Thanks Jon - I was actually down your way yesterday picking these machines up just around the corner from you !

Thanks for that! Doesn't it also select RAM and ROM via G and G2B ? --- I have just examined and confirmed that my truth table is indeed...

I got one of those a while ago (Matias Quiet Pro keyboard) to use in the office. It *is* quiet, and the tactility is very nice, but the switches have...

Keep a can of Deoxit Gold and/or Krud Kutter rust inhibitor with lots of q-tips. I have five drawers full of RAM (hundreds of sticks) that I...

Dual channel mode increases bandwidth from the memory controller to the memory, yes. It will not double the bandwidth, but anywhere from 50-80% more...

Well, now with the schematic, it's all more clear :) First of all, U35 PROM only decodes the banks' RAS/CAS lines. So, if all the banks are 64k,...

I've got them as well, if you're coming down my way any time soon. Also on 3.5" disks.

Are there any proof for this? The z80's code for arithmetic can't be much faster. The only notable z80's advantage is the instructions for copying...

IMHO it is another misconception that RISC instructions are simpler than CISC ones. I has written about this in the article. The ARM's instructions...

3/24/19 I know this is not an ideal solution, but there was an older post by "gonk23" in 2015 that described his conversion from the flat white...

Dual channel mode makes a pretty big difference in performance, it more or less doubles memory bandwidth. Highly recommend you look into getting a...

Yes I am running 64bit Win7.

Possibly - with some guidance :rolleyes: I have working boot disks - do you mean a special purpose boot disk that will have a diagnostic use?...

Hi Classic, this place turned up in a search motor while looking for old familiar Alpha Micro folks.

Looks like it has CT1747, which contains an OPL3 core licensed from Yamaha. More info about SB16 -...

Not to sound racist, but all those keyboards are black, and... gosh, have USB! Anything quiet, beige, and PS/2?

QBASIC is QuickBasic without the ability to emit executable files. The result is the same as running the program within QuickBasic for debugging...

Updated further. Wish they'd extend the edit time limit from 15 mins.

There are quiet switches, silent reds, matias quiet clicks, but the construction of they keyboard and the attention paid to the stabilizers on the...

If using Windows, WinImage makes it easy to adjust images* in addition to writing the images. Shareware so if you use it on more than 30 days buying...

Take your pick

Thanks for that! I have found the schematic, which simplifies my original diagram a bit. Updated diagram here: Schematic here:...

I could be wrong but QBASIC was just a tokenized BASIC. It was not a true compiler in the sense that it would create code like a C compiler. It did...

There was a guy on E-bay selling a similar design by a company called "SteelCase" awhile ago.

Well, if I want hardware FM synthesis from a SB16 it seems I have to pay at least twice as much money, so...I might as well get wavetable synth if...
