I'm curious about my Xebec S100 SASI host adapter. Most of it is 74LS TTL chips and it runs fine with a 6Mhz Z80 processor card in the bus. When I go to 8Mhz, then things break down, it will access the hard disk some, but eventually hang. Could it be possible to swap the 74LS chips out with faster 74AS chips and gain the ability to operate at 8Mhz? I don't know if this line of thinking has merit, anyone here have insight?
Thanks!
