Hmm, that card could be interesting for Tezro - they don't have any built-in USB ports at all. Might allow for USB keyboards/mice like the Fuel.

Hopefully it clears up for you - seems like you've had a run of bad luck concerning weather recently :)

Out of curiosity, did you notice any used electronics shops in your excursions? I seem to remember Japan passed a weird law recently regarding reselling old gear - curious as to what came out of that.

How's the noise level? Fuel-like or Onyx2-like?


More Fuel-like than Onyx; it isn't bad at all. It's probably due to the combination of the recessed front fans (the "fan wall" as SGI calls it) and the relatively slow RPM.

Ah, that sounds familiar now - you may have mentioned that to me before. Failing memory :)

deBug wrote: What was the deal with that error message anyway, missing io9?


Right - IO9 is essential to the system. In addition to providing your basic IO (console, network, SCSI, IDE) it also contains the NVRAM and TOD clock. Without a valid NVRAM the machine was unable to determine the graphics state (amongst countless other things I'd wager) and flagged the error.

I don't have a release date listing, but as far as I'm aware SGI never bumped the 7.4 base CDs. I know when I got my 7.4 compiler CD set, it shipped with base 7.4 language CDs and a separate 7.4.x patch CD to bring everything up to date.

I just bought and received the cable I need to hook up my IIgs to my Mac - I'm going to try transferring diskettes back and forth sometime this week.

If you make a backup of /unix beforehand (say, to 'unix.backup'), you'd still have a way to boot the machine if something does go awry with the kernel.

That's why you make the backup of /unix :)

To boot the backup, you'd just restart the machine, stop for system maintenance, enter the command monitor, type 'boot'. At the SASH prompt, enter "unix.backup" and go.

That's one of things I'm hoping dexter1 can eventually optimize in mplayer if he has time. Right now, it's basically impossible to play back H.264 anime smoothly even at 800MHz.

nekoneko, what exactly is the problem with mplayer's code? Optimized for 32bit machines perhaps?


It's just not optimized for MIPS. Dexter1 did extensive mplayer MIPS optimization before H.264 was added a few years ago which made an enormous difference, but the path for H.264 isn't similarly optimized at this point in time.

Not sure if anyone here can help on this, but I figured why not throw it out there. I also posted this on the Briel Computers forum since the Replica-1 uses an EEPROM rather than the 2513 character generator in the original Apple-1, so the concept may be similar.

I'm trying to adapt a 2716 EPROM (containing a character set dump from a 2513) for use in an ADM-3A. I've already programmed the 2716 with the lowercase character data, I just need to figure out the shim socket.

I do have datasheets for both chips (attached). This is what I *think* I may need to do:

Pins (2513 -> 2716):

4 - (Out 1) -> 9 (Q0)
5 - (Out 2) -> 10 (Q1)
6 - (Out 3) -> 11 (Q2)
7 - (Out 4) -> 13 (Q3)
8 - (Out 5) -> 14 (Q4)

14 - (Address 1) -> 8 (A0)
15 - (Address 2) -> 7 (A1)
16 - (Address 3) -> 6 (A2)
17 - (Address 4) -> 5 (A3)
18 - (Address 5) -> 4 (A4)
19 - (Address 6) -> 3 (A5)
20 - (Address 7) -> 2 (A6)
21 - (Address 8) -> 1 (A7)
22 - (Address 9) -> 23 (A8)

24 - (Vcc) -> 24 (Vcc)
10 (Ground) -> 12 (Vss)
11 (Chip Enable) -> 20 (G), 18 (EP)

The burning questions are whether I should start with Q0 on output (believe I have this resolved), and if G/EP should be bridged to chip enable. Or anything else I may have missed ;)

http://juliepalooza.8m.com/sl/adm3a-2.htm

Thanks much!

The /EP is basically the ChipEnable/ChipSelect, and /G is the output enable.

For a character generator those would both be wired low.


So would those both connect to pin 11 on the 2513 (chip enable), or someplace else (float)?

