I assume that was due to its being stocked with 150 ns RAMs. Can anyone verify this? What speed of RAM chip does work with an 8 MHz Zip Chip? (2) Also, can a Transwarp access the Memory Card at full speed (given the 120 ns RAM it needs)? (3) Are the Zip Chip and Transwarps DMA compatible? More importantly, will they work with the Apple Hi-Speed SCSI Card? E-mail or post responses as you see fit. -- Eric Hsu ehsu@husc4.Bitnet, ehsu@husc9.harvard.edu Brought to you by Super Global Mega Corp .com
