🌸 NAME 🌸

srec_os65v — the OS65V Loader file format, bestie! This is the srec_os65v(5) page from the File Formats Manual, and it's giving vintage Ohio Scientific loader energy. 💾✨

🦋 DESCRIPTION 🦋

Okay so this format is used by Ohio Scientific OS65V-compatible loaders. The whole family of machines is invited to the party: the OSI C1P, Superboard II, C2, C4, C8, and Challenger III, plus the UK101 and Elektor Junior. No cap, that's the crew. 👑

The file kicks off with a period '.' (0x2E) — yes, that's to ensure address entry mode. Then comes a 4-digit hex address, followed by a slash '/' (0X2F) to enter data entry mode. The initial address is always present. You don't need an extra address record unless there are gaps. 🫶

Each data byte is represented as 2 hexadecimal characters, and it's separated by a carriage return character (0x0D) — that's the advance address vibe. The final return character may be omitted. 😌

The data is concluded with a period '.' (0x2E) to re-enter address mode. If an address to start execution is specified, then the last 5 bytes are nnnnG, where nnnn is the 4-digit execution address, and G is the 'Go' command. Periodt. 💅

🎀 Size Multiplier 🎀

In general, binary data will expand in sized by approximately 3.0 times when represented with this format. That's the multiplier, bestie — not a drill. 😭

🌈 EXAMPLE 🌈

Here is an example ASCII-hex file. It contains the data Hello, World[rq] to be loaded at address 0x1000, with execution at 0x1003. (On a 6502, this is the opcode for indirect jump to 0x2C6F.) 🧚

This is exactly the example line, no edits, bestie:

1000/48^M65^M6C^M6C^M6F^M2C^M20^M57^M6F^M72^M6C^M64^M0A^M.1010G

✨ That's the whole page, bestie! Signing off from the Reference Manual, SRecord, and srec_os65v(5) — with srec_cat version 1.65 as the version energy. The footer doesn't give a date, so no invented one from me, periodt. 💖
