During the 80's, I had the keys to work, so I had free run of the equipment, after hours. I used that equipment on my senior project, and wrote my college papers on the company's CP/M computer in Wordstar. I think I got good grades on my reports, not for the content, but because the margins lined up on both the left and right side. The company had Tektronix development systems for working on microprocessors. An 8002 and a 8550. School had a lab full of HP 64000s, which were always occupied. Both the HP and Tektronix units cost well in the 10's of 1000s of dollars. By the mid-80s, however, emulator pods, that plugged into an IBM PC, started to become popular. Those sold in the $2K to $5K range. By ~1990, the IC makers started selling evaluation boards, for only a few 100 bucks. I picked up a Motorola HC05 EVM board for under $500, and it worked well as a development platform. Of course, now I use AVR tools, that cost less than $35. I own a programmer than can do MACH devices, and it cost me in the ballpark of $200, back in the early 90s. I haven't used it in years. Haven't erased an EPROM, or quartz windowed uC (usually an HC05-C8) in over 20 years. Don't drop a ceramic quartz windowed 22V10. They break in two, when they hit the floor. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
