Re: OPERATIONS UNDERWAY TO RESTORE PAYLOAD COMPUTER ON NASA'S HUBBLE SPACE TELESCOPE
The radiation-hardened processors tended to be 8-bit back then. MIL-STD-1750A was 16-bit, but I'm not sure if it was mature enough back then. The testing of processors for aerospace is huge task. The more complex the chip, the bigger task the testing is. And then there is current consumption...helicon wrote: ↑Mon Jun 21, 2021 1:17 pm64k huh? Same as a commodore 64.

"Daisy, Daisy give me your answer true...I'm half crazy for all for the love of you...
And due to the extensive testing, the radiation-hardened chips are very expensive. Think about it: if a couple of engineers run tests for, say, 2 years, and then 20 pieces are sold...
I was in a project where we made an independent dependability study for MSG (Meteosat Second Generation) satellite platform. I got to read Ada code and MIL-STD-1750A assembly code.

Depending on the nature of the "device", a repair might not be impossible.Servicing Mission 4 (SM4): May 11-24, 2009
... Additionally, a device was attached to the base of the telescope to facilitate de-orbiting when the telescope is eventually decommissioned.
