Don't use superglue. Top tip.

You can:
Use a gbs 8200 scan converter or equivalent to convert to vga.
Use a monitor that can display pal modes (eg, benq bl912).
Use hoglet's new dvi/hdmi converter with a monitor that has an hdmi/dvi input.

Yes I was looking at the BOM and wonder which to order. But assume with the exception of fitting under the Beeb this is just personal preferencance. The straight will fit a standard cable better as the connector is at right angles to the cable. The right angle will plug directly into the AP5. You w...

Only the mini fits under the beeb (and only the beeb, not the master). Straight through hole male for cable dangling: https://www.domesday86.com/?page_id=409 ... _Materials

But the right angled can be used for the AP5.

Glad it's working! Only "enhancement" I'm intending to add is the dacom compatibility mode and eeprom saving of various settings. If anyone wants anything else I would encourage them to contribute it

Duncan, I'm assuming it's a character in your password that's different on the beeb... No idea what though. Once the WiFi is set up the esp12 remembers it.

Use commstar version 1.4. Once connected change from terminal to viewdata mode and ensure you press I and change the speeds back to 2400 before pressing C to enter chat mode again (ie connect to the modem).

Commstar 2 won't work.

Fork the repository, write the relevant code, upload it to your repository, and make a pull request? :) At which point I can pull the code in and merge it with the master source? Re. "other NC in cable" - this looks like a modem, it's up to the end user to decide how to connect it to their computer....

Use esptool.py to completely erase the flash, then start again:

It's the ESP8266 on the NodeMCU that's not 5V tolerant. Max3232 can work over a voltage range, and converts ~ between 3 and 5V to 12V and back again, MAX232 is just designed to work at 5V. http://www.ti.com/lit/ds/symlink/max232.pdf -> it's why I used the 3237 (same as the 3232 but with more transce...

Right - so - the firmware in the main repository is designed to work with the new hardware - if you check the releases page, there's the last version that I had working nicely with the lolin setup. On a more positive note though, if this one works with the lolin board, that's all to the good. Have a...

RTS/CTS will need uncrossing too. Wiring is as per: Edit: You can turn off hardware flow, in which case those lines are just ignored, but it does reduce reliability on the beeb end at higher speeds.

"uncrossing" will involve a 9-pin to 9-pin, or 25-pin to 9 pin.. Ergo I'd have thought you may as well just build a straight through RS232-25pin-male to BBC 5pin and only have one cable in the chain. I'm only using a 25pin to 9pin adapter as I'd already built a straight through beeb->9pin, and I'm a...

I'm anything but a football fan, but I've quite enjoyed this little stint

Yes, and no crossover needed as the rs232 is wired up as a modem's would be (ie DCE). You need a crossover if you connect two data terminals together (ie computers).

(and yes, all five pins are connected to give hw flow control )

That's fine - you're just pulling/biasing/somethingerising a line. I remember doing this and thinking it shouldn't be measuring zero, but it was, and it was and it was fine that it was

This thread is from 5 years ago!

In theory RAMFS shouldn't bother it as it can't deal with the ADFS/Acorn DOS formats so it shouldn't be involved. That said, I did have some issues at various points with the IDE patched ADFS and the datacentre - unzipping files very often corrupted the hard drive. I never got to the bottom of it :?...

It was designed to fit into this slogger rx case which basically stuck the guts of everything, elk included, into a box and used the elk's keyboard on a flying lead. I don't imagine many were sold. It's a very large board and not very stable as it's uncased. Anecdotal reports suggest the connectors ...

You're fine

I suspect the bus will die with that much attached to it.

Cartridges, not ROMs. I believe slogger allows extra cartridges. Looking at the one on Stuart’s webpage. It does, but it's a horrible kludge of a device. However, the content of any ROM cartridge can be stuck on a ROM chip? Obviously not hardware cartridges, but I can't imagine anyone trying to run...

They're not the most reliable things - best solution is an AP6 in a plus 1, with that you can basically "fill" every single available ROM slot.

Great work Dave - I'm happy to build a couple. Anything but beebscsis

What is the speed like? Is it like waiting an hour for page to download? I have the original closed source WiFi board but not had chance to test it yet. I'm running at 2400bps, 9 bits per character (8N1) ~ 1000 characters per page = 9000bits, 9000/2400 = 3.75 seconds per page. In practice it feels ...

Viewdata's viewdata - using commstar, return is #, * is * and numbers are numbers :D Added bonus is that the hardware you're using to view is authentic. Re. beebscsis - too late I'm afraid! :D Go to jlcpcb.com, take the gerber files from the beebscsi repository, drop them onto the order form and you...

Just for posterity, bodging required: But we are working, complete with jumper selectable hardware flow control, thanks to hoglet
