High Voltage SID (HVSC) Collection Update #79

August 23rd, 2023 No comments

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):

  • 920 new SIDs
  • 45 fixed/better rips
  • 9 repeats/bad rips eliminated
  • 211 SID credit fixes
  • 32 SID model/clock infos
  • 3 tunes from /DEMOS/UNKNOWN/ identified
  • 1 tunes from /GAMES/ identified
  • 21 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 57,576 SID files!

Monitor TVM-10 APF Electronics, Inc.

August 12th, 2023 No comments
Monitor TVM-10 APF Electronics, Inc.

First of all, i thank my friend Gerben for giving me the monitor.

This is a Black and White monitor but for some reason a thin transparent film has been applied to the front of the cinescope to simulate the tonality of an amber cathode ray tube, furthermore the APF logo placed on the front of the monitor to the right of the power light is masked.

The TVM-10 APF Monitor is approximately 43 years old and was used with the Computer APF Imagination Machine I/II.

The Monitor had several functioning problems, below is the description of the work that has been done.

  • Removing the colored film.
  • Replacement of all electrolytic capacitors.
  • Replacement of a ceramic capacitor.
  • Horizontal synchronism calibration (H-HOLD) by delicately removing the wax that was melted inside the variable inductor.
  • Installation of a 1uf polyester capacitor in parallel with the 1.5uf one present for width adjustment horizontal (H-WIDTH) of the image, unfortunately the ferrite core inserted into the variable inductor for manual adjustment is blocked, probably with glue, forcing is not a good idea.
  • Check of the Diodes.
  • Calibration using the trimmer placed on the front of the PCB of the monitor for the power supply voltage which must be 12v.
  • Geometry adjustment.
  • General cleaning.

Only one geometry problem remains; the image on the top left side of the CRT tends to bend slightly for about 1cm and the left side of the image is slighty rounded, problem surely attributable to some polyester capacitor or resistance that has lost the capacity/value of the time.

Needless to say i checked almost all the polyester capacitors and resistors in the horizontal section and didn’t find nothing scandalous.

The photo gallery contains all the photos i made during the repair, i take this opportunity to thank a user of the plcforum who gave me tips on how to proceed with the repair.

SidPlayer+ – An standalone Psid player

July 19th, 2023 No comments
SidPlayer+ – An standalone Psid player.

Hi everyone,

I wanted to try this nice SID Player by Edu Arana with a very nice design.

Edu Arana used Bakisha opensource code for the SID (only Psid) player, the code also has my own little implementation for the Vu-Meter with three LEDs (thanks Edu for the note printed on the PCB).

I know the Bakisha SID Player fairly well, below you will find several Links of my blog where there are some experiments and implementations i did years ago.

I’m not going to dwell too much on the loyalty of this SID Player, which as i said i know well, all in all it works but we are far away light years from perfection, at least as i understand it, in fact i started another project that you all probably know: The Return of the Hybrid SID Player which in addition to an ‘almost’ perfect CPU emulation including Illegal Opcodes and uses the “Original” or “Clone” SIDs for playing music tracks and other nice and useful features.

The ‘plus’ version of the Edu SID Player differs from the previous one for the implementation of the bluetooth module which however is not supplied.

As you can see from the photos and video i have installed the BlueTooth module and the Battery to make it totally portable, the battery recharge is via USB like a mobile phone.

UPDATE:

I wrote this update because some things i wrote bothered someone.

With the phrase “I’m not going to dwell … it works well but …” i just wanted to say that the emulation of the SID, let’s talk about EMULATION, is not perfect, i’m a purist of SID songs, so for me a SID music plays perfectly only and only using the original chip, however for the price this player is sold it is perfect and also very nice!

Anyway you are always welcome to break my balls, i will always answer you.

Mini Vacuum Cleaner & Blower with Brushless Motor

June 26th, 2023 2 comments

Finally a useful object that works very well and i have tried many.

This mini vacuum cleaner (4hapa) that uses a BRUSHLESS motor (be careful when choosing which model to buy) besides the “vacuum cleaner” mode it also has the “blower” mode and i assure you that it BLOWS and quite a lot (two selectable speeds).

So finally i can finally say goodbye to compressed air spray!!!

The package includes over 4 spare filters (washable), various adapters, the USB battery charger (5v to 9v) and a bag.

The only negative note; Yes! it makes some noise! i’ll get a reason.

Digital Display Voltage Meter Bug

June 23rd, 2023 No comments
Digital Display Voltage Meter Rear

Observing these two displays at first glance there are no big differences are noticed.

Wrong! the Display where you reads V2.0 (updated version of the previous one), also works perfectly if inserted very close to the PCB of a Switching Power Supply, the other one instead at Random resets and displaying 888 just move it 10 CM away from the Switching Power Supply PCB and it works perfectly.

I wanted to share this news because i’m not the only one with this bizarre problem.

U64 (Elite)/U2/U2+/U2+L v3.10j (Core: v1.42) Firmware Update

June 22nd, 2023 No comments

A new version of the firmware for the Ultimate-64 (U64/U64E) / U2 / U2+ / U2+L by Gideon is released.

This release has again some significant changes for the firmware upgrade. Please read the manual before installing 3.10i.

