I not only remember them but have a complete set of the IBM model 5150 in my basement. It is hardly used and by this in mint condition. We got it when I went into retirement in 1992. It has been used in our demo center for the employees and I paid 50 $ for the whole enchilada. One of these days I will have to go down and test whether it still works or if some capacitors have given up. I actually bought my first one of these in 1981 while in the US. In 1982/3 we have been building our own extension cards with 512 kB of memory which was a memory size the big /360 systems did have in the late sixties. Everybody shook their heads.

Sold IBMs for a while at $8,000 to $10,000 a piece, two floppy drives, the IBM boot disk, a box of 10 floppy disks (cost $100 per box, 360K per floppy) and included half a days training. The government systems came with a version of DbaseII, direct from Aston Tate. Made a 15 percent margin. Also most of the government machines needed an Attachmate above board ISA card (about $1000.00) so the PC could also work as a dumb terminal.

Am I really the only one remembering the original IBM PC XT and its ISA add-in boards for just about anything: RAM, floppy controller, harddisk controller (MFM), RTC, I/O, and graphics (monochrome or CGA)? /gustav -----Oprindelig meddelelse----- Fra: dba-tech-bounces at databaseadvisors.com [mailto:dba-tech-bounces at databaseadvisors.com] På vegne af Jim Lawrence Sendt: 6. februar 2013 16:04 Til: 'Discussion of Hardware and Software issues' Emne: Re: [dba-Tech] Web RTC built in Hi Gustav: True but to having full audio and video as well as chat at your finger tips is quite an advancement. I am aware that it has been around for a while but just in chat mode...built a chat for a couple of clients but this is to the next level, with no third party (paid for) apps.

Every computer today has it. But it was missing on the original IBM PC (XT). If you didn't want to adjust the clock from 1980-01-01 every time you turned on the PC, you had to obtain and install a third-party option board equipped with this Real Time Clock. /gustav -----Oprindelig meddelelse----- Fra: dba-tech-bounces at databaseadvisors.com [mailto:dba-tech-bounces at databaseadvisors.com] På vegne af Jim Lawrence Sendt: 5. februar 2013 17:47 Til: 'Discussion of Hardware and Software issues' Emne: [dba-Tech] Web RTC built in FireFox and Chrome have both added new features to their browsers that will allow direct audio and video calling without third party applications or plug-in. The capabilities is now build right in the browsers. Along with the article is a small chunk of code showing how this can be implemented via web page and JavaScript. https://hacks.mozilla.org/2013/02/hello-chrome-its-firefox-calling/ I understand the both Opera and Safari have similar projects in the works but as always whether IE will follow the W3C protocol communications standards or go it alone is anyone's guess. Microsoft does have a large investment in Skype so this may predetermine their next move.
