Thought it overdue for an update. I have managed to makes some progress but a mate has dumped a ton of Amiga's on my lap and bench space is at a premium. I managed to resuscitate three Amiga 2000's over the weekend only to have them blow a foo foo valve with a stuffed keyboard letting the magic smoke out. I planned to move them off the bench and get back to more important things, but alas. R914 went bango on two and I have two more that need corroded CPU sockets replaced. After that its a green screen 500 and a A3000 with issues.

I have a modern replacement motherboard coming for my 2600jr, looking forward to that one. Shouldn't take too long to get running. Famous last words....

I replaced the motherboard in my MegaST and gave it a meanwell. The RAM issues were pretty severe and a board popped up locally for a song so it was a no brainer. Just need to get a big button floppy for her and she will be apples. So now I have two working, a stock Mega and a Hot Rod Mega. MegaST's are cool but I feel a bit crippled without TOS 2.06.

The 130XE is on the back burner till I can get a modern board.

The MegaSTE is still a WIP but I need to get these other boxes off the bench to get back into it.

And finally, the ATX ST, can't get near it just yet either.

Hopefully in the next month I can chalk a couple more off. Onwards and upwards.

Righto, First aid shipment has arrived from Exxos and I've gotten on to a few issues.

Last night did Falcon recap No 1 on the CT2b bird. Considering how simple it was it still made me nervous testing it after the recap. Interestingly the two original brown caps were rooted. Works a treat. Falcon No 2 will get done tomorrow night probably.

The funky adapter arrived so I can replace the CPU socket on the MegaSTE, also plan to replace the Cache sockets as they are not in great shape. That's a big desoldering job so probably a week or two away yet. At least it runs well at 8Mhz now. Never get tired of running Flippo on it.

130XE is still awaiting a miracle when I can replace the motherboard.

ATX board I have accumulated a few more parts and probably enough to complete it. After the MegaSTE I guess.

I am 90% through a Sikorsoft 2600jr, even that was a lot more work than I anticipated. Its not working correctly yet and I've never troubleshot a 2600 before so I guess I will need to consult ye olde service manuals. Video looks good, carts running not so much.

Cyrano Jones 520STFM is on the bench for an overhaul. Recapped the PSU, dropped a Gotek in it, upgraded the ROM's replaced a stuffed shifter and repaired the MMU socket/chip. Next trick is a Exxos 4MB RAM upgrade which shouldn't be too hard.

Apart from that and the usual Amiga pile hampering its all progress for a change.

Falcon Number 2, the stock one, done. So there you go, same leaky caps on this one as the last. One of the larger ones was questionable too.
