The Usotsuki

There is a tool for sending an Apple ][ disk image over the tape port too (think it's called c2t) but I haven't used it. Also, at least on an Apple ][, DSHD disks won't hold a write reliably.

It works the same, but you enter and exit it differently.

RIFA capacitor?

The enhanced Apple //e, probably. Upgrading a //e to enhanced is apparently just a matter of switching out some ROMs and upgrading the CPU.

I was trying to come up with a Perifractic-style PCBWay joke but I'm just not clever enough. But that's a good one. 😜

I installed a 1.44 MB drive (using a standard ISA controller) in an IBM 5160. It only booted from a 720K disk; to use 1.44 MB required a BIOS patch (2m-xbios.sys) in config.sys.

I consider the Pentium/133 that I own to be "Meta-Retro" - it's old enough to be retro, but new enough to emulate most interesting systems.

In theory.

I know PC DOS 7 is capable of loading more of DOS high (DOSDATA=HIGH,UMB and COMMAND.COM /H) than MS-DOS 6. Dunno if that would help.

My old Plat had a GTE 65SC02, for what it's worth.

Yeah, the ][+ and the original //e lack the mini-assembler. (it's F666G on the original ][ and ! on the 65C02 systems.)

It is. Some AMD 5x86s are marked "X5" and some are marked "486DX5".

A shame, I bet the C64 could do a really nice game of Joust given the Apple ][ version.

The earliest Integer ][s did have only 4 colors in hi-res mode. But that was an update within the model (like DHGR support on the //e).

They should be on Asimov and/or in 4am's collection of clean cracks.
