@ed1conf @mntmn Smh, I prefer writing C74 in UNIX V4 with ed(1) on my Teletype Model 43. Though, I'd love to upgrade to a Teletype Model 37.

@joe "The famous Pentium divide bug (we did not catch it but we could have)": well aren't they sophisticated.

@joe Why would anyone think it's a good idea to const-eval shifts, one bit at a time‽

@atomicpoet I had the pleasure of playing Spacewar! and singing Christmas carols with the PDP-1 at the Computer History Museum last month. And Peter Sampson, who wrote the Harmony Compiler demonstrated his pioneering computer music work. Very fun!

@elb No idea which baud rate mine is; the sticker doesn't show. I've only seen 300 baud mentioned, so it must be quite rare.

@elb That's a huge "laptop"! Sounds like a fun shop.

@elb That's the one you talked about in "The Basement" playing with at coffee shops! It's got such a tiny screen, haha.

@elb So the 703 already has a DB-25 connector and would need an external modem to connect to a remote device. Its twin model, the 707, has acoustic coupler, wall, and phone connectors and has an internal modem. I picked the 703, because I wanted RS-232 without any extra hardware. I think you're talking about the 707?

@elb I've started going after the smallest computers, until I have more space. I have a Silent 700 703 shipping, which I believe is the smallest teleprinter model. Also, I want a TRS-80 MC-10 (the smaller Color Computer precursor) and TRS-80 Model 100 or 102 (also small). Oh, and I already have a TRS-80 Pocket Computer 2. So many unrelated TRS-80 models!

@elb I've just got little stuff, but you have several big irons!

@elb I thought it was just PS/2, but it's a weird bus mouse, so I'd need to rig up a microcontroller to use it with a modern system. Feels like more work than its worth.

Easter egg on my AlphaSmart's PCB ☺︎

My VT220 :)

Before adjusting screen brightness, after, and adjusting the picture alignment before I bought it.

Haul #3: Accessories!

Obsolete Tech / Dasher Deals in SLC is unfortunately closing at the end of this year, but for now they're liquidating vintage tech at great prices.

I picked up a VT220 virtual terminal, Commodore 1541 floppy drive, TRS-80 Pocket Computer 2, AlphaSmart Pro, C.ITOH Prowriter Jr. dot matrix printer, Logitech P7-3F mouse, C64 joysticks, CoCo books, and some ribbons.
