OT, but electronic

Ah, yes, the days of the 3-pass paper-tape compiler...

I was thrilled when finally got a rotating drum and could get away from all mass storage being 7-track tape...

I've saved all the replies. Thank you all.

But I'm not going to do anything until the next time it doesn't work. I realize now that I wasn't clear -- I apologize -- but I actually wasn't asking for help, just telling you how it stopped working and then seemed to work again after being without power for a while. I thought that would be an incident useful to know about.

I should add, that before I turned it off for 90 minutes, I turned it off for about 30 seconds and it didnt' work when I turned it on.

And that months ago, I had turned it off for only 5 or 10 seconds on occasion and that it would work fine when turned on again.

So it seems like being off-power for 90 minutes really helped.

If it had just stopped working, that would have been less interesting, but I thought the 4800 connections the night before were interesting.

It's still working now. I disconnected and reconnected once since I first posted.

Thanks again.

I had a PcJr. for like 11 years, but didn't have a modem until maybe I borrowed one the last month, and had no one to call.

I think my first modem I used was 1200, and it was fast enough for email and usenet iirc.

I forgot to say that too. This wasn't a first generation modem, it was

56K v.90 or 92.

75 and 150 baud - old Model 33 teletype modems. I are official old. :-D

Yours aye, W. Underhill

It was rough. And the fighting with the Indians.

Some of them had Winchesters with DOS 4.

I was up to the 2400 before Usenet was available to me. The 300 was adequate for RIME and FIDO BBS .

I remember when the "experts" said 1200 baud was the maximum speed that could ever be achieved over regular phone lines, that it was physically and logically impossible to go faster.

I seem to recall a 75 baud in the early 70s for printers, which were the terminals back then. (There were vicious arguments over which was better, a hardcopy terminal or a CRT. I always wondered what happened to those hardcopy people!)

Pish. I remember the 256k sticks as new and hi-tech- a big leap up from the tubes of loose chips we had been using- first 9 chips (for $30) to make a

64k bank, and then the leap to 9 chips making a 256k bank.

I used to keep a 'visual aids' drawer at work with samples of all the generations of memory chips, and of CPUs, to show to new kids coming in. One day, some self-appointed arbiter of stuff to keep (stuff she used) vs. junk (stuff she didn't recognize) pitched it all. Some people are only alive because killing them isn't worth doing time over....

Well, if we're remembering, I remember when all memory was core...

IIRC, the Bell 212A standard (1200 BPS) was designed to not work well with acoustic couplers like 103J (300BPS) was.

[Mark Lloyd]

I remember getting my first "high speed" 1200BPS modem.

[Mark Lloyd]

When I bought an extra 24K for my VIC20 (about 1983), it came on a big cartridge (12 big RAM chips and a couple of decoder chips). It cost $150. That's more than my more recent purchase of a 512MB PC3200 module.

[Mark Lloyd]

I remember that 300 would receive text nearly as fast as a lot of people can read. That is, if you don't have to stop to figure something out, as in one place where someone confused "gravity" with "gravidity".

[Mark Lloyd]

I found the following baud rates listed in some UART documentation:

50 75 134.5 150 300 600 1,200 1,800 2,400 3,600 4,800 7,200 9,600 19,200 38,400 57,600 115,200

A 6SN7 sounds like a good triode for making flip flops. Just would not want to wait for my computer to "warm up" before I could start computing...... (-:
