Some things for Atari 8bit:

• P-COVOX is a very simple device, 4channel, discrete component digital-to-analog converter (DAC) that fits under PIA chip. It isn’t as Hi-Fi as modern sound cards, but it`s perceptiom may be a lot better than a POKEY  – especially playing MODs or NEO files
• Simple Stereo V2 – New version of the Simple Stereo now all in one. I replace my old version of Simple Stereo + U-Switch, the features are the same.
• 64k RAM Module (Replaces base ram of 64KB in all 8bit ATARI, upgrades ram in 600XL to 64KB, PCB thickness is 0,8mm)

The 64k RAM module also replaces Multiplexers, DRAM, Delay Line C060472 and so on in XL series, the Delay Line is no longer available as spare parts.

SNK Neo Geo MV1a Z-80 Error Repair.

Defect:

• No Sound (Z-80 Error)

Repair:

• Replacement of the Z-80 CPU in PSOP40 format.

Note:

• The error message “Z-80 Error” means everything and nothing, may be faulty the Z-80, SNK MASK-ROM SM1*, SNK NEO-D0 or also the YAMAHA YM2610.

With the Neo Diagnostics bios and with the M1 ROM burned and installed on the CHA Board of any NEO GEO cartridge, the problem can be better identified.

It is said that the error C3/00 that you see in the photos of NEO DIAGNOSTICS (write: C3 but reads: 00) is an almost assured a CPU problem, in fact, in this case it was.

The Z-80 CPU in PSOP40 format has been recovered from a failed SEGA GameGear.
