@AlgoCompSynth That would be muLisp, as I ran across quite by accident the other day. Sure enough, it's amazing on the #200LX! I've been working on Project Euler: it's quite addictive.

I can't believe it, but I found an old-arse CF card of 32MB size and made it work in my 200LX! Now, DOOM8088....and a ton of other games. #retro #retrocomputing #retrogaming #retrogames #200lx #msdos
Bonus shots of the phone-HP file transfer process. #hp200lx #retrocomputing #200lx
HP Connectivity Pack is now installed on my phone, allowing me to view and convert files from the #hp200lx's native PIM apps. Phone and HP #200LX are now a self-sufficient pair, with no PC required to transfer, view or edit files. (And yes, I also have Lotus 1-2-3 on my phone. Who doesn't?) No lock-in, no bullshit, just data files in well-understood formats readable anywhere. Can it still be called #retrocomputing if it's still so useful in the modern age?
The next #Forth program I write on the HP #200LX will be #uuencode / #uudecode so I can transfer binary files to/from hosts that don't support #zmodem. #HP200LX
i also have guides for the #200LX but i was unable to keep the actual device and didn't realize the manuals were in the same pile until i got stateside lol
omg I was not expecting winning #Freecell on the HP #200LX to do the bouncy cards thing

I bought a large storage card for the #HP200LX. Sadly, the HP itself is the only machine I have working right now with a PC card slot. The card came preloaded with neat #200LX-ready software, which I am backing up to my PC. Copying hundreds of megabytes of software over 9600 baud serial... takes... um... a while!?

literally all of you were wrong.

no spoilers from you lot, i'm doing a YouTube video on this thing and it WILL go into great detail

#retrocomputing #200lx

I feel like a new world is being opened to me. I am finally getting in touch with what my body truly desires; I feel as though a centuries-long, intimate, carnal yearning is finally being fulfilled.

I can finally carry an IBM PC XT with CGA-compatible graphics in my pocket.
