This is for vector monitors only I guess?

Sccording to the manual, yes. AND for B/W-monitors...I still do not understand why b/w-monitor seem to work similiar to vector but no raster monitors :-\

Yes, it's only for vector B/W ad COLOR

Even a raster bar generator is available if you want. Small and working with just a 9V battery

Interested here (depending on price of course). ;)

Also suggest you post this over on KLOV as well (if you have not done so yet)

I would like but I'm unable to make a post on KLOV because I have not permission. I asked several times but nobody answer me...  :(

yes it's right no voltage for monitor. Did you think could be interesting to have even a power supply for the monitor?

Here the instructions

I've just let works the Wico XY Pattern Generator repro.

Schematic on the network has some inaccuracies so unluckily this first pcb release has several fixes.

Final PCB release is ready to send in production but I'm waiting to know the eventual interest.

Even enclosure will be available on request as you can see on photos even It's just a prototype and will be obviously improved.

Still don't know the exact price, just looking for interested people.

Thanks for your attention,

Piero

Excuse me but I didn't read the message until today... I'm just restoring one because I didn't own it until some days ago. Still Interstested?

What's left doesn't look like a PROM problem, more like a video address problem from the video counters given it looks like you have a repeated screen.
Paul.


Hello Paul,

I absolutely agree with you but which is the video address decoder?

Schematic seems to be unavailable. All video ram are tested and good.

May be the BPROM 6/82S140 involved on video addressing?

I dumped IC6 (82S140) and 31 (82S190) but I haven't a good dump to compare because both are not present in mame dump.

I'm unable to use my fluke (and 2650 adapter) because bus test fail (Data bit 0 and 2 or 7 tied low). I have the same issue on Astrowars and quasar but I solve the problem pulling out the 74LS244 (13E on astrowars and 3G on quasar) just to make ram/rom testing

I guess that there's a more elegant solution :)

I'm trying to repair a Quasar Zaccaria pcb.

I applied my fluke 9010th with adapter for 2650 and I did the bust test.
The fluke reports the data bit 1 tied high. Looking at the schematic I see that the 74LS244 position 3G could be responsible and not knowing how to work around this problem I removed it.
As a solution I do not absolutely love it and I would like to understand how to test the bus without removing it.
The same problem I had also met in Astro Wars. Someone would help me to understand?

Hello everybody,

from my old collection I found a Super 21 Mirco Games PCB. Unluckily some ttl is missing and no silk screen. I searched for a service manual or at least a photo but with no success.
Because in Mame is pefectly emulated, somebody must have at least one running.
Anybody can help me?
