    The 1001 was the first one, not the most common. The rarest is the 26-1008.

    I have the 26-1008 which is not listed on either of these sites.

    I am kind of a closet Model 1 aficionado, I made a pretty nice exhibit for VCF East 4 about 12 years ago.

    and another at the University of Delaware:

    I still use my stringy floppy drive, I restored the drive belt, the hardest part to getting them running after so many years. If anyone is interested I can fire up the 1008, it was never supposed to have been sold, that old story. Like the Commodore P500 a few got out. I think at this point the RF police was let this one live.

    Do you have pictures of the board in the 26-1008?

    As I understand it, the 26-1008 was the TRS 80 1 that the FCC pulled from stores due to RF interference problems, as they were no longer legally allowed to sell the Model 1 as it was, due to new regulations. Radio Shack put out the Model III as a result. A few 26-1008's got out as demo units or a pre-mass-production run, but they were never officially distributed as I understand it. Probably execs and a few store owners got them, like the Commodore P500. 26-1008 was never in the Radio Shack catalog, to my knowledge.

    So, if you have one, consider it very rare. Aside from mine, which is serial number 38, there is someone here on this board who has/had one.

    In my opinion the 26-1006D is the most common. 26-1007 was controller card I think.

    This unit has never been opened, so I have not checked the motherboard. I read somewhere that a 26-1008 had MOS chips. Unless there is a compelling reason I believe its best to preserve the seal, so I don't void the warranty.

    What model number did the Japanese-produced Model 1s have?

    Interesting that it doesn't have the updated ROMs. Can you get a picture of the bottom to see if the ROM daughterboard cable can be seen?

    There is no ROM daughterboard (or any visible flat cable) in the 26-1008. I have a 26-1006 that does have a visible cable for comparison. How can you tell that the ROM is not updated? Just from the printmem command? Would not the latest ROMs be installed just because it's the newer model? Maybe no add-on board would be needed. Please educate me on the subject..

    Well, bugger me... that just looks like your regular run-of-the-mill G-board Model 1.

    Is the small pcb the XRX mod? What makes it different than any other rev?

    Is the "SHACK" normal for a standard G-board?

    Mine has something different (but illegible) scribbled on that resistor.
