 The Franklin Computer Company made a clone (ACE 100) of the Apple ll computer. The printed circuit board is a similar layout and the operating program in ROM was an exact copy. These Franklin computers are an interesting curiosity for computer collectors. This computer is in excellent condition. The computer has 4 interface cards installed. 1.ADA lab SN 4092908 -looks like data acquisition with ADC & DAC. 2. Dumpling -64 Microtek PN 926041.1(1983) 3. Disk interface card for 2 floppy drives 30-0043. 4. Franklin sn10974 39035 RevA ( don't know what this card is) . 5.

Bob Luther's Book "the first Apple" Just off the press - here is where you can buy your copy Amazon  Soft Cover book-  here is ebook link   This is book is about the Apple 1 computer. I found the interviews Bob did  with current owners and the history makers still living that made & marketed the Apple 1 computer really great reading. Bob is the owner of the very first Apple 1 computer sold directly to consumer.

 PDP8S minicomputer  -    Information      more info       Wikipedia listing       
The S in the model name was put their because the CPU operated serially on the instructions and not parallel - this made the computer less costly but very very slow.  Some folks think the S was for slow or small - true but not why Digital Equipment Corporation put it in the name. Looks like only 3 or 4 in museums or private collections.

  1. Hi David: Great to talk to you again today! Very pleased to be the new steward of your DEC PDP-11/10, it will be put back to good use as soon as possible, will be having fun getting back to our programming roots here! Really enjoy reading about microcomputers (Scelbi &c) I've never heard of on this blog! regards and all the best from Endicott NY, the First Home of IBM, Roger Anderson

    1. Hi Roger - I am looking into how to ship the computer to you - sure glad to hear you like the content - I have fun writing the content. I learn a lot also in researching information for each post. Just found that the MMD1 microcomputer is referenced as the very first single board computer. My Colleague John Titus designed this and I helped him with ideas for the design. John first computer was the MARK8.

      I have one of the MMD1 prototypes in my collection from the old days when John and I worked together.

      I will be doing a blog about the first single board computer.

  2. Hello David!
    Very happy to be the new caretaker of the PDP-11/10 minicomputer, many thanks for making it all possible!

    Our hope is to get it back to life and incorporated as part of a retirement project: BioPhysics research focusing on the local application of a new modeling program: the Jefferson Project by Dr John Kelly of IBM, with RPI (Rensselaer Polytechnic), for tracking pollution and invasive species, in our case in Lake Champlain, site of our summer/retirement home. Incredibly exciting and fun to see if this machine can make a contribution!

  3. Hi David!
    Very pleased to be the new caretaker and user of the PDP-11/10! Many thanks for making it possible.

    Our retirement project is BioPhysics research using a program developed by Dr. John Kelly of IBM with Rensselaer Polytechnic here in NY to track pollution and invasive species in bodies of water, in our case Lake Champlain, site of our summer/retirement home, and one of the most beautiful bodies of water in the world. We hope that the PDP-11 will play a small part in this work... a great use we think! all best, Roger Anderson Endicott NY

  4. Do any of the Franklin Aces have a DIP Switch block added to the motherboard? The model (a 1000) we had documented the quirky feature, and I did actually solder in the switches onto the board. Most interesting feature was that you could load a patched copy of the ROMs into memory (or a copy of the Apple Integer Basic ROM) and then have that "locked in" until the power cycled. That was a particularly useful tool for boot tracing protected disks.

    1. Hi William - I am slow to respond because it took me a little time over the holidays to look inside the Franklin Aces for the DIP switches. I did not see and DIP's in the ones I have. I never used an Ace so have no real experience with them. They did sell them in the 10's of thousands from what I have read.

      Did you get a lot of use out of the ones you used? I don't hear much from people who actually used one. I do have a good representation of Franklin computers in my collection. Some are duplicates - that is why I put these up for sale here on my blog. Anyone interested I don't expect to get much for them. Thank You , David.
