@aka_pugs 4 MB must have been a huge amount of memory at that time.

@aka_pugs There is a retro RasPi version that I totally crave.

@aka_pugs in 1987 my college was still using one. Default password was pass. Found unassigned accounts and had fun.
Coded a version of Patients/Solitaire on it and one day went into the computer lap and everyone was playing it. #i May have negatively affected the grades that year.

Edited to change 1087 to 1987

@hmallett @aka_pugs My first computer had 16K in 1982. No Unix, sadly. Unix wouldn't appear in my house until the 90s, via NetBSD.

@chris @aka_pugs ha, that's incredible! Thanks for this.

[chris@mastodon.mihalis.net]

@stevenray @aka_pugs I never spotted until today that one of the photos on this website shows Ken Thompson (the father of Unix) with a pidp-11 he assembled. That makes it as legit as could be for running Unix

[stevenray@sfba.social]

@chris @aka_pugs yup, saw that and I thought so, too!

773110 is burned into my brain

[peterhoneyman@a2mi.social]

@aka_pugs hmm, my recollection is 128k

[paul_ipv6@infosec.exchange]

@peterhoneyman @aka_pugs

boot from tape or different type of disk?

[peterhoneyman@a2mi.social]

@paul_ipv6 @aka_pugs

I forget. I think we had an RM-80 (maybe?) and two RK-05 removables

[aka_pugs@mastodon.social]

@peterhoneyman @paul_ipv6 RM-80 was after my time.

[flux@wandering.shop]

@aka_pugs yeah, but not 4MB per process

[larsbrinkhoff@mastodon.sdf.org]

@aka_pugs The 11/74 was cancelled because it was to good compared to contemporary VAX models.

@paul_ipv6

I guess these switches were, among others, used to read and write memory.

I had to program this computer in binary (not assembler, binary) when I learnt computer science some years ago.

In my memory, the keys were shades of blue.
