It is MY #retrocomputing pleasure to welcome the Atari Portfolio 16-bit kinda-MS-DOS-compatible handheld PC to the crew!
Powered by 3 AA batteries and coming to us from 1991, I can already tell it will fit right in.
Eventually I will be stocking up on a few choice peripherals for the Portfolio, including a system RAM memory expansion card (with peripheral port pass-through, kind of like an ur-Sonic & Knuckles experience), a serial interface, and a diagnostic interface produced for licensed repair shops and peripheral developers, all due to the diligence of a single vendor, aptly named Best Electronics, who's maintained stocks longer than the original company stayed in business.
With all your vintage computing going on its got to be a real relief that you can network them together with the contents of anyones kitchen junk drawer.
@djsundog just 30 years of discarded one-off cables and long-abandoned adapters
@Mainebot local computer store guy gave me his last null modem adapter with a look of respect and awe a few months ago, so now I am really just trying to live up to his mental image of who I must be.
