I use a Tandy 386SX33 with SAC-201 ISA card driving a Modular Circuit Technology MOD-EMUP (or MOD-EMUP-A, I have both). I also have a BK Precision parallel port unit on it, and I have a Needham's EMP-10 I haven't put on it (as I'd need another parallel port frist:-) ).I have PC-NFS installed speaking to my Linux server where all my rom images get put (don't want to put too much faith in the old 100M internal IDE drive:-) ).I also have a DATA-I/O model 22B (actually 3 of them (I need to sell the excess:-) )).The only thing I don't have is a USB/Windows based programmer:-)Between all the ones I have, I haven't run into a device I've needed to program that I can not. Though I have not done PAL/GAL/etc, just bipolar PROMs and EPROMs.If you are into the older stuff, there is a KLOVer here who regularly sells Needham programmers complete with a laptop all setup to use. (I forget the person's handle, but you should be able to find it with a search).If you are dealing with mostly newer stuff, you'll just want to go with a 'generic' USB based programmer that has everything you would want to program on their supported device list. There are a few tricks to using the GQ-4X with older ROMs. If you have issues, you want to make sure you are using the external adapter (though that is more for writing). You also can read them out slower, and try different settings.

I rarely need to do any of those, but they have worked in the past for stubborn ROMs. For writing, you can also write multiple times. I always write them twice now (with the double write option enabled for each pass).I have an EMP-20 and a GQ-4X, and I was an avid EMP user for years.
But I haven't used my EMP in years, since I figured out the GQ-4X. Haters gonna hate, but the GQ-4X is modern and convenient, and the software is simple and great, IMO. And there's an active community to support it. It's a good value.

Are there any EPROM programmers available that work on the Mac platform? I want something that can burn 2716, 2732, 2764 and 27128 EPROMs but all the programmers I've come across run only in Windows, and I'm not sure how well they'd work under emulation/virtual emulation so native OSX support.

It's a good value.I use the gq as well. I have it setup with vbox running an instance of xp on my macbook.I always leave the adaptor connected for burning, even though only certain chips require it. Have always used double write. Its burned everything ive needed so far.
The Window XP thing.has anyone tried running this in either a virtualized instance of Windows XP (VMWare, Virtualbox, whatever) or running the application on a newer version of Windows in Compatibility Mode?you mean for the GQ-4x right? Not the GQ-4x4I've had great success with my GQ-4x, including down to 2716.
I always use external powerHere are signed drivers to run it in Windows 7 (or 8 or 10 supposedly, but I haven't bothered):the latest software, v6.38:http://www.mcumall.com/download/TrueUSBWillem/USBPrgSetup6.38.exe. Pretty sure they assume that if you can afford an overpriced Mac, you can afford to pay someone else to burn your roms for you.Not over-priced.when you consider they run for years and hold their value exceptionally well. Mine are all from 2011 - 2013 and are rock-solid.They need Mac versions.just about every software development house around runs some form of Linux or Mac's too.
I work in Silicon Valley and Windows machines are scarce.they do exist, but mostly non-technical people use them nowadays.And no one in the immediate area I am in has Windows 10. A few Windows 7's are around.I know some legacy IT departments still run Windows.I think just out of habit.I know I can use Fusion or Virtual Box.but thats kinda dumb when they can just make a Mac version and not leave out a segment of the population and force them back into Windows.

