Thanks to @gloriouscow for a link to the Epson 2KIF 8145 Y49020800000 RS-232 Serial / Current Loop interface board manual for my Epson FX-100.

Manual was key: it explained the stop bits are automatically determined by baud rate. 9600 baud has 2 stop bits. All others have 1 stop bit. Explains the bizarre behavior!

The DIPs that worked for me at 9600 8N2:
SW1 10001010
SW2 0101

Wiring (PC->Printer) hardware flow on CTS:
TX -> RX
DTR -> CTS
GND -> GND

Anyone have the manual for this Epson "2KIF" RS-232 (maybe current loop too?) serial interface board? It fits inside my Epson FX-100 wide carriage dot matrix printer as a secondary interface. I need to know what the DIP switches do. So far, I think SW2-1 through 4 are baud rate but the rest are a mystery.

EDIT: Located! See next reply.

I was recently reminded of the interesting story about how UK developers at MetaComCo saved the #AmigaOS project. The people who had originally been commissioned to create the Disk Operating System (DOS) for AmigaOS had dropped the ball, and then these guys from Bristol, UK, came over and plugged the holes with TRIPOS. Amazing interview of Dr Tim King and his wife Jessica by The Digital Orphanage: https://www.youtube.com/watch?v=pm-szurM5VY

I'm on the look-out for a Pentium Pro box/mobo that can take more than 4GB of RAM (since the Pentium Pro was the first x86 CPU that could do that).

So I'm keeping an eye out for a Data General AV8600, HP NetServer LXr Pro8, NCR Worldmark 4380, Unisys XR/6, or Axil Northbridge NX801. If anyone has leads on how to acquire any of those, or leads about other PAE-capable PPro boxes, I'd greatly appreciate it.

My Amiga AmiNet disk set

In those days you had to literally physically order your discs because the Internet connection that was available was only a 9600 BPS external Fax modem which was running at the only BBS in the country

My fax modem ran at 9600 BPS, but we only had an email connection to UUCP with the internet

My usual graphics artist and I are starting a new project for Atari ST. We're wondering whether we should aim for plain ST, or for STe and its higher capabilities, or something in between.

We need opinions, preferably from people with a bit of experience in that ecosystem.

Between the following options, intentionally ranked from easiest to hardest, where should we aim?

I need someone to test a thing for me. Could someone with access to an US Apple //c, and/or a //c+, check that the first thing this image says after loading is "60" ? https://colino.net/tmp/shflpuck-hz.po

@fozztexx maybe?

Those of you who taught yourself to code at a young age, how old were you and what language was it, and on what platform?

How would you suggest replicating the experience for current or future generations?

For me it was BASIC at about 13 years old, but I think it would have been much sooner if I had regular access to a computer sooner. I started on a used Commodore 128D but ended up on a Laser Apple II clone.

My largest hard disk drive. This beast is a 72 MB (MFM) / 105 MB (RLL) 5.25" full-height drive by #Toshiba, model MK56FB.

Next to it is another hard disk drive by Toshiba for size reference. A bit of cheating of course, as that one is only 1.8".

Remember pocket calculators with solar cells to prolong battery life? Something similar is now available as (emulated) IBM XT, built around an ESP32 and an e-ink display: https://hackaday.com/2025/04/23/the-evertop-a-low-power-off-grid-solar-gem/ #vintagecomputing #retrocomputing #esp32

Actually I need a solution that runs on Linux too as I’ll be moving this machine off Win11 at some point :/

Edit: #PCem is on Linux but on this laptop I may struggle to run a P166 #VMware is apparently available on #Linux and others have said that it’s more stable, but I don’t know what the driver situation is like; every VM vendor has abandoned 9x support — my #Win95 VM uses the #VirtualBox 6.0 drivers as those were the last to support 9x

I miss the power switches on 1980s desktop PCs. Big, red, clunky, went GA-GUNK when you flipped them. No uncertainty.
