Suggestion to speed-up QDX serial port development
开云体育Hi all, for those who are as eager as me to get an extra serial
monitoring port for the QDX in a future firmware release, here is
all my humble technological knowledge allows me to contribute to
this end at the moment ?:
Have a good laugh and a nice Sunday ... and don't miss to contribute heavily ???. Vy73 Stefan. -- Stefan U. Hegner <db4st@...> * * * DB4ST --- German Ham Radio Station D-32584 L?hne ----- Locator JO42IE * * * GPG-Key | C3CC 23A4 FBA8 622B 48AE F-Print | 4F19 D0EE E39E ABDC 2BCE |

Here is the terminal I coded Macro-11 on as a teen. I wrote diagnostic software for the Trapix-5500 image processor while working at RCI. $1000 is insane.? Colin - K6JTH On Mon, Aug 8, 2022 at 11:36 AM Giuseppe Marullo <giuseppe@...> wrote:

Wow, especially: "“Powers on, CRT does not start, AS IS.”"

开云体育I'm not sure of the seriousness of the need for VT220 monitor, but cannot serial port software emulation of the VT220 accomplish the necessary if needed?I cut computing teeth on the VAX line of computers, and used both hardware and software VT100/VT220 over the years (even the old HyperTerm provided with early Windows worked sufficiently).? PuTTY also offers emulation. 73 de Daniel KB3MUN On 8/7/2022 10:21, Stefan U. Hegner

Hello Daniel This is a philosophical point.? Naturally we don't "need" a VT220 terminal. Any terminal emulator does the job.? But "Need" and "Want" are not necessarily the same thing. Every single one of us here must be familiar with this concept. Almost everything we do with amateur radio is unnecessary. We do it because we find it cool, we enjoy it, it's interesting, we learn from it and it makes us happy. The exact details vary from one of us to the next.? That's how it is for me, and the real VT220.? 73 Hans G0UPL http://qrp-labs.com https://www.buymeacoffee.com/g0upl -------- Original message -------- From: "D.

Oh dear... seeing VT220 mentioned took me down the nostalgia terminals trip...
ASR33 on a DEC-10 at university
ADM3A on Prime750 at university. (? 32bit supermini similar to a VAX 11/750 but completely different )
Televideo 925 on Sage IV micros ( 68000 Unix / CPM-68k machine )
Kokusai KDS7362 on Sage IV micros ( 68000 Unix / CPM-68k machine )
CIT-101 (Poor man's DEC VT-100) on big Unix boxes or VAX 11/730 (I had the 11/730 to myself for 4 years!)
DEC VT-320 on a VAX 11/750 cluster.
The arrival of cheap 80386 based PCs early 90's blew the old minis out of the water for performance and that was the end of the glass TTY. I last used a terminal professionally in Summer 1998, so 24 years have passed.? That was on the 750 cluster which was
being replaced with a handful of Netware connected PCs. Even 24 years back you couldn't give away 80x25 or even 132 column VDUs. Nobody but nobody wanted them and I saw loads go into the waste skips, they didn't even go for recycling.? If I had only known
what they would be worth now. And had somewhere to store them. But this is from the man who junked an Acorn System1, Acorn System3, a Nascom2 and Data General Nova 1200 22 years back when moving house. Ha worth $1000 - $2500US to collectors now !
The question is: are people actually buying VDUs for $450?

开云体育Strangely enough, just ran across this picture of my Decwriter II (300 baud! ?30 characters per second!) that was hooked up to my S-100 machine running CP/M. ?Had one in high school that was a _serious_ upgrade from the KSR-33 teletypes (thought the teletypes had paper tape read/write mechanisms, so you could punch 5x7 alpha letters on tape with the appropriate program), and when I had the chance to buy one for my home computer, I jumped at it. ?8*) ?Just to be topical, you could hit <CR> on that or the VT-220 or VT-240 and it would be the console.? 73, Willie N1JBJ |

Nah, not really. I thought, it be the kind of gimmick we techno-nerds like, but anyhow, I had some fun fiddling with the undocumented API. ... but of course you are still free to contribute, we need to keep Hans spirits high to continue to get good kits & upgrades from him ... ?? - Here you go again, if you like: Vy 73 Stefan.