No one's made software for these programmers for years.
Take up the mantle and figure it out for yourself if you are that passionate about it.The fact of the matter is this: when these machines were in their heyday and actually supported by developers, DOS & Windows were generally considered the ONLY real business operating systems. Mac was considered more for the graphic design market and/or educational segment. In the mid 1990's I worked for the college computer labs on campus. 75% of our fleet of machines were all Apple products. There were some IBM PC compatible devices in each lab, and they were always vacant.I got issued a portable laptop for my residential networking position (I made 'house calls' to the dorms to assist students with getting on the net) and guess what they gave me?
A Windows PC. Not over-priced.macs/apples are very overpriced. For the hipster crowd.
Fanboi much?They need Mac versions.just about every software development house around runs some form of Linux or Mac's too.hyperbole. That's simply not true.I work in Silicon Valley and Windows machines are scarce.they do exist, but mostly non-technical people use them nowadays.troll. You absolutely have no proof of this.And no one in the immediate area I am in has Windows 10. A few Windows 7's are around.I know some legacy IT departments still run Windows.I think just out of habit.sigh. So much hyperbole. We need to bring in a sad panda to calm down your apples. Preface: I'm a mac user here (heh)that being said, it's not as simple as 'just make a Mac version'.
Mac OS is only about 8% (with slight fluctuations over time) of the market share for OS's out there. But even if that wasn't the case, the application would have to be almost entirely re-written from the ground up (i'm sure there's devs on KLOV that can give MUCH more insight/greater detail here)Microsoft continues to hold a near-90% market share on end user OSs. Windows is here to stay, friend.you can find a cheap PC/laptop for $50 though if you need something with Windows related to these burners. Or as others have mentioned, just virtualize it.Not over-priced.when you consider they run for years and hold their value exceptionally well.

See if you can find a Needham's EMP-20 with at least the 01A/01B, 02A/02B, and 03A/03B modules.Then grab a computer running WinXP with a parallel port, and PM me.-BradThat's what I have but I only have the 01A/01B module it has basically done everything I have ever needed it to do.What do the 02A/02B and 03A/03B modules cover?I also have a data I/O 29b with a gang pack (which is basically useless). I haven't been able to get my hands on a 2B to actually use the thing. I have at least tested the 29b at a friends place and know that works. What are all your thoughts on this?PB-10: $119.95 + $12.80 S&H: EMP-20: $149.00 + $19.00 S&H: EMP-20: $200.00 + $28.25 S&H: https://www.ebay.com/itm/NEEDHAMS-EMP-20-DEVICE-PROGRAMMER-WITH-LOTS-OF-EXTRAs/13.

I work in Silicon Valley and Windows machines are scarce.they do exist, but mostly non-technical people use them nowadays.THAT. is the funniest thing I have read all week! I think you have that backwards, the Mac people are either the non-technical or artsy people.
Real work is done on Windows boxes. We now have.one. Mac left at our site and that is for SW maintenance of old equipment.OK - I'll give you Linux being used often in software development but certainly NOT Mac.
But Windows has greatly outpaced the Linux boxes for several years.We create drivers for our products for both Linux and Windows, our Windows embedded version is highly popular. In the past 15 years, absolutely nobody has ever asked for a Mac version. CentOS, Red Hat, Fedora & plus few other flavors of Linux and Windows are the only versions we now maintain.More and more of our customers are running Windows and even the various Linux versions are dropping off. Right now - our Windows versions are being used at a rate of more than 4x the Linux versions. Systems based on the Dell R930s are selling big this month with Windows Server.
Macs are certainly used for software development. Maybe not in.NET or something.Where I work there are plenty of Macs used by developers. All but 2 people on the team I am on are using Macs.This is certainly not the case everywhere.
But we (including myself) certainly should not be making blanket statements about an entire software industry based on our personal and often local experiences.Lets leave the religious mac vs PC wars for somewhere else and get back to discussing arcade games and EPROM programmers in the case of this thread.And for anyone that cares, this was typed on a Mac, but I also have several PCs, and I run Mac, Windows, and Linux. I generally prefer Linux, Mac, and Windows in that order, but it really depends on what I'm doing.Oh, and as stated previously, my EPROM programming 'station' runs DOS:-) with my fileserver serving storage to DOS via NFS. DOS haters need not reply:-).THAT. is the funniest thing I have read all week! I think you have that backwards, the Mac people are either the non-technical or artsy people.

