least it didn’t go into rolling mode properly, and I managed to get it to crash out by trying to move to a different part of the demo while it was running. The third disk (“follow-up”) is kind of interesting in that it contains a bunch of templates for the dealers to use (in Apple Writer, I believe) to follow up with potential customers who saw the demo. The text versions of these are in the “janetta” folder in the archive.

Apple II emulation disk. The disk is a copy and is labeled “64K ?” which is intriguing, since normally Apple II emulation is restricted to emulating a 48K Apple II. I’m not sure what was intended here. However, the disk when it boots looks pretty normal, except that it crashes on the couple of DOS 3.3 disks I attempted to boot with it. So.

Microsci A74/A143 driver disks. Version 1.2 and version 1.4. And something labeled “UTL”. These contain drivers.

Apple software revisions disks. Apple Access III revision, and SOS revisions A00 and A01.

Microsci Gameport III modification diskette v1.1 Apr 19 1983. Modifies the Emulation disk, presumably to allow for some kind of game input devices on Apple II games.


TG Products modifier. Boots on an Apple II, modifies the Apple II emulation disk, presumably to allow some TG products game input device to work with Apple II games.

Business Apple Group, Inc. Business BASIC .003. Disk of what appear to be example programs in Business BASIC. I didn’t try these out.

PKASO driver files for the Apple ///, Nov 9, 1983.

On Three Lazarus /// v2.0. Only side 1 was imaged here, but side 2 is available from

PFS, PFS: file, PFS: report, PFS: report sortwork. These don’t boot and are probably protected.

Quark Word Juggler data, install. Neither boots, and they’re quite probably protected.

I think that’s all of them. So, now they are on the web and Google will eventually know of them.
