Texas Instruments TI-99/4A Repair #3
Defect:
Replaced parts:
Video amplifier installation for Composite Video output including installation of the two female RCAs on the case.
I also made a simple fix of the metal PAD of the RESET that no longer stayed in place and consequently fell off inside the shell.

You shouldn’t turn on an Amiga that has been off for about thirty years without first running the usual Recap, but also following this simple rule it is not said that everything works as expected.
After the Recap i have realized that the RGB / Composite and RF output were not working properly.
From the RGB output the BLUE color was missing while the composite video and consequently RF show only a black screen.
After various measurements i came to the conclusion that the VP-101 (U30) DAC had to be replaced.
Once the DAC was replaced, the RGB output started working perfectly again, while the Composite/RF video signal they still didn’t work.
The failed component for the Composite/RF video output is the Z222 delay line, bypassing the delay line on the pins of the same one i have a “decent” composite signal but it’s not good, unfortunately this component is not easy to find, it could be solved by performing a “hack” i.e. by installing a different RGB Encoder that doesn’t need the delay lines and with some modifications on the PCB.
The game is worth the candle ? when will we use the Composite/RF video output ? probably never.

A new firmware update for the ARM2SiD has been released by Nobomi.
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)
Based on the Project and Hardware Schematic by Markus Gritsch released in the years 2011-2015 on the forum dangerousprototypes. Thanks 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.
A new version of the firmware for the AVGCART (SD multicart for 8bit Atari) by tmp is released.
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.

The High Voltage SID Collection (HVSC) is a freeware hobby project which organises Commodore 64 music (also known as SID music) into an archive for both musicians and fans alike.
The work on the collection is done completely in the Team and contributors’ spare time and is proudly one of the largest and most accurate computer music collections known.
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!
