Making a PCjr Serial Port Adapter for a Serial Mouse
by Dan FitzGerald 24 Mar '24

24 Mar '24

I'm cross-posting this here from the VCF Forums, because its been two days and I am still absolutely stuck on this. I have a working Microsoft serial mouse that I have successfully tested on my 5155. I have a PCjr. I made a DB-9 adapter for the RS-232 serial port on the PCjr. I plug my mouse in, and the Microsoft Mouse driver recognizes it, mouse test software indicates that it can register left and right button presses, but I can't get the cursor to move! Is there some sort of secret that I don't know about? I've checked my connections with the multimeter, all are good. I'm using a DB-9 male adapter on one end and a 2x4 berg connector on the other end. This is the pinout I am using: PCjr RS232 pinout (direction: you are staring at the back of the PCjr): 1 2 3 4 5 6 7 8 A (XXX) (DTR) (RTS) (TxD) (DCD) (DSR) (CTS) (RxD) B (GND) (XXX) (XXX) (XXX) (XXX) (XXX) (XXX) (XXX) This is the pinout of the male DB-9 plug (direction: you are staring at the plug): 1 2 3 4 5 (DCD) (RxD) (TxD) (DTR) (GND) (DSR) (RTS) (CTS) (RI ) 6 7 8 9 Note: Pin 9 is not wired, as RI is not used on a PCjr's RS-232 port. And as far as I can tell, this is what is supposed to be the pinout of a Microsoft Serial Mouse (Female DB-9, direction: you are staring at the plug): 5 4 3 2 1 (GND) ( ) (TxD) (RxD) ( ) ( ) ( ) (RTS) ( ) 9 8 7 6 -- Regards, Dan FitzGerald They/Them or She/Her Classical Computing Laboratory at IBM-Poughkeepsie http://www.vm.ibm.com/devpages/dfitzger

Re: [vcf-midatlantic] 2 PAL TVs needed for VCF East 2024
by Jonathan Sturges 24 Mar '24

24 Mar '24

> I have 2, but it couldn?t hurt to have a backup. Can you please bring to > VCF East? This reminded me to check on a converter in my stock, the Kanex Pro CON-AV-HD4K. Sure enough, it converts PAL, NTSC3.58, NTSC4.43, SECAM, PAL/M, and PAL/N on composite or S-video up to HDMI 4K. It's super-small so I'll bring it along too. -Jonathan

We need a few more volunteers for A/V to help lighten the load and give them breaks. Besides setup and breakdown, it is mostly monitoring the recording on the computer. Training will be provided. We also need an MC to introduce speakers. We also need a microphone runner to go to people when asking questions so that they speak into the microphone. Fill out the volunteer form here: https://docs.google.com/forms/d/e/1FAIpQLSeF33aZBQL57vymsP98JWazK1h1IcHHqbM… Thanks! Jeff Brace Vintage Computer Festival East Showrunner

consignment system questions
by James Murphy 23 Mar '24

23 Mar '24

Hello, Can someone provide some "more basic" basic information about the consignment system? Is it possible to browse items? Are items required to be in the consignment system before they can be sold at the meet? What about haggling? I guess I thought this was just an index of items for us to peruse but now I'm not sure. Thanks!
