    new arrivals, ive put them on ebay.

    For the MK4200 I have a few different kinds:

    Cerdip MOSTEK
    Cerdip NCR

    only a few of these

    Plastic MOSTEK
    Plastic NCR OEM

    These are 4kbit static RAM ICs.

    TMS1100 is worthless since its mask programmed only interesting for collectors.

    Since the chinese copy off items, there are only a few variations online for some part kits,
    Im increasingly listings items they will find more difficult to source if any.

    About profits, I can just so cover running costs such as warehouse rent.

    Fleamarket yes since the market for old ICs is volatile, and often restocking is not possible.

    Im importing Intel 8080 and 8086 for some time but its unknown how long supplies may last.
    Soviet variants Ive listed dont sell much if any.

    There are other BBS where it is quite normal to sell small amounts of old CPUs, but im not specialized just on old CPUs.
