Boards are very clean. Cleaned with PCB detergent in an ultrasonic cleaner, then cleaned again in deionised water to rinse off the PCB detergent, then cleaned again in IPA to get rid of the water, then left in the dehydrator overnight. Checked with UV light. Packed in brand new antistatic bags...

Hi Team; Made some BlueSCSI v1.1 with a “Capcom” flavour. Blue and yellow, custom silkscreen. This is a drop-in replacement for your existing CPS3 SCSI drive. 100% tested working with my stack of various CPS3 board revisions, security cart revisions, super/ultra bioses and etc $US50 + $US15...

So much goodness hidden away in here - Ack is way to modest in his documentation - this thing is awesome. Thankyou. Couple of quick questions if I may 1) With a modified z80 test cart the main bios screen now shows these codes (SM1, M1 S1) in the top right after z80 testing. Looks like they...

Yes the RAM sticks are the SIMMS, they aren't actually RAM, they are flash chips so the data remains intact until overwritten or hit by a solar flare In order to play 3rd strike you will need 2 x 64MB SIMMS 4 x 128MB SIMMS The 64 and 128MB Simms are not interchangeable even tho they have the...

New test bios works as expected, loving the new features (and trying to figure out how they all work) If you make a defective p-rom test cart it might give an error like this - ask me how I know… New p-rom test cart working as expected after some checking As you can see I had to shoehorn...

The arrival of an MV2F with video ram error from a fellow Kind Kiwi was the kick in the pants I needed to get on with this project. For additional challenge I'll be using the cheapest eprom programmer that has any chance of working, and my own untested home-brew version of the prog board. So...

Kind of progress on the shell - these sellers are had the adapted MVS in an AES shell for sale at outrageous prices Plain black https://www.aliexpress.com/item/1005004699275681.html Plan black and translucent grey https://www.aliexpress.com/i/1005004490899386.html But if these guys are...

Greetings from across the Tasman. The 80s and 90's (and even early 00's) were a fun time for Arcade lovers down-under. Sounds like you and came away with an amazing collection and amazing memories. Lots of great Aussie and Kiwi folks here, you'll love it im sure Welcome

Could also be an interaction with the stock bios vs unibios. There are bugs in both Bioses, especially on the 4 and 6 slots boards, but the bugs manifest in slightly different ways between bioses, and between variants of the boards. So if you're experiencing inconsistent results across setups...

We kiwis are filthy grubs who never placed any value on this kind of artwork, so very little survives in this country. But I’ve always thought that if I did have an amazing collection like yours I would store it in architecture “plan draws”. Normally up to A1 in size, specifically designed for...

Cheapest and easiest CD drive replacement is the BlueSCSI 1.1; super simple to setup, the SD card is formatted just like any other mass storage device I made my own by following these instructions and wrote about it here...

Being the legend that he is, Frank silkscreened the pin assignment onto the bottom of the board.

I’m about as far from the USA as it’s possible to get, so I can’t help physically, but normally screens are like this for me Solid colour (normally green or red for me) = 68k can boot, can’t read program (because it’s encrypted) = dead battery or bad connection between a and b Black screen...

Unsorted notes part 3 - Digikey parts list Parts list for my 467 specific failed parts, as well as all the other frequently failing components. Parts list for CR-XA (this is the ver.1 variant of the adapter) End of unsorted notes part 3 - that's all I got, hope it helps

Unsorted notes part 2 - including the much coveted clear schematic PDF End of unsorted notes part 2 - part 3 with the parts list coming soon

These are my unsorted notes collected from the intertubes Start of Unsorted notes part 1 CRT rejuvenator BK precision 467 Mine needs a restore… "The G2 setting knobs under the meters independently set the G2 voltage of each gun but I found each knob had an influence on the other G2 settings...

Ouch! These guys are really expensive, and the BOM calls for 50+ of them! https://nz.mouser.com/ProductDetail/KEMET/B-06-R-25?qs=gt1LBUVyoHn1EGcP7DmcpA%3D%3D Anyone got an alternative supplier?

Getting close… as with every good project I’m missing one critical part. Despite sitting in an immense mountain of vintage electronics not one single DB9 port anywhere in the whole lot, what are the chances….

I have found my tribe of fellow Capacitor Fiddlers. Nothing beats the thrill of finding the perfect replacement cap - taking into account lead spacing, heat tolerance, lifecycle, height and diameter. Bliss.

Most of the BOM is reasonably straightforward, except for all the bits that are unobtanium and need to be salvaged from an existing board of course. I dimly, vaguely remembered some research I did ages ago in to the DIN-8 connector. This is now obsolete and mini-din-8 is often sold as din-8 for...
