    Smile Hi Y'all from Chattanooga, TN

    Hi there,

    Just joined this forum and I hope I can provide some help - and also get some for my own projects - because everyone can use a helping hand, right?

    About me ... well, I guess, I'm almost an oldtimer. Started "programming" on a Texas Instruments TI-57 when I was 14. A year later I was allowed to use a friend's Commodore PET-2001 which introduced me to BASIC and Assembler. At age 17 I washed a lot of cars to be able to place one of the first orders for a Sharp PC-1211 with a CE-121 cassette interface. Took another year and more car washing to also get the CE-122 printer.
    Had an Atari 800XL during my early days of college. Had operating jobs helping with day-to-day business of running IBM /370 and 3031 main frames.

    These days I'm doing electronics design and software engineering. Arduino and Raspberry projects are one of my hobbies - well, I've built embedded systems for decades using whatever was available (6502, Z80, 8080, 8086, 68000,...)

    Most of the electronics and computer systems I owned are still in my posession, I would not call it a "collection", but it's my personal history with computers:

    • the 1977 TI-57 programmable calculator
    • the Sharp PC-1211 with CE-121 and CE-122 (and a replacement PC-1212 because the 1211's LCD died)
    • an Epson HX-20 with internal RF-20 RAM extension which was used as a navigation system (ex property of the German Luftwaffe)
    • a shelf full of "PC" stuff ranging from the 90's up to today


    Looking forward to having some great conversations,

    Markus.

    Welcome Markus,

    I'm in Chattanooga as well. I started on a TRS-80 Model I and I mostly have TRS-80/Tandy Systems. I do have other systems and interests, just trying to limit it some these days.

    I used to do a lot of 6502 programming. Not so much anymore. Still have a couple of 6502 systems, though: a SYM-1 and an OSI C2-OEM.

    Hi Malcom,

    Hey that's cool that we are located in the same city. I remember the TRS-80 systems, although in my "younger" years I was a "6502" guy. Had to do a lot of Z80 programming though because of various jobs I had during my college time.

    Take care,
    Markus

    I remember the SYM-1 ... I had a KIM-1 before I "upgraded" to the Atari 800XL. The KIM-1 ( https://en.wikipedia.org/wiki/KIM-1 ) was kinda similar to the SYM-1.

    It's nice to be able to chat with people who actually know what I'm talking about when it comes to the early days of "personal computing".

    Markus.

    The SYM-1 was a knockoff of the KIM-1, but it had more sockets and connectors for IO. I wrote an EPROM programmer program for it. At work, I wrote a memory bitmap program for it. All in 6502 assembly code. On the OSI, I wrote an OS overlay for a daisy wheel printer driver.

    Wecome from Australia. I am sure you have a lot of knowledge there and some interesting hardware

    I'm in Redbank myself.

    I've been slowing down on the collecting front lately, but I've got most of the Commodore 8 bits,
    some 8 bit Apples, Trs-80's, IBM 5150, some Tandy 1000's, and a random atari and ti computer.

    So if you start needing boot disks or the like, feel free to message me.

    Later,
    dabone
