Oh well, The axp150 was the machine I used originally, so it's a bit
sad to see it go.

But yeah, good riddance. The lack of byte and word operations were a
fundamental mistake and made those early alphas very painful.

The design team obviously made other technical mistakes (sw fill tlb
etc, with memory ordering being the one that never got fixed), but the
byte were the killer for any sanity both on the IO side and the code
generation side.
