    So this is a link to a fairly common Miner 2049er. I remember back in about '84 being at a Chicago Fair and one of the guys buying on of these and cracking it open, it had a big square chip with a blob of black glue-ish. But what was interesting, was that, for me, it was my first introduction to surface mount technology. 

     

    Does anyone here know when the first surface mount chip was ever used in a device made for the TI? I think the tour-de-force on the front was the IDE controller.

    As most know, John Dow wrote the Dow Assembly Primer, as well as a xb flight simulator.

    In the Assembly Primer - he mentions the Dow Editor/Assembler package.

      Has anyone used that? Know of it?

     

    Also, there was work done by Mr. Dow, mentioned in Micropendium, about an assembly language version of his flight simulator, but I don't think that ever made it out the door. (Glad we have the excellent Spad Flight Simulator and the related columns from Micropendium).

    Does anyone have a preferred vendor of TMS9901's?

    I'd like to put back a few for a rainy day, but it seems it's gotten increasing easy to purchase bad chips, or chips, with new silk screens - that aren't even the chip you ordered (counterfeit).

    >I personally never liked saving backups to floppies as one bad floppy screwed everything up so I copied from one drive to a second drive.   Myself, I do not have that requirement so it is not a pressing issue for me as I have a DREM.

     

    Wow, that brings back some memories. I did that thing with like 15 floppies, and had it fail. A bit like loading OS/2 from 25 floppies. So in short, you probably have become the DREM, sales person of the month! -=)

    Let me follow up, i think a good route for my playing would be to purchase some protoboard and plug it in to the side of the 32k board.

    Arcadeshopper do you know what part, I'd need to get that would allow me to plug in to the 44 pin connector on the side?

    Thanks!

    Right so I take my existing TIPI + 32K, pull the 32k and replace with AMS goodness.

    Then I have a 32K sidecar unit. Which is Ok.. I was wanting to try some things like Mack McCormicks Slow Down Circuit that used to go in a speech syntezier case, but the 32k unit might be easier, because all the bus pins are more easily exposed....
