Amiga 2000 già riparato nell’aprile 2016 ora Black Screen

Amiga 2000 already repaired in April 2016 now  Black Screen

Questo Amiga 2000 era arrivato nel mio laboratorio in pessime condizioni nel lontano Aprile 2016, il computer e’ stato riparato e riposto in una busta antistatica.

Provato a distanza di quasi 3 anni, il computer non da segni di vita.

Non avendo nessun output video ho utilizzato la DIAGROM di Chucky che tramite collegamento seriale sono riuscito a identificare 2 problemi diversi con le RAM.

Difetto:

  • Black Screen

Riparazione:

  • Ricostruita pista interrotta lato DX 68000 vicino resistor pack RP900 (precedentemente buona)
  • Ricostruita pista interrotta RAM U529 segnale CAS (precedentemente buona)
  • Sostituita RAM LM33256 U501 con TMS 4256 (precedentemente funzionante)

Di seguito un po’ di foto random della riparazione.

U64/Ultimate-64 v1.10 – U2+/U2 v3.4 Aggiornamento Firmware

E’ stato rilasciato un nuovo aggiornamento firmware per l’ultimate-64 / U2+ / U2 di Gideon.

U64 – Differences with previous official release V1.0B:

  • Based on Ultimate-II+ firmware Version 3.4
  • NTSC mode has been added. The switch can be found in the U64 Specific Settings menu
  • Added rudimentary support for USB Floppy disks (not completely done yet; as removal of floppy is not yet detected)
  • USB problems with low/full speed devices fixed; no more bus hang-ups in these cases. (No full HID support just yet..)
  • VIC collision problem fixed.
  • Improved 1541 compatibility; weak bit areas and floppy speed zones are now properly supported.
  • LED Strip support.
  • Various improvements ‘under the hood’

U2+ – Differences with previous official release V3.3a:

  • Added rudimentary support for USB Floppy disks (not completely done yet; as removal of floppy is not yet detected)
  • USB problems with low/full speed devices fixed; no more bus hang-ups in these cases. (No full HID support just yet..)
  • Improved 1541 compatibility; weak bit areas and floppy speed zones are now properly supported.
  • Various improvements ‘under the hood’

U2 – Differences with previous official release V3.2:

  • The USB2LAN problem is now fixed. This bug took me over 50 hours to find and fix.
  • Improved 1541 compatibility; weak bit areas and floppy speed zones are now properly supported.
  • All other under the hood fixes that were done for U2+ and U64 that apply for U2 are backported to the U2 as well.

SD2Snes Firmware v1.10.0/v1.10.1 released (S-DD1 support)

Ikari ha rilasciato il nuovo firmware per la SD2Snes la Flash Cartridge per Super Nintendo/Famicom. Le istruzioni per l’aggiornamento le potete trovare qui.

Cumulative Changelog:

  • S-DD1 support by Magno! Big thanks to Magno who implemented it and RedGuy who helped integrate the core with the main firmware :)
  • Support for sd2snes Mk.III (a.k.a. SD2SNES Pro). This works by adding a new set of support files for the new hardware so the firmware package actually contains two firmwares. This also makes it possible to swap the same card between old and new sd2sneses freely.
  • Fixes:
    • Fix memory corruption on BS-X loading. (Hopefully – I could not identify a cause and suspect bitstream file corruption. Please let me know if it works again – it does for me)
    • S-RTC register state is REALLY reset when the console is reset, and also when loading a game.
    • Actually boot on SD2SNES Pro.
  • Known issues:
    • Firmware seems to ignore Cx4 speed setting (at least since v1.9.0)
    • sd2snes Pro menu still has the old design
    • Mk.III specific source code changes currently aren’t contained in the GitHub repository. Please bear with me while I figure out a way to integrate them. ;)

Riparazione SNK Neo Geo MV1a con Z80 Error

SNK Neo Geo MV1a Z80 Error Repair

Riparazione SNK Neo Geo MV1a con Z80 Error.

Difetto:

  • No Sound (Z-80 Error)

Riparazione:

  • Sostituzione CPU Z-80 in formato PSOP40.

