Hello All, Its been a busy week! As you can see I have been busy printing more PGM cases on my 3D printer. Once its all dialled in.. i can just keep feeding it with Filament :-)

I started the re-cap of the BBS's computer motherboard late last night. I had a few more caps to do this morning.. but its now done! If its going to run 24/7. It needs to be the best quality it can be. (I didn't just replace all the caps, i improved there size as well)

Well the dial up modems for the BBS live again! I still have to re-cap them and restore them... BUT at least they turn on :-) Its a bit tricky to work out what power supply's they need.... but its doable.

Its the end of the week... and I have been super busy as normal! I have been busy getting eproms all processed and written into complete rom sets. They are on their way to building more PGM Cave shooter carts..... It will still take another 4 to 5 weeks to complete ALL these carts.

Its Monday... so time to process more Eproms! This takes alot of time.. but it must be done. I have to Clean, Erase, Sort and Test them before any programming happens.

Hello All, More PCBs of the PAL/GAL Brute Force dumpers have arrived! If you are keen on a set of 4, Just get in contact with me. All I ask is if you can pay for postage etc. If you need more info. I did a youtube video on them the other day. www.youtube.com/watch?v=yrwR...

WANTED: Faulty "Single PCB" PGM games. (Especially "Road of the Sword"). I have wanted to do more work with these boards etc And generate more help / repair information based on them.... Its a side project. But i'll need a few boards to play with to move the project forward.

Hey Everyone! I had some time on the weekend to build the 2ND Brute Force PAL/GAL dumping PCB / Adaptor. PALs are protected and normally can't be dumped. I will be going through each PGM game cart I have and dumping ALL the PALs inside. More info is here dreamjam.co.uk/emuviews/rea...

This is around 2 ish rolls of Filament... These are RAW straight from the printer. I still need to work on them to remove like the Supports and Brims etc. Then they will be ready for more Cave "Espgaluda" PCBs.

It looks like I can 3D Print 2 complete PGM cases from 1 roll of Filament! I have bought more than 25 rolls since I got my 3D printer more than a year ago... I mainly got it with the hope that 3D Printable PGM cases would be drawn up by someone... at some stage.. and now they are!

If anyone hasn't seen the Old ST's data book. It had a very interesting "ST M27C642" 64mbit x16 Eprom. This chip was NEVER released. As far as I know. Can't find a Beta / Prototype datasheet eigher. Anyone have anymore info on this? I wonder which pin was for A21? Its still 42pin
