IIRC, Atmel had a schematic showing how it (ISP, not a bootloader) could be done- but it was WAY more trouble than it was worth. Best regards, Spehro Pefhany -- "it's the network..."

Its successor, 89S52, has ISP capability (using a few port pins for SPI). The software is free for download, the cable consists of a single buffer IC and a few passives. -- Dipl.-Ing.