Quote:
Are the data words only 5 bits wide? Should be easy to see from a hexdump of the character map, I would expect all the unused bits to be all zeroes or all ones.

If they are in the bottom 5 bits you would use Q0 to Q4.


Yup, you're right - from the data sheet:

Quote:
A six-bit binary address (A4 through A9) selects 1 of 64 matrix characters arranged 5 dots horizontally and 8 dots vertically. A three bit binary address code (A1 through A3) selects 1 of 8 rows. Five outputs display a complete row of the character matrix.


Below is a partial dump of the standard 2513 ROM after running it through xxd. Based on this, I updated the pinout to use Q0-Q4. Thanks!

Possibly - I haven't tried to power it up yet. The nice thing is it came with incredibly comprehensive documentation - schematics and instructions for the IMSAI 8080 itself and every third party card in it, as well as the sales receipts for every single component in the thing, all purchased from 1975 to 1979. Yes, even tiny things like chips and caps - every single receipt! It's an amazing bit of history.

I bought the machine from Stewart Cheifet, who was the host of The Computer Chronicles, though his name isn't on the receipts so he apparently wasn't the original owner.

With all that documentation it should be pretty easy to get it up and running though - it's really clean inside.

Yep - Stewart Cheifet and Gary Kildall were the hosts through most of the eighties. I let him know I was a fan - he replied that it was a great gig that let him play with all sorts of new hardware/software.

Over the past few months there have been a number of occasions where I’ve been asked to intervene in trades gone wrong between Nekochan members.

Please keep in mind that I currently provide Nekochan as an advertisement free service - this means I haven’t seen any revenue for running Nekochan since its inception several years ago. This is partially done because I myself am not a big fan of web advertising, and if I can do a small part to minimize it – hey, that’s great stuff!

But this monetary freedom also means there is very little tethering me to the site – if I begin to perceive that Nekochan has become more of a burden then a boon due to involvement in disputes, lawsuits or what have you, I can easily walk away from it. In fact, I’d save quite a few bucks every month which I could use to buy some neat toys.

In short, if you have a problem with a trade – please, don’t bother me about it. I like to think that most people here are trustworthy and reliable, but that’s really a statistical improbability. Caveat emptor.

Thanks.

Obelix wrote: Thanks to anyone who gave me informations and advice!

Just a final note to let you people know the end of the story of my broken Fuel PSU. Remember that I had the +5V line gone up to +6V, causing the machine to auto-shut down. Other voltages were right.
Eventually, it was impossible to adapt a normal ATX power supply to the Fuel, not because of the differences in the connector pinout nor because of the insane current requirement for the +3.3V line, but because the environmental monitor *needs* a feedback signal from the PSU fan, a thing that no ATX power supply ever had. No signal means fan failure, which means auto shut off.
So I did what I should have done from day one – I had the PSU serviced by a competent technician.
It did cost me *a lot* of money, yet just a fraction of the 550$ that a well-known supplier of SGI spares charges for a new PSU. The culprit was a single IC that with its different sections individually controls each of the four voltages.
The technician went lyrical about the excellent design and the build quality of the power supply – and with good reason. Once repaired, all voltages remained constant within a few millivolts, even under extremely unbalanced loads (25 Ampere from one line, zero from the others).
I put the PSU back at work and closely monitored its behaviour for the first three hours, and all voltages remained rock-steady up to the second decimal digit. The only changing figures were the speed of the fans and the temperature of the chips. Apparently, nothing was damaged by the previous over-voltage.
And (hopefully) that’s all, folks!

Haven't forgotten to look - just haven't been to San Francisco on a shopping trip for a while. Been there a few times to pick up Craigslist stuff in the past couple months, but I'm usually in a hurry to get in there/back out before rush hour on those trips :)

One of these weekends I'll take the BART over there and poke around for a bit, see what I can come up with.

Well, I probably could have said it a little better - I was annoyed at the time :)

Basically I just wanted to get out there that I'm not the Nekochan trade ombudsman - what happens in a trade is your own business.