All his info is completely opposite ofwhat is in real life, trouby must one of those 20yo hipsters trust baby kids, privilegedwith 200k salary in the silicon valley, must be nice.An snippet from the below linked video (time from 3m:25s to 4m:02s):(https://klovimg.com/image/3qC69)6NyFRIgulPo. ^ agree ^, troubydoobydoo is trolling hard core. Oh, and as stated previously, my EPROM programming 'station' runs DOS:-) with my fileserver serving storage to DOS via NFS. DOS haters need not reply:-)DOS??? Isnt that Denial of Service?;)As in, the programmer doesnt work? HeheJust kidding.how old is your programmer?
I recall an old old one running on a Tandy Color Computer back in the 90's when i visited an old arcade repair shop in my hometown.I am also amazed you have a fileserver running NFS.Data has moved to the cloud nowadays so fileservers are seen less and less.But good stuff. I prefer to be the owner of my own data, not to whore it out to some data lake insome random country that could deny me access of it at any given time. Plus, moreimportantly, i rather not pay those assholes a monthly fee, tyvm.You'd rather just deny yourself (and all of KLOV) access, lol.what troubydoobydoo said wasn't 'false'. You may have a different opinion about your own data.
But that doesn't change the validity of what he said.). I prefer to be the owner of my own data, not to whore it out to some data lake insome random country that could deny me access of it at any given time. I don't think any cloud providers have drivers to make the contents available as a drive letter under DOS!:-)I have a Linux server, so it makes it easy for me to do NFS. It has Samba as well, but I didn't find any good software for mounting a SMB share under DOS, so being that I worked for Sun and had a copy of PC-NFS I went that route.

Makes it very easy to share files. When I want them accessible to the burner, I just scp them into place.What wasn't easy was getting pcnfsd working on a modern Linux. And I still don't have it playing with iptables and selinux. (I just temporarily disable those when I use the rom burner).

(I just temporarily disable those when I use the rom burner).I used to use LAN Manager for DOS back in the day. Was able to mount Samba shares via TCP/IP that way. Not sure if it would work with modern Samba, since the authentication back then was horribly insecure.Seconded. Now if I or somebody else could figure out how to make custom device definitions it'd also make a pretty nifty device tester:)It would need more than a custom algorithm, I think. You've have to write new software to drive it and boot it off that disk instead of the normal one.
Probably easier to start from scratch with a new design. And Isn't Mac OS X a version of BSD Unix?Yes, although over the years since OS X was released, the operating system has grown further apart from its BSD roots.The similarity to BSD is why I switched about 8 years ago. At the time, a lot of network/web engineers that I worked with were moving to Mac for the same reason. I've worked remotely in small teams for the past 6 years, so I can't comment on adoption in larger environments.
However, for the MVC/LAMP applications I have worked on over the last several years, the development teams have used Mac/Linux environments. I believe changes introduced in Win10 have helped close the gap, and going forward it is hard to tell where OS X is headed. I would say Cisco IOS powers the internet.And Isn't Mac OS X a version of BSD Unix?That little NUC that your running ESXi on is cute, but the big boys run ESXi on RAID5 in a rack mount redundant server.I am a Cisco person so, yes, Cisco hardware does primarily power the Internet.Software-wise,.nix has it. Desktops, Windows is still majority but their market share has dropped.though I think that since they gave back the start button, it helped them.LOLThis NUC is the new i7 model with 32GB of RAM.so its being used as a home test lab for when I need to scope out custom designs for customers. I work from home most days.Yep, the large customers certainly do use large, rackmount redundant servers. I would hope so.The NUC is awesome.no monitor, keyboard, mouse needed.just sits in the corner with a power cord and ethernet cable plugged in. Its a network in a box.
My programmer's BoM is roughly as follows. Prices are in UK pounds, with parts sourced from ebay. ATMEGA8-16U 1.29. USBISP programmer 1.66 (if you don't already have one). IDC 10 way box header (x10, you only need 1 for the programmer) 0.99.
USB to TTL serial converter 1.05. 74HC590 8 bit counter x2 2.77. DIP28 ZIF socket (x2 but only need 1) 0.99Plus the usual assortment of a couple of LEDs and a PCB button, but those are really optional.I've only made a programmer for the EEPROM I use, a (AT)28C256.
But the design should be adaptable to any 5V programmable parallel EEPROM up to 64KByte in size.Firmware for the AVR has only ever been built with avr-gcc, but this should be available for OS X. Client code is a trivial POSIX C program, which runs on Linux but should work on OS X if called with the appropriate serial device name.If you want any more info, let me know. I'm in the same boat as you BTW. I wanted an OS X/Linux friendly programmer and didn't want to spend much money, so I built my own. I still use it a couple of times a month, though since my micro is self-updateable it's less frequently used then it used to be.
