https://www.techspot.com/news/102684-zilog-discontinuing-z80-microprocessor-after-almost-50-years.html While nothing Apple made uses the Z80 specifically, the Z85C3008VEG PLCC44 and Z85C3008PEG PDIP-40 (aka the 85C30 SCC) used in a lot of 68K Macs, is also being discontinued. If you're...

I grew up as a massive fan of the first two films (the others not so much), which was helped by the fact my mum had a very, very tiny hand in both of them as a seamstress working in the props/costuming department. While i went out of my way to try and enjoy Prometheus and Covenant, i really just...

Recently, some of you may be aware of a ban handed out to a now former member of our community. The reason for that members ban is still valid and the ban will therefore stand (Reason: Violation of the code of conduct). However, the language used in the ban message itself was not just...

This is more of a heads up - if you're building any Reloaded boards, please now be aware that TI have been curtailing their product lines, so things like the SN75150 (replaces the MC3488 in the SE Reloaded) & SN75175 RS-422/RS-485 serial interface IC's used in the SE/30 Reloaded and more, are...

This has been on the cards for a while, and i've just gotten a Dell R520 handed to me for the sum of £0 - ie, 'take it away or we're throwing it away' (perks of the job!). Oh look, here's Gary inspecting it now... To be honest, these Dell servers are more than enough for a community game...

Almost 20 years ago (jesus, that hurts to say now), I was nearly ready to begin my computing course at Middlesex University in North London. Disappointment of the course and ineptitude of the University aside, I had put together a damn good rig to handle almost everything that you could throw...

Please note - all credit goes to Phil Greenland for this: https://www.quantulum.co.uk/blog/new-timepiece-for-a-classic-mac-part-1/ https://www.quantulum.co.uk/blog/new-timepiece-for-a-classic-mac-part-2/ So for anyone with a classic mac needing the 8-pin DIP package RTC, this is the answer! I...

This year, @boopbox123 and I are eschewing the norms of british culinary tradition during the primary gifting period and choosing to instead have buffet food on the day itself, instead of boxing day, which is normally what happens. Reasons for this are mostly because we can prepare almost...

This weekend, I was thinking about the fact we're at 700+ members and some of us might also game, on some platform or another. To this end, i've made a simple spreadsheet here if you want to add yourself and open up your friends list. I've added my name to the pot already :)...

So, we're moving from a room in 2nd floor apartment, to a our own ground floor apartment with 2 bedrooms and a garden. Now, the Mrs wants to be able to have a garden space to herself and I have just the idea. In the garden is a concrete base suitable for a garden shed. This will not just be any...

I know, I know, them's is fighting words! But, i stand by this method. Pics coming soon, will edit the thread when I have some. Ingredients: Knorr Beef Stock Pot x 2 500g Minced Beef - 10 or 12% fat - just not 20, or 5 - that's too fatty/lean respectively. One large red onion (for a sweeter...

I just found this in a charity shop for £30 - a bargain if you ask me, even if it had issues. However, i picked this thing off the shelf and to my amazement, it seems to work just fine. Shutter speed, ISO, all adjustable and seem to work - the battery inside it is still chugging away! The film...

I'm having a really hard time trying to find some of the DIP DRAM's used in the 500+ Has anyone got any lurking in their stores? After any of the following: 514256 424256 514256 44C256 44C256 514256 81C4256 71C4256 514256 534256 4C4256 44256

Specifically, i'm trying to run Macintosh ROM's through it. While it can decode snippets of functions - it dumps a lot of 'data' it thinks - it can't determine what's code and what's not. Also, the references, while they line up, seem to be scattered around, and the visual graph looks like...

Well, this just fell into my lap! Literally never really thought about getting a Plus before as it seemed kinda pointless with me having an SE...well, a few/eight SE's and SE/30's in various states of being broken... However, I told myself that if i ever found one for a non-silly price, with...

Came across this today - would be ideal for anyone looking to resurrect a dead machine without having to resort to cannibalising the ever decreasing number of working machines out there. https://monotech.fwscart.com/MOS_CPU_Replacer_(65108501)/p6083514_21591072.aspx Technically it'll replace...

This will allow the use of the PLCC ADB Transceiver in the Macintosh SE, which is the only model that uses a DIP18 part. There's not much to it other than that! @Branchus has used one of these, successfully, in a troublesome SE, iirc. The github page to the project and the gerbers, is here...

After Porchy from Jammaarcade got us across the finish line with reverse engineering the original HAL16L8, i thought the functions might be possible to replicate using discrete logic. This would of course be to benefit those that are making an SE Reloaded board, who don't want to, or can't...

What differentiates the Macintosh SE from the rest of it's forebears? Well, the fact that the PAL's of the earlier 128K, 512K & Plus machines have gone away and been replaced by a single custom ASIC. The original Macintosh was designed around a single ASIC called the IBM or 'Integrated Burrell...
