Parts for Allergan Humphrey (vision field analzyer)

Model 605 by Allergan Humphrey, Instruments/a SmithKline Company Field Analzyer That thing landed at our TV shop with insufficient vertical complaint. (I see it this way as rolling and grabage video). Computer inside is very on topic and old! Intel 8088, 256K, 6845 video with pair of RCA 6264 ram for video etc, small handful of PALs and load of TTL ICs. I used to service TTL stuff like Z19 terminals XTs stuff back in very early 90's at university. So I rubbed my hands in glee because this is my area! Figured out the CPU is "dead" because of no clock feeding it. Hence the grabage rolling vertically and insufficent vertical scan on the monochrome CRT. I noticed that unit has ROM for CPU is missing but that doesn't explain no activity on the CPU even without ROM. I need to be double certain so need older data sheets. Googled for 8088 pin out and I was disappointed. Need to get info. I'll post both photos of that unif and list of IC I need data on them tomorrow night. Cheers, Wizard
