Only with a 3Com label instead of the TRW label. :-) It could be used in both smart and dumb mode (with the 186 chip removed). It was usually used in dumb mode as there was never any advantage to running it in smart mode. Even if you loaded up the RAM chips on the end of the card. I'll bet I still have some of those 80186 chips sitting in a box around here somewhere. I did eventually get rid of the boards I had as I haven't seen a box with an ISA slot in over a decade. bill

If it's like the PC version, the two populated ROMS are firmware for the 80186 and the 82586. The empty socket is the boot prom.

It has been in use at STACKEN at least since the beginning of the 80ies until maybe mid nineties. STACKEN is the computer club at KTH in Stockholm. https://techworld.idg.se/2.2524/1.454545/the-stacken-story I think that some pictures are from the big computer hall I visited when studying at KTH.

I have a 3c505 somewhere but I don't think it is an Apollo one. The Linux kernel configuration help message from that era read: tristate "Apollo 3c505 support" depends on NET_ETHERNET && APOLLO help Say Y or M here if your Apollo has a 3Com 3c505 ISA Ethernet card. If you don't have one made for Apollos, you can use one from a PC, except that your Apollo won't be able to boot from it (because the code in the ROM will be for a PC). which does indeed seem to imply that the Apollo units did have the boot PROM populated, and that the only difference between the Apollo and non-Apollo variants was the bits in that PROM. I don't think the Linux device driver had any mechanism for loading firmware into the card which would also suggest that it must have had an onboard firmware PROM as well. But I'll see if I can locate my unit later and confirm that. p.
Apollo Ethernet EPROM mystery
Does anyone have a working Apollo 3C505 ISA ethernet board handy to look at? The MAME guys are trying to figure out if the boot prom and the firmware eproms are populated. There is conflicting information on the net. https://jim.rees.org/apollo-archive/photo-gallery/ether-505.jpg shows no boot prom, but I dumped a boot prom from a board a while ago with 68000 code in it, but didn't dump any firmware eproms, which would have been an odd thing to forget to do.

Re: VCF/PNW Exhibit & Trip Report - The Old Calculator Museum
Rick, thank you for exhibiting and for your glowing report! Hi, everyone, Myself and my friend Mike, representing the Old Calculator Museum, exhibited the line of Wang Laboratories electronic calculators at the Vintage Computer Federation's Vintage Computer Festival/Pacific Northwest edition, at the Living Computer Museum+Labs in Seattle, Washington this past weekend. This was the 2nd annual VCF/PNW, and it was clearly a success, as it was significantly larger than the first event last year (which I went to, but didn't exhibit at). There were 30 exhibits, all of which were really interesting, and a good-sized consignment area, as well as quite a group of guest speakers who had interesting topics to present. Of course, being held in the Living Computer Museum+Labs was a bonus, as the museum is an amazing place, with lots of vintage computers up and running and accessible for people to actually use and experience. The Old Calculator Museum exhibit consisted of a Wang LOCI-2 and punched card readers (1st and 2nd-generation card readers), a Wang 360E w/320K keyboard/display unit;362E with 370 Programmer and 371 Punched Card Reader; 360SE 4-terminal timeshared calculator package with two 360KT trig keyboards, 360K, and 320K keyboards, all running simultaneously off the 360SE electronics unit; a Wang 720C; Wang 600-14TP; Wang 500-14TP; Wang 462 and 452 Programmable calculators; and a Wang C-52. These are representatives of all of the lines of calculators that Wang Laboratories made during its years in the electronic calculator market (1965-1974). All of the machines were running and available for visitors to play with, with the exception of the LOCI-2 (which has a thermal issue that manifests after about 3 minutes of operation) and the 500-14TP, which has some kind of problem that renders it catatonic that I've not yet had a chance to try to diagnose/repair). Also shown was an original Wang Labs factory spare parts kit for the 300-series calculators & peripherals, another Wang 360SE electronics package opened up so people could see the insides, a number of circuit boards from Wang 300-series keyboard/display units, as well as core memory boards from 300-series electronics packages, core memory and circuit boards from Wang 700-series calculators, and original sales documentation for Wang's 700, 500, and 600-series calculators. The exhibit turned out pretty well, though I didn't have time to make up signs to identify the stuff until we actually got there and made hand-written signs, which turned out to be good enough -- it seems that people could actually read my chicken-scratch handwriting. The signs included the retail price at the time the machine was introduced, and people were stunned that in 1971, a Wang 720C outfitted as the exhibited machine retailed for $7,000. A lot of people asked how much that would be in today's dollars, and I was able to use my phone to find out...about $50,000. The exhibit was almost constantly busy both days for the whole time the museum was open, (10 AM - 5 PM), and the folks were all very careful with the old machines, and had really great questions about them. I was pretty surprised at how much interest there was in these old beasts. The crowd was pretty mixed in age, from folks who actually used examples of the machines in school, to youngsters who were totally shocked that this is what calculators were like 50 years ago.The machines ran the whole time the exhibit was open, and amazingly, despite the old Germanium-based transistors in the Wang 300-series calculators, as well as fussy magnetic rope ROMs and core memory in the 700 and 600-series machines, they ran trouble-free. A lot of folks had trouble getting the machines to give answers they expected because of Wang's unusual math entry method. Once they were given a simple explanation of the way the machines worked, they caught on quickly, and got answers they expected. It was a lot of fun to explain and demonstrate the machines to the visitors. The Wang 370 Programmer hooked up to the 362E electronics package was popular. I had a little program punched up on a card that would perform an iterative approximation of Pi. It'd run for 100 iterations, then stop and display the approximation it had come to thus far. People were fascinated by the "spinning" Nixie Tubes as the machine churned away on the iterations. People also liked the 360KT keyboards hooked up the 360SE simultaneous timeshared calculator electronics package. They enjoyed it when I demonstrated the two 360KT keyboard/display units running the Sine of 45 degrees at the same time. The timesharing between the two terminals was obvious as the calculator switched back and forth between each of the keyboards as the calculation, which takes about 25 seconds, was being performed. Nixie tubes were a big attraction. Many younger folks had never seen them in person before, but almost everyone knew about them. I think that the popula
