What games run on a stock CZ-600CE without internal ram?

[SomeGuy]

Howdy all , I'm new and I just made an account.

So the thing is I got my hands on an original X68000 on yahoo proxy which I have yet to ship.
Provided the battery hasn't killed the thing , I'd want to test it before I go throwing more money at it , so given its a bit tricky to get the original CZ-6BE1 ram upgrade , I was wondering what games could I run at the most bare minimum setup , so no HDD no ram , no midi , just the floppy drives and the stock system?

Maybe someone has asked this before but most people say to just upgrade , which I'm planning to eventually but id like to get it just running at all to start with , and there is a bit of a learning curve since I'm more familiar with western DOS PC's on socket 7 motherboards and the like , and not so much on systems from japan ,
so I'd be thankful for any help.

Hi @SomeGuy

I would start looking for the bits to replace the PSU. Basically a PC ATX PSU and a little logic chip for the 'Power On' signal.

From the X3 PSUs I've seen I would say it is highly likely the PSU is a leaky mess and I would personally not try it.

I've also found that there are a number of small capacitors on Disk Drives near the Power Connector which leak. So if the Disk Drives don't work that is worth looking at.

If the battery is still on the motherboard again, highly likely it's leaked and been sucked into the Main Crystal. Again there are solutions.

It's all fixable. But if your not used to fixing old computers it could be a bit daunting.

Also on OG X68K there is 1 damn screw that is accessed through the other Tower which is attached to the PSU case, so the other side also has to be stripped down. Dont refit this screw!!!

We are ready to help when it gets to you

Hey thanks for all the help so far , I'll keep those things in mind and look out for those issues, plus don't worry I'm used to repairing retro stuff , I've recapped motherboards and replaced CRT flybacks but on MS-DOS and Amiga computers.

And for sure if I run into any problems I'll let you guys know.

I've got another question for future reference

This page mentions the Sacom SX-68M MIDI card not being as compatible as the sharp CZ-6BM1 but they both have the same YM3802-X chip so what's the deal with that?

I also recommend to rebuild the PSU. When I tried to turn on my CZ-600 the first time it immediately blew the fuse inside the computer.

Yeah I plan on assembling one of those Pico PSU PCBs , especially since I want to run it on an aussie 240 volts.
