Quote from: letchuck on January 02, 2023, 05:28:19 AMSo, stas2k logged 2 times since I wrote him in PM that I'm interested into buying one but I newer got an answer. I assume then that he doesn't botter to sell them anymore. Does anybody have a clue for another memory upgrade that one cane actually buy?

Same here, no response at all. A true shame. I'd like to be able to play on my X68K that has no memory or find another feasible option.

Hello, I've just been through similar trials with ZuluSCSI (RP2040 version) and have got it working on my ACE using default config, latest ZuluSCSI 1.2.0 firmware from December '22, 4GB SDHC card formatted with FAT32, and the V4 games image using the same filename as you. I'm giving the ZuluSCSI board additional power using the floppy power connector.

Make sure the termination DIP switch is enabled on the ZuluSCSI, and also make sure your cables are good. I was connecting mine to the external centronics connector and it wasn't working, eventually I realised the cable I bought was wired upside-down (I had to file the key notch off the 50pin IDC connector so I could insert it upside down, then it was all good!)

Just wanted to confirm it does work on the SASI machines.

I have since added a 75ohm resistor to Luma ground and shield, the picture is dimmer and more distorted.

I am restoring this Sony KV-9PT50 and I decided to add a little S-Video mod to improve the picture a little bit get some practice working with CRTs/ circuits, but I am having trouble with distortion in the picture. I will include a Reddit post I made earlier for some context.

Below is a post I made to reddit's /r/crtgaming subreddit:

So this is the current issue that I'm having. I did an s-video mod on this CRT and I had everything with a very high quality picture (no distortions), but it was in black and white. I opened it up and reflowed the solder to the chroma pin in on the jungle chip and BOOM! I got color, but the picture now looks like what you are seeing.

My S-video jack chroma pin has a 1uf cap going in and a 75 ohm resistor to ground. Luma is coming from my composite video center pin with no resistance to ground.

I have everything hooked up to a switch for composite and svideo, with composite working nicely.

Any thoughts on this? It's a bit troublesome after all this toiling, so I hope to get it to work! I have been teaching myself how to do this all weekend and I have learned a lot!

I've just bought my first X68000, and I know I'll need to recap it when it arrives so I'm trying to buy the caps in advance.

Does anyone have a list of the caps for the Expert II (603c)? I've not had any luck googling it, I've found ace and expert cap lists, but not expert II. Does it use the same as the expert?

That sounds pretty much the same as what I saw in the 531. I don't remember seeing a convergence pot on the neckboard but I may have missed it.

Hey there! I do own a CZ-607 monitor and I am having the same issue. The manual refers to the remote control only, for removing the OSD. I am about to jump on Yahoo Auctions and buy a SHARP IR remote that looks like the monitor remote. If you have resolved this issue, I would be glad to know your solution. Thank you!

I'm interested in one of these too if there are any more left?
