Some old pc stuff findings from attic :)

Recommended Posts

Was cleaning attic and these popped in one pile (still piles to look there) I trowed a lot of things on pin but these I kept. Will see what else finds there is. :)
These are stuff I used, not just collected. Did read that manual well back then.

I have to do the same while I have some old computers still functional here.   :)

 

I also have 3 generations of backup tape drives to copy data from.  I had to quit on the last one when it quit reading the "end of tape"  pairs of holes. :o  If it does an automatic re-tensioning when i try to copy the data, then I am really screwed!  Oh, wait a minute!  I probably still have the little hard drive that it was safeguarding.  I have never thrown out a working hard drive, no matter how small!   ;)

 

I lost my last copy of PC DOS 1.0 when I lent the 5.25" floppy it was on to somebody to play an old ASCII game.  "Bugs!", I think it was.

 

 

I would have to underclock my current machine to play some of those old games again.

Use DosBox, you can setup the cpu clock for older stuff

My first hd was 8Mb 5,25" full size in -89 and same year did get my hands on 20mb st-225 :) and fiddling with 360kb floppys :) in xt pc some ~6mhz turbo. Autocad was bit slow and did not run without math prosessor (I did use emulator) did not buy that math prosessor couse it was costing nearly as my pc. Still have working quantum bigfoot 5,25" HD 1,2Gb  and 1,2mb floppy on working pc :)

Very nice! I work on restoring vintage computers when I have the free time. I'm sure my attic needs some cleaning, there's some Pre-8086 through P4 era stuff up there. :crazy

 

Most of my 51/4" floppies were 160K, formatted for Apple ProDOS and/or SOS. I have a few 360K's for a Tandy 1000HD though, which runs MS-DOS 2.11 on a 5MB Winchester style hard drive if I'm not mistaken.

 

My latest project is my Amiga... now that's gonna be some good fun!

I forgot all about that little problem and Xernicus's "Winchester" HDs.   :)

 

I discarded my first modem recently, a 300/1200 baud.  I marvelled at how large the parts were!  Man, did that 1200 baud save money on CompuServe's pay-by-the-minute fees!

Thanks! :)

Oh... u remaind me... I saw little box in attic where is some old modem which used 9v battery. I'll try find it again tomorrow and take some pic. In 1987 I was taking cource for "telecom" and we connect to cern (not many points to connect back then openly). I was my first digital connection and was bit more complex and simple looking than now :) I think it was 1200baud modem.

:) I think it was 1200baud modem.

 

For all you youngsters here, 1200 baud is about 0.0012 Mbs, at 1 bit per baud.  My 100x100 pixel avatar-pic would take about 10 seconds to receive, with 2 bits added to each byte for some simple transmission protocols.

 

Ooops!  I forgot about bits per pixel.  10 x 24 = 240, so make that about 240 seconds, or four minutes.   :)  ASCII-porn, anyone?

 

The 9600 bps modem was also 1200 baud, but used 8 bits per baud.   :)  ( 0.0096 Mbs ).

Added modem pics :) remember why cutting line after transmission was needed, phone bill after one nite can be huge.
