My cube is actually in a raised floor environment, but I don't do any server or mainframe work. (From what I hear, the room was built as a HUGE server room, and then things got downsized, so they put up a wall and made part of it office space. Then, things got downsized again, and relocated, so they put up yet another wall, making a tiny server room, with some office space and a large storage area.)
Oh, and telnet != dial-up. ;)
All of that said, the oldest computer I've directly used is probably something in the Apple II line. I have indirectly used a PDP-8/E, however.

Didn't say it was... I was dialing up to use telnet... :psyduck:

Made for some interesting debugging sessions. :D

Same here! We must be of a similar age...

Could be. I'm 52. Ask me again in two months and the answer will be different.

But then again, that 64k was including the ROM containing the OS and the development environment. :D
Mi first was (you prolly guessed this from the 1K memory size) a ZX-80. Soon to be superceded by a ZX-Spectrum.

Well, you could always bank switch the ROM out. If you didn't want the OS or BASIC (or thought you could do a better job at the routines than Commodore did,) then you could load your stuff into RAM, and then bankswitch the ROM out, and get more RAM.
(Same trick for 64k on an Apple II, but smaller ROM, and there is still a 4k hole in the memory map that is for I/O, and can't be bankswitched out - the entire $C0-CF area.)

Yup, I remember that. :)
And it didn't take the community long to fugure out that you could actually do a bank switch trick on the ZX Spectrum too. If only Sinclair would've used working ratherthan defective memory chips. So... people started to use working memory chips, and all of a sudden, the ZX Spectrum would have a whopping 128k RAM! How were we ever going to consume all that? ;)
Sinclair's reaction to this was the Spectrum 128k. ;D
