I received this from Al at mtuxo!aed. Since I don't know if I can copy this information I suggest getting in touch with him directly for more of this info. I also received mail indicating that IBM makes an IEE488 card, but no specific information was supplied. ---number 6--- IBM also manufactures an IEEE-488 interface card for DOS pc's. Pt. No. 6451503 - General Purpose Interface Bus Adapter - $395 6024201 - GPIB Adapter Programming Support Sfwr.- 245 I haven't seen anything for the 3b's or the 7300, yet. ---number 7--- For the 6300, at least, IBM sells a PC GPIB adapter for $395, and some support software for $85. It's in the standard PC catalog. I've looked at the hardware manual, and the card seems reasonable. It is supposed to be able to do DMA at 300KB/sec on an IBM PC. The only add-in of any sort for the 7300 I've ever heard of is an expansion disk -- I gather that AT&T is not as forthcoming with the internal interface specs as they might be. It's a shame; I'd buy one if I didn't think I was completely at AT&T's mercy for my peripherals. ---number 8--- National Instruments also does work on the 488 bus. They have cards for all major PC's so you might want to try them for a 7300 card. ------------------------------------------------------------------------------- Thanks to all who responded! -- Robert Switzer - AT&T Information Systems Rm 2J208, x7281 Holmdel, NJ
