I received the following letter and was not much help. If anyone can comment please do so!: ---------- In the E.Arthur Brown catalog, there is advertised two cartridge port adaptors. One converts the cartridge port to a "standard 44 pin .156 spaced edge connector" that "fits directly with the Radio Shack proto- typing boards". The other is a 24 Bit I/O board with 24 bits of individually selectable input and output or 16 bits of I/O and 5 levles of prioritized interrupt inputs and the ability to WRITE to the port (according to the ad). My question is this: could either of these be used to provide expansion capability to the ST, for example, to hook in a VGA board and monitor or a math co-processor board or Ethernet card???? Big dreams have to start somewhere, don't they... --------------- Larry Rymal in East Texas <Z4648252@SFAUSTIN.BITNET>

Both boards were developed here in Colorado Springs by a friend of mine. I bought the edge connector converter and built a 1.5 Meg RAM disk off the cartridge port. Writing to the port is rather fun, i.e., there is no write line. The software for the I/O board handles this for you. Bob Vixie blv@hpctdlb.hp.com
