Awesome! I wasn't sure if you'd see the web portal message as I expect it attracts a lot of crud. ๐Ÿ˜… Thanks!!

Titan III Plus IIe boardset

Titan III Plus IIe boardset

@museumjoe.bsky.social I somehow managed to lose the ICs for my Titan III Plus IIe cardset before I got around to building it. Is it at all possible to purchase a new PAL set (A5, B3, C1, C2, D1, D3, E2 and UD6)? Thanks for all that you do!

Ceramic MOS 6502 on Apple-1 replica.

Ceramic MOS 6502 on Apple-1 replica.

I managed to get a functional ceramic MOS 6502 for a fraction of what they normally go for; it was cheaper due to the faded silkscreen and solder pin reinforcement/repair on two pins. It also had some flux residue that made it less attractive (easily cleaned). #6502 #retrocomputing #apple1

Nice! I have 2-3 of those, one works great and the other one (or two) have issues as I recall.

I've never played Adventure before. This is pretty cool!

I've done that mod a few times when the PS was current but I was in my 20s.

This is apparently an AMI produced 6820, though the silkscreen is worn and illegible

I couldn't get a ceramic 6502 (well I could, but not willing to spend thousands on one) but did get a nice ceramic 6820 PIA for under $20. #mimeo #apple1 #retrocomputing #vintagecomputer

"Mimeo-1" Apple 1 replica board in progress.

I finally started working on a "Mimeo" Apple 1 replica board I bought from Mike Willegal over a decade ago ( May 2013) along with a PROM set, cassette interface and Datanetics PCB. I'm still waiting on a few parts to arrive. #retrocomputing #apple1 #mimeo1

Recently built "Snark Barker" Sound Blaster clone board. It worked first try which was a relief as some chips were bought from eBay (NE558, TEA2025B, YM3812, YM3014B, SAA1099). Finished it off with a 3D printed steel bracket from #JLCPCB. #retrocomputing #soundblaster #snarkbarker

Got one of the new MacEffects front panels for my Lisa. This is what Apple should have done back in the day. #applelisa #retrocomputing

This morning I updated a Sound Blaster 16 CT2740 from DSP v4.12 to v4.17 which corrects the hanging note bug when using the MPU401 interface or Wave Blaster header. It's pretty easy to do; unsolder the DSP, install a socket, program an 89S52 and pop it in.
