My brother and I have been messing with our IBM 5150 and doing cool stuff with it. I got it to play a youtube video via telnet via my bro's mac via mplayer with libcaca (ascii video output) + youtube-dl (a youtube downloader. The mac is doing all the heavy lifting, but it is still cool to see these images on a IBM 5150, just by typing a few commands on that old keyboard... more fun projects to come with this old thing.

Eureka! The IBM 5150 is on the internet!

!rant I'm beginning my nerd project of getting my IBM 5150 to the internet via my raspberry pi and a terminal emulator. Oh and the IBM has a 4gb (yes gigabytes) HDD in the form of a compact flash.

The pi is a model B. Even as an older pi, look at the difference in size versus performance!

The 5150 is 4.77 mhz

The Pi is 900mhz

That moment when you realize you're using a Hackintosh with VirtualBox and a CF card to install a Beta version of MS-DOS with DOS SHELL that your brother found on an old BBS forum; on an IBM 5150 from 1981.

Well, I'm still in 1981 Hell as far as serial connectivity goes, but we got boobs on the screen, because when we're working with DOS 5.00.2 BETA and 4 colors at a time, why the fuck not?

Operation PiBM 5150 XT is continuing this morning!

Rantberry PI

Thinking about making this into a terminal that accepts a serial connection from my IBM 5150 PC for that Chroma Green authentic text based experience. ;)

Seriously though. How awesome would it be to use a circa 1981 IBM 5150 as your terminal? Lol!

My IBM 5150 doesn't have the standard IBM Asynchronous Card in it and was replaced with a Tecram First Mate multifunctional memory expansion, serial connectivity, and printer parallel card. It has more jumpers than a suicide hotline.

Frustration Rant!

Because old hardware means learning the hard way sometimes, I've had to purchase more goodies.

On my last update, I installed the rs232 shield which may have inadvertently been wired backwards for Tx/Rx from what im used to. I assume it is backwards to most db9 serial ports because most Arduino or other projects you would do with a pi have serial "in" connections like old routers and devices that would be "controlled" rather than the other way around. Anyway, according to a video on youtube showing a guy turning an old machine into an IRC client via raspberry pi, this shield may be swapped. That means that instead of interfacing with the old machine via a null modem crossover cable, I need a straight cable with male db9 on both ends. I unfortunately tried using the null modem crossover cable which was reversing the reversed pins all over again. I hope these next few days are more fruitful now that I've bought a straight cable and db9/25 adapter.

The good thing is that I managed to get the pi to recognize its new serial port. I also dusted off my DOS skills and my serial card in the 5150 seems to work.

I literally banged my head after nothing worked. Im hoping that the tx/ Rx is solved soon.

Oh and that AT to PS/2 adapter will allow me to use by IBM original Model M Keyboarf rather than the fun model F.

!rant seems that my raspberry pi serial idea is a little bit complex at the moment and may take a more serious turn later, but I have studied and found DOS based TCP/IP software that will allow me to use my 5150 with actual Ethernet. There are a few 8bit ISA Ethernet cards that will work in the 5150 and separate executables that will configure DHCP, DNS, and even allow me to use a terminal emulator and SSH to connect to *nix based computers over lan! I'll keep you all posted!

I have a LOT of Floppies but no floppy drive that works with my current Win7 machine, and my XP one is in multiple boxes for parts... so for now I can only stare at NetWare 4 to 4.2, WfW 3.11 and DOS 6-22.

Smart me made VMs on his XP machine and transferred them to his Win7 one.

I also have data tapes... now that is NEVER gonna work on my Win7 so... anyone knows how it could *possibly* work out?

Also... I got documentation on Compaq servers... those are nice.

AAAAAAND since I’m a huge MIDI nerd... I have a SC-55mkII hooked on the UM-ONE mkII and those shitty cans that I’m gonna switch (hopefully) soon for a nice pair of Cakewalks MA-15Ds.

Also, I’m looking for one of them 5150s because 80s IBM and since I also like keyboards... the one and only Model M.

Anyone can hook me up with a cheap one?

I told you guys that I would update you on my PiBM-5150 project. I figured out the hard way that my USB to DB-25 cable wouldn't cut it. Seems it is for printers and no matter how hard I tried it wouldn't work because of the path of the wires. After researching, it is apparent that the GPIO pins on the pi are configured for serial by default but it requires a little voltage change from TTY to RS-232. Rather than do like one of the videos I saw and solder junk to a bread board, I found a serial (rs-232) shield and 9pin output for the pi. Now, both computers are true rs-232 each. Instead of using a modem between them, I bought a null modem cable (crossover of Tx Rx signals) to interface the two machines directly. I'll update this evening to show it hopefully working.

Inherited a legacy system from a previous "developer" who wrote code to sanitize input from sql injection in the front end and then called an web method called execSql which accepts am sql statement in a string value!

Obviously the app ran under admin privileges.
