Aries was backordered on the required 24 and 28 pin headers needed to finish testing, and the order just came in this past week. Thus, I finally had a chance to solder and test the units. Testing went well, and I can program the units with my Willem programmer.
Originally designed to hold a 29EE512 64kB EEPROM, I found a good price on Atmel AT49F001 128kB 5V Flash, so I made the necessary adjustments and tested with the new memory. Testing went well, so I am releasing the design to production.
I have noticed one issue that I need to address. Some CBM units have an RFI shield that doubles as a heat shield. To perform the latter function, metal “fingers are stamped out of the shield that press on the top of the ICs. I need to ensure the metal shield/heat sink does not contact any of the pins on this unit.

ACID 64 Player Pro is the sequal of Acid 64 Player and is a cycle based Commodore 64 music player designed for playing SID tunes on sound cards/devices that have a real SID chip (6581/6582/8580) on board like the HardSID cards and HardSID 4U USB device.
ACID 64 emulates the MOS 6510 micro processor, the 6526 CIA chip and partially the 6569 VIC chip to run the code of a SID tune and it controls the SID chip on the device for playing the Commodore 64 music.
What’s new in version v3.0.2:
Fixes
- No error anymore when last directory was a root folder.
- Corrected memory bank setting for PSID tunes.
- Resizing window was corrupting active row of search grids.
- Minimal width is now set correctly.
Improvements
- Last played file is remembered now when ACID 64 is started.
- When Folders tab is clicked, the current selected file will always be visible.
- Special characters Ø and ø can now be searched by o or oe (re-indexing required)
- Pressing escape in search boxes will now select the text instead of clearing the input.
- Selecting a search filter will change the color of the filter box.
- Copy filename strips HVSCRoot automatically.
- Seeking (dragging thumb) can now be cancelled by pressing escape key or by pressing right mouse button.
- Scrolling search results will now update rows immediately without releasing the thumb.
- Clicking on a folder name in Folders tab will expand the folder.
- Changed “Browse” tab name to “Folders”

Sound fix diagram here. (pdf)
from Cristian Secară Homepage:
The first release (the +3) has a fatal hardware mistake: the 128K sound output is completely distorted.
- Tech explanation: the analog output of the AY-3-8912 sound chip was intended to be amplified by a one stage common-emitter transistor. In practice, they have forgot to put a resistor to the transistor’s emitter. The result: the transistor works in switch-mode – the sound is converted from analog multi-level amplitude to digitized two-level amplitude, same as the old 48K sound system.

This is a small adapter which replaces the unobtanable 6540 ROM chips used in the Commodore PET 2001-8 computers with a standard 2716 EPROM.
They will work as a drop in replacement for any ROM chip in a PET 2001-8.
