"content": "So, about my Z180 build. You've seen the front panel I'm making for it, very fancy -- but what will it have on the inside? Let's talk about it.\n\nFirst, the general notion. It's not an #RC2014 system (which is no criticism of that platform, which I love and respect!). It's based on Small Computer Central's SC500 series of PCBs, which use the Z50Bus standard.\n\nMost importantly, we start with the SC503. This pint sized powerhouse packs a Z180 CPU, an ~18MHz oscillator (the Z180 can internally double that if configured to!), 512KB of SRAM, and 512KB of flash ROM. It is configured to expose the two serial ports of the Z180, and it also has a built-in SPI bus port for an SD card, usable as internal fixed disk storage with CP/M.\n\nThe ROM firmware is provided by ROMWBW, which provides various iterations of CP/M, plus a machine language monitor, a BASIC, and the UCSD P-Machine, which is its own whole OS.\n\n#retrocomputing\nhttps://studio8502.files.fedi.monster/media_attachments/files/113/137/045/389/393/401/original/d6fec74adef57b3f.jpeg\n",
