Hi Morgan, Can you measure the current draw?? Should be about 200mA I think?? If it's too high, try removing the UART chip, it may be faulty? Try other chips, remove one at a time. If you are in

Hello everyone, hope you're having a fine day! I just picked up this kit a few weeks ago and I haven't been able to get the SIO card working. The front panel and CPU card work fine together but if I

Thanks Josh. Modem works fine with a PC dialing into the BBS so it’s not that. I found another CP/M modem program to try. I also got the 32k RAM today so I might swap that out as well and re-enable

Rich, I guess next step is try the modem on your PC terminal.?? Searchlight BBS? Cool, I used to run a BBS in the late 80's on Searchlight.? Frank LaRosa was the guy that made Searchlight.? Why

I had time today to try the handshaking loopback on the modem side and there was no change in the outcome. It will connect but do nothing. Hitting a key causes a disconnect. I rebuilt the BBS server

Hi Josh, Thanks for the clarification. I confirm it works fine. Best Regards Paul

Thanks for the info on the 4-Port LAN adapter.? I've sent Terry an email asking about it. David

Good point as always. Need to dig out my break-out box for that. Get Outlook for iOS<https://aka.ms/o0ukef> ________________________________ Sent: Tuesday, August 25, 2020 9:42:21 PM To:

Might want to try looping back the RTS/CTS and the DTR/DSR pairs on the modem.? That might fool it to work with 3-wire RX/TX/Gnd RS-232

Thanks Mark. I never inspected the modems I have, but it’s worth a look based on your experiences. Get Outlook for iOS<https://aka.ms/o0ukef> ________________________________ Sent: Tuesday, August

Rich, I had a number of Optima 144 modems, and they all had severe PCB damage from leaked surface mount caps--more damage than I had the patience to try to fix. I was able to rescue/preserve a Hayes

Yes. Synchronet 3.17 running on XP, which is Telnet only. It uses “COM-to-telnet” bridge software to support POTS. I had a spare PC handy so I set it up as a quick test to give the Z80MC something

rich: synchronet is running on a PC? ________________________________ Sent: August 24, 2020 7:57 PM To: [email protected] <[email protected]> Subject: Re: [Z80MC] SIO and Hayesmodem Just a quick update on

Just a quick update on this. I have a BBS (Synchronet) running enough that I can dial-in from another PC and connect properly. I started with the Hayesmodem 300, which was painful, and then changed to

Hi, I'm using his "P112-4 Port LAN" card. http://stack180.com/P112%20Photos.htm#4PortLAN http://stack180.com/images/P112-LAN.JPG "The production 4-Port LAN adapter provides 4 LAN-based 10/100BaseT

I have p112 and a question about "Terry’s Ethernet p112 serial adapter board".? What did you get from Terry's site to connect the p112 serial to the Ethernet?? Just the "LAN Terminal

The last several are good examples of how you can get from the 'net to a old school system being CP/M based on a PDP-11 that is sans native networking.? The interface between the network and the 80

Hi, I telnet to my p112 cp/m system console, via Terry’s Ethernet p112 serial adapter board. It even automatically powers & boots upon establishment of the telnet session.

Chiming in here: I still use LINKSYS WRT-54G wireless routers running DD-WRT. They all support TELNET logins (port 23), which is the insecure predecessor to SSH (port 22). I use TELNET to log into
