FROM DANILA’S COLLECTION

A Z80-powered workspace, brought back to life. Explore an early functional reconstruction of its banked memory, keyboard and disk system.

PROCESSOR: U880 / Z80
PROFILE: 1715W / 1715M · experimental
RUNNING: S550 · TOS/M 1.0

Loading emulator…

4× speed

Historical S550 ROM and TOS/M 1.0 disk. Power on, open Screen, and wait for A>. Try DIR.

Machine sounds (synthesized)

Drive diagnostics

Live emulated state. Index counts include pulses between display frames. Motion and RPM use the reference drive profile.

Power on to inspect drives.

Paste through the keyboard

Wait for the program’s prompt. Text is typed at a controlled pace; newlines press Enter. Printable ASCII, up to 4096 characters. Reference S600 layout only when keyboard firmware is loaded.

Record and replay a session

Restart and record captures the current disks, ROMs and subsequent keyboard, disk changes, reset and power events. Export contains that media; keep its original credits. Replay checks the display, disks and printer in a separate machine. Maximum 100,000 events and eight disk changes.

Disk library

Named copies stay in this browser. Power off to insert or reset one. Duplicate makes an independent copy; reset restores that copy’s original contents.

Keep disk changes in this browser

Writable disk copies save automatically. Export a disk for a portable backup. Machine states resume the selected machine with the same media. Older exported states can use a preserved emulator version when available.

Inspection labels

Drive B

Insert an 800 KB raw disk or a supported MFM DSK image, or start with a blank data disk. Power off to change disks; in TOS/M use DIR B: or PIP B:=A:FILENAME.

Allow writes to drive B copy

Drive B is empty.

Printer output

Printer state

Busy, offline and paper out all deassert the printer’s CTS ready signal. Software that ignores readiness can lose output; no printer-specific escape language is simulated.

Text preview interprets CR, LF, tab, backspace and page feed. Other control bytes appear as ⟦hex⟧; no particular printer’s escape language is assumed.

Virtual serial printer · raw bytes, including control codes. Capture is limited to 64 KB per session; export before clearing.

No output yet.

Display adjustments

Presentation settings for the 3D screen; these are not measured monitor potentiometer settings. The emulator’s pixels stay unchanged.

Brightness 1.00× Contrast 1.00× Phosphor persistence (illustrative milliseconds) 0 ms

Stereo placement for recorded sounds

Optional camera-relative keyboard and case placement; acoustic distances are not measured.

Try historical software

Open a fresh practice session in another tab. Its disk changes are temporary; your remembered disks stay intact.

Boot media and session disk +

Files stay in your browser. Power off before loading. Robotron needs a 2 KB boot ROM and 256-byte CAS PROM; character data is optional. Juku and VJUGA use 16 KB ROMs.

BUILT TO BE KEPT

The object. The software.
The whole story.

This is a working prototype of a long-lived collection. Historical boot media can run on the same portable cores used by our native tools. Measured cases, detailed textures and documented interiors will follow the physical collection.