Note:

  • Il messaggio di errore “Z-80 Error” vuol dire tutto e niente, puo’ essere guasto il Z-80, SNK MASK-ROM SM1*, SNK NEO-D0 oppure anche il YAMAHA YM2610.

Con l’aiuto del Neo Diagnostics BIOS in accoppiata con la M1 ROM programmata e installata sulla CHA Board di una qualsiasi cartuccia NEO GEO si puo’ identificare meglio il problema.

Si narra che l’errore C3 / 00 che vedete nelle foto del NEO DIAGNOSTICS (scrive:C3 ma legge:00) sia un quasi certo problema della CPU. Difatti in questo caso lo era.

La CPU Z-80 in formato PSOP40 e’ stata recuperata da un SEGA GameGear guasto.

ARMSiD di Nobomi Nuovo Firmware v2.8 & nuova rev. PCB

21 February 2019 Nessun commento
ARMSid New PCB rev

Nobomi ha fatto un nuova versione dello stampato dell’ARMSiD che pero’ ha le stesse caratteristiche hardware della versione precedente.

E’ stato inoltre rilasciato da Nobomi un nuovo aggiornamento firmware per l’ARMSiD.

Qui di seguito il changelog preso direttamente dal sito.

Differences between FW 2.8 and previous version:

  • The start and the end of the bus data cycle (reading or writing) is now controlled by signal CS only (it was the same on the beginning of the cycle, but the end was controlled by 02 clock before), it can help with a bus stability in other systems than C64 a C128.
  • Internal frequency generators are updated with precision of one 02 clock – about 1us (no audio signal phase changes after frequency retuning) !
  • Correct polarity of the bandpass filter.
  • Added emulation of internal filter voltage offset.
  • Added the “Digi Boost” feature by software – an effect similar to adding 330kOhm resistor between EXTin and GND on the MOS8580.
  • Other speed optimization.

Fidelity CM14 Colour Monitor (RGB/Composite)

Fidelity CM14 Colour Monitor (RGB/Composite)

Questo Monitor veniva solitamente venduto in accoppiata con lo ZX Spectrum 128 (modelli con uscita RGN) o Sinclair QL ma puo’ funzionare con qualsiasi sorgente RGB.

Ho gia’ un modello identico nella mia collezione ma rimarchiato Prism QL14 ma senza vetro di protezione.

Il mio amico Gerben ha voluto donarmi questo modello che e’ completo di vetro di protezione. Grazie Gerben dell’ottimo imballo, il vetro come si puo’ vedere fortuntamente non si e’ rotto :D

Il test di funzionamento e’ stato fatto utilizzando l’Ultimate-64 con cavo RGB.

Ho anche eseguito una calibrazione dell’immagine video e condivido le posizioni dei trimmer sulla motherboard.

sidSwitcher Enhanced v2.02

SidSwitcher Enhanced v2.02

Progetto nato nel 2017 per il mio SX-64++

Ho voluto migliorare lo schema elettrico e fare il PCB (la versione precedente era su basetta millefori).

Inoltre ho aggiunto delle funzionalità che mi serviranno quando installero l’FPGASID nell’SX-64++ e come la versione precedente il sidSwitcher si integra perfettamente con l’Overlay-64 e il Keyman-64.

Questo circuito non e’ in vendita. Schema elettrico, Gerber e Atmel hex saranno disponibili presto per il Download.

P.S: Questo progetto puo’ anche essere utilizzato come semplice DEVIATORE (SPDT) di segnali audio analogici. 2 INGRESSI e 1 USCITA.

Funzionamento:

  • Uscita per Overlay-64 (http://henning-liebenau.de/overlay64/)
  • Ingresso Pulsante o Keyman-64 (http://henning-liebenau.de/keyman64/)
  • LED Bicolore (SID1 VERDE / SID2 ROSSO / SID1+SID2 ARANCIONE)
  • Uscita Mono o Stereo SID1 (LEFT+RIGHT / LEFT) / SID2 (LEFT+RIGHT / RIGHT) / SID1+SID2 (LEFT+RIGHT / LEFT-RIGHT)
  • Possibilita di utilizzare la funzione mute.
  • Jumper per a configurazione.