Background:

If you would take some time to check the commit history of the repository at GitHub, you may find over 500 commits since the last released version, 3.10a. This is a lotttt more than it usually takes to release a next firmware version. The version is still 3.10, so there are not many functional changes. Yet, files have been touched, updated, or just made compatible with the new Ultimate-II+L hardware. It was more difficult than expected to get the Lattice FPGA to work correctly and keep compatibility with the existing hardware platforms.

On top of the new introduction of the Ultimate-II+L, there is still a need to support the “good old” 1541 Ultimate-II (or simply: U2). There have always been issues with the Microblaze processor and the compiler from Xilinx. Every version of the Xilinx compiler had different bugs that caused the Microblaze based firmware to be broken in one way or another.

Since the U2+L runs well on the Risc-V, it was decided to upgrade the CPU inside of the U2 and ditch the Microblaze forever. Unfortunately, the CPU that was chosen to run inside of the U2+L did not fit in the same space as the Microblaze clone, so I decided to write my own Risc-V compatible CPU. This is the CPU that will be used from now on in the 1541 Ultimate-II.

General Fixes:

  • [Important] Fixed ExFAT filesystems with 128kB clusters (Fixes failing D64 mounts from some ExFAT thumbdrives)
  • [Facebook Discussion] EasyFlash save function now saves all chip chunks to support incomplete CRT files
  • [Issue-271] GEORAM at boot (MarkusC64)
  • [Issue-279] Support for 2 MHz operation for any cartridge, including EasyFlash
  • [Issue-246] Fixed: Virtual Printer crashes when file cannot be created.
  • [Issue-234] Deleting last item in directory makes selection invisible
  • [Issue-236] Confirmation modal asking a question only gives ‘OK’ instead of ‘Yes/No’.
  • [Issue-R17] Added mapping of ESC key to RUN/STOP.
  • [Facebook Request] Added: Leave menu on mount (can be selected per drive)
  • [Facebook Bug Report]: Fixed starting Kingsoft Business Basic cartridge
  • [Facebook Bug Report]: Allow Maverick (and others?) to write wrong sector headers on MFM tracks.
  • [Facebook Bug Report]: Unable to select GeoRAM. Is now a mode of the RAM Expansion Unit.
  • [Facebook Bug Report]: Fixed color palette not loaded at boot (U64 only).
  • [Facebook Bug Report]: Fixed USB sticks not recognized
  • [Messenger Report]: Improvements to palette file read. Rejects faulty files. Fixes hang-up
  • [Messenger Report]: Fixes ‘Create DNP’ when run from Telnet. Turned out to be a stack overflow.
  • [Email Discussion]: Adds EEPROM segment to GMOD2 when it is missing in the CRT file

U64 core fixes:

  • Multicolor graphics side border bug (core version V1.41 => V1.42)

Modem fixes:

  • ACIA NMI pulse extension to extend over bad line. This allows the 6502 to see it always.
  • Performance optimization ACIA / Modem
  • Allow spaces after ATDT command.
  • Minor fixes in the modem emulation layer from Scott Hutter (xlar54)

Cartridge Support:

  • [Issue-314] Added support for Blackbox V9.
  • Additional C128 cartridge variant that allows banking and offers some RAM (U2/U2+/U2+L only).

Additions:

  • Firmware target added: Ultimate-II+L; the Lattice version!
  • System Information page (F4) now shows elaborate version info.
  • GEOS support functions from MarkusC64

Music LED Spectrum Analyzer (Vu-Meter)

May 31st, 2023 No comments

I have also bought a LED spectrum analyzer, very nice and impressive but certainly not suitable for professional use, but who cares!

The technical features are many and not very intuitive to be changed with just two buttons on the back.

However, I’ll summarize them very briefly:

  • Automatic detection of Microphone or Audio Input (Jack 3.5).
  • Ability to disable the clock.
  • 12 display modes.
  • 7 color modes.
  • 84 display effects can be combined.
  • 8 brightness modes.
  • Clock adjustment.
  • 4 time display modes.
  • Alarm clock function.
  • Custom RGB colors.
  • USB 5v power supply.

Below are some photos of the inside.

The reset button is very curious can cannot be reached from the outside (missing the hole) and also a Micro USB connector unusable from the outside of the case.

I attach the datasheets of the integrated circuits that are used and the manual in English language that was sent to me via email, the one available by scanning the QR Code of the product is only Chinese :-D

Apple ][ EuroPlus Repair

Apple ][ EuroPlus Repair

Apple ][ EuroPlus Repair.

Defects:

  • Black screen.
  • Power light off.
  • Keyboard does not work.

Repair:

About the black screen it was enough to press all the IC in their seat, i have removed some and cleaned the IC's socket and the IC's pins.

The Power light off, the 5v micro bulb was faulty, replaced.

The keyboard had several problems;

The keyboard connector (socket) located on the computer motherboard side was faulty and consequently are missing the -12v for the keyboard encoder PCB.

The 3 TTL chips had been replaced on the keyboard encoder PCB but 2 x 74LS04 are erroneously soldered instead of 2 x 74LS00, the third TTL was correct but not working. Replaced all.

Now everything works reasonably well, unfortunately the bad keyboard has some problems, the internal slats are warped and tend out of their seat, as a result some keys do not work correctly.

I have tried to fix and clean, but the situation hasn't improved much.
