> the HC11 is a dinosaur Ah yes, it may be but some of us like dinosaurs! ;-) I started doing hardware/software professionally in 1978 with the 6800 and an Exercisor, back in the days when weekly phone calls to Texas were required to report the latest bugs :-) I think I found one of the last reported bugs in the 6800 operation. I stayed in that field until 1986; I moved on to "bigger and better" things but adopted the 68HC11 as a hobby and sideline business for bit crunching, automation control, etc., and I love that family of chips. When you are at home with the 11, you can sure make it stand up, dance, and sing! When I upgraded my home computer to an XP system at the first of the year, I couldn't connect with my old EVM. Since I had a 10 year old product that they wanted back in production, I had to dig my 286 system (my EPROM programmer) out of the attic. This past week, I went at the XP system with a vengence and a new app program from P&E and finally got the EVM up and running again. I have a stockpile of HC811E2 and HC711E9, enough to satisfy my needs for years to come. By the time my stock runs out, maybe I'll be too old to continue the hardware/software bit crunchers! It may be a dinosaur, but then so am I and dinosaurs love company! (she said as she reached over and patted the HC11 EVM) Calamity Jane

I remember loading up both the assembler and the editor on paper tape into the Exorciser via an ASR33 TTY!!! And yes I also love the HC11 ...BUT....I'm cheesed off with Motorola and they have lost my loyalty and confidence. Commercially, as far as I'm concerned, they are not offering me any more than any other chip manufacturer and since loyalty to their clients is not one of Motorola biggest virtue of lately I'm no longer inclined to use their chips if it doesn't suit me. In fact they have done me a favour by no longer supporting the HC11, since I have been able to look around and see the benefits of using other company's chips.

Printer! bloody luxury! I had to build a 130 VDC power supply so I could get a model 35 teletype to run on the current loop of the MEK6800D1! The whole floor vibrated when I printed a listing. To get programs in I had to read in paper tape. When I got the MSAM cross-assembler it was so many punch cards that I nearly got a hernia. And then I didn't have a FORTRAN compiler on the same machine as the card reader - I had to read them in, punch paper tape, and then read the paper tape into a machine where I could compile the cross-assembler! And when you tell these young folk how hard we had it, they don't believe you ? cheers, Nigel At 21:19 03-08-18 -0400, you wrote: >In a message dated 8/18/03 7:25:05 PM Eastern Daylight Time, > writes: > >I hate to be pedantic, and I am probably showing how much of a Dinosaur I > >am, but shouldn't that be Exorcisor? >============================= >We were using 6800s at ECC in '76,77.

HEY.... This is great! We have found an almost on topic use for this list :-) As a young fellow, I was only allowed to use the Exorcisor when the R&D department wasn't using it and then at lunch time or after hours. One would get pretty depressed when, after loading up editor and assembler (+- 1 hour), the system would crash because the code just written had a bug and would kill everything.

I was impressed by the Exorcisor floppy ( 8 inch) though - our boot diskette had worn one track so much that you could see through the diskette. Still worked (good thing, as I don't ever recall a BACKUP boot diskette). Those bits were BIG: I think an 8 inch floppy held about 180K - or maybe that was the double density ones I seem to recall that the current loop driver was a little wimpy. Every once in a while we had to switch the ASR33 to local mode and pound keys to burn the oil and oxide off the contacts. I have sometimes wondered if the computer would have ever gotten past number crunching if it had been invented someplace with a complex writing system like China or Japan. A Teletype was a purely mechanical device - serial data conversion by rotating disk. Feasible for 26 letters (upper case only) and a dozen symbols, but pretty tough for a few thousand glyphs. It didn't take long after the first computer was born before someone hooked it up to an already existing teletype - and all of a sudden you could process text.

OK, I have got to chime in. Most people used DOS 3.1 on the Exorcisor. However, does anyone remember the earlier versions of DOS. I think that the rev. number was 2.3 or something, it was less than 3.0. This was when they used the 8 inch floppy drives and the operating system picked up the drive head between each access? That was really nerve racking to hear the floppy drive sound like a machine gun. Or perhaps a better description would be that it sounded like a car engine about to blow a rod.

> Those bits were BIG: I think an 8 inch floppy held about 180K - > or maybe that was the double density ones 128K I think - an IBM format IIRC. I still have one with my modified version of the "smallc" compiler. One disk could fit the source, another the assembly output, so it was possible to build it on a machine with two drives. The first 5.25" floppies (TRS-80?) only held 57k! Clifford.
