Added a heatsink to my Beeb's video ULA as well as the CPU and 245. And here's Frenzy running from Replica now that I sorted that double stepper out.

Got my digitizer setup on my 486 and it's working in Microstation. Lot of nostalgia for this particular config.

Got one of my Sun3's open - no life yet - but they don't look too bad; look at that BBC Engineering sticker; and they're neighbouring serial numbers on the machines - these are siblings! Few fun board bodges.

Anyone know of a source for A1078 Powerbook batteries? All links I've followed have been dead/OOS and my G4 won't power on at all any more. It's a NoPowerbook :( #retrocomputing

This was my NeXT Mail avatar at that time, back in 1992. (64x64 pixels with 4 bits of each color channel per pixel (444 RGB) felt like a pretty high quality image in that era!)
The self-photo was taken in NeXT's sales office at Carillon Point in Kirkland, where Omni's founders were working as consultants (across the lake from Seattle), by hooking up a camcorder's video output to the video input on a NeXTdimension board.

I've just extracted my #suntember projects from the bottom of the pile. A pair of Sun 3/60's. They weigh 12kg each - I guess the case was designed to withstand the weight of the monitors.

Anyone familiar with DOSBox and crashes of Windows 3.11 apps?
This app installed fine but it's throwing this. I tried a few different CPU settings in DOSBox but it happens regardless if it's a 486 or Pentium or whatever.

Been working on a Toshiba Satellite T1910 (vintage laptop) which had a dodgy floppy drive. 2 drives and 2 goteks later I've worked out the issue was the flat ribbon cable I was using! 🤦‍♂️ Needs to be the twisted type; pins are reversed. Will defo write this up for other poor souls when I'm done! #retrocomputing

Screenshots of my beeb series 7 yesterday booting off my restored Cumana floppy drive. The last one, the Teletext editor is I think by my high school Maths Teacher at the time.

Today my CAD digitizer arrived. I'm going to pair that with my 486 running Microstation 5.0.
Then, unexpectedly, I went to my #retrocomputing meetup and somebody just dropped a gift for my PS/2 model 30 286 in my lap - a 386 upgrade RAM expansion card. I had no idea what it was, but it was like new and had all the manuals and disks.
[edit: actually add the pictures…

Found him! The master mouse was hiding at the back of a shelf and still works in GEM (which is pretty grim running off floppies here). This mouse plugs into the Master's User port.

Watch me clear off my dining room table and reassemble a Toshiba Satellite T2130CT from 1993.
#retrocomputing

Good; my Master is now a Master 512 again - it can see the copro OK, now I just need to find where I put the boot floppies last century. (Hmm and I wonder if we still have the mouse?)
Bonus: Interword running from the cartridge slot.
#retrocomputing

who did it best?
#retrocomputing

With the RIFAs replaced, next is the Master 512's battery pack; hmmmm - luckily the battery pack kept it away from the PCB

I had forgotten I had The Oldschool PC Font Resource installed and now I want to use every single font:

Oh hello there, you're going to be forcefully replaced:

Ooh, found my dad's slide rule; I guess I have to learn how to use it now!

My beeb series 7 was having heat problems, so I bodged some heatsinks onto the CPU and onto the infamous 245 next to it (which was getting well over 50c in a few mins)
The series 7 case has the back vent mostly covered to stop junk going in.
Hmm the wire ties aren't really satisfactory.

Did you know? IBM stands for “Itty Bitty Machines”

I also lust after the Commodore-64 version of the keyboard. Absolutely identical to the others, but that colour scheme and font!

My Acorn BBC Master 512; that's a BBC Master with an added 80186 copro (which is the board in the middle).
Hmm first time I've had the top off in ages, I guess I should check it's batteries and PSU; there doesn't seem to be any crud around the batteries.
It's got a little board from CJE which I think lets you switch in the extra EPROM sockets vs extra RAM.
#retrocomputing

I’d pour one out for VARTA today, but they’re doing that by themselves

Just typed in a RAM test program on my Series 7 BBC Model B - it passes clean; hmm - doesn't explain the instability then.
Also, I don't seem to be able to (reliably?) write to a floppy - hmm. save file, *. and find it's nto there. Hmm. Tried formatting and it's verifying bad. So some more debug todo.
(Also, hth did I type so much on a Model B keyboard, the keys are HARD)

Does anyone (in US) have a spare SCSI HDI-30 (male) to DB-25 (female) adapter or cable lying around? I'd be happy to pay postage.
It's to connect a BlueSCSI to 1990s-era PowerBooks.
(eBay sellers want fantasy prices.)

I've just learned that #8bitdo have released an #IBM #ModelM edition of their fabulous range of retro keyboards and I am definitely here for it!

This prediction from The Micro User magazine in January 1985 about where home computers might go, and how computer-touchers might still have different attitudes than the rest of the population, turns out to not actually be a thousand miles short of the mark.
