Craigslist Find

Well it's been a while since I found one that was worthwhile (I think). Finally someone that wasn't asking a million dollars for system and it looked from the pictures it had some interesting cards in it. It was posted on December 2nd and I emailed him this week and he still had it. So I met him and offered him $200.00. I think I did alright on it.

Here's what it was.

A late model Apple II plus (Serial number is in the (500,000 range)
An Apple III monitor
2 Kraft KC3 Joysticks
A system saver
2 Disk II drives

and the following cards...
The usual Disk II controller, Parallel Card and Apple Language Card that you would expect.
A videx VideoTerm with inverse ROM.
A Hayes MicroModem II with Microcoupler and all cables
A Stellation Two Mill Co-Prosessor card with a Micronetics ROM.

The unit works and boots. I am going to clean it up a bit, glue the rubber feet back on, and download the Stellation software and give it a try.

See the pics below....

THanks,
Jay

And a Videx Soft Switch Card...

My Apple ][+ I got a decade ago, came with the Videx Card, and a missing IC, the 9336 ( or 74LS124, IIRC ) where the Videx Soft Switch board is plugged in...

Re: Craigslist Find

Any idea what the Micronetics ROM does? Maybe some sort of 6809 monitor?

Re: Craigslist Find

Not sure what the ROM does. I did a little research and it looks like it is an assembler and monitor for the 6809.

Also I didn't realize how invasive the Videx card was. The II plus was a little before my time so when the IIe came along it already had most of the functionality in the videx card.

I will upload some more pictures. There was a lower case ROM in the IIplus, the keyboard encoder looked different since it was made by Videx and had a 9 pin connector on it and replaced the apple encoder and no switch for the reset button finctionality. I am going to have to do research on this card, but it looks like I have all the pieces to it.

Also didn't realize that the motherboard had to have jumpers put on it too.

My most Interesting find to date. Any pointers or help where to find the Videx documentation would be appreciated[inline:attached_image_#].

Thanks,
Jay

No, I missed this project.. Cool...

I will need to see if my Videx Card works, and then build the SoftSwitch...

Also, I don't know if I mentioned it, but I have all the Components to build some of these boards:
Apple II 68008 Co Processorcard project

I wasn't sure if the 68008 Processors I got were "legitimate" or not, so I bought a couple more for Reference:

Re: Craigslist Find

Hello Mark,

if you really intend to make such boards i´d take one empty PCB...
like you might recognize by the pictures of my board... it was made
in 1984 and in that days i didn´t have that much experience like
today in etching double sided PCB´s....

by the way.... i´m at the moment performing a kind of "face lifting"
to the entire site ..... by that i´m also performing a check of all present pages....
after examining the entire content i recognized that the currrent content...

all together sums up to more than 300 pages ( counting only the "main entry pages"
and thereby meaning that most so called "entry pages" which are listed in the
indexpage contain by printing in normal pages would result to total amount of more
than 2000 pages..... or in other words most so called "entry pages" result each to
average 4 to 8 pages of printed content )........ so the facelifting might request
time up till end of January or mid of February.....

at the other hand i also recognized that some several dozends of pages haven´t even
been displayed with linking titel at the indexpage...... so after the facelifting
it´s recommended to review the site....

In this spring i also intend to examine the entire contents of my Apple II disk archives....
this will also turn out to become a time eating task due to the fact that just the
5,25 disks amount up to more than 3000 disks and the 3,5 disks will count up to 1500 disks....
specially i´m focused to sort out all hardware related disks, that contain software
related to any kind of interfacecards......

there should also be some disks related to the 68008 card.....
that card is able to handle 68k CPM .....

I did find a discrepancy on the BOM, there is a component listed on the PCB that is not in the BOM.. A resistor, IIRC..

I am looking forward to trying 68K CP/M, and I would think that the 6809 FLEX and OS/9 could be adapted to the 68008 as well...

Hello Jay,

in my opinion the EPROM contains the MUMPS programming language implemented by Micronetics Design Corp.

I found an "information sheet" of MSM-09 MUMPS language in the March 1983 MICRO magazine n.58 issue that lists it (check the last line of the page) with a tag price of 695$ !

The MSM-Apple (Micronetics Standard Mumps for Apple II) is nominated in the MSM Utility Manual:

I believe that You stumbled upon an Apple II used (maybe) in a Medical/Hospital environment; did it came with any software in the form of floppies?
I think that Your eprom is as rare as an unicorn and, as such, it should be preserved!
You must take a dump of that eprom a keep it apart.

I've been able to buy a Mill board off ebay last month that is a Rev.c like Yours, I still have to check if it works.
I noticed that our cards have two more chips (far left on the board) that other revisions lack, does any one know why?

Here is a picture of mine:

Cheers
