I do. Several tubes of 8755A, 8155A, 8156A and 8085A and some A-5s.
Those parts are not that uncommon and they did have multiple vendors.

Most of the Z80 (2.5 ->8MHZ) and peripherals are available from 
many vendors including JDRmicrodevices.  Not all the peripherals 
were availble to 8mhz though (DMA was never made faster than 4mhz
if memory serves).
