The pinout looks compatible between a generic DIP28 EEPROM NIC socket and the DIP32 Disk On Chip device, except pins 32 and 31 need to be shifted down two positions, to pins 28 and 27 (on the DIP28 socket).

Anyone tried this? Should be pretty easy to jumper that. It'd give my Tandy 1000RL a combination ethernet/hard disk card in the single ISA slot, and free up another slot in my 1000TL potentially. 16mb is enough for a local disk.
