I've been having a great time exploring the Tandy Model 102 and the DVI.

The past few hours were spent learning the built-in terminal emulator. It's almost a VT52 but not fully so I created a new termcap for it. While it can do software flow control using xon and xoff, it's not great. To use it reliably I need to drop it to 2400 bps.

The other machine is a RaspPi. You need to turn of bracketed paste in the shell, as the Tandy has no chance of handling those codes.

In case anyone was wondering, went with the Hakko FR-301 for #desoldering - not prohibitively expensive, portable. Here it is next to the #TRS80 model 1 mainboard, ready to be tested. I'm gonna have to wait for the replacement video chips I just ordered on ebay before I get to try it out. Let's hope I'll be getting actual genuine 2102 SRAM chips. Ordered from #Poland, not #China, so fingers crossed.

Speaking of #ROMs for #ix86 / #amd64: Does anyone know a good way to implement something like #Linux in #ROM like the #Tandy #1000RL & #1000RLX did with #MSDOS & #DeskMate:

  • Or is this something that requires either going down the #PCIe -> #PCI -> #ISA rabbit hole?

I mean, it would be a way cleaner setup to boot OS/1337 to than booting a #CDROM?

  • If noone has an Idea how to make this happen, is there any good way or existing solution to basically make a hardware write-protectable / #readonly #USB flashdrive to boot from?

Ideally something that can take #BIOS-style ROM Chips that one can put on a board without write-enable connected so they're read-only!

Still having like a #minimalist #Linux distro in Boot-ROM would be nifty, espechally when it comes to making a #SecureComputing "#SSH #Terminal"...

  • Maybe @ActionRetro, @mos_8502 and others can point this question to people who are firm in boot ROMs and potentially even have something at hand.

(I don't expect something like a PCI(e Mini)Card but I'd not be against it!)
