Another satisfied customer with my #ASR33 controller board (and free 3D printed answer back drum).
-
I was wrong about my #ASR33, the re-crimping was fluke, it was random.
I took apart (hard work) to find that decoder clutch was not tripping, so it is not a BREAK at all, but the print drum was spinning on anyway.
Further investigation (by poking with a finger, not ideal in a moving mechanical machine) identified the end stop for the print drum was not catching all the time.
I "tightened" the spring (twisted the loop with fine nosed pliers). After, of course, losing the spring.
All OK now.

Panic for a bit...
I updated code on my #ASR33 driver, and screwed up as it is an old ESP32-S1 which crashed. Simple to fix.
But I figured, why not update to latest ESP32-S3 board. Did that.
Constantly showing break, "constant chatter of NULL characters", well, mostly, occasionally stopped and worked for a bit.
Tried old s/w, no joy.
Tried another new board.
And another...
Fixed old board and put back, still no joy.
Finally, re-crimped the connector.
Phew, that simple. Working again.

OK, call me mad, but I have ordered a handful of these. They'll be on sale in a couple of weeks.
This will be a very specialised and limited market I feel 🙂 and not make me any money (C.M.O.T.RevK again).
Tempted to throw in a 3D printed custom answer back drum with each order though...
It was definitely a fun project though. https://youtu.be/IrIK8SgE8c8
P.S. Self contained Colossal Cave Adventure is included 🙂

#Retrocomputing My first experience with "computers" was as a deaf kid being bludgeoned by computer assisted instruction —spelling and arithmetic drills. Acoustic modem connected to #Stanford. In my first ever #ActuallyAutistic #DirectAction I broke the #ASR33 teletype. "The button said "Press To Start". Pressed it into the chassis. (Haven't played the innocent as well before or since).

I keep forgetting to link to the game! Set your telnet client to use ^H as backspace, then telnet to frieltek.com:2323. Press ^M^J to get the login prompt. The type in HEL-T001,DNDTST,2 and press enter.
Enjoy!Message me if you have any problems or would like your own account on the HP2000/Access TimeShare BASIC system. "For the love of Vintage computing!"

I fixed a couple more bugs in the DnD game on the HP2000. Heal was broken, and the FD 'Fight to the Death' mode basically just killed you. Oops. These were typos when entering that old text code into the system. On the upside, it is very stable and working. Now to start smoothing out the text display and remove some of the testing 'you are here' stuff I put in to debug it. There is no debugger in the HP2000 BASIC!

Success! I have the HP2000/Access TimeShare BASIC version of DND running! I have it setup so you can Telnet in. Here's how:
1. Set your telnet client up to use ^H for backspace (I use PuTTY)
2. Telnet to frieltek.com:2323
3. Press ^M ^J to get the login prompt
4. Type in HELLO-T001.DNDTST,2 and press Enter.
5. Enjoy! -
Made some nice progress today on the DND game running on the HP2000! I actually found the limit on code for any single program, so I had to split the main DND up with a second program that can be CHAIN'd into and then back again. Think of it as putting the GOSUBs in another program and then returning when needed.
If you have Telnet (and why wouldn't you?) and want to see what this is about, DM me!

Dnd Game Update:
Yesterday I filled in the list of 30 monsters that an adventurer can encounter. I tried to rank them from easy to hard. Now I have to modify the probability tables for hits per weapon and defense per armor type.The game is playable, but I am finding bugs in the code. Imagine that from 45 year old BASIC code!
Looking for helpers too!

@crash Like, they need BBS type access? Having dealt with everything since 110 baud, I can recommend a BBS system that is accessed via Telnet. I've even setup my ASR33 Teletype with a WiModem232 to access wifi and provide telnet access to the world. Works great! If a teletype can do it, any PC with a serial port and a communications program can do it.

I have a pair of vintage terminals I've hooked up to wifi to my hosted HP2000 emulator. Good times! #ASR33 #DECwriter -
Now that there is a complete HP2000 TSB emulator available, I've put it online on the Internet and have all the code I kept for DND typed in. I'm just missing the code that probably encompassed the initial instructions, and the base code to configure the items used in the game. If this is something you'd be interested in helping with, please DM me and I will create an account for you on the system.
Also, please BOOST this!

One happy ASR-33 on the Internet!

@ef1j Yep, now I just have to dig out the manuals and figure out which one is the 8th bit. Which is weird because I don't think that the keyboard is supposed to be able to generate all 255 characters. I'm going to email Wayne as well and see what he says too.
-
@ef1j95 , Do you use the #WiModem232 on your Teletype? If so, what baud rate did you set the wimodem to? Now that I've had my #ASR33 restored, I can communicate to my 5150 PC with a null modem cable if I set #Qmodem to 110,7N2 and everything is fine. If I select 8N2, all characters from the 33 have the high bit set and I don't know if this is correct or not.
Thoughts?

For some reason my #ASR33 has an extra relay (looks much more modern). It appears to be fed from pins in a spare plug at the back. I have traced what it does. It switches if tape reader works in local mode or line mode. Default local mode only. Weird. Changed to line mode now!
