  1. AST Six Pack Plus - is there a way to put the ram at 640K ?

    Disabling the memory on a Six Pack Plus can be done by setting the jumper to indicate zero memory installed. Removing chips is not necessary. Though if doing that, swap the card with a RAM less I/O plus clock card and send the card on to someone with a RAM limited system.

  4. Courier Woes - why I'm holding off on my rebuild/flip idea

    USPS up until now has been very reliable, so I'm a bit ticked off....

    Ordered M/75 on the 8th, was "Out for Delivery" on the 15th, then turned up at a 6:41pm as "Ready for Pickup" at our Post Office. No slip, no note in the tracking - nothing. Weird since our regular carrier comes by as late as 9:10pm to deliver mail and parcels.
