Thread: DOS

Ahhh, DOS.

I loved it. They were the good old days.

You had a fast system!

Mine was a Z-80 based Dick Smith System 80 Business Computer (no cassette deck for data storage) with 64kb of RAM using NewDOS. My first modem was 300bps.

My first programs were on punched cards for use on the UNSW (ILLIAC, I think) computer in 1966. My first computer I used at work was in 1968, it was a HP computer with 4kb (yes, 4 kilobytes) of memory.

First computer: Commodore which had a tape to store programmes. Wow.

Second: Apple II which actually used a floppy disk to store programmes. Double Wow.

DOS came much later

There was of course different vendors of DOS such as DR-DOS (from Digital Research) that ran on the Intel 8080

There was of course: Microsoft MS-DOS and the IBM PC-DOS

My first computer (1983, I think), an Altos, ran CP/M. It had 8kb memory with a Z80 processor and two 8" floppies - which held twice as much as a 4.5" floppy. I still have it somewhere. Went from it to an 80286 running DOS - and with 10MB hard disk!

The first computer I had direct dealings with was one we started to use at work in 1972. It was a CDC Cyber 76 from memory. Input was punched cards, or a 40" digitising tablet, output was a line printer and a 40" pen plotter.

I still have my C.Itoh 8510 dot matrix printer from the 80s. It cost me $800. Anyone need one?

Today, I threw out my two Tallgrass 60Mb HDD/Tape Drive combos in a cleanout of my workshop. I also tossed out two brand new Actron Token Ring adaptors that ran off the parallel ports and allowed ethernet connections. (They are in my workshop bin if you want them.)

remember to park the heads,
My first business computer was (cant remember) ibm, had a hard drive and 5 1/4 floppies (they were real floppy). Taught all my kids to work in dos, I think they thank me. I still have early sets of dos disks in the store room (only looking the other day think I should throw them out. What about trying to work out conflicts with asigned com ports etc. Them were the days

mine was a modern 486 dxII 66.....

But..... i had to service the old computers in the Halifax and TSB branches back home and they still used the old Philips equipment with, yup, a 8" fdd, and to boot from it was combination 2-7-5 (2 clock wise, 7 acw, 5 cw) on a KEY SWITCH.....

and servicing the old dotmatrix printers was fun. Always very rewarding and frustrating all at once.



DOn't get me started on ATM machines over here tho!

1980 - DEC K10 or a PDP11/23 at uni.

Then I think it was either a TRS-80, IBM-XT, or DEC Rainbow. After that the list grows but mostly DEC equipment. But also ICL, Wicat, NEC, NCR, Fujitsu, Sun, HP...

I managed to come by a DEC Rainbow being discarded in 1991 so I guess that was my first home PC - dual single sided 5 1/4" floppies, 10MB hard drive, 896KB RAM 8088 + 8087 and 8-bit colour screen running MS-DOS 2.11 or CP/M.
