I ended up (painfully) paying $250 for the lot. It consisted of the following Silicon Graphics parts: awesome, nice deal on some sgi parts... It all came from a recycler...who forgot to mention he had already gone over the main boards and harvested all the VLSI chips.... oh :( what a ripoff instead …

interesting about those 3 points. I would have thought the clue book written for the first version of the game. strange they would later retrofit the cluebook solution points into the final version of the game. Codename Iceman could have been pretty aweome but it bogs itself down more so than even …

I need to test dosbox-x against imphobia 6+, dosbox has graphics errors on all imphobia disk mags over #6. something to do with its ega mode / colours. would be interesting to test -X and see if its any different.

Ideally I want one "base" board which has CPU, VGA, sound card, ISA controllers... then you would have "extension" boards like ISA slots, etc. lol so.. a motherboard then? :lol: basically an embedded motherboard. amd geode, or pc104 or stuff like a picmg board. its like you suddenly did a 180 from …

I have some questions though: 1) What is a negative voltage and what is it's use? 2) Why was it phased out with ISA? 3) What is the -12V used for as this still in modern PSUs? 1 - negative voltage is good for many things, rs232 serial goes from -15 to +15! its good for sound/opamps too. (this is …

so uh... it was working but you decided to shotgun all the caps, rip a cap off with pliers pulling up a pad and or tracks.. then when you put it back together its not working correctly. sometimes I think people should have a license to use a soldering iron. the only think you can do is check your …

Not strictly retro as it involves modern components but I spent a few hours today piecing together some VHDL code to recreate in a cheap FPGA board a retro machine. So far I have a Z80 CPU, 4kB of RAM and a serial port. The goal is to make a CP/M machine :) But for that I have to add some external …

get a good boot manager like System Command, it will take a lot of the pains away of opsys's fighting for boot control + bootable flags and whatnot..

Get an industrial case and use an SBC card instead of traditional 'motherboard' maybe.

So I picked up a Roland SC88VL in white... pretty nice. Nice catch. :-P Is it just me, or does that thing look brand spanking new? no some scratches on the top but the front + back is pristine (nobody hunted blindly to plug cables in). my guess, it got setup and put on a shelf and left in …

So I picked up a Roland SC88VL in white... pretty nice. Interestingly, I knew you can swap sc55/sc88 maps but I did not know you can press a button when turning the power and it will boot into CM64 mode.. I wonder if that will give me the extra sound effects like a real CM32/CM64... if I get the …

the one missing piece of the puzzle I never figured out was how the embedded interpreter knew whats sector/track/head each file was at. if one had that, we could extract everything and have it working under dos without being a booter.

yeah sure, it would be nice to know. I have not paid much attention since we got it into scummvm. I know there were improvements to sci1 stuff. I did start working on enabling the agi v1 stuff but there is magic going in in finding the files at the correct sectors on disk that I never figured out …

If you still have any interest in things AGI/SCI there are some interesting developments that have been occurring over the past year or so. cool. I've not touched agi or sci since I merged sarien into scummvm and did some odd scummvm commits years ago. These days I'm busy building my own pinball …
