Texas Instruments TI-99/4A Repair #3
Defect:
Replaced parts:
Installazione amplificatore Video per uscita Video Composita inclusa installazione dei due RCA femmina sulla scocca.
Inoltre ho efettuato un semplice fix del PAD di metallo del reset che non restava piu in posizione e di conseguenza cadeva all’interno della scocca.
Galleria:
Non si dovrebbe accendere un’Amiga spenta da circa trenta anni senza prima aver eseguito il solito Recap, ma anche eseguendo questa semplice intervento non e’ detto che tutto funzioni come ci sia aspetta.
Eseguito il Recap mi sono reso conto che l’uscita RGB / Composito e RF non funzionavano correttamente. Dall’uscita RGB mancava il colore BLU mentre il video composito e di conseguenza RF davano schermo nero.
Dopo le varie misurazioni sono arrivato alla conclusione che bisognava sostituire il DAC VP-101 (U30).
Sostituito il DAC l’uscita RGB ha ripreso a funzionare perfettamente, mentre il segnale video Composito/RF continuavano a non funzionare.
Il componente guasto per l’uscita video Composito/RF e’ la linea di ritardo Z222, bypassando la linea di ritardo sui piedini della stessa si arriva ad avere un segnale composito “decente” ma non va bene, purtroppo questo componente non e’ di facile reperibilita’, si potrebbe risolvere eseguendo un “hack” ovvero installando un diverso RGB Encoder che non ha bisogno delle linee di ritardo ed eseguendo delle modifiche sul PCB.
Il gioco vale la candela ? quando mai utilizzeremo ancora l’uscita video Composito/RF ? probabilmente mai.

E’ stato rilasciato da Nobomi un nuovo aggiornamento firmware per l’ARM2SiD.
ARM2SID firmware 3.15:
- Please don’t forget to download also a new configuration program.
- Fixed a bug with noise generation in the highest octave (reported for example in Crossroads II and Jumpman).
- SID type detection with this algorithm returns the actual type setting from the ARMSID configuration.
- Among other tracks, this allows you to play the last part of Wonderland XIII, at least if the ARMSID is set to emulate MOS6581. Prodigy rulez !
- Fixed bad music timing in Turrican 2 – The Final Fight (audible in track 2).
- Added undocumented playback of the “no” waveform, making, for example, the Boing Boom Tschak whistle significantly less (about 20dB down).
- Modifications in the generation of combined waveforms (not only) for MOS8580 emulation, where they are more close to the original (as close as possible for chips that are themselves different from each other, also dependent on temperature, voltage and time).

The return of the Hybrid Sid Player by xAD/Nightfall & Gianluca Renzi (RetroBit Lab)
Basato sul progetto di Markus Gritsch pubblicato negli anni 2011-2015 sul forum dangerousprotypes. Grazie Markus.
Changelog:
v1.22 – 6/2/2023
Note:
- From this release the new versions will be developed and tested on the v2 prototype PCB and no longer on the Breadboard prototype.
Added:
- Software implementation of the new audio Switcher.
- Added a new value (0: Nothing) to the DEFAULT_SID_SOCKET in the configuration file (config.ini).
# Choose the default SID Socket on bootup (0: Nothing – 1:Socket #1 – 2:Socket #2) – default: 1
DEFAULT_SID_SOCKET=1
- Added control via MCU of the power-up led. It might come in handy for future implementations.
Updated:
- Updated label on the oled display for the “sid switch” mode, now “sidSet” is written and not just “sid”
- Updated boot screen with the text “sorting files…” if the folder contains too many files (max 800).
Fixed:
- The encoder cannot be used for manual SID SWITCH mode in case the SID tune played is multitunes because the encoder is used to select the songs, so although the “sidset” option will be displayed on the display in this specific case the selection of the sid socket will not working.
- Logic for the switch of the Socket SID with which to play the song and the consequent LED.
- Default SID Socket if nothing is specified in the config file (config.ini)
- Manual “sid switch” mode, the SID that was played with this mode would stop after 2 minutes and start over.
E’ stato rilasciato un nuovo aggiornamento firmware per l’AVGCART (SD multicart for 8bit Atari) di tmp.
The AVGCART is a FPGA based multicart for 8bit Atari computers, extensible with SIO and/or ECI/PBI cables.
- supports CAR (cartridge dump) files up to 1MB and most bankswitching types
- supports XEX (executable) files
- supports ATR (floppy image) files (read/write) – support is limited without an optional SIO or ECI/PBI cable due to Atari cartridge port constraints (e.g. SW that uses RAM under OS does not work)
- supports ATX (protected floppy image) files (read-only, SIO cable required)
- supports CAS (cassette) files (SIO cable required)
- supports AVF (video) files
- supports PDM (audio) files
- fast file search, file shortcuts, randomizer and tons of other features
- when used with optional ECI/PBI cable, it can expand ATARI memory to up to 576kB, it can also provide extra 48kB RAM to stock 16kB 600XL machines (some limitations apply)
- firmware upgradeable via SD card (no additional hw needed)
- SIDE2 emulation (compatible with U1MB and SpartaDOS X)
- ability to stack emulated cart with emulated SpartaDOS X cart, together with SIDE2 emulated HDD
- unlike some other products, most of the functionality is running inside the cart and not on the host machine’s CPU which makes it faster and more versatile (it can do stuff in parallel with host machine without having to gain 6502 control and doesn’t require soldering extra internal upgrades like Ultimate 1MB for some basic functionality like ATR emulation or memory expansion)
- compatible with 600XL, 800XL/XE, 65XE, 130XE, XEGS (cartridge shell is too wide for 1200XL, bare pcb will fit, it is also too tall for 800, can be used with cartridge door opened and door switch triggered)
Changelog (v0028):
- Added type 75 (Atarimax 1MB “new”)
- “About” (“?”) extended to show some useful information about current state/config.
- Launching ROM files lets you choose cart type.
- Menu (“CAPS” key)
- Ability to choose bg/fg/border color.
- OS choice (PBI/ECI cable), use included rompack.rpk to flash OS slots.
- Most settings are now saved to a new config file so the old settings will be replaced with defaults.
- Some random bugs fixed, some random bugs added.

This update features (all approximates):
- 890 new SIDs
- 26 fixed/better rips
- 0 repeats/bad rips eliminated
- 217 SID credit fixes
- 25 SID model/clock infos
- 4 tunes from /DEMOS/UNKNOWN/ identified
- 0 tunes from /GAMES/ identified
- 26 tunes moved out of /DEMOS/ to their composers’ directories
- 5 tunes moved out of /GAMES/ to their composers’ directories
After this update, the collection should contain 56,665 SID files!

E’ passato diverso tempo dall’ultimo ed inutile acquisto e come i precedenti c’e’ poco da dire tutti i “mini” sono praticamente identici, cambia il contenitore, il menu e qualche chip che per l’occasione viene utilizzato l’ultimo arrivato (piu’ o meno).
Ho utilizzato un pessimo convertitore da HDMI a Video Composito per poterlo ALMENO provare con un monitor CRT.
