I dug deep into the catacombs this past weekend and discovered some interesting ancient relics. Among them I found sound remnants of two Microcomputer Systems Corp/Xebec hard disk controllers that were recently mentioned and took some close-up shots of them. One is a single-board ST506 disk controller with GPIB interface, PCB assy# 104506 Rev 02, without the 8048 and EPROM. Front and back shots, JPEGs of 380 to 309Kb each. Much better resolution than the manuals show: Can see part numbers on most IC's, see where jumpers go and read color bands on resistors and chokes. Shot in daytime shade, no flash to reduce reflections and glare. Contrast is a bit low. The other is a 3 board assembly that might be a SASI controller with GPIB interface, sans 8048, EPROM and 9914. There are shots of front and back of each of the three boards and a shot of the three assembled. JPEGs of 360 to 380Kb each. Shot in daytime shade, no flash to reduce reflections and glare. I suspect that someone might find them useful or at least interesting to look at but I have no place to put them at the moment. If someone is interested in them, please do let me know. It would probably be best to ftp them to you, as I doubt they are small enough for mail. -- jd If you keep anything long enough, you can throw it away.
